THORSON,
P.:—This
is
an
appeal
from
the
decision
of
the
Income
Tax
Appeal
Board
(1951),
5
Tax
A.B.C.
45,
dated
September
6,
1951,
allowing
the
respondent’s
appeal
from
its
income
tax
assessment
for
its
taxation
year
ending
January
8,
1947,
on
the
ground
that
the
Minister
had
not
properly
exercised
his
discretion
under
Section
6(1)
(n)
of
the
Income
War
Tax
Act,
R.S.C.
1927,
c.
97.
The
appeal
relates
to
the
nature
and
extent
of
the
discretion
vested
in
the
Minister
to
allow
deductions
in
respect
of
depreciation
from
what
would
otherwise
be
taxable
income.
So
far
as
relevant
to
the
appeal
Section
6(1)
(n)
reads
as
follows:
“6.
In
computing
the
amount
of
the
profits
or
gains
to
be
assessed,
a
deduction
shall
not
be
allowed
in
respect
of
(n)
depreciation,
except
such
amount
as
the
Minister
in
his
discretion
shall
allow,
including
Provided,
however,
that
the
Minister
shall
not
allow
a
deduction
in
respect
of
depreciation
of
assets
owned
by
an
incorporated
taxpayer
from
the
income
of
the
said
taxpayer
if
he
is
satisfied
that
the
said
taxpayer
directly
or
indirectly
had
or
has
a
controlling
interest
in
a
company
or
companies
previously
the
owner
or
owners
of
the
said
assets
or
that
the
said
previous
owner
(which
term
shall
include
a
series
of
owners)
directly
or
indirectly
had
or
has
a
controlling
interest
in
the
said
taxpayer
or
that
the
said
taxpayer
and
the
previous
owner
were
or
are
directly
or
indirectly
subject
to
the
same
controlling
interest
and
that
the
aggregate
amount
of
deductions
which
have
been
allowed
to
the
said
taxpayer
and/or
the
said
previous
owner
in
respect
of
the
depreciation
of
such
assets
is
equal
to
or
greater
than
the
cost
of
the
said
assets
to
the
said
previous
owner
or
to
the
first
of
the
previous
owners
where
more
than
one;’’
The
facts
are
not
in
dispute.
By
an
agreement,
dated
August
1,
1946,
the
respondent
purchased
from
R.
H.
Williams
&
Sons
Limited
certain
lands
and
buildings
in
Regina
for
$850,000,
of
which
$506,000
was
for
the
buildings.
The
cost
of
these
buildings
to
R.
H.
Williams
&
Sons
Limited
had
been
$432,341.42
and
the
aggregate
amount
of
deductions
which
had
been
allowed
to
it
in
respect
of
their
depreciation
was
less
than
such
cost.
It
was
also
admitted
that
on
January
8,
1947,
the
respondent
had
a
controlling
interest
in
R.
H.
Williams
&
Sons
Limited
and,
on
the
hearing,
counsel
for
the
respondent
admitted
further,
but
only
for
the
purposes
of
this
appeal,
that
it
had
such
a
controlling
interest
at
all
material
times.
In
its
income
and
excess
profits
tax
return,
dated
July
8,
1947,
for
the
taxation
year
under
review
the
respondent
claimed
a
deduction
of
$5,452
in
respect
of
the
depreciation
of
the
buildings
which
it
had
purchased
from
R.
H.
Williams
&
Sons
Limited
but
the
Minister
in
his
assessment
allowed
a
deduction
of
only
$4,936.05,
basing
his
allowance
on
the
cost
of
the
buildings
to
R.
H.
Williams
&
Sons
Limited,
and
added
the
difference
back
to
the
amount
of
taxable
income
reported
by
the
respondent
in
its
return.
The
respondent
objected
to
the
assessment
and
appealed
against
it
to
the
Income
Tax
Appeal
Board.
The
appeal
was
heard
before
Mr.
W.
S.
Fisher,
Q.C.
He
followed
the
decision
of
the
Board
in
Stovel
Press
Limited
v.
Minister
of
National
Revenue
(1950),
4
Tax
A.B.C.
359,
and
allowed
the
appeal
for
the
reasons
given
in
that
case,
the
particular
reason
being
that
the
Minister,
in
basing
his
allowance
of
deduction
in
respect
of
depreciation
on
the
cost
of
the
buildings
to
R.
H.
Williams
&
Sons
Limited,
their
former
owner,
instead
of
on
their
cost
to
the
respondent,
their
present
owner,
had
not
properly
exercised
his
discretion
under
Section
6(1)
(11)
of
the
Income
War
Tax
Act
and
referred
the
assessment
back
to
the
Minister
for
reconsideration
and
reassessment
by
allowing
depreciation
based
on
the
cost
of
the
buildings
to
the
respondent.
From
this
decision
the
Minister
appeals
to
this
Court.
Before
I
deal
with
the
issue
in
the
appeal
I
must
comment
on
a
preliminary
question
on
which
I
requested
argument
by
counsel,
namely,
whether
the
following
statement
in
Goldman
v.
Minister
of
National
Revenue,
[1951]
Ex.
C.R.
274
at
282;
[1951]
C.T.C.
241
at
248,
is
correct:
“On
the
other
hand,
where
the
Minister
is
the
appellant
from
the
decision
of
the
Income
Tax
Appeal
Board
it
cannot
be
said
that
the
appeal
to
this
Court
is
an
appeal
from
the
assessment.
There
is
this
further
difference,
namely,
that
while
the
issue
in
the
appeal
is
the
correctness
of
the
assessment,
it
is
for
the
Minister
to
establish
its
correctness
in
fact
and
in
law.
The
Board
has
power
under
Section
83
of
the
Income
Tax
Act
to
vacate
or
vary
the
assessment
or
refer
it
back
to
the
Minister
for
reconsideration
and
reassessment.
It
is
to
be
assumed
that
the
Minister’s
appeal
is
from
a
decision
by
which
the
Board
has
exercised
one
of
these
powers.
Consequently,
the
assessment
has
been
found
erroneous
by
a
court
of
record
and
the
Minister
does
not
come
to
this
Court
with
any
presumption
of
its
validity
in
its
favour.
Indeed,
the
reverse
is
true.
Thus,
subject
to
the
same
comments
on
the
use
of
the
term
onus
as
those
made
previously,
the
onus
is
on
the
Minister
to
establish
the
correctness
of
the
assessment.
Likewise
it
is
the
Minister
who
should
be
called
upon
to
begin.”
The
statement
is
obiter
and
affords
another
illustration
of
the
danger
involved
in
such
a
statement
in
matters
that
have
not
been
fully
argued.
On
further
consideration,
I
have
come
to
the
conclusion
that
the
statement
is
erroneous
in
several
respects
and
ought
to
be
corrected.
The
basic
error
lies
in
failure
to
appreciate
the
effect
of
the
fact
that
the
hearing
of
an
appeal
from
a
decision
of
the
Income
Tax
Appeal
Board
to
this
Court
is
a
trial
de
novo
of
the
issues
of
fact
and
law
that
are
involved.
There
cannot,
I
think,
be
any
doubt
that
this
is
so
where
the
appeal
is
by
the
taxpayer.
It
must
equally
be
so
when
the
Minister
is
the
appellant.
In
either
event
the
hearing
in
this
Court
must
proceed
without
regard
to
the
case
made
before
the
Board
or
the
Board’s
decision.
Consequently,
where
the
Minister
appeals
from
the
decision
of
the
Board
allowing
an
appeal
from
the
assessment
the
fact
that
the
Board
found
the
assessment
to
be
erroneous
must
be
disregarded.
To
do
otherwise
would
be
tantamount
to
giving
effect
to
the
Board’s
decision
which
would
be
inconsistent
with
the
view
that
the
hearing
of
the
appeal
from
it
is
a
trial
de
novo.
Consequently,
it
was
incorrect
to
say
that
because
the
Board
found
the
assessment
erroneous
the
Minister
does
not
come
to
this
Court
with
any
presumption
of
its
validity
in
his
favour
and
that
the
onus
is
on
him
to
establish
its
correctness.
On
the
contrary,
the
true
position
is
that
on
an
appeal
to
this
Court
from
a
decision
of
the
Income
Tax
Appeal
Board,
whether
the
taxpayer
or
the
Minister
is
the
appellant,
the
assessment
under
consideration
carries
with
it
a
presumption
of
its
validity
until
the
taxpayer
establishes
that
it
is
incorrect
either
in
fact
or
in
law.
Thus,
the
onus
of
proving
that
it
is
incorrect
is
on
the
taxpayer,
notwithstanding
the
fact
that
the
Income
Tax
Appeal
Board
may
have
allowed
an
appeal
from
it.
It
follows,
under
the
circumstances,
that
while
the
Minister,
being
the
appellant,
may
be
called
upon
to
begin
he
may
rest
on
the
assessment
so
far
as
the
facts
are
concerned
without
adducing
any
evidence.
The
onus
of
proving
the
assessment
to
be
erroneous
in
fact
is
on
the
taxpayer.
I
now
come
back
to
the
issue
in
this
appeal.
There
are,
in
my
judgment,
several
reasons
for
allowing
it.
In
the
first
place,
it
was
not
within
the
competence
of
the
Board
when
it
referred
the
assessment
back
to
the
Minister
for
reconsideration
and
reassessment
to
direct
him
to
allow
depreciation
based
on
the
cost
of
the
buildings
to
the
respondent.
This
was
an
arrogation
by
it
of
a
decision
that
only
the
Minister
could
make.
It
was
for
him
in
the
exercise
of
his
discretion,
and
not
for
the
Board,
to
determine
not
only
the
rate
of
deduction,
if
any,
that
should
be
allowed
but
also
the
amount,
w
hether
of
cost
or
of
value,
to
which
such
rate
should
be
applied.
On
this
ground
alone
the
appeal
from
the
decision
a@
quo
must
be
allowed
to
the
extent
of
varying
the
terms
of
the
reference
back
to
the
Minister
if
any
reference
is
required.
But
there
is
a
stronger
reason
for
allowing
the
appeal.
Counsel
for
the
respondent
submitted
that
the
Minister
based
his
depreciation
allowance
on
the
cost
of
the
buildings
to
their
former
owner
because
he
considered
that
the
proviso
in
Section
6(1)(n)
was
applicable,
that
he
was
mistaken
in
this
view
since
it
was
not
applicable
by
reason
of
the
fact
that
the
aggregate
amount
of
the
deductions
which
had
been
allowed
in
respect
of
their
depreciation
was
not
equal
to
their
cost
to
the
former
owner,
that
in
considering
the
proviso
applicable
when
it
was
not
he
had
taken
an
irrelevant
matter
into
account
and
had
not
acted
on
proper
principles
and
that
under
the
authority
of
the
decision
in
Pioneer
Laundry
and
Dry
Cleaners
Limited
v.
Minister
of
National
Revenue,
[1940]
A.C.
127
;
[1938-39]
C.T.C.
411,
the
assessment
appealed
against
must
be
referred
back
to
the
Minister.
A
similar
submission
had
found
favour
with
the
Income
Tax
Appeal
Board
which
gave
effect
to
it.
There
Mr.
Fisher,
following
the
earlier
decision
by
the
Board
in
the
Stovel
Press
Limited
case
(supra),
considered
that
the
Pioneer
Laundry
case
(supra)
supported
his
decision.
I
am
unable
to
agree.
Under
the
circumstances,
it
is
important
to
set
out
the
facts
of
the
Pioneer
Laundry
case
(supra)
in
their
relation
to
the
law
that
was
then
in
force
and
then
analyse
what
it
really
decided.
The
facts
may
be
summarized
briefly.
The
appellant
company
in
that
case
had
acquired
certain
machinery
and
equipment
from
Home
Service
Company
Limited
at
a
price
fixed
by
an
independent
appraisal.
The
latter
company
had
acquired
all
the
assets
of
seven
companies
including
the
original
Pioneer
Laundry
and
Dry
Cleaners
Limited
which
had
gone
into
voluntary
liquidation.
These
assets
included
the
machinery
and
equipment
in
question
which
had
previously
belonged
to
the
original
Pioneer
Laundry
and
Dry
Cleaners
Limited.
While
they
were
in
this
ownership
they
had
been
fully
written
off
by
depreciation.
Moreover,
it
was
also
established
that
the
appellant
company
was
in
fact
controlled
by
the
same
shareholders
who
formerly
controlled
the
original
company.
At
this
time
the
provisions
of
the
Act
relating
to
the
allowance
of
deductions
in
respect
of
depreciation
were
contained
in
Sections
5
and
6.
Section
5(a)
read
as
follows:
‘‘o.
'Income’
as
hereinbefore
defined
shall
for
the
purposes
of
this
Act
be
subject
to
the
following
exemptions
and
deductions
:—
(a)
Such
reasonable
amount
as
the
Minister,
in
his
discretion,
may
allow
for
depreciation,
.
.
.’’
And
Section
6(1)
(b)
provided:
"6.
In
computing
the
amount
of
the
profits
or
gains
to
be
assessed,
a
deduction
shall
not
be
allowed
in
respect
of
(b)
any
outlay,
loss
or
replacement
of
capital
or
any
payment
on
account
of
capital
or
any
depreciation,
depletion
or
obsolescence,
except
as
otherwise
provided
in
this
Act;
...”
In
its
income
tax
return
for
its
taxation
year
ending
March
31,
1933,
the
appellant
company
claimed
deductions
in
respect
of
the
depreciation
of
the
machinery
and
equipment
but
the
Min-
ister,
through
the
Commissioner
of
Income
Tax,
disallowed
the
deductions
on
the
grounds,
put
briefly,
that
the
machinery
and
equipment
had
already
been
fully
depreciated
and
there
had
really
been
no
change
of
ownership
of
them
and
on
the
assessment
the
Minister
added
the
amount
of
the
deductions
back
to
the
amount
of
taxable
income
reported
by
the
appellant
company
in
its
return.
From
this
assessment
the
appellant
company
appealed
first
to
the
Minister
and
then
to
this
Court,
which
dismissed
its
appeal.
An
appeal
to
the
Supreme
Court
of
Canada
was
also
dismissed,
[1939]
S.C.R.
1;
[1988-39]
C.T.C.
401,
by
a
majority
of
the
Court,
but
its
decision
was
reversed
by
the
Judicial
Committee
of
the
Privy
Council.
Lord
Thanker-
ton,
who
delivered
its
judgment,
held
that
under
Section
5(1)
(a)
the
taxpayer
had
a
statutory
right
to
an
allowance
in
respect
of
depreciation
during
the
accounting
year
in
which
the
assessment
in
dispute
was
based
and
that
the
Minister
had
a
duty
to
fix
a
reasonable
amount
in
respect
of
that
allowance.
And
in
that
respect
he
adopted
the
statement
of
Davis,
J.,
in
the
Supreme
Court
of
Canada,
at
page
5
:
“The
appellant
was
entitled
to
an
exemption
or
deduction
in
‘such
reasonable
amount
as
the
Minister,
in
his
discretion,
may
allow
for
depreciation.’
That
involved,
in
my
opinion,
an
administrative
duty
of
quasi-judicial
character—a
discretion
to
be
exercised
on
proper
legal
principles.’’
Lord
Thankerton
held
further,
in
effect,
that
the
Minister
could
not
look
behind
the
facade
of
the
transaction
by
which
the
machinery
and
equipment
had
been
acquired
with
a
view
to
determining
whether
there
was
any
real
change
in
their
ownership.
As
he
put
it,
the
Minister
was
not
entitled
to
disregard
the
separate
legal
existence
of
the
appellant
company
and
to
inquire
as
to
who
its
shareholders
were
and
its
relation
to
its
predecessors.
The
taxpayer
was
the
company
and
not
its
shareholders.
Thus
he
found
two
errors
on
the
part
of
the
Commissioner
of
Income
Tax,
one
being
that
he
had
failed
to
appreciate
that
the
appellant
was
not
the
same
taxpayer
as
the
shareholders
but
had
a
separate
legal
existence,
and
the
other
that
the
taxpayer
had
a
statutory
right
to
a
reasonable
depreciation
allowance
and
that
it
was
not
within
the
power
of
the
Commissioner
to
refuse
it.
For
these
reasons
Lord
Thankerton
held
that
the
Minister
had
not
exercised
his
discretion
and
referred
the
assessment
back
to
the
Minister
for
exercise
of
it.
The
decision
of
the
Judicial
Committee
was
given
on
October
13,
1939,
and
as
soon
as
it
was
possible
for
Parliament
to
do
so
it
amended
the
law.
By
Section
10
of
chapter
34
of
the
Statutes
of
1940
paragraph
(a)
of
Section
5
of
the
Act
was
repealed
and
by
Section
16
of
the
same
amending
Act
paragraph
(n)
was
added
to
subsection
(1)
of
Section
6
so
that
it
read
as
follows:
‘“6.
In
computing
the
amount
of
the
profits
or
gains
to
be
assessed,
a
deduction
shall
not
be
allowed
in
respect
of
(n)
depreciation,
except
such
amount
as
the
Minister
in
his
discretion
may
allow,
including
such
extra
depreciation
as
the
Minister
in
his
discretion
may
allow
in
the
case
of
plant
and
equipment
built
or
acquired
to
fulfil
orders
for
war
purposes;”
The
amendments
were
assented
to
on
August
7,
1940,
and
made
applicable
to
the
1940
taxation
period
and
fiscal
periods
ending
therein
and
to
all
subsequent
periods.
The
proviso
to
Section
6(1)
(n)
came
later.
It
was
enacted
by
Section
7
of
chapter
14
of
the
Statutes
of
1943,
assented
to
on
May
20,
1943,
and
made
applicable
on
passing.
It
is
plain
that
after
these
changes
there
was
a
fundamental
change
in
the
law
from
that
which
obtained
at
the
time
of
the
Pioneer
Laundry
case
(supra).
In
the
first
place,
the
statutory
right
which
the
former
Section
5(1)
(a)
gave
to
every
taxpayer
to
have
a
reasonable
allowance
for
depreciation
has
been
taken
from
him.
Now
he
has
no
statutory
right
to
any
deduction
in
respect
of
depreciation
except
that
which
the
Minister
in
his
discretion
may
allow
to
him.
And,
secondly,
the
Minister,
far
from
being
forbidden
to
look
behind
the
facade
of
the
transaction
by
which
the
assets
were
required,
is
specifically
required
to
do
so
in
order
to
determine
whether
there
was
a
controlling
interest
between
the
owner
of
the
assets
and
their
former
owner.
Thus
it
seems
clear
that
if
the
present
law
had
been
in
force
at
the
time
the
Pioneer
Laundry
case
(supra)
was
before
the
Courts
it
would
not
have
been
possible
to
take
a
valid
objection
to
the
action
of
the
Commissioner
of
Income
Tax
for
it
would
clearly
have
been
permissible
and
proper.
Moreover,
it
seems
apparent
that
the
change
in
the
law
was
deliberately
made
to
render
the
decision
in
the
Pioneer
Laundry
case
(supra)
inapplicable
in
the
future
in
the
case
of
circumstances
similar
to
those
that
then
existed
and
to
enable
the
Minister,
in
such
circumstances,
to
do
exactly
what
the
Judicial
Committee
of
the
Privy
Council
had
said
he
could
not
do
under
the
law
then
in
force.
By
this
change
in
the
law
Parliament
cured
by
legislation
a
defect
which
the
Commissioner
had
unsuccessfully
tried
to
overcome
by
administrative
action.
Thus
the
situation
now
under
consideration
is
very
different
from
that
which
Lord
Thankerton
found
in
the
Pioneer
Laundry
case
(supra).
The
errors
which
he
attributed
to
the
Commis-
sioner
of
Income
Tax
in
that
case
do
not
exist
here.
Here
there
is
no
denial
by
the
Minister
of
a
statutory
right
to
a
deduction
in
respect
of
depreciation
as
there
was
held
to
be
in
that
case.
Nor
has
there
been
any
failure
on
the
part
of
the
Minister
to
recognize
the
separate
legal
existence
of
the
two
companies,
the
former
and
the
present
owner
of
the
buildings
under
consideration.
Indeed,
in
my
opinion,
the
decision
in
the
Pioneer
Laundry
case
(supra)
has
no
applicability
jn
the
present
case.
In
support
of
his
submission
that
the
Minister,
in
basing
his
allowance
of
a
deduction
in
respect
of
the
depreciation
of
the
buildings
on
their
cost
to
the
previous
owner,
had
not
exercised
his
discretion
on
proper
principles
counsel
for
the
respondent
relied
strongly
on
a
letter
written
on
behalf
of
the
Director
General
of
the
Corporation
Assessments
Branch
of
the
Taxation
Division
of
the
Department
of
National
Revenue
to
the
respondent,
dated
April
29,
1950,
in
which
the
following
statement
relating
to
depreciation
in
respect
of
the
buildings
appears
:
“The
question
has
received
careful
consideration
and
it
has
been
concluded
that
the
first
proviso
to
section
6(1)(n)
of
the
Income
War
Tax
Act
is
applicable.
Therefore,
the
depreciation
allowances
will
be
based
on
depreciation
cost
in
the
hands
of
the
vendor
corporation
as
indicated
to
you
by
the
Toronto
Office
of
this
Division.
Your
attention
is
directed
in
particular
to
the
words
‘had
or
has
a
controlling
interest’.
Although
Simpson’s
Limited
did
not
necessarily
have
a
controlling
interest
in
the
vendor
corporation
at
the
time
the
buildings
were
purchased,
it
had
a
controlling
interest
in
1947
and
1948
and
the
use
of
the
word
‘has’
in
the
quotation
given
above
makes
the
proviso
effective.’’
It
was
argued
on
the
strength
of
this
letter
that
the
Minister
had
concluded
that
the
proviso
was
applicable
and
that
since
it
was
not
applicable
in
view
of
the
fact
that
the
aggregate
amount
of
the
deductions
which
had
been
allowed
in
respect
of
depreciation
of
the
buildings
was
less
than
their
cost
to
their
former
owner
the
proviso
was
irrelevant
and
that
the
Minister
in
taking
an
irrelevant
matter
into
account
had
not
acted
on
proper
principles.
In
my
opinion,
there
is
no
substance
in
this
submission.
In
the
first
place,
it
is
plain
that
the
language
of
the
letter
is
not
as
precise
as
it
might
have
been.
It
is
obvious,
of
course,
that
the
facts
of
this
case
do
not
bring
it
within
the
operation
of
the
proviso.
Its
prohibition
against
the
allowance
of
any
further
deduction
in
respect
of
depreciation
cannot
take
effect
until
the
Minister
is
satisfied
that
two
conditions
exist,
firstly,
that
there
was
a
direct
or
indirect
controlling
interest
within
the
meaning
of
the
proviso
and,
secondly,
that
the
aggregate
amount
of
the
deductions
in
respect
of
depreciation
which
have
been
allowed
is
equal
to
or
greater
than
the
cost
of
the
assets
to
the
former
owner
or
owners.
It
is
only
when
the
Minister
is
satisfied
that
both
of
these
conditions
exist
that
the
proviso
applies
in
the
sense
that
it
comes
into
operative
effect
which
means,
of
course,
that
the
Minister
has
no
discretion
to
allow
any
further
deduction.
That
being
so,
it
is
plain
that
when
the
writer
of
the
letter
said
that
it
had
been
concluded
that
the
proviso
was
applicable
he
could
not
have
meant
literally
what
his
letter
said,
for
if
it
had
been
so
concluded
the
Minister
would
not
have
had
any
right
to
allow
any
further
deduction.
Since
the
writer
of
the
letter
could
not
have
meant
what
his
words
said
the
true
meaning
of
his
letter
must
be
sought.
If
it
is
read
as
a
whole
it
becomes
reasonably
clear
that
all
that
the
writer
meant
to
tell
the
respondent
was
that
since
there
was
a
controlling
interest
of
the
kind
mentioned
in
the
proviso
the
proviso
was
“applicable”
or
‘‘effective’’
in
the
sense
that
the
buildings
had
been
acquired
by
the
new
owner
under
circumstances
of
controlling
interest
that
brought
them
within
the
purview
of
the
policy
embodied
in
the
proviso
and
that,
therefore,
the
depreciation
allowance
would
be
based
on
the
cost
of
the
buildings
to
their
former
owner.
I
must
say
that
I
see
nothing
irrelevant
or
improper
in
this
statement
or
the
action
that
was
taken.
It
seems
to
me
that
after
the
former
Section
5(1)
(a)
of
the
Act
was
repealed
and
the
opening
words
of
Section
6(1)
(n)
were
enacted
it
would
have
been
competent
for
the
Minister,
even
if
there
had
not
been
any
proviso,
to
do
exactly
what
he
did.
In
cases
where
he
found
that
assets
had
been
acquired
under
circumstances
where
there
was
a
controlling
interest
within
the
meaning
of
the
proviso
he
could,
even
if
there
had
been
no
proviso,
have
accomplished
through
the
exercise
of
his
discretion
exactly
the
same
policy
as
that
which
is
embodied
in
the
proviso.
If
in
such
cases
he
had
continued
to
allow
only
the
same
deductions
in
respect
of
depreciation
as
he
had
allowed
previously
I
cannot
see
how
it
could
reasonably
have
been
argued
that
his
allowance
were
not
within
his
discretion.
Indeed,
it
seems
to
me
that
Parliament
deliberately
changed
the
law
in
order
to
enable
the
Minister
to
take
such
a
course
of
action
as
that
which
he
took
in
this
case
without
running
the
risk
of
having
it
set
aside
as
was
done
in
the
Pioneer
Laundry
case
(supra)
under
a
different
state
of
the
law.
That
being
so,
I
am
unable
to
find
any
reason
for
thinking
that
after
the
proviso
was
enacted
the
Minister
was
precluded
from
doing
what
he
could
have
done
if
there
had
been
no
proviso.
If
the
Minister’s
assessment
officers,
including
the
writer
of
the
letter,
thought
that
the
existence
of
a
controlling
interest
within
the
meaning
of
the
proviso
made
it
obligatory
to
base
the
depreciation
allowance
on
the
cost
of
the
buildings
to
their
former
owner
they
were
in
error
in
so
thinking.
The
proviso
gives
no
such
direction
to
the
Minister
and
does
not
prescribe
any
such
base
or,
indeed,
any
base.
It
is
silent
on
the
matter,
which
is
consistent
with
the
fact
that
the
allowance
of
deductions
in
respect
of
depreciation
is
expressly
left
to
the
discretion
of
the
Minister
by
the
opening
words
of
the
section.
But
the
letter
does
not
say
that
the
Minister
was
bound
by
the
proviso
to
take
the
proposed
course.
To
have
said
that
would
have
implied
a
denial
of
the
Minister’s
discretion
under
the
opening
words
of
the
section
and
the
substitution
of
a
statutory
obligation
under
the
proviso.
No
such
implication
should
be
imputed
to
the
writer
of
the
letter
and
no
such
meaning
should
be
read
into
it.
What
the
letter
in
effect
said
was
that
the
proposed
action
would
be
taken
because
of
the
proviso.
That
is
a
different
thing
from
saying
that
the
proviso
compelled
the
proposed
action.
Thus,
there
is
no
justification
in
the
letter
for
finding
that
the
Minister
did
not
exercise
his
discretion
on
proper
principles.
It
is
important
to
appreciate
what
the
proviso
did
and
what
bearing
it
had
on
the
situation
under
review.
It
set
a
top
limit
to
the
total
amount
of
deductions
in
respect
of
depreciation
that
could
be
allowed
in
the
case
of
assets
acquired
under
the
circumstances
specified
in
it.
When
the
aggregate
of
these
deductions
reached
the
cost
of
the
assets
to
their
former
owner
no
further
allowance
of
deductions
was
to
be
made
and
the
Minister’s
discretion
to
allow
deductions
came
to
an
end.
The
proviso
clearly
embodies
a
policy
deliberately
adopted
by
Parliament
to
restrict
the
allowance
of
deductions
in
respect
of
depreciation
in
the
case
of
assets
acquired
under
the
circumstances
specified
in
the
proviso
to
the
cost
of
such
assets
to
their
former
owner.
Thus,
while
the
proviso
does
not
direct
the
Minister
to
base
his
allowance
of
deductions
in
respect
of
the
depreciation
of
such
assets
on
their
cost
to
their
former
owner
there
is
nothing
in
the
proviso
or
elsewhere
that
precludes
him
from
using
such
a
base.
Moreover,
the
fact
that
the
proviso
does
not
apply
in
this
case,
in
the
sense
that
its
prohibition
is
not
operative
for
the
reason
already
explained,
does
not
mean
that
it
is
devoid
of
effect
and
must
be
totally
disregarded,
as
counsel
for
the
respondent
contended
and
Mr.
Fisher
decided.
On
the
contrary,
the
Minister
must
consider
the
proviso
before
he
deals
with
a
claim
for
deduction
in
respect
of
depreciation.
Each
year
when
such
a
claim
is
made
it
is
the
duty
of
the
Minister
to
determine
whether
the
proviso
applies
or
not.
If
he
is
satisfied
that
the
assets
were
acquired
under
circumstances
that
bring
them
within
the
purview
of
the
policy
embodied
in
the
proviso
he
must
then
determine
whether
the
top
limit
of
the
permissible
allowances
of
deduction
in
respect
of
depreciation
of
such
assets
has
been
reached.
If
it
has
not,
he
knows
that
the
total
amount
of
depreciation
deduction
that
may
still
be
allowed
in
respect
of
such
assets
is
the
difference
between
the
aggregate
of
the
deductions
which
have
been
allowed
and
the
cost
of
such
assets
to
their
former
owner.
It
is
in
respect
of
this
balance
that
he
must
exercise
his
discretion.
Thus,
each
year
his
attention
is
directed
to
the
policy
of
the
proviso
and
he
must
pay
attention
to
it.
Likewise,
it
seems
to
me
that
the
Court
ought
not
to
adopt
any
interpretation
of
the
proviso
that
flouts
the
policy
that
underlies
it.
When
the
Minister
after
determining
that
under
the
proviso
there
is
still
a
difference
between
the
aggregate
amount
of
deductions
in
respect
of
depreciation
of
the
assets
in
question
which
have
been
allowed
and
their
cost
to
the
former
owner
so
that
the
proviso
has
not
yet
operative
effect
and
his
discretion
to
allow
deductions
is
still
vested
in
him
up
to
the
amount
of
the
difference
how
can
it
possibly
be
said
that
he
must
not
base
his
allowance
of
a
deduction
on
the
cost
of
the
assets
to
their
former
owner?
To
say
so
is
to
deny
his
discretion.
Similarly,
by
what
right
can
the
new
owner
of
the
assets
assert,
as
Mr.
Fisher
did,
that
the
allowance
must
be
based
on
the
cost
of
the
assets
to
him?
To
admit
this
is
to
say,
as
the
Income
Tax
Appeal
Board
in
effect
did,
that
the
Minister’s
actual
exercise
of
his
discretion
is
reviewable
by
the
Court
and
that
it
may
substitute
its
opinion
of
what
should
be
done,
as
the
Income
Tax
Appeal
Board
in
effect
did,
for
the
Minister’s
exercise
of
his
discretion,
There
is
no
judicial
authority
of
which
I
have
any
knowledge
that
sanctions
any
such
review
or
substitution.
F'or
the
same
reason,
I
am
unable
to
agree
with
the
submission
that
the
Minister
in
the
exercise
of
his
discretion
must
act
in
accordance
with
the
requirements
of
sound
accounting
practice
and,
therefore,
relate
his
allowance
of
deductions
in
respect
of
depreciation
of
the
buildings
to
their
cost
to
the
respondent
according
to
its
books.
This
submission
really
requires
no
answer
for
it
is
tantamount
to
substituting
the
accountant’s
opinion
for
the
Minister’s
discretion.
There
is
no
necessary
relationship
between
the
amount
of
deduction
in
respect
of
depreciation
of
an
asset
that
may
be
set
up
in
the
taxpayer’s
books
and
the
amount
of
the
deduction
from
what
would
otherwise
be
taxable
income
that
may
be
allowed.
The
former
is
for
the
accountant
and
the
taxpayer,
the
latter
for
the
taxing
authority
under
the
taxing
Act.
Thus
accounting
practice
must
give
way
to
the
discretion
that
Parliament
has
vested
in
the
Minister.
This
does
not
mean
that
there
are
no
limitations
on
the
Minister’s
exercise
of
his
discretion.
He
must
not
act
arbitrarily.
This,
indeed,
is
inherent
in
the
concept
of
discretion
itself
as
was
stated
by
the
House
of
Lords
in
Sharp
v.
Wakefield,
[1891]
A.C.
173,
where
Lord
Halsbury,
L.C.,
said,
at
page
179:
“
‘
discretion’
means
when
it
is
said
that
something
is
to
be
done
within
the
discretion
of
the
authorities
that
that
something
is
to
be
according
to
the
rules
of
reason
and
justice,
not
according
to
private
opinion:
Rooke’s
case
(5
Rep.
100,
a);
according
to
law,
and
not
humour.
It
is
to
be,
not
arbitrary,
vague,
and
fanciful,
but
legal
and
regular.
And
it
must
be
exercised
within
the
limit,
to
which
an
honest
man
competent
to
the
discharge
of
his
office
ought
to
confine
himself
:
Walson
v.
Rastall
(4
T.R.
at
p.
754).’’
This
statement
is
really
a
definition
of
what
discretion
is.
There
was
nothing
in
the
Minister’s
action
that
offended
against
the
precepts
of
this
statement.
How
could
it
be
said
that
it
was
arbitrary,
vague
or
fanciful
on
the
part
of
the
Minister
to
base
his
allowance
of
a
deduction
in
respect
of
the
depreciation
of
the
buildings
on
their
cost
to
their
former
owner
when
Parliament
itself
enacted
that
such
cost
was
the
top
limit
of
the
deductions
in
respect
of
their
depreciation
that
could
be
allowed.
If
I
were
called
upon
to
express
an
opinion
on
the
Minister’s
actual
course
of
action
I
would
have
no
hesitation
in
saying
that
it
was
more
consistent
with
the
policy
of
Parliament,
as
embodied
in
the
proviso,
than
the
action
desired
by
the
respondent
and
approved
by
the
Income
Tax
Appeal
Board
would
have
been.
But
the
Court
is
not
called
upon
to
express
any
such
opinion
for
Parliament
has
expressly
preferred
the
opinion
of
the
Minister
in
the
exercise
of
his
discretion.
If
he
has
actually
exercised
his
discretion
the
Court
has
no
right
to
interfere
with
it
even
if
it
would
have
come
to
a
different
conclusion
if
the
matter
had
been
one
for
it
to
decide.
Thus,
I
see
no
reason
for
finding
that
the
Minister
acted
on
wrong
principles
in
exercising
his
discretion
as
he
did.
I
do
not
think
that
the
letter
proves
that
the
Minister
was
mistaken
in
his
interpretation
of
the
proviso.
On
the
contrary,
the
action
taken
was
in
harmony
with
it.
But
even
if
he
had
been
mistaken
this
would
not
have
made
his
action
an
improper
one
for
the
Court
is
concerned
with
the
question
whether
what
he
did
was
within
his
discretion
to
do
rather
than
with
why
he
did
it.
It
is
quite
possible
that
the
reason
for
doing
a
thing
may
be
challenged
but
the
thing
done
is
proper.
Many
a
judgment
has
been
affirmed
on
appeal
although
the
reasons
given
for
it
were
erroneous.
Moreover,
there
are,
I
think,
sound
reasons
for
saying
that
when
Parliament
made
the
changes
I
have
referred
to
it
made
the
discretion
which
it
vested
in
the
Minister
an
administrative
discretion
rather
than
a
quasi-judicial
one.
In
that
view,
the
consideration
that
may
have
moved
him
to
the
actual
exercise
of
his
discretion
is
not
a
matter
for
inquiry
by
the
Court.
There
are
numerous
decisions
of
outstanding
authority
that
establish
this
principle:
vide,
for
example,
Julius
v.
Lord
Bishop
of
Oxford
(1880),
5
App.
Cas.
214,
and
especially,
Alleroft
v.
Lord
Bishop
of
London,
[1891]
App.
Cas.
666.
In
my
judgment,
there
is
no
justification
for
finding
that
the
Minister’s
action
in
this
case
was
otherwise
than
in
accord
with
the
proper
exercise
of
his
discretion.
F'or
the
reasons
given,
the
appeal
herein
must
be
allowed
with
costs
and
the
assessment
appealed
against
restored.
Judgment
accordingly.
