The
Chief
Justice
(ail
concurring):—This
is
an
appeal
from
a
judgment
of
the
Trial
Division
dismissing
an
appeal
from
a
judgment
of
the
Tax
Appeal
Board
that
dismissed
an
appeal
from
the
appellant’s
assessments
under
Part
I
of
the
Income
Tax
Act
for
its
1958,
1959,
1960
and
1961
taxation
years.
In
this
Court,
the
only
question
that
has
been
raised
by
the
appellant
is
whether
the
tax
fixed
by
each
of
the
aforesaid
assessments
was
excessive
because
it
was
based
on
a
computation
of
the
appellant’s
income
for
the
year
in
the
calculation
of
which
there
was
deducted
a
smaller
amount
than
that
to
which
the
appellant
was
entitled
under
subsection
83A(3)
of
the
Income
Tax
Act,
which
reads
in
part
as
follows:
83A(3)
A
corporation
whose
principal
business
is
(a)
production,
refining
or
marketing
of
petroleum,
petroleum
products
or
natural
gas,
or
exploring
or
drilling
for
petroleum
or
natural
gas,
or
(b)
mining
or
exploring
for
minerals,
may
deduct,
in
computing
its
income
under
this
Part
for
a
taxation
year,
the
lesser
of
(c)
the
aggregate
of
such
of
(i)
the
drilling
and
exploration
expenses,
including
all
general
geological
and
geophysical
expenses,
incurred
by
it
on
or
in
respect
of
exploring
or
drilling
for
petroleum
or
natural
gas
in
Canada,
and
(ii)
the
prospecting,
exploration
and
development
expenses
incurred
by
it
in
searching
for
minerals
in
Canada,
as
were
incurred
after
the
calendar
year
1952
and
before
April
11,
1962,
to
the
extent
that
they
were
not
deductible
in
computing
income
for
a
previous
taxation
year,
or
(d)
of
that
aggregate,
an
amount
equal
to
its
income
for
the
taxation
year
(i)
if
no
deduction
were
allowed
under
paragraph
(b)
of
subsection
(1)
of
section
11,
and
(ii)
if
no
deduction
were
allowed
under
this
section,
minus
the
deductions
allowed
for
the
year
by
subsections
(1),
(2),
(8a)
and
(8d)
of
this
section
and
by
section
28.
In
applying
this
provision,
a
question
arises
between
the
parties
concerning
the
determination
of
the
amount
that
has
to
be
calculated
under
paragraph
(c).
To
be
specific,
there
is
a
question
as
to
how
much
of
the
expenses
of
the
kind
described
in
subparagraph
(ii)
that
were
incurred
by
the
appellant
in
earlier
years
were
“deductible
in
computing
income
for
a
previous
year”
within
the
meaning
of
those
words
in
that
paragraph.
This
is
relevant,
as
a
reading
of
the
concluding
words
of
paragraph
(c)
shows,
because
the
expenses
incurred
by
the
appellant
in
previous
years
are
only
deductible
by
virtue
of
subsection
83A(3)
for
one
of
the
taxation
years
now
under
consideration
“to
the
extent
that
they
were
not
deductible
in
computing
income
for
a
previous
taxation
year”.
The
factual
background
to
the
dispute
is
that,
in
its
return
for
each
of
the
taxation
years
1955,
1956
and
1957,
the
appellant
claimed
deductions
under
subsection
83A(8a)
in
respect
of
expenses
incurred
by
its
parent
company.
It
is,
at
this
stage,
common
ground
that
those
expenses
were
not
legally
deductible
but,
at
the
assessment
stage,
the
assessors
appear
to
have
mistakenly
regarded
them
as
deductible
and,
in
consequence,
issued,
for
each
of
those
years,
what
is
commonly
called
a
“nil
assessment”,
which
document
is
more
accurately
described
as
a
notification
that
no
tax
is
payable.
It
is,
I
think,
common
ground
that,
if
the
expenses
incurred
by
the
parent
company
had
been
disallowed
for
the
1955,
1956
and
1957
taxation
years,
as
they
should
have
been,
the
amounts
now
in
issue
in
respect
of
the
1958,
1959,
1960
and
1961
taxation
years
would
have
been
“deductible”
under
section
83A(3)
in
respect
of
the
1955,
1956
and
1957
taxation
years
and,
in
that
event,
would
not
be
deductible
under
subsection
83A(3)
in
respect
of
the
1958,
1959,
1960
and
1961
taxation
years.
In
this
Court,
the
appellant
limited
his
argument
in
support
of
the
appeal
to
a
single
point,
which
point
was
not
taken
in
the
Trial
Division.
The
point
is
that
the
parent
company’s
expenditures
were
in
fact
“allowed”
by
the
assessments
in
the
earlier
years
and
that
that
factual
“allowance
was
sufficient,
having
regard
to
the
concluding
words
of
paragraph
(d)
of
subsection
83A(3),
to
make
the
appellant’s
own
disbursements
(for
at
least
the
parts
of
them
that
are
now
in
dispute)
not
“deductible”
in
computing
income
for
those
earlier
years
so
that
they
are
deductible
under
subsection
83A(3)
in
the
computation
of
the
appellant’s
income
for
the
taxation
years
now
under
consideration.
This
point
in
my
view
fails.
The
words
upon
which
the
appellant
relies
are
the
deductions
allowed
.
.
.
by
subsections
(1),
(2),
(8a)
and
(8d)
.
.
.
These
words
do
not,
in
my
view,
refer
to
amounts
that
are
in
fact
allowed
by
the
Minister
because
he
rightly
or
wrongly
thinks
that
they
fall
under
subsection
(1),
(2),
(83)
or
(8d).
They
refer
to
amounts
the
deduction
of
which
is
permitted
by
one
or
other
of
those
subsections
rightly
understood.
It
is
simply
another
way
of
saying
“the
amounts
that
are
deductible
by
virtue
of
subsections
(1),
(2),
(8a)
and
(8d).”
As
that
was
the
only
point
relied
on
by
the
appellant
and
as,
in
my
view,
it
fails,
it
follows
that
I
am
of
opinion
that
the
appeal
should
be
dismissed
with
costs.
