CAMERON,
J.:—This
is
an
appeal
from
a
decision
of
the
Income
Tax
Appeal
Board
dated
April
24,
1956
(15
Tax
A.B.C.
62),
dismissing
the
appellant’s
appeal
from
a
reassessment
dated
June
29,
1955,
in
respect
of
the
appellant’s
taxation
year
ending
March
31,
1953.
At
the
Board
hearing
no
evidence
was
led
on
behalf
of
the
appellant
and
the
chairman
held
that
in
view
of
the
complete
lack
of
evidence
there
was
nothing
before
him
to
warrant
any
change
in
the
reassessment.
The
principal
facts
are
not
in
dispute.
The
business
of
the
appellant
is
that
of
general
contracting,
its
work
consisting
mainly
of
road
building.
In
May
1949,
it
purchased
a
‘used
Model
6,
Northwestern
power
shovel
at
a
cost
of
$27,075;
it
was
of
the
type
shown
on
page
B
of
Exhibit
1.
It
was
powered
by
a
Murphy
M.E.6
diesel
engine
having
a
rated
capacity
of
125
h.p.;
the
engine
was
probably
new
when
it
was
installed
in
the
shovel
in
1948
although
there
is
no
clear
evidence
on
that
point.
The
shovel
was
used
by
the
appellant
in
its
operations
in
Ontario
and
Newfoundland
in
1949,
moving
approximately
130,000
eubie
yards
of
earth
and
rock.
In
each
of
the
next
three
years
it
was
used
in
Newfoundland
moving
about
100,000
cubic
yards
of
rock
and
earth
annually.
These
operations,
particularly
in
Newfoundland,
were
said
to,
be
of
an
extremely
heavy
and
rugged
nature,
entailing:an
unusual
amount
of.
wear
and
tear
on
the
shovel
and
its
parts,
including
the
engine.
In
the
spring
of
1951,
the
engine
was
completely
overhauled
at
a
cost
of
about
$3,500.
In
1952
further
sums
of
$900
for
parts
and
$600
for
labour
were
expended
in
repairing
the
engine.
These
outlays
were
allowed
as
deductions
for
the
year
in
which
they
were
incurred.
In
January
1953,
the
directors
of
the
appellant
company
found
that
major
repairs
were
again
needed,
both
for
the
shovel
and
the
engine.
It
was
estimated
that
the
cost
of
putting
the
engine
in
good
condition
would
be
approximately
the
same
as
had
been
expended
on
it
in
1951,
namely,
$3,500.
The
directors,
however,
came
to
the
conclusion
that
it
would
be
wiser
to
instal
a
new
engine;
accordingly
the
appellant
then
purchased
a
new
Caterpillar
D.
13,000
engine
with
a
rated
capacity
of
125
h.p.,
at
a
cost
of
$8,894,
and
installed
it
in
the
shovel.
Exhibit
2
is
the
conditional
sale
contract
entered
into
by
the
purchase
of
the
engine,
dated
January
26,
1953;
it
shows
that
Crothers
Limited
(the
vendors)
in
part
payment
of
the
purchase
price
took
over
the
old
engine,
allowing
therefor
a
trade-in-value
of
$3,200.
With
some
adjustments,
the
net
cost
of
the
new
engine
to
the
appellant
totalled
$6,006.13.
In:
computing
its
income
tax
return
for
the
taxation
year
ending
March
31,
1953,
the
appellant
showed
an
item
of
expense
entitled
"‘Repairs
to
shovel—$11,671.32”.
Included
in
that
amount
was
the
net
cost
of
the
new
engine,
namely,
$6,006.13.
In
reassessing
the
appellant,
the
respondent
disallowed
the
latter
amount
entirely
as
an
expense,
added
it
to
the
declared
taxable
income
and
then
deducted
30
per
cent
thereof
($1,801.84)
as
a
capital
cost
allowance.
The
appellant
objected
to
that
assessment,
its
stated
reasons
being—
We
feel
that
it
is
most
essential
that
the
full
maintenance
of
our
equipment
be
allowed
as
an
expense
when
incurred
during
the
period
it
is
in
operation
and
earning
income.”
By
his
Notification,
the
respondent
confirmed
the
assessment
as
having
been
made
in
accordance
with
the
provisions
of
the
Act
and
in
particular
on
the
ground
that—
"‘The
cost
of
a
Caterpillar
D.
13,000
engine
claimed
as
a
deduction
from
income
was
not
an
outlay
or
expense
incurred
by
the
taxpayer
for
the
purpose
of
gaining
or
producing
income
within
the
meaning
of
paragraph
(a)
of
subsection
(1)
of
section
12
of
the
Act,
but
was
a
capital
outlay
within
the
meaning
of
paragraph
(b)
of
the
said
subsection
(1)
of
section
12.”
Forming
part
of
the
appellant’s
return
is
a
schedule
of
fixed
assets
and
capital
cost
allowances
as
at
March
31,
1953.
This
statement
shows
that
since
the
purchase
of
the
power
shovel
(including
the
engine)
in
1949
at
a
cost
of
$27,075,
the
shovel
had
been
treated
as
a
depreciable
asset
and
the
capital
cost
allowance
in
respect
thereof
had
been
allowed
annually
under
the
regulations
authorized
by
the
provisions
of
Section
11(1)
(a)
of
the
Income
Tax
Act.
It
is
common
ground
that
up
to
the
taxa-
tion
year
ending
March
31,
1952,
the
shovel
as
a
whole
was
treated
by
both
parties
as
being
within
Class
(h)
of
Class
10
of
Schedule
B
to
the
Regulations,
namely,
‘‘contractors’
movable
equipment
(including
portable
camp
buildings)’’,
the
rate
of
capital
cost
allowances
in
such
being
30
per
cent.
The
statement
that
I
have
referred
to
also
shows
that
at
March
31,
1952,
depreciation
of
$17,788.27
had
been
taken
on
the
shovel,
thus
reducing
its
book
value
as
of
that
date
to
$9,286.73.
In
the
statement
referred
to,
a
further
30
per
cent
depreciation
was
claimed
and
allowed,
thus
reducing
the
book
value
as
of
March
31,
1953,
to
$6,500.71.
For
depreciation
purposes,
that
amount
would
have
correctly
shown
the
book
value
of
the
shovel
as
a
whole
had
the
old
engine
not
been
replaced.
As
both
parties
rely
on
the
provisions
of
Section
12(1)
of
The
1948
Income
Tax
Act,
as
amended,
I
will
quote
at
once
the
relevant
portions
thereof
as
they
were
in
the
taxation
year
in
question
:
“12.
(1)
In
computing
income,
no
deduction
shall
be
made
in
respect
of
(a)
an
outlay
or
expense
except
to
the
extent
that
it
was
made
or
incurred
by
the
taxpayer
for
the
purpose
of
gaining
or
producing
income
from
property
or
a
busi-
ness
of
the
taxpayer,
(b)
an
outlay,
loss
or
replacement
of
capital,
a
payment
on
account
of
capital
or
an
allowance
in
respect
of
depreciation,
obsolescence
or
depletion
except
as
expressly
permitted
by
this
Part,”
For
the
appellant
it
is
submitted
that
the
net
outlay
for
the
new
engine
was
an
expense
incurred
for
the
purpose
of
gaining
or
producing
income
from
its
business
and
was
therefore
within
the
exception
stated
in
para.
(a)
;
and
that
consequently
it
is
deductible
in
full.
Further,
it
is
submitted
that
the
outlay
was
not
of
a
capital
nature
and
did
not
fall
within
the
provisions
of
para.
(b).
The
respondent,
on
the
other
hand,
submits
that
the
outlay
was
not
incurred
for
the
purpose
of
gaining
or
producing
income
from
the
appellant’s
business
within
the
meaning
of
the
exception
stated
in
para.
(a),
but
rather
was
an
outlay
on
account
of
capital
and
therefore
barred
from
deduction
by
the
provisions
of
para.
(b).
I
must
admit
that
I
have
found
some
difficulty
in
ascertaining
the
precise
meaning
of
para.
(a).
If
an
outlay
or
expense
falls
within
the
exception
therein
as
being
one
made
or
incurred
by
the
taxpayer
for
the
purpose
of
gaining
or
producing
income
from
property
or
a
business
of
the
taxpayer,
does
it
necessarily
follow
that
the
outlay
is
deductible
if
it
has
also
passed
the
primary
test
referred
to
by
the
President
of
this
Court
in
The
Royal
Trust
Company
v.
M.N.R.,
[1957]
C.T.C.
32,
namely,
that
it
was
made
or
ineurred
by
the
taxpayer
in
accordance
with
the
ordinary
principles
of
commercial
trading,
or
well
accepted
principles
of
business
practice?
In
that
view,
the
deduction
of
expenses
not
prohibited
by
para.
(a)
is
thereby
‘‘granted’’.
Support
for
that
view
may
be
found
in
Smith
v.
Incorporated
Cüunci
of
Law
Reporting
for
England
and
Wales,
6
T.C.
477
at
482
(referred
to
in
Simon’s
Income
Tax,
Vol.
2,
p.
202),
in
which
Serutton,
-J.,
said:
‘That
form
of
words
contemplates
that
certain
deductions
are
to
be
allowed;
what
one
finds
is
that
certain
deductions
are
prohibited,
but
in
some
cases
the
prohibition
is
in
this
form:
‘No
deductions
shall
be
made
except’;
and
from
that
system
of
exceptions
one
ascertains,
rather
unscientifically
as
a
it
seems
to
me,
what
deductions
are
in
fact
allowed.”
The
difficulty
I
have
found
in
accepting
that
view
of
the
matter
is
that
the
phrase
"‘for
the
purpose
of
earning
the
income’
found
i
in
the
former
Section
6(1)
(a)
of
the
Income
War
Tax
Act
has:
been
interpreted
to
mean
‘‘in
the
process
of
earning
the
income’’
(Dominion
Natural
Gas
Co.
Ltd.
v.
M.N.R.,
[1941]
S.C.R.
19;
[1940-41]
C.T.C.
155.
That
subsection
was
considered
generally
as
referable
only
to
operating
and
maintenance
expenses.
Under
the
Income
Tax
Act,
however,
a
very
similar
phrase,
‘‘for
the
purpose
of
gaining
or
producing
income
therefrom
(property)
or
for
the
purpose
of
gaining
or
producing
income
from
a
business’’,
used
in
Section
20(4)
(a)
and
(b),
is
made
clearly
applicable
to
Section
11(1)
(a)
which
is
the
statutory
authority
for
the
deduction
of
capital
cost
allowances.
It
is
perhaps
arguable,
at
least,
that
para.
(a)
of
Section
12(1)
is
broad
enough
in
its
terms—and
when
considered
by
itself—
to
permit
the
deduction
of
all
outlays
or
expenses
made
or
incurred
for
the
purpose
of
producing
income
whether
such
outlays
be
of
a
capital
or
revenue
nature.
I
am
satisfied,
however,
that
whatever
be
the
true
interpretation
to
be
put
upon
para.
(a)
of
Section
12(1),
it
cannot
be
read
by
itself
or
as
providing
the
sole
test
of
deductibility.
The
primary
test
is
that
referred
to
above
in
the
Royal
Trust
Company
case.
Moreover,
if
the
outlay
in
question
passes
the
test
of
the
excepting
portion
of
the
paragraph,
its
deduction
will
be
denied
if
it
be
specifically
excluded
by
any
other
provision
of
the
Act.
For
example,
para.
(c)
of
Section
12(1),
relating
to
exempt
income,
is
clearly
an
additional
limitation
to
the
general
limitations
of
para.
(a).
Similarly,
if
the
outlay
be
within
the
ambit
of
para,
(b)
(supra),
the
deduction
will
not
be
allowed.
In
a
broad
sense
it
may
be
said
that
the
outlay
for
the
new
engine
was
an
expense
incurred
for
the
purpose
of
earning
the
appellant’s
income.
The
same
might
be
said
of
all
outlays
of
capital
for
all
types
of
buildings,
machinery
and
the
like,
to
be
used
in
the
business.
In
the
instant
case,
the
provision
of
a
new
engine
enabled
the
appellant
to
earn
income
from
the
operation
of
the
shovel
without
the
likelihood
of
frequent
breakdowns.
The
real
question,
therefore,
is
whether
that
outlay
was
one,
the
deductibility
of
which
was
prohibited
by
para.
(b).
For
the
appellant,
it
is
submitted
that.
the
outlay
here
in
question
was
in
the
nature
of
a
repair;
that
by
reason
of
the
rugged
nature
of
the
company’s
operations,
the
old
engine
had
worn
out
to
a
substantial
extent;
that
to
put
it
in
a
condition
in
which
it
could
be
used
for
the
purpose
of
producing
income
for
the
appellant
it
was
necessary
either
to
incur
heavy
repair
bills
or,
alternatively,
to
replace
the
worn-out
engine,
and
the
latter
alternative
was
decided
upon.
Then
it
is
said
that
the
engine
was
merely
a
subsidiary
part
of
the
"‘entirety”,
that
is,
the
power
shovel;
that
the
replacement
of
the
engine
was
therefore
not
a
replacement
of
the
‘‘entirety’’
but
merely
of
a
subsidiary
part
of
the
whole.
It
is
pointed
out
that
the
new
engine
was
of
precisely
the
same
rated
capacity
as
the
former
engine
and
did
not
constitute
an
improvement
over
the
old
engine;
that
the
replacement
of
the
engine
merely
restored
the
shovel
to
its
original
condition
so
that
it
could
continue
to
earn
revenue.
By
this
argument
it
is
sought
to
bring
the
case
within
the
decision
of
the
Court
of
Session
in
Samuel
Jones
&
Company
(Devondale),
Ltd.
v.
C.I.R.,
32
T.C.
513.
The
headnote
in
that
case
is
as
follows
:
“The
Company
carried
on
a
trade
of
processing
paper.
A
chimney
of
its
factory
was
replaced
because
of
its
dangerous
condition
but
the
replacement
did
not
constitute
an
appre-
ciable
improvement.
The
Company
claimed
a
deduction
in
computing
its
profits
for
Income
Tax
purposes
of
the
cost
of
removing
the
old
chimney
and
building
the
new
one.
On
appeal
before
the
Special
Commissioners
it
was
contended
for
the
Company
that
the
chimney
was
an
integral
part
of
the
unit,
which
unit
was
the
factory
as
a
whole;
that
the
expenditure
on
the
new
chimney
was
to
maintain
the
revenue-earning
capacity
of
the
factory;
and
that
removal
of
the
old
chimney
was
in
the
nature
of
a
repair.
It
was
contended
on
behalf
of
the
Crown
that
the
replacement
of
the
chimney
was
capital
expenditure
;
that
the
expenditure
incurred
should
be
borne
by
the
owner
as
such
and
not
by
the
trader;
and
that
any
deduction
should
be
given
under
Rule
8(a)
of
No.
V
of
Schedule
A,
and
not
under
Schedule
D.
The
Commissioners
held
that
the
cost
of
replacement
of
the
chimney
was
capital
expenditure
but
allowed
the
cost
of
removing
the
old
chimney.
Held,
that
the
whole
cost
of
replacing
the
chimney
(including
the
cost
of
removing
the
old
chimne
)
was
an
admissible
deduction.
’
‘
In
that
case
the
Lord
President
(Cooper)
said
at
page
518:
..
but
so
far
as
this
case
is
concerned
the
facts
seem
to
me
to
demonstrate
beyond
a
doubt
that
the
chimney
with
which
we
are
concerned
is
physically,
commercially
and
functionally
an
inseparable
part
of
an
"‘entirety’’,
which
is
the
factory
.
.
.
It
is
doubtless
an
indispensable
part
of
the
factory,
doubtless
an
integral
part
;
but
none
the
less
a
subsidiary
part,
and
one
of
many
subsidiary
parts,
of
a
single
industrial
profit-earning
undertaking.
So
viewing
the
matter
I
am
unable
to
see
why
the
expense
incurred
in
relation
to
this
transaction
should
not
be
treated
as
an
admissible
revenue
expenditure
on
repairs,
and
I
am
in
part
influenced
in
reaching
that
conclusion
by
the
fact
that
the
factory
as
a
whole
is
insured
for
something
in
the
region
of
£165,000
whereas
the
expense
incurred
in
taking
down
the
old
chimney
and
building
the
substitute
is
only
a
matter
of
£4,300
or
about
2
per
cent.
The
line
of
approach
which
in
a
case
of
this
kind
impresses
me
as
preferable
to
that
adopted
by
Rowlatt,
J.
is
that
which
was
taken
by
the
Privy
Council
in
Rhodesia
Railways,
Ltd.,
[1933]
A.C.
368,
which
although
relating
to
quite
a
different
type
of
subject
seems
to
me
to
afford
a
sounder
basis
in
authority,
in
so
far
as
authority
is
needed,
for
the
contention
which
the
Company
has
brought
before
us.’
It
is
of
particular
interest
to
observe
that
the
Lord
President
was
influenced
in
reaching
his
conclusion
by
the
fact
that
the
expense
incurred
in
taking
down
the
old
chimney
and
building
the
substitute
represented
about
2
per
cent
only
of
the
fully
insured
value
of
the
factory
as
a
whole.
Lord
Carmont,
who
agreed
with
the
opinion
of
the
Lord
President,
was
apparently
influenced
by
the
same
consideration
as
shown
by
the
concluding
paragraph
of
his
opinion
:
‘
i
The
money
value
of
the
renewal
was
relatively
insignificant
.
.
.”
The
other
member
of
the
Court,
Lord
Russell,
gave
no
separate
opinion
but
expressed
himself
as
in
full
agreement
with
the
opinions
of
the
other
members
of
the
Court.
.on
It
may
be
conceded
that
as
a
general
rule
repairs
necessitated
by
the
wear
and
tear
of
equipment
used
in
the
business
are
allowed
as
deductions,
although
no
specific
reference
is
found
in
the
Income
Tax
Act
regarding
4
‘repairs”.
It
may
also
be
conceded
that
in
normal
circumstances
the
repairing
of
machinery
frequently
involves
the
necessity
of.»
replacing
worn-out
parts.
But
I
think
it
is
clear
that
if
the
'outlay
brings
into
existence
a
capital
asset,
such
as
a
new
piece
of
machinery,
such
outlay
will
not
be
allowed
as
a
deduction.
In
the
instant
case
I
have
reached
the
conclusion
that
the
outlay
in
question
did
bring
into
existence
a
new
capital
asset,
namely,
the
new
engine.
The
evidence
is
that
the
old
engine
was
in
use
for
at
least
five
years
and
at
the
end
of
that
period
still
had
a
substantial
commercial
value.
It
is
probable
that
the
new
engine
would
have
a
useful
life
of
at
least
the
same
number
of
years.
The
expenditure
therefore
brought
into
existence
an
advantage
for
the
enduring
benefit
of
the
trade
and
Which
should
be
considered
to
be
a
capital
asset
{Dominion
Natural
Gas
Co.
Ltd.
v.
M.N.R.,
[1941]
S.C.R.

[1940-41]
C.T.C.
155.
In
reaching
the
conclusion
that
the
outlay
was
not
one
on
revenue
account,
I
am
influenced
in
part,
as
were
the
members
of
the
Court
of
Session
in
the
Samuel
Jones
case
{supra),
by
the
magnitude
of
the
outlay
when
related
to
the
value
of
the
power
shovel
as
a
whole.
As
pointed
out
above,
the
total
cost
of
the
new
engine
exceeded
the
written
down
value
of
the
shovel
as
a
whole
after
deducting
all
capital
cost
allowances
made
to
the
end
of
the
appellant’s
taxation
year
1953.
It
seems
to
me,
also,
that
to
allow
a
deduction
in
full
as
an
operating
expense
of
an
outlay
such
as
this
and
which
brought
into
existence
a
new
capital
asset,
would
be
to
frustrate
the
clear
intent
of
the
provisions
of
Section
11(1)
(a)
and
the
regulations
passed
thereunder
in
regard
to
capital
cost
allowances.
As
I
have
stated
above,
claims
for
capital
cost
allowances
were
made
in
previous
years
in
respect
of
the
power
shovel
as
a
whole
and
were
allowed.
It
was
considered
as
a
capital
asset
and.
having
been
purchased
with
the
engine
was
treated
as
one
asset.
If,
for
example,
the
appellant
had
purchased
separately
a
drill
and
an
engine
to
operate
it,
it
would
have
been
entitled
to
claim
capital
cost
allowances
in
respect
of
each.
If,
after
a
few
years’
use,
it
had
been
considered
advisable
to
replace
that
engine
with
a
new
one,
the
appellant
would
have
been
required
to
bring
into
account
the
amount
received
on
the
sale
so
that
depreciation
already
received
might
(in
a
proper
case)
be
recovered,
and
also
the
cost
of
the
new
engine,
so
as
to
ascertain
the
amount
to
which
the
fixed
rate
of
depreciation
would
be
applied.
I
am
unable
to
conclude
that
it
should
be
otherwise
merely
on
the
ground,
as
in
the
instant
case,
that
the
engine
was
installed
in
the
power
shovel.
The
engine
clearly
was
a
marketable
entity,
readily
detached
from
the
power
shovel
by
the
removal
of
a
few
bolts,
and
capable
of
being
used
for
other
purposes.
I
am
of
the
opinion
that
under
the
Income
Tax
Act
and
the
special
provisions
relating
to
capital
cost
allowances,
the
sale
of
a
capital
asset—or
of
a
substantial
part
thereof
as
in
the
instant
case—
and
the
replacement
of
the
asset
or
part
so
sold
by
the
acquisition
of
a
new
asset
or
such
part,
must
be
dealt
with
only
as
has
been
done
in
this
case
by
the
respondent
in
assessing
the
appellant..
I:
have
not
overlooked
the
evidence
given
by
the
witness
J.
S.
Clark
on
behalf
of
the
appellant.
He
has
been
a
publie
accountant
for
twenty
years
and
the
auditor
of
the
appellant
company
since
its
formation.
He
was
of
the
opinion
that
it
was
in
accordance
with
good
business
and
accounting
practice
to
charge
the
net
cost
of
the
engine
as
an
operating
or
maintenance
expense
of
the
year.
He
said
that
when
a
replacement
or
repair
did
not
add
to
the
value
of
the
asset,
the
outlay
in
respect
thereof
should
be
regarded
as
an
operating
or
maintenance
expense.
He
stated
that
he
relied
on
the
authority
of
Professor
Smails’
book
on
Public
Accounts
but
did
not
supply
me
with
the
precise
reference.
I
shall
have
a
word
to
say
later
in
regard
thereto.
Even
if
the
test
suggested
by
the
witness
be
correct,
it
does
not
support
the
appellant’s
case
when
one
considers
the
facts.
It
could
scarcely
be
denied
that
the
installation
of
the
new
engine
did
add
to
the
value
of
the
power
shovel.
The
difference
in
value
of
the
old
and
new
engines
as
shown
by
the
conditional
sales
contract
was
approximately
$5,000,
and
surely
that
must
have
increased
the
value
of
the
shovel
by
a
very
substantial
amount.
As
I
have
been
unable
to
find
the
Canadian
textbook
of
Professor
Smails
referred
to
by
the
witness
Clark,
I
think
that
he
probably
had
in
mind
that
author’s
text
on
Accounting
Principles
and
Practice.
In
the
5th
edition
of
1954,
the
author,
in
commenting
on
the
distinction
between
capital
expenditures
and
revenue
expenditures,
states
the
modern
view
by
referring
to
two
American
authors,
as
follows:
“The
modern
view
can
best
be
expressed
by
quotation
from
two
American
authors.
‘One
phase
of
the
distinction
between
capital
and
revenue
is
presented
by
the
terms
‘
‘‘capital
expenditure”
and
‘‘revenue
expenditure’’.
The
former
relates
to
an
expenditure
for
property
of
a
life
duration
extending
over
several
accounting
periods,
the
latter
to
an
expenditure
for
property.
which
will
be
consumed
within
one
accounting
period.
This
particular
distinction
is
perhaps
not
especially
significant
;
it
refers
to
the
first
classification
of
expenditures
between
those
expected
to
be
charged
against
revenue,
and
those
expected
to
be
charged
to
an
asset
account
and
thus
carried
forward
into
succeeding
periods.
The
really
important
distinction
between
capital
and
revenue
charges
is
that
which
is
effectuated
at
the
end
of
the
accounting
period,
when
all
the
accounts
are
reviewed
for
the
purpose
of
separating
consumed
costs.
from
unconsumed
costs.’
(T.
H.
Sanders,
Progress
in
Development
of
Basic
Concepts,
p.
13.)
‘Some
writers
have
suggested
that
the
distinction
between
capital
and
income
is
a
fundamental
principle
of
accounting.
However,
the
distinction
in
accounting
today
between
so-called
capital
expenditures
and
income
expenditures
does
not
rest
on
any
such
essential
difference
in
the
nature
of
the
property
acquired
as
that
between
land
and
other
property
which
is
often
stressed
in
the
field
of
economics.
The
distinction
rests
rather
upon
the
relation
between
the
length
of
the
useful
life
of
the
property
acquired
and
the
length
of
the
accounting
period
for
which
income
is
being
determined.
A
capital
expenditure
is
one,
the
usefulness
of
which
is
expected
to
extend
over
several
accounting
periods.
If
the
accounting
period
were
increased
from
the
customary
year
to
a
decade,
most
of
what
is
now
treated
as
capital
expenditure
would
become
chargeable
to
income,
while
if
the
period
were
reduced
to
a
day,
much
of
what
is
now
treated
as
current
maintenance
would
become
capital
expenditure.’
(C.

May,
Financial
Accounting,
p.
45.)
”
I
need
not
comment
on
this
opinion
of
Professor
Smails
except
to
state
that
it
does
not
warrant
the
interpretation
placed
thereon
by
the
witness
Clark.
It
does
seem,
however,
to
support
the
view
which
I
have
expressed
that
the
outlay
for
the
purchase
of
the
new
engine
would
properly
be
considered
in
accounting
practice
as
a
capital
expenditure
because
of
the
enduring
nature
of
the
new
asset.
For
these
reasons,
I
am
of
the
opinion
that
the
appeal
fails.
Accordingly,
it
will
be
dismissed
and
the
assessment:
affirmed.
The
respondent
is
entitled
to
costs
after
taxation.
Judgment
accordingly.
