Thorson,
       
        JA:—This
      
      is
      an
      appeal
      from
      a
      judgment
      of
      the
      Divisional
      Court,
      
      
      dismissing
      the
      appellant’s
      application
      for
      judicial
      review
      of
      a
      decision
      
      
      made
      by
      the
      Minister
      of
      Revenue
      for
      Ontario,
      refusing
      to
      refund
      to
      the
      appellant
      
      
      an
      alleged
      overpayment
      of
      tax
      which
      it
      claims
      to
      have
      made
      under
      
      
      
        The
       
        Retail
       
        Sales
       
        Tax
       
        Act,
      
      RSO
      1970,
      c
      415,
      as
      amended,
      as
      a
      result
      of
      two
      
      
      payments
      of
      tax
      which
      it
      made
      on
      February
      23,
      1973
      and
      April
      23,
      1973,
      
      
      respectively.
      
      
      
      
    
      The
      total
      of
      the
      two
      payments
      was
      $492,218.
      This
      was
      the
      amount
      which
      
      
      the
      appellant
      had
      estimated
      to
      be
      payable
      by
      it
      as
      tax,
      according
      to
      its
      
      
      calculation
      of
      the
      taxable
      value
      of
      certain
      tangible
      personal
      property
      that
      
      
      had
      been
      included
      in
      the
      purchase
      price
      of
      a
      sulphur
      recovery
      plant
      which
      
      
      the
      appellant
      had
      purchased
      in
      the
      transaction
      giving
      rise
      to
      liability
      for
      tax.
      
      
      
      
    
      Some
      months
      after
      it
      made
      the
      two
      payments,
      the
      appellant
      decided
      that
      
      
      it
      had
      overstated
      the
      taxable
      value
      of
      the
      tangible
      personal
      property
      in
      
      
      question,
      and
      in
      1974,
      pursuant
      to
      subsection
      2(8)
      of
      the
      Act
      as
      it
      then
      read,
      
      
      it
      made
      a
      claim
      for
      a
      refund.
      In
      due
      course,
      it
      received
      a
      refund
      of
      the
      full
      
      
      amount
      claimed
      by
      it.
      
      
      
      
    
      In
      May
      of
      1975,
      on
      still
      further
      reflection,
      the
      appellant
      again
      decided
      
      
      that,
      even
      taking
      into
      account
      the
      refund
      it
      had
      claimed
      and
      received
      in
      
      
      1974,
      it
      had
      still
      paid
      more
      tax
      in
      1973
      than
      it
      should
      have,
      and
      on
      June
      13,
      
      
      1975
      it
      applied
      for
      an
      additional
      refund.
      The
      Minister
      refused
      to
      consider
      the
      
      
      appellant’s
      application,
      on
      the
      ground
      that
      subsection
      2(8)
      of
      the
      Act,
      as
      it
      
      
      had
      by
      then
      been
      amended
      with
      effect
      from
      April
      8,
      1975,
      left
      the
      Minister
      
      
      with
      no
      authority
      to
      consider
      the
      application
      or
      to
      make
      any
      refund
      of
      taxes
      
      
      based
      on
      it,
      inasmuch
      as
      the
      application
      made
      on
      June
      13,
      1975
      was
      not
      
      
      made
      within
      two
      years
      from
      April
      23,
      1973,
      the
      date
      of
      the
      final
      payment
      of
      
      
      tax
      made
      by
      the
      appellant
      in
      that
      year.
      
      
      
      
    
      In
      1973,
      when
      the
      tax
      in
      question
      was
      paid
      by
      the
      appellant,
      the
      applicable
      
      
      provision
      of
      
        The
       
        Retail
       
        Sales
       
        Tax
       
        Act
      
      governing
      the
      making
      of
      
      
      refunds
      of
      tax
      in
      the
      circumstances
      with
      which
      we
      are
      here
      concerned
      was,
      
      
      as
      it
      still
      is,
      subsection
      2(8)
      of
      the
      Act.
      At
      that
      time
      subsection
      2(8)
      contained
      
      
      no
      limitation
      period
      during
      which
      a
      claim
      for
      a
      refund
      need
      be
      made.
      
      
      Rather,
      it
      provided
      only
      that
      the
      Treasurer
      of
      Ontario
      “may”
      refund
      any
      overpayment
      
      
      of
      tax
      upon
      receipt
      of
      satisfactory
      evidence
      that
      the
      amount
      paid
      
      
      as
      tax
      was
      “wrongfully
      paid”.
      In
      1974,
      the
      wording
      of
      subsection
      2(8)
      was
      
      
      changed
      in
      certain
      respects
      which
      are
      not
      material
      to
      this
      appeal,
      except
      
      
      that
      the
      “Treasurer
      of
      Ontario”
      became
      the
      “Minister
      of
      Revenue”.
      In
      April
      
      
      of
      1975,
      however,
      a
      major
      change
      was
      made
      in
      subsection
      2(8)
      affecting
      its
      
      
      substance.
      As
      a
      result
      of
      this
      change,
      the
      subsection
      thereafter
      provided
      
      
      that
      the
      amount
      of
      any
      overpayment
      of
      tax
      made
      by
      a
      person
      “shall
      be
      
      
      refunded
      if,
      within
      two
      years
      following
      the
      date
      of
      payment
      of
      such
      amount,
      
      
      an
      application
      for
      the
      refund
      is
      made
      to
      the
      Minister
      and
      it
      is
      established
      
      
      within
      such
      two
      years
      to
      the
      satisfaction
      of
      the
      Minister
      that
      the
      amount
      
      
      that
      may
      be
      refunded
      was
      not
      payable
      as
      tax
      under
      this
      Act”.
      
      
      
      
    
      As
      a
      result,
      the
      appellant
      was
      met
      with
      the
      argument
      that
      because
      its
      application
      
      
      for
      a
      refund
      of
      tax
      was
      not
      made
      on
      or
      before
      April
      23,1975,
      the
      application
      
      
      could
      not
      be
      considered
      or
      acted
      upon
      by
      the
      Minister.
      It
      would
      
      
      follow,
      of
      course,
      that
      by
      May
      of
      1975,
      when
      the
      appellant
      apparently
      first
      
      
      came
      to
      realize
      that
      it
      might
      have
      a
      claim
      to
      an
      additional
      refund,
      the
      time
      
      
      for
      asserting
      its
      claim
      was
      already
      past.
      Indeed,
      it
      was
      already
      past
      by
      April
      
      
      24,
      1975,
      the
      day
      on
      which
      the
      amendment
      to
      subsection
      2(8)
      received
      royal
      
      
      assent,
      since
      the
      amendment
      was
      deemed
      by
      the
      1975
      amending
      legislation
      
      
      to
      have
      come
      into
      force
      on
      April
      8,1975,
      sixteen
      days
      before
      it
      received
      
      
      royal
      assent.
      
      
      
      
    
      In
      May
      of
      1978,
      the
      appellant
      brought
      its
      application
      for
      judicial
      review
      of
      
      
      the
      Minister’s
      decision
      before
      the
      Divisional
      Court,
      having
      been
      advised
      by
      
      
      the
      Minister
      that
      this
      was
      the
      appropriate
      method
      for
      testing
      the
      matter
      
      
      before
      the
      courts.
      The
      ground
      stated
      by
      the
      appellant
      in
      its
      application
      for
      
      
      judicial
      review
      was
      that
      the
      Minister’s
      refusal
      of
      a
      refund
      was
      based
      on
      the
      
      
      erroneous
      legal
      conclusion
      that
      the
      appellant’s
      right
      to
      apply
      for
      a
      refund
      
      
      expired
      on
      April
      23,
      1975,
      and
      that
      payment
      of
      the
      refund
      was
      therefore
      
      
      precluded
      by
      law.
      Essentially
      the
      position
      taken
      by
      the
      appellant
      before
      the
      
      
      Divisional
      Court
      was
      that
      it
      had
      a
      right,
      under
      the
      terms
      of
      subsection
      2(8)
      
      
      as
      it
      was
      before
      the
      1975
      amendment,
      to
      a
      refund
      of
      any
      amount
      which
      
      
      could
      be
      established
      to
      have
      been
      overpaid
      by
      it,
      and
      that
      the
      1975
      amendment
      
      
      imposing
      a
      limitation
      period
      did
      not
      operate
      to
      take
      away
      that
      right.
      
      
      
      
    
      In
      support
      of
      this
      position,
      the
      appellant
      argued
      that
      in
      the
      pre-1975
      formulation
      
      
      of
      subsection
      2(8),
      the
      word
      “may”
      ought
      in
      its
      context
      to
      be
      read
      
      
      as
      “shall”.
      That
      is
      to
      say,
      the
      word
      “may”
      ought
      not
      to
      be
      considered
      as
      
      
      merely
      permissive,
      in
      the
      sense
      of
      connoting
      a
      discretion
      in
      the
      Minister,
      
      
      but
      rather,
      in
      its
      context
      in
      the
      statute
      in
      which
      the
      word
      appeared,
      as
      mandatory
      
      
      or
      imperative.
      In
      the
      terms
      in
      which
      this
      argument
      has
      been
      put
      in
      
      
      the
      appellant’s
      statement
      before
      this
      Court,
      the
      appellant
      sought
      to
      rely
      on
      
      
      the
      “well-recognized
      canon
      of
      construction”
      (so
      described
      in
      
        Craies
       
        on
      
        Statute

      ed.)
      1971

      285,
      quoting
      from
      a
      statement
      of
      Lord
      Cairns
      in
      
      
      
        Julius
      
      v
      
        Bishop

        Oxford

      that
      “where
      a
      power
      is
      
      
      granted
      by
      statute
      to
      a
      public
      officer
      for
      the
      purpose
      of
      being
      used
      for
      the
      
      
      benifit
      of
      certain
      persons
      if
      certain
      conditions
      are
      met,
      the
      courts
      will
      require
      
      
      that
      power

      “shall”.”
      
      
      
      
    
      On
      this
      premise,
      it
      was
      argued
      before
      the
      Divisional
      Court,
      the
      appellant
      
      
      had
      a
      right
      to
      a
      refund
      which,
      even
      if
      it
      had
      not
      accrued
      before
      the
      1975
      
      
      amendment,
      was
      at
      least
      “accruing”
      by
      that
      time,
      so
      that
      applying
      the
      principle

      the
      repeal
      of
      the
      earlier
      version
      of
      
      
      subsection
      2(8)
      by
      the
      1975
      amendment
      cannot
      be
      construed
      as
      affecting
      
      
      that
      right,
      in
      the
      absence
      of
      language
      in
      the
      amending
      legislation
      indicating
      
      
      a
      contrary
      intention.
      Accordingly,
      the
      appellant
      submitted,
      the
      Minister
      was
      
      
      under
      a
      duty
      to
      refund
      the
      amount
      of
      tax
      in
      question
      upon
      being
      satisfied
      
      
      that
      there
      was
      in
      fact
      an
      overpayment,
      even
      although
      the
      application
      for
      refund
      
      
      was
      not
      made
      until
      after
      the
      1975
      amendment.
      
      
      
      
    
      The
      Divisional
      Court
      dismissed
      the
      application
      for
      judicial
      review
      of
      the
      
      
      Minister’s
      decision.
      Mr
      Justice
      Galligan,
      speaking
      for
      the
      Court,
      was
      of
      the
      
      
      opinion
      that
      a
      reading
      of
      the
      pre-1975
      provisions
      of
      the
      Act
      indicated
      that
      it
      
      
      was
      the
      intention
      of
      the
      Legislature
      in
      fact
      to
      confer
      upon
      the
      Minister
      a
      
      
      discretion
      as
      to
      whether
      or
      not
      a
      refund
      would
      be
      made
      in
      the
      circumstances
      
      
      of
      any
      particular
      case.
      He
      noted
      that
      in
      the
      pre-1975
      legislation,
      
      
      the
      subsection
      immediately
      preceding
      subsection
      2(8)
      also
      dealt
      with
      
      
      the
      subject
      of
      refunds,
      yet
      that
      subsection
      provided
      that
      in
      the
      case
      of
      a
      
      
      payment
      of
      tax
      made
      in
      the
      special
      circumstances
      described
      therein,
      “such
      
      
      payment
      shall
      be
      refunded”
      on
      evidence
      that
      the
      tax
      was
      wrongfully
      paid.
      In
      
      
      Mr
      Justice
      Galligan’s
      view,
      the
      use
      of
      the
      word
      “shall”
      in
      subsection
      2(7),
      
      
      contrasted
      with
      the
      use
      of
      the
      word
      “may”
      in
      subsection
      2(8),
      made
      it
      appeal
      
      
      that
      the
      Legislature
      intended
      the
      Minister
      to
      have
      a
      discretion
      and
      that
      
      
      when,
      in
      1975,
      the
      would
      “shall”
      replaced
      the
      word
      “may”
      in
      subsection
      
      
      2(8),
      it
      must
      be
      taken
      that
      the
      Legislature
      intended
      to
      remove
      from
      the
      
      
      Minister
      the
      discretion
      which
      it
      had
      previously
      intended
      him
      to
      have.
      
      
      
      
    
      Mr
      Justice
      Galligan
      then
      concluded
      that
      the
      right
      of
      the
      appellant
      to
      
      
      “seek
      the
      exercise
      of
      a
      discretion
      in
      its
      favour”
      is
      not
      an
      accrued
      right,
      nor
      
      
      it
      it
      a
      “vested
      right”
      (presumably
      in
      the
      sense
      of
      a
      right
      which
      could
      be
      
      
      argued
      to
      be
      unaffected
      by
      the
      1975
      amendment).
      In
      the
      result,
      in
      his
      opinion,
      
      
      the
      limitation
      period
      in
      the
      1975
      amendment
      applied
      to
      bar
      the
      appellant’s
      
      
      claim
      for
      refund,
      and
      the
      Minister
      was
      correct
      in
      law
      in
      refusing
      to
      
      
      consider
      the
      claim.
      
      
      
      
    
      On
      the
      appeal
      to
      this
      Court,
      and
      in
      response
      to
      questions
      put
      by
      
      
      members
      of
      the
      Court
      designed
      to
      clarify
      what
      this
      Court
      took
      to
      be
      two
      
      
      alternative
      positions
      advanced
      by
      the
      appellant,
      counsel
      for
      the
      appellant
      
      
      Stated
      his
      position
      to
      be
      as
      follows:
      
      
      
      
    
      1.
      If
      this
      Court
      were
      to
      accept
      his
      argument
      that
      the
      word
      “may”
      in
      the
      
      
      pre-1975
      version
      of
      subsection
      2(8)
      means
      “shall”,
      then
      the
      appellant
      is
      
      
      entitled
      to
      a
      refund
      of
      tax
      as
      claimed
      by
      it
      upon
      producing
      evidence
      
      
      satisfactory
      to
      the
      Minister
      as
      to
      the
      amount
      of
      the
      overpayment
      made
      by
      
      
      it,
      since
      the
      appellant
      had
      either
      an
      accrued
      or
      an
      accruing
      right
      to
      a
      refund
      
      
      in
      that
      case,
      which
      right
      was
      unaffected
      by
      the
      repeal
      of
      the
      legislation
      
      
      by
      which
      the
      right
      was
      conferred.
      
      
      
      
    
      2.
      Alternatively,
      if
      this
      Court
      were
      to
      reject
      his
      argument
      that
      “may”
      
      
      means
      “shall”
      in
      the
      pre-1975
      version
      of
      subsection
      2(8),
      then
      the
      appellant
      
      
      is
      entitled
      to
      have
      the
      Minister
      at
      least
      consider
      its
      application
      for
      
      
      a
      refund
      and
      either
      accept
      it
      or
      reject
      it
      based
      on
      considerations
      that
      are
      
      
      proper
      considerations
      to
      be
      applied
      in
      reaching
      a
      decision
      thereon,
      since
      
      
      the
      appellant
      had
      either
      an
      accrued
      or
      an
      accruing
      right
      to
      have
      its
      application
      
      
      considered
      on
      that
      basis
      upon
      producing
      evidence
      satisfactory
      
      
      to
      the
      Minister
      as
      to
      the
      amount
      of
      the
      overpayment
      made
      by
      it,
      and
      since
      
      
      that
      right
      was
      similarly
      unaffected
      by
      the
      repeal
      of
      the
      legislation
      by
      
      
      which
      it
      was
      conferred.
      
      
      
      
    
      In
      considering
      these
      alternative
      positions,
      I
      propose
      to
      deal
      first
      with
      the
      
      
      argument
      that
      the
      word
      “may”
      in
      the
      pre-1975
      version
      of
      subsection
      2(8)
      
      
      should
      read
      as
      “shall”.
      
      
      
      
    
      In
      my
      opinion,
      the
      Divisional
      Court
      was
      correct
      in
      its
      conclusion
      that
      the
      
      
      word
      “may”
      in
      the
      above
      context
      was
      permissive
      only
      and
      was
      not
      to
      be
      
      
      taken
      to
      mean
      “shall”.
      I
      agree
      with
      the
      reasoning
      by
      which
      Mr
      Justice
      
      
      Galligan
      reached
      that
      conclusion.
      It
      was,
      in
      my
      opinion,
      clearly
      open
      to
      the
      
      
      Divisional
      Court
      to
      draw
      the
      inference
      which
      it
      did
      from
      the
      contrasting
      
      
      language
      of
      subsection
      2(7)
      and
      subsection
      2(8)
      and
      to
      look
      to
      the
      presumed
      
      
      intention
      of
      the
      Legislature
      in
      1975
      when
      it
      amended
      subsection
      2(8)
      
      
      as
      it
      did.
      In
      this
      latter
      regard
      I
      do
      not
      accept
      that
      the
      “deeming”
      provisions
      
      
      of
      sections
      17
      and
      18
      of
      
        The
       
        Interpretation
       
        Act
      
      can
      be
      invoked,
      as
      counsel
      
      
      for
      the
      appellant
      has
      suggested,
      somehow
      to
      make
      it
      “improper”
      for
      a
      court
      
      
      to
      seek
      assistance,
      in
      arriving
      at
      a
      conclusion
      as
      to
      the
      previous
      state
      of
      the
      
      
      law,
      by
      looking
      to
      the
      presumed
      intention
      of
      the
      Legislature
      in
      amending
      
      
      the
      law
      in
      the
      way
      in
      which
      it
      has.
      
      
      
      
    
      I
      do
      not,
      however,
      disagree
      with
      the
      proposition
      that
      in
      certain
      circumstances
      
      
      the
      word
      “may”
      in
      a
      statute
      must
      indeed
      to
      be
      taken
      to
      mean
      
      
      “shall”.
      In
      some
      contexts,
      of
      course,
      the
      word
      “may”
      is
      neither
      necessarily
      
      
      permissive
      nor
      necessarily
      imperative,
      but
      rather
      merely
      empowering.
      Its
      
      
      function
      is
      to
      empower
      some
      person
      or
      authority
      to
      do
      something
      which,
      
      
      otherwise,
      that
      person
      or
      authority
      would
      be
      without
      any
      power
      to
      do.
      In
      
      
      such
      a
      case,
      the
      word
      “may”
      merely
      removes
      an
      impediment
      to
      the
      doing
      of
      
      
      that
      thing,
      leaving
      it
      open
      to
      be
      determined,
      in
      the
      context
      of
      the
      legislation
      
      
      in
      question,
      whether
      or
      not
      the
      Legislature
      intended
      that,
      where
      the
      conditions
      
      
      if
      any
      prescribed
      for
      the
      exercise
      of
      the
      power
      are
      met,
      the
      power
      will
      
      
      in
      fact
      be
      exercised.
      
      
      
      
    
      Examples
      of
      such
      empowering
      “mays”
      occur
      with
      some
      frequency
      in
      our
      
      
      revenue
      laws
      and
      in
      other
      statutes
      which
      contain
      provisions
      for
      making
      
      
      payments
      out
      of
      the
      Consolidated
      Revenue
      Fund
      of
      the
      Province,
      since
      it
      is
      
      
      fundamental
      that
      no
      payment
      may
      be
      made
      out
      of
      the
      duties
      and
      revenues
      
      
      raised
      by
      the
      Province
      which
      form
      its
      Consolidated
      Revenue
      Fund
      except
      
      
      by
      or
      with
      the
      authority
      of
      the
      Legislature.
      Thus
      any
      refund
      of
      tax
      which
      
      
      calls
      for
      a
      payment
      out
      of
      the
      Consolidated
      Revenue
      Fund
      necessarily
      requires
      
      
      either
      the
      Legislature’s
      permission
      or
      the
      Legislature’s
      direction
      to
      
      
      make
      the
      payment.
      
      
      
      
    
      As
      already
      mentioned,
      however,
      it
      is
      the
      context
      in
      which
      this
      kind
      of
      empowering
      
      
      language
      appears
      that
      will
      determine
      whether
      the
      legislation
      is
      to
      
      
      be
      construed
      as
      permissive
      or
      imperative.
      For
      the
      reasons
      already
      mentioned,
      
      
      I
      am
      satisfied
      that
      in
      the
      pre-1975
      formulation
      of
      subsection
      2(8)
      of
      
      
      
        The
       
        Retail
       
        Sales
       
        Tax
       
        Act,
      
      the
      intention
      was
      to
      confer
      a
      discretion
      on
      the
      
      
      Minister
      to
      make
      or
      refuse
      to
      make
      a
      refund.
      That
      said,
      however,
      it
      is
      clear
      
      
      that
      the
      discretion
      conferred
      on
      the
      Minister
      was
      not
      one
      which
      may
      be
      exercised
      
      
      capriciously
      or
      arbitrarily.
      Rather,
      it
      was
      a
      discretion
      which
      may
      be
      
      
      exercised
      only
      on
      proper
      principles,
      and
      only
      on
      the
      basis
      of
      such
      considerations
      
      
      as
      may
      properly
      be
      taken
      into
      account
      by
      the
      Minister
      in
      
      
      assessing
      the
      merits
      of
      a
      particular
      claim.
      
      
      
      
    
      Although
      I
      therefore
      conclude
      that
      the
      appellant
      in
      this
      case
      had
      no
      right
      
      
      to
      a
      refund
      of
      the
      overpayment
      which
      it
      claimed
      to
      have
      made,
      there
      remains
      
      
      to
      be
      considered
      the
      alternative
      position
      taken
      by
      counsel
      for
      the
      appellant,
      
      
      namely,
      that
      it
      had
      a
      right,
      either
      accrued
      or
      accruing,
      to
      have
      its
      
      
      claim
      considered
      by
      the
      Minister,
      even
      if
      the
      end
      result
      of
      such
      consideration
      
      
      might
      be
      that
      the
      claim
      was
      rejected.
      Coupled
      with
      this
      position,
      of
      
      
      course,
      is
      the
      appellant’s
      assertion
      that
      the
      1975
      amendment
      did
      not
      have
      
      
      the
      effect
      of
      taking
      away
      that
      right.
      
      
      
      
    
      Mr.
      Justice
      Galligan,
      speaking
      for
      the
      Divisional
      Court,
      dealt
      with
      this
      
      
      argument
      very
      briefly
      in
      the
      following
      two
      sentences:
      
      
      
      
    
        The
        decision
        of
        the
        Judicial
        Committee
        of
        the
        Privy
        Council
        in
        
          Director
         
          of
         
          Public
        
          Works
         
          and
         
          Another
        
        v
        
          Ho
         
          Po
         
          Sang
         
          and
         
          Others,
        
        [1961]
        2
        All
        ER
        721
        is
        authority
        that
        
        
        the
        right
        to
        seek
        the
        exercise
        of
        a
        discretion
        in
        one’s
        favour
        is
        not
        an
        accrued
        right.
        
        
        I
        likewise
        think
        that
        the
        right
        to
        seek
        the
        favourable
        exercise
        of
        a
        discretion
        in
        
        
        one’s
        favour
        is
        not
        a
        vested
        right.
        
        
        
        
      
      With
      great
      respect,
      I
      think
      the
      learned
      Divisional
      Court
      judge
      erred
      in
      
      
      equating
      the
      “right”
      with
      which
      the
      
        Ho
       
        Po
       
        Sang
      
      case
      was
      concerned
      with
      
      
      that
      which
      is
      asserted
      by
      the
      appellant
      in
      its
      alternative
      position
      here
      
      
      described,
      and
      in
      applying
      the
      reasoning
      in
      the
      
        Ho
       
        Po
       
        Sang
      
      case
      to
      reach
      
      
      the
      conclusion
      he
      reached
      on
      the
      facts
      of
      this
      case.
      
      
      
      
    
      In
      the
      
        Ho
       
        Po
       
        Sang
      
      case
      the
      Judicial
      Committee
      was
      concerned
      with
      a
      
      
      Hong
      Kong
      ordinance
      which
      authorized
      the
      tenants
      of
      a
      lessee
      of
      lands
      
      
      leased
      from
      the
      Crown
      to
      appeal,
      by
      way
      of
      petition
      to
      the
      Governor
      in
      
      
      Council
      of
      Hong
      Kong,
      against
      any
      proposal
      of
      the
      Director
      of
      Public
      Works
      
      
      to
      issue
      a
      re-building
      permit
      to
      such
      a
      lessee
      entailing
      the
      demolition
      of
      existing
      
      
      structures
      on
      the
      leased
      lands.
      The
      Crown
      lessee
      had
      sought
      such
      a
      
      
      permit
      and
      the
      tenants
      had
      filed
      a
      petition
      against
      the
      Director’s
      proposal
      
      
      to
      issue
      it,
      when
      the
      relevant
      provisions
      of
      the
      ordinance
      were
      repealed
      
      
      without
      any
      express
      provision
      being
      made
      enabling
      consideration
      to
      be
      
      
      given
      to
      the
      subsequent
      issue
      of
      the
      certificate
      then
      sought
      or
      to
      any
      pending
      
      
      petitions
      against
      its
      issue.
      Some
      time
      thereafter,
      however,
      the
      Governor
      
      
      in
      Council
      directed
      that
      a
      rebuilding
      certificate
      be
      issued
      by
      the
      Director,
      
      
      and
      the
      tenants
      sought
      a
      declaration
      that,
      after
      the
      repeal,
      the
      Director
      had
      
      
      no
      authority
      to
      issue
      such
      a
      certificate.
      
      
      
      
    
      The
      Judicial
      Committee
      held
      that
      at
      the
      time
      when
      the
      relevant
      provisions
      
      
      of
      the
      ordinance
      were
      repealed,
      the
      lessee
      had
      no
      “right”
      under
      the
      
      
      repealed
      legislation
      which
      was
      capable
      of
      being
      preserved
      by
      the
      provision
      
      
      of
      the
      Interpretation
      Ordinance
      of
      Hong
      Kong
      corresponding
      to
      paragraph
      
      
      14(1
      )(c)
      of
      
        The
       
        Interpretation
       
        Act
      
      of
      this
      Province.
      In
      their
      Lordships’
      view,
      
      
      the
      lessee’s
      entitlement
      to
      have
      its
      cross-petition
      against
      the
      petition
      of
      its
      
      
      tenants
      considered
      by
      the
      Governor
      in
      Council
      was
      not
      such
      a
      right.
      The
      
      
      issue
      of
      whether
      or
      not
      the
      lessee
      would
      be
      given
      a
      re-building
      certificate
      
      
      “rested
      in
      the
      future’’
      and
      its
      outcome
      could
      not
      be
      known
      until
      the
      matter
      
      
      had
      been
      considered
      by
      the
      Governor
      in
      Council.
      In
      the
      words
      of
      Lord
      Morris
      
      
      of
      Borth-y-Gest,
      at
      731:
      
      
      
      
    
        The
        lessee
        had
        no
        more
        than
        a
        hope
        or
        expectation
        that
        he
        would
        be
        given
        a
        rebuilding
        
        
        certificate,
        even
        though
        he
        may
        have
        had
        grounds
        for
        optimism
        as
        to
        his
        
        
        prospects.
        
        
        
        
      
      Shortly
      thereafter
      a
      more
      general
      observation
      is
      made:
      
      
      
      
    
        It
        may
        be
        ..
        .
        that,
        under
        some
        repealed
        enactment,
        aright
        has
        been
        given
        but
        that,
        
        
        in
        respect
        of
        it,
        some
        investigation
        or
        legal
        proceeding
        is
        necessary.
        The
        right
        is
        
        
        then
        unaffected
        and
        preserved.
        It
        will
        be
        preserved
        even
        if
        a
        process
        of
        quantification
        
        
        is
        necessary.
        
          But
         
          there
         
          is
         
          a
         
          manifest
         
          distinction
         
          between
         
          an
         
          investigation
         
          in
        
          respect
         
          of
         
          a
         
          right
         
          and
         
          an
         
          investigation
         
          which
         
          is
         
          to
         
          decide
         
          whether
         
          some
         
          right
        
          should
         
          or
         
          should
         
          not
         
          be
         
          given.
        
        On
        a
        repeal,
        the
        former
        is
        preserved
        by
        the
        Interpretation
        
        
        Act.
        The
        latter
        is
        not.

        added)
        
        
        
        
      
      Although
      counsel
      for
      the

        singhe,
      
      [1964]
      AC
      541
      held
      that
      a
      person
      could
      “acquire
      a
      right’’
      against
      
      
      someone
      pursuant
      to
      legislation
      even
      though
      that
      right
      might
      be
      called
      “inchoate’’
      
      
      or
      “contingent”,
      and
      that
      accordingly
      the
      Divisional
      Court
      erred
      in
      
      
      accepting
      the
      Privy
      Council’s
      earlier
      decision
      in
      the

      case
      as
      
      
      determinative
      of
      the
      issue
      in
      the
      present
      case,
      I
      do
      not
      think
      it
      is
      necessary
      
      
      to
      attempt
      to
      distinguish
      the
      
        Ho

      basis,
      in
      order
      to
      
      
      make
      the
      point
      that
      his
      alternative
      position
      ought
      not
      to
      have
      been
      rejected
      
      
      by
      the
      Divisional
      Court
      on
      the
      reasoning
      of
      the
      
        Ho
       
        Po

      The
      
        Ho
       
        Po
       
        Sang
      
      case
      has
      been
      considered
      and
      applied
      in
      a
      number
      of
      
      
      Canadian
      cases.
      One
      of
      these

      (1971),
      65
      CPR
      1,
      which
      involved
      an
      appeal
      to
      the
      Exchequer
      Court
      of
      
      
      Canada
      from
      a
      grant
      of
      a
      licence
      under
      the
      
        Patent
       
        Act.
      
      One
      of
      the
      issues
      
      
      was
      whether
      the
      respondent,
      upon
      filing
      its
      application
      for
      a
      licence,
      had
      an
      
      
      accrued,
      or
      alternatively
      an
      accruing,
      right
      to
      such
      licence
      on
      the
      ground
      
      
      that,
      as
      argued
      by
      counsel
      for
      the
      respondent,
      “by
      making
      the
      application
      it
      
      
      had
      done
      all
      that
      was
      required
      as
      a
      statutory
      condition
      of
      its
      obtaining
      a
      
      
      licence”.
      Thurlow,
      J
      concluded
      on
      this
      point
      that,
      as
      in
      the
      
        Ho
       
        Po
       
        Sang
      
      
      
      case,
      “what
      the
      applicant
      had
      .
      .
      .
      was
      nothing
      more
      than
      a
      hope”.
      He
      then
      
      
      went
      on,
      however,
      to
      add
      the
      following
      observation
      at
      12:
      
      
      
      
    
        Nor
        do
        I
        think
        what
        the
        respondent
        had
        at
        that
        state
        [ie
        before
        the
        decision
        on
        the
        
        
        application
        was
        made]
        can
        be
        regarded
        as
        an
        “accru-ing”
        right
        (or
        privilege)
        within
        
        
        the
        meaning
        of
        paragraph
        36(c)
        [the

      the
      real
      problem
      
      
      in
      this
      case.
      On
      April
      8,
      1975
      when
      the
      1975
      amendment
      to
      subsection
      
      
      2(8)
      of
      
        The
       
        Retail
       
        Sales
       
        Tax
       
        Act
      
      was
      stated
      to
      have
      become
      effective,
      did
      the
      
      
      appellant
      have
      a
      “right”
      which
      the
      law
      will
      recognize
      as
      such?
      If
      so,
      is
      it
      a
      
      
      right
      which
      is
      protected
      by
      paragraph
      14(1)(c)
      of
      
        The
       
        Interpretation
       
        Act
      
      as
      
      
      being
      one
      which,
      at
      that
      time,
      either
      had
      “accrued”
      or
      was
      “accruing”
      in
      the
      
      
      appellant’s
      favour?
      
      
      
      
    
      In
      my
      opinion
      the
      appellant
      did
      have
      such
      a
      right.
      It
      arose
      by
      virtue
      of
      the
      
      
      pre-1975
      legislation,
      which
      in
      my
      opinion
      clearly
      contemplated
      that
      a
      claim
      
      
      for
      a
      refund
      or
      tax
      could
      be
      asserted
      by
      a
      taxpayer
      in
      the
      situation
      of
      the
      ap-
      
      
      pellant,
      and
      that
      such
      a
      claim
      would,
      when
      it
      was
      received
      by
      the
      Minister,
      
      
      be
      considered
      by
      the
      Minister
      even
      if,
      as
      previously
      noted,
      the
      end
      result
      of
      
      
      such
      consideration
      might
      be
      that
      the
      claim
      was
      rejected.
      
      
      
      
    
      There
      is
      no
      dispute
      that
      the
      appellant
      paid
      the
      tax
      here
      in
      question.
      Having
      
      
      paid
      an
      amount
      as
      tax
      in
      excess
      of
      what
      it
      could
      then
      or
      subsequently
      
      
      establish
      by
      satisfactory
      evidence
      to
      be
      the
      amount
      which
      in
      law
      it
      was
      required
      
      
      to
      pay,
      it
      had
      a
      right,
      which
      was
      not
      limited
      in
      time
      by
      the
      then
      applicable
      
      
      law
      governing
      refunds,
      to
      advance
      a
      claim
      to
      the
      Minister
      to
      have
      
      
      the
      amount
      of
      the
      overpayment
      refunded
      to
      it,
      and
      to
      have
      its
      claim
      considered
      
      
      and
      either
      accepted
      or
      rejected
      by
      the
      Minister,
      applying
      the
      principles
      
      
      and
      taking
      into
      account
      the
      considerations
      properly
      applied
      and
      
      
      taken
      into
      account
      by
      her
      in
      the
      exercise
      of
      the
      discretion
      which
      she
      had
      to
      
      
      make
      or
      refuse
      to
      make
      such
      a
      refund.
      
      
      
      
    
      Given
      that
      the
      Minister’s
      discretion
      in
      the
      matter
      was,
      at
      most,
      a
      limited
      
      
      discretion
      as
      already
      mentioned,
      I
      do
      not
      think
      it
      can
      be
      said
      that
      what
      this
      
      
      appellant
      had
      was
      “no
      more
      than
      a
      hope
      or
      expectation”
      such
      as
      the
      Crown
      
      
      lessee
      was
      found
      to
      have
      had
      in
      the
      
        Ho
       
        Po
       
        Sang
      
      case.
      That
      case
      is
      clearly
      
      
      distinguishable
      from
      the
      present
      case
      as
      regards
      the
      nature
      of
      the
      right
      
      
      asserted,
      and
      in
      my
      opinion
      the
      decision
      in
      the
      
        Ho
       
        Po
       
        Sang
      
      case
      does
      not
      
      
      apply
      to
      bar
      this
      appellant
      from
      succeeding
      on
      the
      basis
      of
      the
      alternative
      
      
      position
      stated
      and
      argued
      by
      counsel
      on
      its
      behalf.
      
      
      
      
    
      In
      reaching
      this
      conclusion,
      I
      am
      not
      unmindful
      of
      the
      fact
      that
      in
      1974,
      
      
      when
      the
      appellant
      first
      claimed
      and
      received
      a
      refund,
      the
      appellant
      must
      
      
      be
      presumed
      to
      have
      been
      in
      full
      possession
      of
      all
      of
      the
      facts
      and
      information
      
      
      on
      the
      basis
      of
      which
      it
      later
      applied
      for
      an
      additional
      refund,
      after
      the
      
      
      time
      provided
      therefore
      under
      the
      1975
      amendment
      had
      gone
      by.
      In
      this
      
      
      regard
      there
      is,
      in
      my
      opinion,
      no
      evidence
      that
      in
      1974
      the
      Ministry
      or
      its
      officials
      
      
      misled
      the
      appellant
      or
      that
      they
      were
      somehow
      at
      fault
      in
      not
      then
      
      
      drawing
      to
      the
      attention
      of
      the
      appellant
      that
      it
      should
      alter
      its
      claim
      to
      include
      
      
      the
      full
      amount
      which
      it
      claimed
      the
      following
      year.
      If
      fault
      is
      to
      be
      
      
      found,
      the
      fault
      appears
      to
      lie
      with
      the
      appellant,
      who
      overpaid
      the
      tax
      
      
      under
      a
      misapprehension
      as
      to
      its
      liability
      in
      law
      to
      do
      so
      and
      who
      failed
      to
      
      
      appreciate
      the
      full
      extent
      of
      its
      mistake
      until
      more
      than
      two
      years
      later.
      
      
      
      
    
      Nor
      am
      I
      unmindful
      that
      in
      this
      particular
      case
      no
      claim
      for
      refund
      was
      
      
      outstanding
      before
      the
      Minister
      at
      the
      time
      when
      the
      legislative
      provision
      
      
      which
      gave
      rise
      to
      the
      asserted
      right
      was
      repealed
      by
      the
      legislature
      in
      
      
      favour
      of
      another,
      very
      different,
      legislative
      regime
      governing
      such
      refunds.
      
      
      Counsel
      for
      the
      respondent
      on
      this
      appeal
      pressed
      the
      point
      during
      his
      
      
      argument
      that
      the
      existence
      of
      such
      an
      outstanding
      claim,
      whether
      or
      not
      it
      
      
      took
      the
      form
      of
      what
      would
      now
      be
      termed
      an
      “application”,
      was
      at
      least
      a
      
      
      minimum
      requirement
      to
      be
      met
      before
      any
      “right”
      to
      or
      in
      respect
      of
      a
      refund
      
      
      could
      be
      found
      in
      the
      appellant’s
      favour.
      Without
      any
      such
      claim
      having
      
      
      been
      in
      fact
      made,
      he
      argued,
      how
      could
      it
      be
      said
      that
      whatever
      right
      
      
      the
      applicant
      had
      was
      more
      than
      merely
      theoretical?

      case,
      it
      is
      to
      be
      noted,
      there
      was
      at
      least
      a

      and
      counter-petition

      case
      there
      was
      at

      a

      that

      the
      Commissioner
      
      
      of
      Patents.
      
      
      
      
    
      While
      I
      would
      be
      prepared
      to
      accept
      that
      in
      other
      circumstances
      there
      
      
      might
      well
      be
      some
      force
      in
      such
      an
      argument,
      I
      have
      nevertheless
      concluded
      
      
      that
      it
      cannot
      prevail
      in
      the
      unusual
      circumstances
      in
      which
      this
      appellant
      
      
      found
      itself
      as
      a
      result
      of
      the
      1975
      amendment
      to
      s
      2(8)
      of
      the
      Act.
      
      
      Although
      both
      counsel
      on
      this
      appeal
      referred
      the
      Court
      to
      various
      cases
      in
      
      
      which,
      in
      other
      jurisdictions,
      an
      
        Interpretation
       
        Act
      
      provision
      similar
      to
      
      
      paragraph
      14(1)(c)
      of
      the
      Ontario
      Act
      was
      considered
      and
      applied
      by
      the
      
      
      courts
      of
      those
      jurisdictions,
      neither
      counsel
      was
      able
      to
      refer
      us
      to
      any
      
      
      case
      in
      which
      such
      a
      provision
      was
      considered
      or
      applied
      in
      a
      situation
      
      
      comparable
      to
      this.
      In
      this
      case,
      if
      one
      were
      to
      accept
      the
      respondent’s
      
      
      argument,
      whatever
      right
      the
      appellant
      could
      have
      asserted,
      if
      it
      had
      
      
      become
      aware
      “in
      time”
      that
      it
      has
      a
      right
      which
      could
      be
      asserted,
      vanished
      
      
      entirely
      as
      a
      result
      of
      the
      1975
      amendment.
      Furthermore,
      whatever
      
      
      right
      the
      appellant
      could
      have
      so
      asserted
      disappeared
      even
      before
      that
      
      
      amendment
      received
      royal
      assent.
      In
      the
      result,
      therefore,
      the
      appellant
      
      
      could
      not
      possibly
      have
      sought
      to
      apply
      for
      a
      refund
      under
      the
      provisions
      of
      
      
      the
      amended
      law
      without
      immediately
      being
      met
      by
      the
      argument
      that
      the
      
      
      time
      limited
      for
      the
      making
      of
      such
      an
      application
      had
      already
      passed.
      
      
      
      
    
      Nor
      can
      I
      agree
      that
      because
      no
      claim
      for
      a
      refund
      was
      outstanding
      at
      the
      
      
      time
      of
      the
      1975
      amendment,
      whatever
      right
      the
      appellant
      had
      at
      that
      time
      
      
      was
      merely
      “theoretical”.
      A
      right
      is
      no
      less
      a
      right
      recognized
      by
      the
      law
      
      
      solely
      because
      all
      of
      the
      steps
      necessary
      to
      be
      taken
      before
      it
      can
      be
      acted
      
      
      upon
      may
      not
      yet
      have
      been
      taken.
      In
      this
      case
      the
      right
      to
      claim
      a
      refund
      
      
      came
      into
      being
      once
      the
      overpayment
      of
      tax
      had
      been
      made.
      At
      that
      time
      
      
      there
      was
      no
      restriction
      in
      the
      law
      on
      the
      time
      within
      which
      the
      claim
      could
      
      
      be
      advanced;
      as
      already
      noted
      it
      was
      not
      until
      the
      1975
      amendment
      that
      a
      
      
      limitation
      was
      added
      doing
      away
      with
      the
      right
      of
      a
      taxpayer
      to
      seek
      a
      refund
      
      
      of
      tax
      more
      than
      two
      years
      after
      the
      date
      of
      payment
      of
      such
      tax.
      
      
      
      
    
      Quite
      clearly,
      under
      the
      pre-1975
      version
      of
      subsection
      2(8),
      the
      Minister
      
      
      could
      not
      be
      required
      or
      expected
      to
      act
      upon
      a
      claim
      for
      refund
      until
      the
      
      
      person
      asserting
      the
      claim
      had
      provided
      to
      the
      Minister
      “satisfactory
      
      
      evidence
      that
      the
      amount
      was
      wrongfully
      paid”.
      As
      I
      see
      it,
      however,
      this
      
      
      was
      essentially
      an
      evidentiary
      requirement,
      just
      as
      it
      continues
      to
      be
      an
      
      
      evidentiary
      requirement
      under
      the
      amendment
      legislation
      that
      the
      Minister
      
      
      must
      be
      satisfied
      that
      “the
      amount
      that
      may
      be
      refunded
      was
      not
      payable
      
      
      as
      tax
      under
      this
      Act”.
      
      
      
      
    
      In
      my
      opinion
      it
      is
      not
      necessary
      for
      this
      Court
      to
      involve
      itself
      in
      drawing
      
      
      fine
      distinctions
      as
      to
      whether
      the
      right
      which
      the
      appellant
      had
      at
      the
      time
      
      
      of
      the
      repeal
      in
      question
      was
      an
      “accrued”
      right
      or
      merely
      an
      “accruing”
      
      
      right
      within
      the
      meaning
      of
      paragraph
      14(1)(c)
      of
      
        The
       
        Interpretation
       
        Act.
      
      
      
      Although
      I
      think
      it
      may
      properly
      be
      said
      to
      be
      a
      right
      which,
      in
      all
      essential
      
      
      respects,
      accrued
      to
      the
      appellant
      at
      the
      time
      the
      overpayment
      was
      made,
      
      
      the
      right
      here
      found
      reaches
      beyond
      the
      claiming
      of
      the
      refund
      to
      include
      as
      
      
      well
      the
      right
      to
      have
      the
      claim
      for
      refund
      considered
      and
      either
      accepted
      or
      
      
      rejected
      by
      the
      Minister.
      To
      the
      extent
      that
      it
      can
      be
      argued
      on
      this
      basis
      
      
      that
      the
      right
      did
      not
      fully
      mature
      until
      the
      evidentiary
      requirements
      for
      its
      
      
      consideration
      by
      the
      Minister
      were
      met,
      I
      would
      be
      prepared
      to
      accept
      that
      
      
      it
      was
      an
      “accruing”
      right.
      Certainly
      I
      do
      not
      think
      it
      is
      helpful
      to
      seek
      to
      
      
      categorize
      it
      in
      other
      terms,
      for
      example
      as
      to
      whether
      it
      was
      an
      “inchoate”,
      
      
      “conditional”
      or
      “contingent”
      right.
      Nor
      does
      it
      assist
      to
      categorize
      it,
      as
      
      
      did
      the
      learned
      Divisional
      Court
      judge,
      as
      not
      being
      a
      “vested”
      right.
      These
      
      
      terms
      tend
      to
      obscure
      what
      Thurlow,
      J,
      in
      the
      passage
      quoted
      earlier,
      pinpointed
      
      
      as
      the
      real
      difficulty
      in
      this
      kind
      of
      case,
      which
      is
      to
      determine
      
      
      whether
      there
      is
      “anything
      that
      answers
      to
      the
      description”
      of
      the
      word
      
      
      “right”
      in
      the
      applicable
      
        Interpretation
       
        Act
      
      legislation.
      
      
      
      
    
      In
      reaching
      the
      above
      conclusion
      as
      to
      the
      outcome
      of
      this
      appeal,
      I
      wish
      
      
      to
      make
      it
      clear
      that
      I
      express
      no
      view
      on
      whether,
      in
      the
      circumstances
      of
      
      
      this
      case,
      the
      appellant
      is
      entitled
      to
      succeed
      in
      its
      claim
      for
      a
      refund
      on
      the
      
      
      merits.
      That
      is
      a
      matter
      for
      the
      Minister
      to
      decide,
      and
      this
      Court
      will
      not
      interfere
      
      
      with
      the
      exercise
      of
      the
      Minister’s
      discretion
      so
      long
      as
      it
      is
      exercised
      
      
      on
      proper
      principles
      and
      on
      the
      basis
      of
      considerations
      properly
      
      
      taken
      into
      account
      by
      her
      in
      that
      regard.
      In
      disposing
      of
      this
      appeal
      it
      is
      
      
      neither
      necessary
      nor
      desirable
      for
      this
      Court
      to
      attempt
      to
      spell
      out
      those
      
      
      principles
      and
      considerations.
      Equally
      it
      is
      unnecessary
      to
      express
      any
      
      
      view
      on
      the
      question,
      which
      was
      raised
      during
      the
      hearing
      of
      the
      appeal,
      as
      
      
      to
      whether
      s
      2(8)
      of
      the
      Act,
      as
      amended
      in
      1975,
      would
      preclude
      a
      taxpayer
      
      
      from
      pursuing
      some
      other
      avenue
      of
      legal
      recourse
      for
      the
      recovery
      of
      an
      
      
      overpayment
      where
      the
      overpayment
      resulted
      not
      from
      a
      mistake
      of
      law
      on
      
      
      the
      part
      of
      the
      taxpayer,
      as
      appears
      to
      be
      the
      case
      here,
      but
      rather
      from
      a
      
      
      mistake
      of
      fact.
      
      
      
      
    
      For
      the
      reasons
      given
      I
      am
      of
      the
      opinion
      that
      the
      appeal
      should
      be
      allowed.
      
      
      Paragraph
      2
      of
      the
      order
      of
      the
      Divisional
      Court
      dated
      June
      15,
      1979
      
      
      should
      be
      set
      aside,
      and
      in
      its
      place
      there
      should
      be
      an
      order
      declaring
      that
      
      
      Minister
      of
      Revenue
      is
      under
      an
      obligation
      in
      law
      to
      receive
      and
      consider
      
      
      the
      appellant’s
      claim
      for
      a
      refund
      of
      tax
      under
      
        The
       
        Retail
       
        Sales
       
        Act,
      
      and
      to
      
      
      take
      such
      action
      on
      the
      claim
      as
      is
      then
      indicated,
      in
      accordance
      with
      the
      
      
      reasons
      for
      judgment
      of
      this
      Court
      herein.
      
      
      
      
    
      The
      appellant
      is
      entitled
      to
      its
      costs
      in
      the
      Divisional
      Court
      and
      of
      this
      appeal.
