Thurlow,
       
        J:—In
      
      my
      view
      the
      second,
      third
      and
      fourth
      points
      put
      
      
      forward
      by
      counsel
      for
      the
      respondents
      as
      justifying
      leave
      to
      appeal
      
      
      raise
      questions
      that
      are
      fairly
      arguable.
      I
      am
      not
      persuaded
      that
      the
      
      
      same
      can
      be
      said
      of
      the
      first
      or
      the
      fifth
      points
      so
      put
      forward.
      
      
      
      
    
      To
      say
      that
      there
      are
      three
      arguable
      points
      does
      not,
      however,
      resolve
      
      
      the
      problem
      whether
      the
      question
      involved
      in
      the
      case
      is
      one
      which
      
      
      ought
      to
      be
      submitted
      to
      the
      Supreme
      Court
      for
      decision.
      I
      do
      not
      
      
      think
      it
      was
      intended
      tnat
      leave
      to
      appeal
      should
      be
      granted
      either
      as
      
      
      a
      matter
      of
      course
      or
      simply
      because
      a
      question
      is
      interesting
      or
      difficult
      
      
      or
      arguable
      or
      because
      the
      decision
      will
      serve
      as
      a
      guide
      to
      the
      
      
      parties
      and
      to
      others
      for
      the
      future.
      Rarely
      would
      there
      be
      a
      case
      
      
      involving
      a
      point
      of
      taxation
      law
      that
      would
      not
      qualify
      for
      such
      
      
      reasons.
      
      
      
      
    
      On
      the
      other
      hand
      there
      are
      cases
      which
      raise
      an
      issue
      or
      question
      
      
      so
      fundamental
      that
      it
      is
      immediately
      apparent
      that
      the
      question
      is
      
      
      one
      that
      ought
      to
      be
      determined
      by
      the
      Supreme
      Court.
      As
      examples
      
      
      one
      can
      think
      of
      important
      constitutional
      questions
      and
      serious
      questions
      
      
      arising
      on
      the
      Canadian
      Bill
      of
      Rights.
      To
      my
      mind
      the
      case
      of
      
      
      
        Lavell
      
      v
      
        Attorney
       
        General
       
        of
       
        Canada,
      
      [1971]
      FC
      347,
      in
      which
      leave
      
      
      was
      granted
      by
      this
      Court,
      fell
      into
      that
      category.
      
      
      
      
    
      There
      are
      undoubtedly
      other
      types
      of
      cases
      as
      well
      which
      will
      
      
      meet
      the
      test
      but
      save
      when
      it
      is
      clear
      that
      a
      case
      is
      important
      enough
      
      
      to
      warrant
      an
      affirmative
      answer
      to
      the
      question
      posed
      by
      subsection
      
      
      31(2)
      of
      the
      
        Federal
       
        Court
       
        Act
      
      the
      proper
      course
      for
      this
      Court
      is,
      I
      
      
      think,
      to
      decline
      to
      grant
      leave
      and
      thus
      leave
      it
      to
      the
      Supreme
      Court
      
      
      to
      determine
      in
      which
      of
      such
      cases
      leave
      to
      appeal
      should
      be
      granted.
      
      
      
      
    
      So
      approaching
      the
      present
      case
      I
      reach
      the
      conclusion
      that
      leave
      
      
      to
      appeal
      should
      be
      refused.
      
      
      
      
    
      The
      judgment
      in
      my
      view
      involves
      nothing
      more
      striking
      or
      fundamental
      
      
      than
      the
      interpretation
      of
      particular
      provisions
      of
      the
      
        Antidumping
      
        Act
      
      and
      the
      
        Customs
       
        Act,
      
      dealing,
      in
      each
      case,
      with
      how
      
      
      imported
      goods
      are
      to
      be
      valued
      when
      other
      statutory
      provisions
      for
      
      
      their
      valuation
      fail.
      The
      judgment
      is
      of
      some
      direct
      or
      indirect
      importance
      
      
      to
      the
      respondents
      and
      is
      no
      doubt
      of
      some
      general
      interest
      
      
      to
      foreign
      exporters
      and
      domestic
      importers
      as
      well
      as
      to
      persons
      
      
      interested
      in
      tax
      jurisprudence.
      In
      it,
      there
      are,
      as
      I
      have
      said,
      several
      
      
      arguable
      points,
      One
      of
      the
      enactments,
      the
      
        Anti-dumping
       
        Act,
      
      is
      
      
      comparatively
      new
      and
      there
      has
      not
      been
      occasion.
      for
      it
      or
      for
      the
      
      
      somewhat
      older
      provision
      of
      the
      
        Customs
       
        Act
      
      to
      be
      passed
      upon
      by
      
      
      the
      Supreme
      Court.
      Notwithstanding
      these
      features
      of
      the
      matter,
      however,
      
      
      the
      interpretation
      to
      be
      put
      upon
      these
      provisions
      is
      not,
      as
      I
      
      
      see
      it,
      a
      question
      of
      such
      general
      or
      fundamental
      importance
      or
      interest
      
      
      that
      this
      Court
      should
      regard
      it
      as
      one
      that
      “ought
      to
      be
      submitted
      
      
      to
      the
      Supreme
      Court
      for
      decision”,
      particularly
      since
      it
      is
      open
      
      
      to
      that
      Court,
      notwithstanding
      the
      denial
      of
      leave
      by
      this
      Court,
      to
      
      
      give
      leave
      if
      it
      sees
      fit
      to
      do
      so,
      whether
      it
      considers
      the
      question
      
      
      raised
      to
      meet
      the
      test
      of
      subsection
      31(2)
      of
      the
      
        Federal
       
        Court
       
        Act
      
      or
      
      
      not.
      
      
      
      
    
      I,
      therefore,
      concur
      in
      the
      disposition
      of
      the
      application
      that
      has
      
      
      been
      proposed
      by
      the
      Chief
      Justice.
