J.T.C.C.:-
Introduction
These
appeals
are
from
assessments
for
the
appellant’s
1991
and
1992
taxation
years.
They
have
to
do
with
the
disallowance
by
the
Minister
of
National
Revenue
of
a
portion
of
the
contribution
made
by
Mr.
Goldstein
to
a
registered
retirement
savings
plan.
In
1991
and
1992
respectively,
the
appellant
deducted
$8,443
and
$7,160
as
contributions
to
his
RRSP.
The
Minister,
on
assessing,
reduced
his
allowable
deductions
for
those
years
to
$6,736
and
$5,646
respectively.
The
difference
between
the
Minister
and
the
appellant
lies
in
the
computation
of
the
appellant’s
’’earned
income".
Earned
income,
as
defined
in
paragraph
146(1)(c),
is
a
factor
in
the
formula
used
in
calculating
the
taxpayer’s
"RRSP
deduction
limit"
as
defined
in
paragraph
146(1)(g.1),
which
in
turn
is
a
component
in
the
determination
of
the
amount
of
RRSP
premiums
deductible
under
subsection
146(5).
If
the
taxpayer’s
earned
income
is
reduced
this
may
reduce
the
amount
of
RRSP
contributions
that
are
deductible.
The
issue
is
the
treatment
in
the
computation
of
the
appellant’s
earned
income
of
losses
sustained
by
the
appellant
as
a
limited
partner
in
two
limited
partnerships
that
owned
multiple-unit
residential
buildings
("MURBs").
The
losses
sustained
by
the
partnerships
were
from
the
rental
of
property
and
the
amount
allocated
to
the
appellant
represented
his
share
of
the
partnership’s
losses.
The
appellant
excluded
these
losses
from
the
computation
of
his
earned
income
whereas
the
Minister
deducted
them.
Hence
the
question.
A
second
issue
is
whether
the
Minister,
having
through
his
officials
confirmed
to
the
appellant
that
under
his
then
prevailing
interpretation
of
the
words
"earned
income"
in
section
146
there
were
to
be
excluded
the
appellant’s
share
of
losses
of
a
limited
partnership
that
owned
rental
properties
that
were
MURBs,
is
estopped
from
taking
a
different
position
on
assessing.
Facts
Mr.
Goldstein
in
1991
and
1992
and
in
prior
years
was
a
limited
partner
in
two
limited
partnerships,
Royal
Lady
Manor
Limited
and
Waters
Edge
Tower
Limited.
The
income
or
loss
from
these
partnerships
was
derived
from
the
rental
of
real
property.
In
both
years
the
partnerships
sustained
losses
and
the
appellant’s
share
thereof,
in
the
case
of
Royal
Lady
Manor
Limited
partnership,
was
$2,492
and
$796
and,
in
the
case
of
Waters
Edge
Tower
Limited
partnership,
was
$18,115
and
$17,977.
These
losses
were
claimed
and
allowed
in
the
computation
of
the
appellant’s
income.
In
computing
the
amount
of
RRSP
premiums
that
he
could
deduct
the
appellant
was
required
to
determine
his
"earned
income"
for
the
purposes
of
section
146
of
the
Income
Tax
Act,
R.S.C.
1952,
c.
148
(am.
S.C.
1970-71-72,
c.
63)
(the
"Act").
To
this
end
he
consulted
his
accountants,
Ernst
&
Young,
to
determine
whether
the
losses
that
he
had
sustained
as
a
limited
partner
in
the
two
partnerships
should
be
deducted
in
computing
his
"earned
income".
A
partner
in
Ernst
&
Young,
Mr.
T.R.
Burpee,
testified
as
an
expert
witness
and
he
put
in
evidence
a
memorandum
dated
April
23,
1991
which
had
been
prepared
following
Mr.
Goldstein’s
consultation.
Since
the
memorandum
sets
out
accurately
the
representations
upon
which
the
argument
of
estoppel
is
based,
I
reproduce
it
in
its
entirety:
Re:
RRSP
Earned
Income
Definition
Question
Mr.
Stanley
Goldstein
owns
units
of
a
limited
partnership
which
was
set
up
to
hold
a
multiple-unit
residential
building
("MURB”).
He
has
asked
us
to
review
whether
the
income
or
losses
realized
from
this
limited
partnership
should
be
considered
in
the
calculation
of
earned
income
for
purposes
of
the
RRSP
deduction.
Facts
Earned
income
is
defined
under
paragraph
146(1
)(c)
of
the
Income
Tax
Act
and
Article
925
of
the
Quebec
Taxation
Act.
Earned
income
includes
income
and
losses
realized
by
a
taxpayer,
either
alone
or
as
a
partner
actively
engaged
in
a
business.
It
also
includes
income
from
property,
where
such
income
or
loss
is
derived
from
the
rental
of
real
property.
It
is
apparent
that
any
limited
partnership
income
or
losses
are
not
income
or
losses
incurred
by
a
taxpayer
engaged
actively
in
the
business,
since
a
limited
partner
only
has
limited
involvement
in
the
partnership.
It
is
also
apparent
that
MURB
rental
income
or
losses
are
property
income
or
losses,
which
are
usually
included
in
the
computation
of
earned
income.
However,
in
this
case,
any
income
or
loss
from
Mr.
Goldstein’s
MURB
investment
is
technically
income
from
a
partnership
in
which
he
is
not
actively
engaged,
which
is
not
specifically
referred
to
in
the
definition
of
earned
income.
The
question
of
whether
limited
partnership
income
or
losses
from
the
rental
of
real
property
should
affect
the
computation
of
earned
income
is
complex.
I
concluded
that
income
or
losses
from
a
limited
partnership
are
not
included
in
the
calculation
of
earned
income,
since
they
excluded
from
the
definitions
of
earned
income
in
paragraph
146(l)(c)
of
the
Income
Tax
Act,
and
Article
925
of
the
Quebec
Taxation
Act.
Findings
In
order
to
ensure
that
the
administrative
practices
of
the
federal
and
Quebec
taxation
authorities
are
consistent
with
the
above
conclusion,
I
contacted
Mr.
Wayne
Harding
of
Revenue
Canada,
Rulings
in
Ottawa,
concerning
the
above
issue.
He
indicated
that
even
though
MURBs
are
rental
properties,
the
income
or
loss
from
which
is
included
in
earned
income
calculations,
the
fact
that
the
MURB
is
legally
set
up
as
part
of
a
limited
partnership
signifies
that
income
or
losses
from
this
partnership
do
not
affect
earned
income.
The
reasoning
behind
this
decision
is
that
the
overriding
factor
is
the
limited
partnership
format,
which
indicates
that
any
income
or
loss
from
such
a
limited
partnership
is
not
specifically
referred
to
in
paragraph
146(1
)(c)
of
the
Income
Tax
Act
and
thus
does
not
affect
earned
income.
Linda
Hyatt
of
Ernst
&
Young
in
Toronto
has
dealt
with
a
similar
situation
and
has
contacted
Mr.
John
Carey
of
Revenue
Canada,
Appeals
Division.
Mr.
Carey
indicated
that
Revenue
Canada
was
presently
reviewing
the
definition
of
earned
income,
and
attempting
to
include
rental
income
and
losses
from
limited
partnerships
in
its
definition.
However,
Revenue
Canada
has
been
unable
to
make
a
final
decision
on
this
issue
and
has
therefore
agreed
to
leave
their
policy
unchanged;
that
is,
limited
partnership
rental
income
and
losses
are
not
included
in
the
definition
of
earned
income.
I
also
contacted
Fabienne
Fortier
of
Revenue
Quebec
in
Montreal,
who
confirmed
that
the
Quebec
treatment
is
the
same
as
that
of
the
federal
government.
Conclusion
In
conclusion,
any
income
or
loss
from
a
MURB
set
up
as
a
limited
partnership
does
not
affect
earned
income
calculations.
Thus,
it
is
advantageous
for
a
MURB
to
be
set
up
in
a
limited
partnership
for
investors
who
want
to
enjoy
the
tax
deductions
offered
by
MURB
rental
losses,
and
yet
want
to
maximize
their
earned
income
for
RRSP
contribution
purposes.
In
reliance
upon
these
communications
from
the
Department
of
National
Revenue,
Mr.
Goldstein
filed
his
returns
for
1990
and
1991
upon
the
premise
that
the
losses
sustained
as
a
partner
in
the
limited
partnerships
were
not
to
be
taken
into
account
in
determining
his
earned
income
under
section
146
for
the
purposes
of
determining
how
much
he
could
deduct
as
a
contribution
to
his
RRSP.
Before
the
end
of
1991
he
was
informed
that
the
Department’s
interpretation
had
changed
and
that
under
its
new
interpretation
of
section
146
it
required,
in
the
computation
of
earned
income,
the
deduction
of
losses
sustained
as
a
partner
in
a
limited
partnership
which
derived
its
income
or
loss
from
the
rental
of
MURBs.
The
Minister
assessed
Mr.
Goldstein’s
1989,
1990,
1991
and
1992
taxation
years
accordingly.
The
1989
and
1990
taxation
years
are
not
before
me.
They
were
disposed
of
on
consent,
the
terms
of
which
are
not
relevant
here.
Before
the
time
the
appellant’s
1992
return
was
filed
he
was
aware
that
the
Department
had
changed
its
mind
and
therefore
did
not
rely
upon
the
earlier
position.
The
question
of
estoppel
is,
however,
squarely
before
me
for
1991.1
find
as
a
fact
that
for
that
year
Mr.
Goldstein
clearly
relied
to
his
detriment
upon
a
representation
made
to
him,
through
his
accountants,
by
the
Department
about
their
administrative
practice
and
upon
the
interpretation
of
section
146
which
they
had
at
that
time.
Analysis
I
shall
deal
first
with
the
question
of
the
correctness
in
law
of
positions
taken
on
the
interpretation
of
paragraph
146(1
)(c).
As
stated,
the
meaning
of
’’earned
income"
is
central.
For
the
purposes
of
section
146
it
is
defined
as
follows,
in
paragraph
146(1
)(c):
146(l)(c)
"earned
income"
of
a
taxpayer
for
a
taxation
year
means
the
amount,
if
any,
by
which
the
aggregate
of
all
amounts
each
of
which
is
(i)
the
taxpayer’s
income
for
a
period
in
the
year
throughout
which
the
taxpayer
was
resident
in
Canada
from
(A)
an
office
or
employment,
determined
without
reference
to
paragraphs
8(1
)(c),
(m)
and
(m.2),
(B)
a
business
carried
on
by
the
taxpayer
either
alone
or
as
a
partner
actively
engaged
in
the
business,
or
(C)
property,
where
such
income
is
derived
from
the
rental
of
real
property
or
from
royalties
in
respect
of
a
work
or
invention
of
which
the
taxpayer
was
the
author
or
inventor,
(ii)
an
amount
included
under
paragraph
56(1
)(b),
(c),
(c.l),
(g)
or
(o)
in
computing
the
taxpayer’s
income
for
a
period
in
the
year
throughout
which
the
taxpayer
was
resident
in
Canada,
(iii)
the
taxpayer’s
income
for
a
period
in
the
year
throughout
which
the
taxpayer
was
not
resident
in
Canada
from
(A)
the
duties
of
an
office
or
employment
performed
by
the
taxpayer
in
Canada,
determined
without
reference
to
paragraphs
8(1
)(c),
(m)
and
(m.2),
or
(B)
a
business
carried
on
by
the
taxpayer
in
Canada,
either
alone
or
as
a
partner
actively
engaged
in
the
business
except
to
the
extent
that
the
income
is
exempt
from
income
tax
in
Canada
by
reason
of
a
provision
contained
in
a
tax
convention
or
agreement
with
another
country
that
has
the
force
of
law
in
Canada,
or
(iv)
in
the
case
of
a
taxpayer
described
in
subsection
115(2),
the
aggregate
that
would
be
determined
under
paragraph
(e)
thereof
in
respect
of
the
taxpayer
for
the
year
if
(A)
that
paragraph
were
read
without
reference
to
subparagraphs
(iii)
and
(iv)
thereof,
and
(B)
subparagraph
(e)(ii)
thereof
were
read
without
any
reference
therein
to
paragraph
56(1
)(n),
except
any
part
thereof
included
in
the
aggregate
determined
under
this
paragraph
by
reason
of
subparagraph
(iii)
or
exempt
from
income
tax
in
Canada
by
reason
of
a
provision
contained
in
a
tax
convention
or
agreement
with
another
country
that
has
the
force
of
law
in
Canada,
exceeds
the
aggregate
of
all
amounts
each
of
which
is
(v)
the
taxpayer’s
loss
for
a
period
in
the
year
throughout
which
the
taxpayer
was
resident
in
Canada
from
(A)
a
business
carried
on
by
the
taxpayer,
either
alone
or
as
a
partner
actively
engaged
in
the
business,
or
(B)
property,
where
such
loss
is
sustained
from
the
rental
of
real
property,
(vi)
an
amount
deductible
under
paragraph
60(b),
(c)
or
(c.l)
in
computing
the
taxpayer’s
income
for
the
year,
or
(vii)
the
taxpayer’s
loss
for
a
period
in
the
year
throughout
which
the
taxpayer
was
not
resident
in
Canada
from
a
business
carried
on
by
the
taxpayer
in
Canada,
either
alone
or
as
a
partner
actively
engaged
in
the
business,
and,
for
the
purposes
of
this
paragraph,
the
income
or
loss
of
a
taxpayer
for
any
period
in
a
taxation
year
is
the
taxpayer’s
income
or
loss
computed
as
though
that
period
were
the
whole
taxation
year.
The
expression
can
be
traced
back
to
the
Income
War
Tax
Act.
For
the
purposes
of
this
case
the
relevant
portion
of
paragraph
146(l)(c)
is
subparagraph
146(l)(c)(v),
which
reads
as
follows:
(v)
the
taxpayer’s
loss
for
a
period
in
the
year
throughout
which
the
taxpayer
was
resident
in
Canada
from
(A)
a
business
carried
on
by
the
taxpayer,
either
alone
or
as
a
partner
actively
engaged
in
the
business,
or
(B)
property,
where
such
loss
is
sustained
from
the
rental
of
real
property.
It
is
obvious
that
clause
A
does
not
apply.
Although
the
appellant
was
admittedly
a
partner
in
a
limited
partnership,
it
cannot
be
said
that
his
losses
were
from
”a
business
carried
on
by
[him]...as
a
partner
actively
engaged
in
the
business".
Even
if
it
can
be
said
that
the
limited
partnerships
carried
on
business,
Mr.
Goldstein
clearly
was
not
a
partner
who
was
"actively
engaged
in
the
business".
This
leaves
only
clause
146(l)(c)(v)(B).
Were
his
losses
from
"property,
where
such
loss
is
sustained
from
the
rental
of
real
property"?
The
question
whether
Mr.
Goldstein’s
loss
is
a
loss
from
property,
where
such
loss
is
sustained
as
a
limited
partner
in
a
partnership
which
has
losses
from
renting
real
property
is
not
susceptible
of
a
ready
answer.
I
can
understand
the
uncertainty
that
prompted
Ernst
&
Young
to
consult
the
departmental
officials.
Mr.
Goldstein
argued
that
his
loss
is
not
from
property
but
rather
from
a
partnership.
I
do
not
think
that
this
is
a
correct
view
of
the
matter.
A
partnership
is
not
a
"source"
of
income
in
the
sense
in
which
that
expression
is
used
in
sections
3
and
4
of
the
Income
Tax
Act.
Partnership
is
a
legal
relationship
that
exists
between
persons
engaged
in
a
commercial
enterprise
in
common.
A
partnership
derives
income
from
a
source
or
sources,
just
as
an
individual
or
a
corporation
does.
It
is
not,
in
itself,
a
source
of
income.
This
does
not,
however,
end
the
analysis.
Since
clause
146(l)(c)(v)(A)
refers
specifically
to
partnerships
in
the
business
of
which
the
taxpayer
is
actively
engaged,
does
this
necessarily
exclude
losses
sustained
by
a
limited
partner
in
a
partnership
where
that
partner’s
involvement
is
purely
passive?
Before
attempting
to
answer
this
question
two
subsidiary
questions
arise:
A.
Is
a
commercial
activity
of
a
partnership
necessarily
always
a
source
of
income
that
is
a
business
or
can
it
be
property?
B.
Assuming
the
source
referred
to
in
question
(a)
above
can
be
property,
does
the
interposition
of
a
partnership
between
the
taxpayer
and
the
rental
operation
necessarily
exclude
the
operation
of
clause
146(l)(c)(v)(B)?
As
to
the
first
question,
Mr.
Goldstein
stated
that
he
thought
the
partnerships
were
formed
under
the
law
of
either
Manitoba
or
Alberta.
Assuming
this
to
be
correct,
the
definition
of
partnership
in
the
partnership
acts
of
both
provinces
is
essentially
the
same:
the
relationship
that
subsists
between
persons
carrying
on
business
in
common
with
a
view
to
profit.
If
it
is
suggested
that
one
is
to
conclude
that
the
use
of
the
word
"business”
in
the
definition
of
partnership
in
a
provincial
partnership
act
means
that
a
partnership’s
source
of
income
cannot,
for
the
purposes
of
the
Canadian
Income
Tax
Act,
be
property,
as
opposed
to
a
business,
then
I
think
that
this
conclusion
ascribes
to
a
definition
in
a
provincial
statute
an
effect
that
goes
beyond
its
purpose.
I
accept
that
for
a
partnership
to
exist
for
the
purposes
of
the
Income
Tax
Act
it
must
be
one
that
is
valid
under
the
applicable
civil
law
to
which
the
partnership
is
subject.
It
does
not
follow
that
the
words
in
the
federal
act
must
necessarily
have
the
same
meaning
as
in
the
provincial
act,
or
vice
versa.
The
result,
in
my
view,
is
that:
I.
a
source
of
income
that
is
property
if
owned
by
one
person
does
not
become
a
business
merely
because
it
is
owned
by
a
partnership;
and
II.
even
if
any
commercial
pursuit
of
a
partnership
must
be
characterized
as
the
carrying
on
of
a
business,
there
is
no
reason
why
that
business
cannot
consist
in
the
holding
of
property
for
the
purpose
of
deriving
rental
income
therefrom.
While
there
may
be
cases
in
which
it
is
necessary
to
decide
whether
a
source
of
income
is
business
and
not
property,
or
vice
versa
there
is
no
reason
in
principle
for
assuming
that
the
two
concepts
are
mutually
exclusive
or
that
they
exist
in
watertight
compartments.
As
to
the
second
question,
relating
to
the
interposition
of
a
partnership,
I
think
that,
whether
or
not
the
partnerships
can
be
regarded
as
’’carrying
on
business",
their
losses
were
from
property
and
that
those
losses
were
sustained
from
the
rental
of
property.
Were
they
then
the
appellant’s
losses
from
that
source?
I
think
they
were.
Subsection
96(
1
)
of
the
Income
Tax
Act
reads,
so
far
as
is
relevant
to
this
case,
as
follows:
96(1)
Where
a
taxpayer
is
member
of
a
partnership,
his
income,
non-capital
loss,
net
capital
loss,
restricted
farm
loss
and
farm
loss,
if
any,
for
a
taxation
year,
or
his
taxable
income
earned
in
Canada
for
a
taxation
year,
as
the
case
may
be,
shall
be
computed
as
if
(a)
the
partnership
were
a
separate
person
resident
in
Canada;
(b)
the
taxation
year
of
the
partnership
were
its
fiscal
period;
(c)
each
partnership
activity
(including
the
ownership
of
property)
were
carried
on
by
the
partnership
as
a
separate
person,
and
a
computation
were
made
of
the
amount
of
(i)
each
taxable
capital
gain
and
allowable
capital
loss
of
the
partnership
from
the
disposition
of
property,
and
(ii)
each
income
and
loss
of
the
partnership
from
each
other
source
or
from
sources
in
a
particular
place,
for
each
taxation
year
of
the
partnership;
(f)
the
amount
of
the
income
of
the
partnership
for
a
taxation
year
from
any
source
or
from
sources
in
a
particular
place
were
the
income
of
the
taxpayer
from
that
source
or
from
sources
in
that
particular
place,
as
the
case
may
be,
for
the
taxation
year
of
the
taxpayer
in
which
the
partnership’s
taxation
year
ends,
to
the
extent
to
the
taxpayer’s
share
thereof;
and
(g)
the
amount,
if
any,
by
which
(i)
the
loss
of
the
partnership
for
a
taxation
year
from
any
source
or
sources
in
a
particular
place,
exceeds
were
the
loss
of
the
taxpayer
from
that
source
or
from
sources
in
that
particular
place,
as
the
case
may
be,
for
the
taxation
year
of
the
taxpayer
in
which
the
partnership’s
taxation
year
ends,
to
the
extent
of
the
taxpayer’s
share
thereof.
Although
it
was
probably
not
necessary
to
say
so,
it
is
quite
clear
from
subsection
96(1)
that
the
sources
of
income
or
loss
of
a
partnership
are,
when
that
income
or
loss
is
allocated
to
a
partner,
the
sources
of
income
or
loss
of
the
partner.
The
sources
of
income
or
loss
retain
their
identity
when
allocated
to
the
partner.
The
partnership,
which,
after
all,
is
not
a
legal
entity,
does
not
operate
as
some
kind
of
filter
that
transforms
the
source
of
the
income
or
loss
into
something
other
than
that
which
it
was
originally.
This
interpretation
fits
more
precisely
with
what
appears
to
me
to
be
the
scheme
and
object
of
the
definition
of
“earned
income"
in
section
146.
The
purpose
of
that
definition
appears
to
be
to
exclude
from
it
certain
types
of
passive
income
such
as
interest
and
dividends,
but
not
rental
income
which
may
also
be
passive.
To
interpret
the
definition
as
including
losses
from
a
direct
interest
in
a
MURB,
but
not
one
held
through
a
partnership
would
seem
an
unduly
mechanical
one,
and
one
which
would
lead
to
an
absurdity.

Accordingly
I
think
that
the
Minister’s
interpretation
is
correct
and
the
losses
which
the
appellant
sustained
are
to
be
deducted
in
computing
his
"earned
income"
for
the
purposes
of
section
146.
I
come
next
to
the
question
of
estoppel.
There
is
much
authority
relating
to
the
question
of
estoppel
in
tax
matters
and
no
useful
purpose
would
be
served
by
yet
another
review
of
the
cases.
I
shall
endeavour
however
to
set
out
the
principles
as
I
understand
them,
at
least
to
the
extent
that
they
are
relevant.
Estoppels
come
in
various
forms-estoppel
in
pais,
estoppel
by
record
and
estoppel
by
deed.
In
some
cases
reference
is
made
to
a
concept
of
"equitable
estoppel",
a
phrase
which
may
or
may
not
be
accurate.

Railway

The

It
is
sufficient
to
say
that
the
only
type
of
estoppel
with
which
we
are
concerned
here
is
estoppel
in
pais.

set
out
the
factors
giving
rise
to
an
estoppel
as
follows:
The
essential
factors
giving
rise
to
an
estoppel
are
I
think:
(1)
A
representation
or
conduct
amounting
to
a
representation
intended
to
induce
a
course
of
conduct
on
the
part
of
the
person
to
whom
the
representation
is
made.
(2)
An
act
or
omission
resulting
from
the
representation,
whether
actual
or
by
conduct,
by
the
person
to
whom
the
representation
is
made.
(3)
Detriment
to
such
person
as
a
consequence
of
the
act
or
omission.
Estoppel
is
no
longer
merely
a
rule
of
evidence.
It
is
a
rule
of
substantive
law.”
Lord
Denning
calls
it
"a
principle
of
justice
and
of
equity".
(See
Moorgate
Mercantile
Co.
v.
Twitchings,
[1976]
1
Q.B.
225,
at
page
241.)
It
is
sometimes
said
that
estoppel
does
not
lie
against
the
Crown.
The
statement
is
not
accurate
and
seems
to
stem
from
a
misapplication
of
the
term
estoppel.
The
principle
of
estoppel
binds
the
Crown,
as
do
other
principles
of
law.
Estoppel
in
pais,
as
it
applies
to
the
Crown,
involves
representations
of
fact
made
by
officials
of
the
Crown
and
relied
and
acted
on
by
the
subject
to
his
or
her
detriment.
The
doctrine
has
no
application
where
a
particular
interpretation
of
a
statute
has
been
communicated
to
a
subject
by
an
official
of
the
government,
relied
upon
by
that
subject
to
his
or
her
detriment
and
then
withdrawn
or
changed
by
the
government.
In
such
a
case
a
taxpayer
sometimes
seeks
to
invoke
the
doctrine
of
estoppel.
It
is
inappropriate
to
do
so
not
because
such
representations
give
rise
to
an
estoppel
that
does
not
bind
the
Crown,
but
rather,
because
no
estoppel
can
arise
where
such
representations
are
not
in
accordance
with
the
law.
Although
estoppel
is
now
a
principle
of
substantive
law
it
had
its
origins
in
the
law
of
evidence
and
as
such
relates
to
representations
of
fact.
It
has
no
role
to
play
where
questions
of
interpretation
of
the
law
are
involved,
because
estoppels
cannot
override
the
law.
The
question
of
the
interpretation
of
paragraph
146(l)(c)
is
a
matter
of
law
and
I
must
decide
it
in
accordance
with
the
law
as
I
understand
it.
I
cannot
avoid
that
obligation
because
the
Department
of
National
Revenue
may
previously
have
adopted
an
interpretation
different
from
that
which
it
now
propounds.
The
question
is
not
whether
the
Crown
is
bound
by
an
earlier
interpretation
upon
which
a
taxpayer
has
relied.
It
is
more
to
the
point
to
say
that
the
courts,
who
have
an
obligation
to
decide
cases
in
accordance
with
the
law,
are
not
bound
by
representations,
opinions
or
admissions
on
the
law
expressed
or
made
by
the
parties.
The
result
of
the
application
of
the
rule
in
Maritime
Electric
and
the
many
other
cases
to
the
same
effect
can
have,
in
particular
cases,
unfortunate
consequences
for
a
taxpayer
who,
in
good
faith,
relies
upon
a
departmental
interpretation
that
is
subsequently
changed.
Nonetheless
it
is
not
in
the
interests
of
justice
that
the
courts
should
be
fettered
by
erroneous
interpretations
of
the
law
by
departmental
officials.
The
appeal
is
dismissed.
Appeal
