The
appellant
Shell
Canada
seeks
a
ruling
that
the
respondent,
having
failed
to
seek
leave
to
cross-appeal
under
Rule
29
of
the
Rules
of
the
Supreme
Court
of
Canada
(the
“Rules”),
is
precluded
from
attacking
the
finding
of
the
Court
of
Appeal
that
the
“gain”
realized
in
a
New
Zealand
-
United
States
currency
transaction
entered
into
by
the
appellant
is
a
capital
gain.
This
appeal
concerns
the
proper
tax
treatment
of
a
sophisticated
financing
transaction,
known
as
a
“weak
currency
financing
scheme”,
undertaken
by
the
appellant.
In
1988,
the
appellant
required
about
$100
million
(U.S.)
for
general
corporate
purposes.
The
market
rate
for
a
direct
borrowing
of
U.S.
dollars
was
9.1%.
Instead
of
borrowing
U.S.
dollars
directly,
however,
the
appellant
entered
into
two
agreements.
The
first
agreement
(the
“Borrowing
Contract”),
involved
the
appellant
borrowing
$150
million
(N.Z.)
at
an
interest
rate
of
15.4%
per
annum
(which
was
found
to
be
the
market
rate
for
borrowing
New
Zealand
dollars).
The
second
agreement
(the
“Purchasing
Contract”),
involved
the
appellant
using
the
New
Zealand
funds
to
purchase
$100
million
U.S.
dollars
at
the
market
price.
In
order
to
fulfill
the
appellant’s
requirement
for
New
Zealand
dollars,
the
Purchasing
Contract
provided
for
the
appellant
to
purchase
enough
New
Zealand
dollars
to
satisfy
the
interest
payments
under
the
Borrowing
Contract
and
for
the
appellant
to
purchase
$150
million
(N.Z.)
for
$79
million
(U.S.)
on
the
date
when
the
principle
came
due
under
the
Borrowing
Contract.
The
difference
in
the
cost
of
the
$150
million
(N.Z.)
at
the
time
the
Borrowing
Contract
was
entered
($100
million
(U.S.))
and
at
the
time
the
principle
was
to
be
repaid
($79
million
(U.S.))
resulted
in
a
$21
million
(U.S.)
“gain”
to
the
appellant.
In
computing
its
tax
liability,
the
appellant
deducted
the
15.4%
interest
it
had
paid
under
the
Borrowing
Contract
and
characterized
the
$21
million
(U.S.)
gain
as
a
capital
gain.
The
respondent
reassessed
the
appellant
by
allowing
only
the
cost
of
directly
borrowing
U.S.
dollars
(9.1%)
as
an
interest
expense
and
characterized
the
“gain”
as
income.
The
appellant
appealed
to
the
Tax
Court
where
the
court
found
in
favour
of
the
appellant
and
allowed
the
full
15.4%
to
be
deducted
as
an
expense.
The
Tax
Court
also
characterized
the
gain
as
a
capital
gain.
The
Court
of
Appeal
reversed
the
Tax
Court’s
finding
with
respect
to
the
interest
deduction
applying
an
“economic
substance
over
form”
doctrine
which
essentially
dictated
that
the
Borrowing
Contract
and
Purchasing
Contract
be
considered
together.
This
in
turn
led
the
Court
of
Appeal
to
a
determination
that
the
15.4%
interest
rate
expense
claimed
failed
to
comply
with
three
of
the
requirements
that
must
be
satisfied
for
a
claimed
expense
to
qualify
as
“interest”
under
the
Income
Tax
Act:
it
was
not
interest,
it
was
not
used
for
the
purpose
of
earning
income
and
it
was
not
reasonable.
Therefore,
the
Court
of
Appeal
disallowed
any
interest
expense
claimed
above
9.1%
-
the
direct
cost
of
borrowing
U.S.
dollars.
It
is
on
that
issue
that
the
appellant
sought
and
obtained
leave
to
appeal
in
this
Court.
The
Court
of
Appeal
did,
however,
agree
with
the
Tax
Court
that
the
gain
of
$21
million
(U.S.)
should
be
considered
a
capital
gain.
The
respondent
has
indicated
that
it
intends
to
keep
that
issue
alive
on
the
appeal
to
this
Court.
The
appellant
disputes
the
respondent’s
right
to
do
so.
Rule
29
provides
as
follows:
29.
(1)
A
respondent
who
seeks
to
set
aside
or
vary
the
whole
or
any
part
of
the
disposition
of
the
judgment
appealed
from
shall
apply
for
leave
to
cross-appeal
within
30
clear
days
after
the
service
of
the
application
for
leave,
in
the
case
of
an
appeal
for
which
leave
is
required,
or
30
clear
days
after
the
service
of
the
notice
of
appeal,
in
all
other
cases.
(3)
A
respondent
who
seeks
to
uphold
the
judgment
on
a
ground
or
grounds
not
raised
in
the
reasons
for
the
judgment
appealed
from
may
do
so
in
the
respondent’s
factum
without
applying
for
leave
to
crossappeal,
and
the
appellant
may
serve
and
file
a
factum
in
reply
in
accordance
with
Rule
41.
(emphasis
added)
The
gist
of
the
Rule
is
that
where
a
respondent
wishes
to
vary
the
judgment
appealed
from,
that
respondent
must
apply
for
leave
to
cross-appeal
that
part
of
the
judgment.
Where,
however,
the
respondent
seeks
to
uphold
the
judgment
of
the
lower
court
on
a
ground
not
raised
in
the
reasons
of
the
judgment
appealed
from,
no
leave
to
cross-appeal
is
required.
R.
v.
Keeg-
stra,
[1995]
2
S.C.R.
381
(S.C.C.),
at
400.
The
respondent’s
argument
on
the
capital
gain
issue
would
not,
if
accepted,
uphold
the
judgment
of
the
Court
of
Appeal.
According
to
that
judgment,
the
appellant
may
claim
an
interest
expense
of
9.1%
per
annum
on
the
principal
amount
borrowed
under
the
Borrowing
Contract
in
the
computation
of
its
taxable
income.
The
respondent
says
that
if
the
appeal
against
that
ruling
succeeds,
the
respondent
ought
to
be
free
to
argue
that
the
tax
burden
thus
reduced
should
nevertheless
be
restored
in
whole
or
in
part
by
recharacterizing
the
gain
on
the
Borrowing
Contract
as
income
rather
than
capital.
In
my
view,
the
respondent
would
be
required
to
obtain
leave
to
cross
appeal
before
raising
this
issue
at
the
hearing
of
the
appeal.
In
the
first
place
the
judgment
of
the
Federal
Court
of
Appeal
dated
February
18,
1998
refers
the
matter
back
to
the
Minister
“to
be
reassessed
in
accordance
with
Reasons
for
judgment
herein”.
The
Minister’s
authority
is
thus
closely
circumscribed
by
the
reasons
as
well
as
the
outcome
of
the
appeal
to
that
court.
Secondly,
there
is
no
reason
to
believe
(and
the
respondent
has
not
offered
any
proof)
that
the
net
effect
of
reclassifying
the
$21
million
gain
as
income
would
be
the
same
as
the
net
effect
on
the
appellant’s
tax
burden
of
the
reasons
for
judgment
of
the
Court
of
Appeal.
If
the
tax
burden
calculated
under
the
respondent’s
alternative
argument
differs
from
the
tax
burden
calculated
under
the
Court
of
Appeal’s
judgment,
then
recharacterizing
the
gain
as
income
rather
than
capital
would
not
uphold
even
the
outcome,
much
less
the
reasons
for
judgment
of
the
Federal
Court
of
Appeal.
Accordingly,
if
the
respondent
wishes
to
keep
the
capital
gains
issue
alive
in
this
Court,
she
cannot
do
so
without
leave.
The
proper
procedure
would
be
to
now
serve
and
provide
the
Court
with
the
proposed
leave
application
with
respect
to
the
cross-appeal,
accompanied
by
an
application
for
an
extension
of
time
within
which
to
file
same,
as
set
out
in
the
Notice
to
the
Profession
dated
January,
1996.
The
leave
panel
may
then
determine
whether
it
is
appropriate
to
have
all
aspects
of
the
“weak
currency
financing
scheme”
before
the
Court
on
the
main
appeal.
Order
accordingly.
