      appealed
      from
      a
      reassessment

      summary
      of
      the
      allegations
      in
      the

      appeal,
      some
      of
      which
      are
      admitted
      in
      the
      replies

      not,
      is
      as
      follows:
      
      
      
      
    
      C.B.
      and
      I.A.C.
      Ltd.
      ("I.A.C.")
      amalgamated
      in
      1984
      and
      henceforth
      C.B.
      
      
      carried
      on,
      in
      addition
      to
      its
      banking
      business,
      the
      business
      of
      leasing
      property,
      
      
      using
      leasing
      assets
      which
      it
      acquired
      on
      its
      amalgamation
      with
      I.A.C.
      
      
      New
      leasing
      business
      was
      carried
      on
      through
      C.L.
      
      
      
      
    
      For
      reasons
      alleged
      in
      the
      notice
      of
      appeal
      which
      will
      no
      doubt
      be
      the
      
      
      subject
      of
      evidence
      at
      trial,
      C.B.
      decided
      to
      divest
      itself
      of
      its
      banking
      and
      
      
      leasing
      business
      and
      to
      wind
      up.
      It
      sold
      its
      banking
      business
      to
      Lloyds
      Bank
      of
      
      
      Canada,
      but
      not
      the
      leasing
      business
      or
      the
      shares
      of
      C.L.
      It
      entered
      into
      
      
      negotiations
      with
      Central
      Capital
      Corporation
      and
      an
      agreement
      was
      reached
      
      
      whereby
      Central
      Capital
      ("C.C.")
      would
      acquire
      the
      shares
      of
      C.L.
      on
      the
      
      
      understanding
      that
      C.B.'s
      leasing
      assets
      would
      be
      transferred
      to
      C.L.
      before
      the
      
      
      acquisition.
      
      
      
      
    
      C.B.
      transferred
      its
      leasing
      assets
      to
      C.L.
      on
      November
      1,
      1986.
      For
      reasons
      
      
      that
      may
      be
      relevant
      at
      trial
      but
      are
      not
      relevant
      in
      this
      motion,
      C.C.
      declined
      to
      
      
      proceed
      with
      the
      purchase
      of
      C.L.'s
      shares.
      Negotiations
      with
      C.C.
      were
      
      
      reopened
      and
      a
      restructured
      deal
      was
      struck.
      It
      was
      alleged
      in
      paragraph
      23
      of
      
      
      the
      notice
      of
      appeal
      that
      in
      accordance
      with
      the
      new
      agreement
      of
      December
      
      
      23,
      1986,
      C.L.
      and
      two
      subsidiaries
      of
      C.C.,
      693396
      Ontario
      Ltd.
      ("6933%")
      and
      
      
      Central
      Capital
      Management
      ("C.C.M.")
      formed
      a
      partnership
      on
      December
      
      
      24,
      1986,
      known
      as
      Central
      Capital
      Leasing.
      C.L.
      then
      transferred
      its
      leasing
      
      
      business
      to
      the
      partnership
      for
      a
      99
      per
      cent
      interest
      in
      the
      partnership.
      
      
      Paragraph
      28
      of
      each
      notice
      of
      appeal
      states
      that
      an
      election
      under
      subsection
      
      
      97(2)
      of
      the
      
        Income
       
        Tax
       
        Act
      
      was
      filed
      to
      effect
      a
      disposition
      by
      C.L.
      of
      the
      
      
      leasing
      assets
      at
      a
      deemed
      amount
      of
      $68,184,583.
      
      
      
      
    
      It
      is
      alleged
      that
      on
      December
      27,
      1986,
      C.L.
      wound
      up
      into
      C.B.
      and
      the
      
      
      partnership
      interest
      was
      transferred
      to
      C.B.
      In
      addition,
      it
      is
      alleged
      that
      C.B.
      
      
      purchased
      securities
      from
      C.C.
      for
      $130,000,000.
      This
      amount
      was
      transferred
      
      
      to
      the
      two
      subsidiaries,
      693396
      and
      C.C.M.,
      who
      paid
      it
      to
      C.B.
      as
      the
      purchase
      
      
      price
      of
      the
      interest
      in
      the
      partnership.
      
      
      
      
    
      The
      Minister
      of
      National
      Revenue,
      on
      assessing
      C.L.,
      took
      the
      position,
      
      
      
        inter
       
        alia,
      
      according
      to
      the
      "assumptions"
      pleaded
      in
      paragraph
      16
      of
      the
      C.L.
      
      
      reply,
      that
      C.L.
      amalgamated
      on
      December
      24,
      1986,
      with
      a
      numbered
      company
      
      
      and
      that
      the
      purpose
      of
      the
      transactions
      described
      was
      to
      transfer
      the
      
      
      leasing
      assets
      to
      subsidiaries
      of
      C.C.,
      that
      the
      transactions
      constituted
      the
      
      
      disposition
      by
      C.L.
      of
      its
      leasing
      assets
      and
      that
      the
      interposition
      of
      the
      
      
      amalgamated
      company
      and
      the
      partnership
      was
      a
      sham
      and
      that
      the
      appellant
      
      
      was
      not
      a
      member
      of
      the
      partnership
      because
      it
      did
      not
      acquire
      the
      partnership
      
      
      interest
      with
      the
      intention
      of
      carrying
      on
      business
      in
      common
      for
      profit
      
      
      but
      with
      a
      view
      to
      disposing
      of
      its
      assets
      for
      proceeds
      which
      represented
      the
      
      
      sale
      price
      of
      its
      assets.
      
      
      
      
    
      All
      of
      this
      has
      led
      to
      inconsistent
      assessments.
      The
      Minister
      assessed
      C.L.
      
      
      on
      recapture
      of
      about
      $83,000,000
      on
      the
      basis
      that
      the
      involvement
      of
      the
      
      
      partnership
      in
      the
      transaction
      was
      a
      sham.
      He
      assessed
      C.B.
      on
      the
      basis
      that
      
      
      the
      gain
      realized
      on
      the
      disposition
      of
      the
      partnership
      interest
      was
      a
      trading
      
      
      gain
      and
      not
      a
      capital
      gain.
      The
      Minister
      acknowledges
      that
      the
      two
      assessments
      
      
      are
      inconsistent
      and
      cannot
      both
      stand,
      but
      asserts
      that
      to
      protect
      the
      
      
      public
      revenues
      he
      is
      entitled
      to
      advance
      inconsistent
      and
      indeed
      mutually
      
      
      exclusive
      positions.
      The
      assessment
      against
      C.L.
      denies
      the
      validity
      of
      the
      
      
      partnership
      or
      the
      subsection
      97(2)
      rollover
      whereas
      the
      assessment
      against
      
      
      C.B.
      is
      necessarily
      premised

      10
      paragraphs
      of
      the
      notice
      of
      appeal
      that
      the
      
      
      respondent
      admits,
      including
      paragraph
      29.
      Ms.
      Boris,
      in
      her
      affidavit
      filed
      on
      
      
      the
      motion,
      states
      that
      she
      now
      does
      not
      know
      why
      she
      admitted
      paragraph
      29
      
      
      but
      she
      believed
      that
      it
      was
      inconsistent
      with
      the
      position
      that
      she
      thought
      she
      
      
      was
      advancing
      on
      behalf
      of
      the
      respondent.
      The
      admission
      of
      paragraph
      29
      of
      
      
      the
      C.B.
      notice
      of
      appeal
      is
      consistent
      with
      the
      respondent's
      position
      in
      that
      
      
      case,
      but
      it
      is
      inconsistent
      with
      the
      position
      advanced
      in
      paragraphs
      16(g),
      (h),
      
      
      
      
    
      (i)
      and
      (j)
      of
      the
      C.L.
      reply
      which
      asserts
      a
      sham
      transaction.
      
      
      
      
    
      I
      am
      satisfied,
      on
      the
      evidence
      before
      me
      on
      the
      motion,
      that
      the
      admission
      
      
      of
      paragraph
      29
      in
      the
      C.L.
      reply
      was
      inadvertent
      in
      the
      sense
      that
      the
      full
      
      
      implications
      that
      the
      admission
      would
      have
      on
      the
      inferences
      the
      Court
      could
      
      
      be
      invited
      to
      draw
      were
      not
      appreciated
      at
      the
      time
      the
      reply
      was
      filed.
      Ms.
      
      
      Boris
      was
      cross-examined
      at
      length
      on
      her
      affidavit
      and
      I
      was
      referred
      to
      no
      
      
      portion
      of
      her
      cross-examination
      that
      is
      inconsistent
      with
      that
      conclusion.
      
      
      
      
    
      The
      admission
      of
      paragraph
      29
      of
      the
      notice
      of
      appeal
      is
      also
      inconsistent
      
      
      with
      another
      group
      of
      amendments
      which
      the
      Crown
      wishes
      to
      make
      to
      the
      
      
      C.L.
      reply,
      specifically
      new
      paragraphs
      19
      to
      25.
      I
      shall
      not
      reproduce
      these
      
      
      paragraphs
      in
      full.
      They
      are
      in
      the
      material
      filed.
      New
      paragraph
      19
      states
      in
      
      
      part
      that
      the
      Attorney
      General
      submits
      that
      "the
      purported
      partnership
      agreement
      
      
      was
      legally
      ineffective
      to
      make
      the
      appellant
      a
      partner
      and
      the
      appellant
      
      
      never
      was
      such
      a
      partner".
      Paragraph
      19
      goes
      on
      to
      allege
      a
      legal
      impediment
      
      
      to
      the
      appellant's
      becoming

      174

        Act.
      
      
      
      Paragraph
      20
      alleges
      that
      the
      appellant
      did
      not
      in
      relation
      to
      the
      partnership
      
      
      carry
      on
      business
      in
      common
      with
      a
      view
      to
      profit.
      Paragraph
      21
      alleges
      that
      
      
      the
      partnership
      agreement
      was
      a
      sham
      and
      the
      appellant's
      purported
      membership
      
      
      in
      the
      partnership
      was
      a
      simulacrum.
      Paragraph
      22
      says
      roughly
      the
      same
      
      
      thing
      in
      relation
      to
      the
      subsection
      97(2)
      election.
      Paragraph
      25
      alleges
      that
      
      
      $130,071,985
      was
      part
      of

        It

        in

      I
      have

      best
      be

      54
      and
      132
      of
      the
      Tax
      Court
      Rules
      —
      General
      Procedure,
      read
      as
      
      
      follows:
      
      
      
      
    
        54.
        A
        pleading
        may
        be
        amended
        by
        the
        party
        filing
        it,
        at
        any
        time
        before
        the
        close
        
        
        of
        pleadings,
        and
        thereafter
        either
        on
        filing
        the
        consent
        of
        all
        other
        parties,
        or
        with
        
        
        leave
        of
        the
        Court,
        and
        the
        Court
        in
        granting
        leave
        may
        impose
        such
        terms
        as
        are
        
        
        just.
        
        
        
        
      
        132.
        A
        party
        may
        withdraw
        an
        admission
        made
        in
        response
        to
        a
        request
        to
        admit,
        a
        
        
        deemed
        admission
        or
        an
        admission
        in
        the
        party's
        pleading
        on
        consent
        or
        with
        
        
        leave
        of
        the
        Court.
        
        
        
        
      
      Subsection
      4(1)
      of
      those
      rules
      provides:
      
      
      
      
    
        4.(1)
        These
        rules
        shall
        be
        liberally
        construed
        to
        secure
        the
        just,
        most
        expeditious
        
        
        and
        least
        expensive
        determination
        of
        every
        proceeding
        on
        its
        merits.
        
        
        
        
      
      These
      provisions
      give
      the
      court
      a
      broad
      discretion
      to
      permit
      the
      withdrawal
      
      
      of
      admissions
      and
      the
      amendment
      of
      pleadings
      where
      it
      is
      in
      the
      interests
      of
      
      
      justice
      to
      do
      so.
      I
      was
      referred
      to
      a
      number
      of
      cases
      in
      the
      courts
      of
      British
      
      
      Columbia,
      Ontario
      and
      the
      Supreme
      Court
      of
      Canada.
      It
      would
      seem
      that
      
      
      there
      has
      been
      a
      relaxation
      of
      the
      rule
      that
      an
      admission
      may
      be
      withdrawn
      
      
      only
      if
      it
      is
      shown
      to
      be
      wrong.
      That
      rule
      was
      stated
      in
      
        Canada
       
        Permanent
      
        Mortgage
       
        Corp.
      
      v.
      
        The
       
        City
       
        of
       
        Toronto,
      
      [1951]
      O.R.
      726.
      The
      statement
      of
      the
      
      
      rule
      was
      criticized
      as
      being
      too
      wide
      by
      Cartwright,
      J.
      (as
      he
      then
      was)
      in
      
        Papp
      
        Estate
      
      v.
      
        M.N.R.,
      
      [1964]
      S.C.R.
      66,
      [1964]
      C.T.C.
      128,
      63
      D.T.C.
      1219,
      and
      a
      party
      
      
      was
      permitted
      to
      withdraw
      an
      admission
      made
      even
      though
      it
      had
      not
      been
      
      
      established
      that
      the
      fact
      admitted
      was
      untrue.
      
      
      
      
    
      Courts
      subsequently
      have
      essentially
      applied
      a
      more
      liberal
      test
      which
      
      
      permitted
      amendments
      or
      withdrawal
      of
      admissions
      where
      a
      triable
      issue
      of
      
      
      fact
      or
      law
      is
      thereby
      raised
      and
      where
      the
      amendment
      or
      withdrawal
      would
      
      
      not
      result
      in
      a
      prejudice
      to
      the
      opposing
      party
      that
      was
      not
      compensable
      in
      
      
      costs.
      Counsel
      for
      the
      appellant
      contended
      that
      no
      evidence
      had
      been
      adduced
      
      
      to
      show
      that
      the
      proposed
      amendments
      raised
      a
      triable
      issue.
      I
      think
      
      
      that
      this
      submission
      involves
      an
      unduly
      narrow
      reading
      of
      the
      cases.
      The
      
      
      triable
      issue
      of
      the
      nature
      and
      substance
      of
      the
      partnership
      transaction
      is
      
      
      clearly
      before
      the
      court
      and
      the
      admission
      of
      paragraph
      29
      of
      the
      notice
      of
      
      
      appeal
      is
      inconsistent
      with
      the
      other
      allegations
      in
      the
      reply,
      some
      of
      which
      
      
      were
      already
      pleaded
      and
      some
      of
      which
      are
      proposed
      to
      be
      added,
      without
      
      
      objection.
      New
      paragraphs
      23
      and
      24
      are
      simply
      a
      more
      elaborate
      articulation
      
      
      of
      the
      basic
      position
      taken
      by
      the
      Minister,
      the
      best
      evidence
      of
      which
      is
      the
      
      
      making
      of
      the
      assessment
      itself.
      In
      these
      circumstances
      there
      is
      no
      need
      for
      
      
      further
      evidence.
      
      
      
      
    
      It
      was
      also
      contended
      that
      the
      party
      moving
      for
      the
      amendment
      had
      an
      
      
      onus
      of
      showing
      no
      prejudice
      by
      the
      amendment
      to
      the
      party
      opposing.
      
      
      Counsel
      for
      the
      appellant
      did
      not
      suggest
      that
      there
      was
      any
      prejudice
      and
      I
      
      
      should
      have
      thought
      that
      if
      there
      were
      prejudice
      that
      was
      not
      compensable
      in
      
      
      costs
      it
      would
      be
      reasonable
      to
      expect
      the
      opposing
      party
      to
      adduce
      evidence
      
      
      to
      that
      effect.
      It
      is
      difficult
      in
      any
      event
      to
      see
      what
      significant
      prejudice
      the
      
      
      appellant
      has
      suffered
      apart
      from
      the
      delay
      in
      proceeding
      with
      the
      examination
      
      
      for
      discovery
      of
      an
      officer
      of
      the
      appellant
      and
      the
      loss
      of
      the
      tactical
      advantage
      
      
      of
      not
      having
      to
      prove
      an
      allegation
      that
      had
      been
      inadvertently
      admitted
      by
      
      
      the
      respondent.
      Either
      the
      allegation
      in
      paragraph
      29
      is
      true
      or
      it
      is
      not
      true.
      If
      it
      
      
      is
      true
      it
      should
      be
      readily
      provable
      in
      considerably
      less
      time
      than
      this
      motion
      
      
      has
      taken.
      If
      it
      is
      not
      true
      it
      should
      not
      have
      been
      admitted
      and
      the
      Court
      
      
      should
      not
      be
      required
      to
      base
      its
      decision
      on
      an
      erroneous
      factual
      premise.
      
      
      While
      I
      do
      not
      doubt
      the
      authority
      of
      the
      Attorney
      General
      of
      Canada
      to
      make
      
      
      admissions
      of
      fact
      in
      litigation
      to
      which
      the
      Crown
      is
      a
      party,
      it
      must
      be
      
      
      recognized
      that
      there
      is
      a
      public
      interest
      in
      income
      tax
      appeals
      and
      the
      Court
      
      
      should
      be
      in
      a
      position
      to
      decide
      cases
      on
      the
      basis
      of
      correct
      facts
      and
      
      
      properly
      defined
      issues
      (c.f.
      
        The
       
        Clarkson

      It
      would
      do
      no
      
      
      credit
      to
      our
      system
      of
      justice
      in
      Canada
      if
      the
      courts
      were
      restricted
      in
      their
      
      
      consideration
      of
      the
      merits
      of
      a
      case
      by
      an
      ill-considered
      admission
      that
      is
      
      
      inconsistent
      with
      another
      position
      that
      is
      being
      advanced,
      particularly
      where
      it
      
      
      is
      sought
      to
      withdraw
      such
      an
      admission
      at
      an
      early
      stage
      in
      the
      proceeding.
      
      
      This
      is
      equally
      true
      whether
      the
      party
      seeking
      to
      change
      its
      position
      is
      the
      
      
      taxpayer
      or
      the
      Crown.
      
      
      
      
    
      In
      the
      cases
      in
      the
      courts
      of
      Ontario
      and
      of
      British
      Columbia
      to
      which
      I
      was
      
      
      referred
      a
      number
      of
      tests
      have
      been
      developed
      —whether
      an
      admission
      was
      
      
      inadvertent,
      whether
      there
      is
      a
      triable
      issue
      raised
      by
      an
      amendment
      or
      the
      
      
      withdrawal
      of
      an
      admission
      and
      whether
      the
      other
      party
      would
      suffer
      a
      
      
      prejudice
      not
      compensable
      in
      costs.
      Although
      I
      find
      that
      these
      tests
      have
      been
      
      
      met
      I
      prefer
      to
      put
      the
      matter
      on
      a
      broader
      basis:
      whether
      it
      is
      more
      consonant
      
      
      with
      the
      interests
      of
      justice
      that
      the
      withdrawal
      or
      amendment
      be
      permitted
      or
      
      
      that
      it
      be
      denied.
      The
      tests
      mentioned
      in
      cases
      in
      other
      courts
      are
      of
      course
      
      
      helpful
      but
      other
      factors
      should
      also
      be
      emphasized,
      including
      the
      timeliness
      
      
      of
      the
      motion
      to
      amend
      or
      withdraw,
      the
      extent
      to
      which
      the
      proposed
      
      
      amendments
      would
      delay
      the
      expeditious
      trial
      of
      the
      matter,
      the
      extent
      to
      
      
      which
      a
      position
      taken
      originally
      by
      one
      party
      has
      led
      another
      party
      to
      follow
      a
      
      
      course
      of
      action
      in
      the
      litigation
      which
      it
      would
      be
      difficult
      or
      impossible
      to
      
      
      alter
      and
      whether
      the
      amendments
      sought
      will
      facilitate
      the
      Court's
      consideration
      
      
      of
      the
      true
      substance
      of
      the
      dispute
      on
      its
      merits.
      No
      single
      factor
      
      
      predominates
      nor
      is
      its
      presence
      or
      absence
      necessarily
      determinative.
      All
      
      
      must
      be
      assigned
      their
      proper
      weight
      in
      the
      context
      of
      the
      particular
      case.
      
      
      Ultimately
      it
      boils
      down
      to
      a
      consideration
      of
      simple
      fairness,
      common
      sense
      
      
      and
      the
      interest
      that
      the
      courts
      have
      that
      justice
      be
      done.
      
      
      
      
    
      All
      of
      these
      considerations
      lead
      me
      to
      conclude
      that
      the
      Crown's
      motion
      in
      
      
      the
      C.L.
      appeal
      should
      be
      granted.
      
      
      
      
    
        The
       
        amendment
       
        to
       
        the
      
      C.B.
      
        reply
      
      In
      the
      C.B.
      appeal
      the
      Crown
      seeks
      to
      delete
      paragraph
      40
      of
      its
      reply
      and
      
      
      substitute
      new
      paragraphs
      40,
      40A,
      40B,
      40C,
      40D,
      40E,
      40F
      and
      40G.
      The
      
      
      appellant
      opposes
      the
      addition
      of
      paragraphs
      40B,
      40C,
      40D
      and
      40E.
      It
      does
      
      
      not
      oppose
      any
      other
      amendments,
      including
      the
      extensive
      amendments
      to
      
      
      paragraph
      34
      which
      contains
      a
      statement
      of
      the
      so-called
      "assumptions"
      upon
      
      
      which
      the
      Minister
      allegedly
      acted
      in
      making
      the
      assessments.
      The
      amendments
      
      
      in
      issue
      have
      to
      do
      with
      the
      treatment
      upon
      the
      winding-up
      of
      Tri-Prairie
      
      
      Grain
      Ltd.
      ("Tri-Prairie")
      of
      certain
      non-capital
      losses
      alleged
      to
      have
      been
      
      
      incurred
      by
      it.
      The
      issues
      are
      complex
      and
      technical
      and
      arise
      in
      part
      out
      of
      the
      
      
      somewhat
      tangled
      interaction
      of
      sections
      80,
      88
      and
      111
      of
      the
      
        Income
       
        Tax
       
        Act.
      
      
      
      They
      include
      such
      questions
      as
      the
      magnitude
      of
      the
      non-capital
      loss
      of
      Tri-
      
      
      Prairie,
      the
      time
      that
      it
      was
      incurred,
      whether
      the
      loss
      was
      incurred
      by
      Tri-
      
      
      Prairie
      or
      by
      other
      persons,
      the
      effect
      on
      the
      losses
      under
      section
      80
      of
      an
      
      
      alleged
      settlement
      or
      extinguishment
      of
      debts
      owing
      to
      the
      appellant
      by
      Tri-
      
      
      Prairie,
      the
      timing
      of
      the
      alleged
      extinguishment,
      the
      timing
      of
      the
      alleged
      
      
      winding-up
      of
      Tri-Prairie,
      the
      effect
      of
      an
      alleged
      change
      of
      control
      of
      TriPrairie,
      
      
      the
      effect
      of
      an
      alleged
      change
      of
      year
      end
      of
      Tri-Prairie
      as
      well
      as
      the
      
      
      ownership
      of
      Tri-Prairie
      at
      the
      time
      of
      its
      winding-up.
      
      
      
      
    
      The
      opposition
      to
      the
      addition
      of
      paragraphs
      40B,
      40C,
      40D
      and
      40E
      is
      that
      
      
      they
      contain
      statements
      that
      are
      inconsistent
      with
      certain
      of
      the
      "assumptions"
      
      
      pleaded,
      particularly
      with
      respect
      to
      the
      time
      that
      Tri-
      Prairie
      began
      its
      winding-
      
      
      up,
      the
      fiscal
      period
      of
      Tri-Prairie
      and
      the
      date
      upon
      which
      the
      indebtedness
      of
      
      
      Tri-Prairie
      was
      extinguished.
      
      
      
      
    
      It
      is
      true
      that
      there
      are
      inconsistencies
      between
      the
      assumptions
      pleaded
      
      
      and
      the
      allegations
      in
      the
      paragraphs
      that
      the
      Minister
      now
      wishes
      to
      add.
      Had
      
      
      these
      paragraphs
      been
      included
      in
      the
      original
      reply
      those
      inconsistencies
      
      
      would
      not
      have
      justified
      striking
      the
      paragraphs.
      The
      respondent
      is
      not
      bound
      
      
      by
      the
      assumptions
      made
      on
      assessing.
      She
      is
      entitled,
      in
      support
      of
      the
      
      
      assessment,
      to
      allege
      new
      facts
      or
      facts
      that
      are
      inconsistent
      with
      those
      assumed
      
      
      on
      assessing,
      provided
      that
      she
      bears
      the
      onus
      of
      proving
      those
      facts.
      
      
      An
      assumption,
      in
      the
      sense
      in
      which
      the
      word
      has
      come
      to
      be
      used
      in
      income
      
      
      tax
      appeals,
      is
      not
      a
      binding
      admission.
      
      
      
      
    
      At
      this
      relatively
      early
      stage
      in
      this
      complex
      case
      I
      do
      not
      think
      it
      is
      
      
      appropriate
      that
      I
      should,
      in
      an
      interlocutory
      motion,
      seek
      to
      resolve
      the
      
      
      possible
      inconsistencies
      between
      the
      alternative
      positions
      taken
      by
      the
      Minister.
      
      
      Any
      attempt
      to
      reconcile
      them
      or
      to
      decide
      which
      the
      Minister
      is
      entitled
      
      
      to
      advance
      and
      which
      he
      is
      not
      would
      necessitate,
      in
      a
      sense,
      a
      determination
      
      
      of
      the
      merits
      of
      those
      positions.
      To
      do
      so
      would
      be
      to
      usurp
      the
      function
      of
      the
      
      
      judge
      who
      hears
      the
      case.
      To
      refuse
      to
      permit
      the
      addition
      of
      the
      paragraphs
      in
      
      
      question
      would
      be
      to
      restrict
      the
      ability
      of
      the
      court
      at
      trial
      to
      consider
      all
      
      
      aspects
      of
      the
      matter
      on
      its
      merits.
      The
      allegations
      in
      paragraphs
      40B,
      40C,
      40D
      
      
      and
      40E
      are
      integrally
      connected
      with
      the
      rest
      of
      the
      reply
      and
      are
      necessary
      to
      
      
      the
      court's
      understanding
      of
      the
      overall
      position
      advanced
      by
      the
      Crown.
      
      
      
      
    
      The
      respondent's
      application
      to
      amend
      the
      replies
      is
      granted.
      The
      respondent
      
      
      is
      at
      liberty
      to
      file
      amended
      replies
      in
      the
      form
      attached
      as
      appendix
      B
      to
      
      
      the
      notices
      of
      motion
      dated
      June
      16,
      1992.
      The
      appellants
      are
      entitled
      to
      their
      
      
      costs,
      if
      any,
      thrown
      away
      as
      the
      result
      of
      the
      postponement
      of
      the
      examination
