Mahoney,
J.A.:—This
application
for
judicial
review
and
a
parallel
one
by
the
applicant's
wife,
file
A-984-92,
are
concerned
with
appeals
against
their
1986
and
1987
income
tax
assessments
dealt
with
together
by
the
Tax
Court
of
Canada
under
its
informal
procedures
as
they
elected
under
section
18
of
the
Tax
Court
of
Canada
Act,
S.C.
1988,
c.
51,
section
5.
The
procedure,
as
it
is
relevant
to
this
application,
is
defined
by
subsection
18.15(4).
Notwithstanding
the
provisions
of
the
Act
out
of
which
an
appeal
arises,
the
Court,
in
hearing
an
appeal
referred
to
in
section
18,
is
not
bound
by
any
legal
or
technical
rules
of
evidence
in
conducting
a
hearing
for
the
purposes
of
that
Act,
and
all
appeals
referred
to
in
section
18
shall
be
dealt
with
by
the
Court
as
informally
and
expeditiously
as
the
circumstances
and
considerations
of
fairness
permit.
The
applicant
applied
to
amend
his
application
record
by
adding
the
transcript
of
the
Tax
Court
hearing
and
the
affidavit
of
George
Valenti,
an
accountant,
who
had
been
his
counsel
at
the
hearing
and
had
been
refused
the
opportunity
to
testify.
The
affidavit
is
directed
to
two
discrete
subjects.
Paragraphs
1
to
4
deal
with
the
refusal
to
hear
his
evidence
and
the
balance
outlines
the
evidence
he
would
have
given
had
he
been
permitted.
The
application
to
add
the
transcript
and
paragraphs
1
to
4
was
allowed
when
the
matter
came
before
the
Court
on
December
13
and
the
matter
was
then
adjourned
until
this
morning
to
permit
the
respondent's
counsel
to
consider
her
position.
Having
had
that
opportunity,
she
now
consents
to
the
judgment
we
propose.
We
feel,
nevertheless,
that
it
would
be
useful
to
indicate
the
grounds
upon
which
that
consent
is,
in
our
view,
entirely
justified.
It
will
not
be
necessary
to
refer
to
the
affidavit.
At
the
outset
of
the
hearing,
when
Valenti
sought
to
outline
the
applicant's
case,
the
following
exchange
occurred
(transcript,
page
2,
I.
2-16):
MR.
VALENTI:
Your
honour,
I
am
appearing
here
today
as
an
agent
and
also
as
a
friend
who
has
intimate
knowledge
of
the
assessments
and
their
business
affairs
over
the
years.
In
fact,
I
was
involved
many
years
ago—I
was
an
accountant
and
I
was
involved
to
some
extent
with
the
preparation
of
the
year-end
financial
statements
for
those
two
years,
1986
and
1987,
with
Price
Waterhouse.
There
are
several
issues
here
that
I
would
like
to
bring
out.
In
the
1986
taxation
year
there
was
a
meeting—
HIS
HONOUR:
Well,
no,
you
mustn't
get
into
testifying
as
to
facts.
You
are
here
as
agent
or
counsel
for
these
people.
The
hearing
proceeded
directly
to
receive
the
evidence
of
the
applicant
and
his
wife.
It
appeared
during
examination,
cross-examination
and
reexamination
that
neither
had
much
understanding
of
the
financial
statements.
Valenti's
efforts
to
lead
them
were
forestalled
by
the
judge.
When
their
testimony
was
concluded
the
following
transpired
(transcript,
page
80,
I.
1
to
page
81,
I.
19):
HIS
HONOUR:
I
take
it,
Mr.
Valenti,
you
have
no
other
witnesses
to
call?
MR.
VALENTI:
No,
I
don't.
Can
I
call
myself
as
a
witness?
HIS
HONOUR:
Why
would
you
call
yourself
as
a
witness?
You're
going
to
have
an
opportunity
to
argue
from
the
facts
that
have
been
adduced
here
today.
MR.
VALENTI:
Will
it
have
the
same
force
as
being
a
witness?
HIS
HONOUR:
Normally,
a
person
doesn't
come
in
and
act
as
both
counsel
and
a
witness.
MR.
VALENTI:
I
realize
that.
This
is
an
unusual
situation.
HIS
HONOUR:
What
is
unusual
about
it?
MR.
VALENTI:
The
reason
that
I
would
like
to
give
some
evidence
is
because
they
perhaps
don’t
understand
financial
statements.
They
perhaps
didn't
state
their
case
too
clearly
about
what
changes
they
had
made
to
the
company
after
their
attention
was
drawn
to
the
inadequacies
of
the
records
and
books
that
were
kept.
HIS
HONOUR:
What
do
you
say
about
it?
MR.
FORER:
I
would
object
to
an
agent
being
called
as
a
witness
when
he's
carried
the
case
throughout.
It’s
certainly
prejudicial
to
the
Minister
to
have
to
now,
while
we
sat
here
and
found
there
were
failings
in
their
case
from
direct
testimony,
to
be
able
to
stand
up
and
clarify
anything
that
they
have
personal
knowledge
of,
and
1
have
yet
to
hear
whether
he
has
any
personal
knowledge
of
it
as
well.
HIS
HONOUR:
I
am
not
going
to
allow
you
to
testify.
Finally,
as
he
was
about
to
present
his
argument,
Valenti
was
instructed
(transcript,
page
117,
I.
16-21):
HIS
HONOUR:
We
are
coming
to
argument
now.
You
lead
[sic]
and
argue
from
the
facts
that
have
been
placed
before
me
here
this
morning.
Don’t
inject
your
personal
knowledge
of
the
case.
Don't
act
as
a
witness,
in
other
words.
Act
as
an
advocate
arguing
from
a
set
of
facts.
The
initial
instruction
that
the
facts
had
to
be
established
by
evidence
under
oath
is
unexceptionable.
So
is
the
final
instruction
that
argument
ought
to
be
based
on
the
facts
so
proved.
However,
barring
Valenti,
as
counsel,
from
making
an
opening
statement
was
by
no
means
right
and
the
refusal
to
let
him
testify
was
clearly
wrong.
The
credibility
of
every
witness
is
in
issue.
That
a
member
of
the
bar
acting
as
counsel
in
a
proceeding
be
not
allowed
to
testify
is
a
requirement
of
the
due
administration
of
justice.
Such
counsel
is
an
officer
of
the
Court
whose
credibility
is
accepted
without
qualification.
That
credibility
must
not
be
put
in
issue
by
counsel
giving
evidence.
For
an
officer
of
the
Court,
the
functions
of
counsel
and
witness
in
the
same
cause
are
simply
incompatible
and
not
to
be
tolerated.
Lay
counsel,
when
required
or
permitted
to
be
heard
as
in
the
subject
Tax
Court
proceeding,
is
not
an
officer
of
the
Court.
The
objection
of
the
respondent's
counsel,
assuming
it
to
have
been
a
factor
in
the
ruling,
was
based
on
pure
speculation.
The
prejudice,
if
any,
which
might
have
resulted
from
Valenti’s
testimony
was
something
to
be
dealt
with
once
it
had
been
heard,
not
by
refusing
to
hear
it.
We
are
all
of
the
opinion
that
the
exclusion
of
Valenti’s
evidence
denied
the
applicant
the
opportunity
fully
to
present
his
case,
that
there
were
no
circumstances
peculiar
to
this
proceeding
that
justified
that
denial
and
that
the
approach
taken
throughout
by
the
learned
Tax
Court
judge
was
contrary
to
the
direction
for
the
conduct
of
informal
hearings
Parliament
has
given
that
Court
by
subsection
18.15(4)
of
its
constituting
Act.
The
appeal
was
not,
in
our
view,
conducted
in
accordance
with
the
dictates
of
natural
justice
nor
of
the
Act.
The
decisions
of
the
Tax
Court
of
Canada
rendered
July
8,
1992,
under
its
files
92-599
and
92-600
will
be
set
aside
and
both
appeals
remitted
for
a
new
hearing
by
a
different
judge.
Application
allowed.
