Denault,
J.:—
This
is
an
appeal
pursuant
to
Rule
336(5)
of
the
Federal
Court
Rules
by
the
defendant
from
the
order
of
the
Associate
Senior
Prothonotary
Giles
dated
April
19,
1993,
granting
leave
to
the
plaintiffs
to
file
an
amended
statement
of
claim.
The
grounds
for
appeal
are
that
the
decision
was
wrong
and
that
the
decision
involves
a
question
vital
to
the
final
issue
of
the
case.
The
defendant
is
seeking
to
have
the
decision
set
aside
and
requesting
that
I
exercise
discretion
de
novo
in
determining
whether
leave
to
amend
the
statement
of
claim
should
be
granted.
The
main
action
involves
an
appeal
by
the
plaintiffs
of
notices
of
assessment
for
the
1984
and
1985
taxation
years.
The
principal
issue
in
the
original
statement
of
claim
was
whether
the
plaintiffs
are
entitled
to
a
Part
VIII
refund
on
the
basis
that
a
number
of
expenditures
constituted
scientific
research
and
experimental
development
expenditures
within
the
meaning
of
subsection
37(1)
and
subsection
194(2)
of
the
Income
Tax
Act,
R.S.C.
1952,
c.
148
(am.
S.C.
1970-71-72,
c.
63)
(the
"Act").
The
decision
of
the
Associate
Senior
Prothonotary
granted
leave
to
the
plaintiffs
to
amend
the
original
statement
of
claim
to
raise
the
issue
of
the
validity
of
a
number
of
designations
made
by
the
plaintiffs
during
the
1985
taxation
year
pursuant
to
subsection
194(4)
of
the
Act.
The
Minister’s
principal
objections
to
these
amendments
are
that
they
effectively
withdraw
admissions
made
in
the
original
statement
of
claim
and
reply,
that
they
raise
a
completely
new
cause
of
action
and
that
they
will
prejudice
the
defendant
in
a
manner
not
compensable
in
costs.
Facts
The
following
is
a
summary
of
the
facts
in
relation
to
the
1985
taxation
year
only.
Counsel
for
both
parties
agreed
at
the
hearing
to
the
proposed
amendment
adding
a
preliminary
paragraph
to
the
statement
of
claim
limiting
the
action
to
an
appeal
of
the
assessment
for
the
1985
taxation
year.
Therefore,
it
is
not
necessary
to
examine
here
the
details
of
the
1984
taxation
year.
The
plaintiff,
Orenstein
&
Partners
Inc.
(Orenstein),
is
the
Court-appointed
receiver
of
the
Part
VIII
tax
refund
allegedly
owing
to
the
other
plaintiff,
Scannar
Industries
Inc.
(Scannar).
Scannar's
1985
taxation
year
began
on
December
1,
1984
and
ended
on
November
30,
1985.
On
November
15
1984,
counsel
for
Scannar
wrote
to
the
Minister
of
National
Revenue
(Minister)
requesting
an
opinion
on
whether
a
proposed
transaction
with
Combustion
Engineering
Superheater
Ltd.
would
fulfil
the
requirements
of
Part
VIII
of
the
Income
Tax
Act,
in
particular
whether
a
designation
made
pursuant
to
subsection
194(4)
of
an
investment
by
Combustion
Engineering
Superheater
Ltd.
would
meet
the
criteria
in
subsection
194(4.2)
regarding
designations
made
after
October
10,
1984.
Part
VIII
of
the
Income
Tax
Act
provides
the
structure
for
a
deduction
from
business
income
for
scientific
research
and
experimental
development
expendi
tures
when
third
parties
have
invested
in
the
corporation
and
are
going
to
claim
the
scientific
research
and
experimental
development
credit
in
section
127.3.
When
a
corporation
has
designated
the
investors
and
amounts
received
under
subsection
194(4),
the
corporation
incurs
tax
liability
pursuant
to
subsection
194(1)
for
50
per
cent
of
the
total
amount
designated.
Subsection
194(4.2)
was
enacted
to
limit
the
application
of
subsection
194(4)
to
designations
made
prior
to
October
10,
1984.
However,
paragraph
194(4.2)(b)
allows
certain
designations
made
after
October
10,
1984
to
be
“grandfathered”
into
the
application
of
Part
VIII
if
they
meet
specific
criteria.
Subsection
194(2)
permits
a
reduction
of
the
corporation's
tax
liability
incurred
by
the
designations
in
the
amount
of
50
per
cent
of
the
total
scientific
research
and
experimental
development
expenditures
of
the
corporation
in
the
taxation
year
which
meet
the
criteria
in
paragraphs
37(1
)(a)
and
(b).
That
portion
of
the
latter
amount
which
exceeds
the
tax
liability
incurred
by
the
designations
is
refundable
pursuant
to
subsection
194(3).
On
December
3,
1984,
the
Minister
responded
that
the
proposed
transaction
with
Combustion
Engineering
Superheater
Ltd.
would
satisfy
the
necessary
requirements
of
paragraph
194(4.2)(b).
On
December
31,
1984,
Scanner
filed
three
designations
pursuant
to
subsection
194(4)
of
the
Act:
$19,000,00
for
Hayes-Dana
Inc.,
$5,000,000
for
Chieftain
Products
Inc.,
and
$1,000,000
for
Atelco
Inc.
On
January
11,
1985,
a
designation
was
filed
in
respect
of
shares
issued
to
employees
in
the
amount
of
$101,000.
Finally,
on
January
25,
1985,
$5,000,000
was
designated
in
respect
of
the
above-
mentioned
transaction
with
Combustion
Engineering
Superheater
Ltd.
The
total
of
these
designations
was
$30,101,000.
On
December
2,
1985,
Scannar
filed
its
Part
VIII
tax
return
and
reported
that
50
per
cent
of
the
designated
amounts
was
$15,055,500
(the
amount
should
have
been
$15,050,500).
This
represents
Scannar’s
Part
VIII
tax
liability
pursuant
to
subsection
194(1).
The
third
parties
to
whom
the
shares
or
debt
obligations
subject
to
the
designations
were
issued
were
entitled
to
claim
tax
credits
equal
to
50
per
cent
of
the
amount
(these
credits
were
claimed
by
Hayes-Dana
Inc.,
Combustion
Engineering
Superheater
Ltd.
and
Chieftain
Products
in
their
returns).
In
its
return,
Scannar
also
indicated
that
it
paid
to
the
Receiver
General
$8,700,000
on
account
of
the
tax
liability
arising
from
the
designations.
Finally,
Scannar
indicated
that
it
incurred
a
total
of
$27,869,383
in
scientific
research
expenditures
pursuant
to
subsection
37(1)
of
the
Act.
This
amount
includes
$25,000,000
resulting
from
a
contract
dated
November
27,
1985
with
Proteus
Bio-Research
Corporation
to
provide
research
and
development
services
in
connection
with
the
production
of
certain
products.
As
a
result,
Scannar
claimed
a
Part
VIII
refund
of
$8,837,761.
By
notice
of
assessment
dated
June
8,
1987,
the
Minister
disallowed
$26,579,013
of
the
expenditures,
including
the
Proteus
expenditure.
Taking
into
consideration
the
$8,700,000
payment
and
the
error
in
reporting
the
liability
for
the
designated
amounts,
the
assessment
resulted
in
a
total
Part
VIII
tax
liability
on
the
part
of
Scannar
for
the
1985
taxation
year
in
the
amount
of
$4,405,316.50.
On
September
1,
1987
Scannar
filed
a
Notice
of
Objection.
The
assessment
was
confirmed
by
the
Minister
on
14
December
1988.
The
plaintiffs
filed
a
statement
of
claim
appealing
this
assessment
on
March
13,
1989.
The
principal
issue
in
the
original
statement
of
claim
was
whether
the
plaintiffs
are
entitled
to
a
Part
VIII
refund
on
the
basis
that
a
number
of
expenditures
constituted
scientific
research
and
experimental
development
expenditures
under
subsection
37(1).
There
is
no
mention
of
the
designations,
though
the
statement
of
claim
states
at
paragraph
9
that
"Scannar
paid
certain
amounts
in
respect
of
Part
VIII
Tax
[sic]
for
the
1984
and
1985
fiscal
years.”
This
statement
of
claim
was
met
by
a
statement
of
defence
in
which,
at
paragraph
12(c),
the
defendant
states:
“in
February
of
1985
Scannar
paid
Part
VIII
tax
in
the
amount
of
$8,700,000.”
In
paragraph
12(d)
the
defendant
states:
.
.
.
in
its
1985
taxation
year,
Scannar
designated
an
amount
pursuant
to
subsection
194(4)
of
the
Income
Tax
Act
of
$30,101,000
thus
creating
Part
VIII
tax
payable
of
$15,050,000.
The
designation
followed
a
"quick
flip"
transaction
whereby
securities
given
by
Scannar
to
investors
were
contemporaneously
redeemed
by
Scannar
at
an
amount
of
approximately
60
per
cent
of
the
face
amount
of
the
securities,
leaving
Scannar
with
cash
of
approximately
40
per
cent
of
the
amount
of
the
designation;
In
paragraph
6
of
its
reply,
"[T]he
plaintiff
denies
the
allegations
in
subparagraph
12(d),
but
states
that
the
amount
designated
pursuant
to
subsection
194(4)
of
the
Income
Tax
Act
in
1985
was
$30,111,000,
thus
creating
Part
VIII
tax
payable
of
$15,055,500.”
In
paragraph
7,
"[T]he
plaintiff
admits
the
allegations
of
fact
in
paragraphs
4
and
12(c),
but
in
addition
the
fact
is
that
the
plaintiff
acquired
scientific
research
tax
credits
in
the
amount
of
$1,300,000,
for
1985.”
By
notice
of
motion
dated
April
8,
1993,
the
plaintiffs
applied
for
leave
to
amend
the
statement
of
claim.
The
principal
amendments
raise
the
issue
regarding
the
validity
of
the
designations
made
pursuant
to
subsection
194(4)
of
the
Act.
On
April
19,
1993,
the
Associate
Senior
Prothonotary
allowed
the
application
without
reasons
and
the
Minister
filed
a
notice
of
motion
on
May
3,
1993
to
appeal
this
decision.
The
motion
was
heard
by
me
on
September
27,
1993.
Issues
As
mentioned
above,
during
the
hearing
on
the
motion
the
Minister
consented
to
proposed
amendments
limiting
the
action
to
an
appeal
of
the
assessment
for
the
1985
taxation
year.
Other
amendments
consented
to
included
those
which
limited
the
action
to
an
appeal
of
the
disallowance
of
the
$25,000,000
expenditure
resulting
from
the
Proteus
contract
and
those
which
“cleaned
up
the
other
points"
to
be
dealt
with.
As
such,
I
will
limit
my
review
of
the
Associate
Senior
Prothonotary's
decision
to
the
proposed
amendments
relating
to
the
validity
of
the
designations
made
pursuant
to
subsection
194(4).
In
my
opinion,
the
first
determination
to
be
made
is
whether
this
is
an
instance
where
I
should
intervene
in
a
discretionary
decision
of
a
prothonotary
and
exercise
my
own
discretion
de
novo.
The
second
issue
involves
a
determination
of
whether
the
proposed
amendments
should
be
allowed.
Standard
of
review
The
standard
of
review
of
a
prothonotary's
order
was
set
out
by
Justice
Mac-
Guigan
in
Aqua-Gem
Investments
Ltd.
v.
M.N.R.,
[1993]
1
C.T.C.
186,
93
D.T.C.
5080,
at
pages
207-08
(D.T.C.
5094),
representing
the
majority
of
the
Federal
Court
of
Appeal
sitting
on
a
bench
of
five
judges,
when
he
stated
that:
.
.
.discretionary
orders
of
prothonotaries
ought
not
to
be
disturbed
on
appeal
to
a
judge
unless:
(a)
they
are
clearly
wrong
in
the
sense
that
the
exercise
of
discretion
by
the
prothonotary
was
based
upon
the
wrong
principle
or
upon
a
misapprehension
of
the
facts,
or
(b)
they
raise
questions
vital
to
the
final
issue
of
the
case.
Where
such
discretionary
orders
are
clearly
wrong
in
that
the
prothonotary
has
fallen
into
error
of
law
(a
concept
in
which
I
include
a
discretion
based
upon
a
wrong
principle
or
upon
a
misapprehension
of
the
facts),
or
where
they
raise
questions
vital
to
the
final
issue
of
the
case,
a
judge
ought
to
exercise
his
own
discretion
de
novo.
On
this
issue,
the
plaintiffs
maintain
that
the
defendant
cannot
establish
that
the
order
allowing
the
amendment
was
based
on
the
application
of
a
wrong
principle
or
a
misapprehension
of
the
facts.
They
also
submit
that
the
order
does
not
determine
any
issue
vital
to
the
final
decision
in
the
case,
"but
rather
is
allowing
the
trial
judge
to
decide
the
action
on
the
basis
of
all
the
facts
of
the
case"
(Plaintiffs’
Outline
of
Argument
on
the
Motion
to
Appeal,
at
paragraph
14).
Counsel
for
the
defendant
argues
the
opposite.
Because
Associate
Senior
Prothonotary
Giles
did
not
provide
any
reasons
for
his
decision
it
is
difficult
to
determine
whether
he
erred
by
applying
a
wrong
principle
or
misapprehending
the
facts
of
the
case.
However,
such
a
determination
is
not
necessary
since
I
am
of
the
opinion
that
the
order
raises
a
question
“vital
to
the
final
issue
of
the
case”.
In
my
opinion,
this
is
a
case
where
the
Court
ought
to
intervene
and
exercise
its
discretion
de
novo
because
the
amendments,
if
allowed,
would
create
a
whole
new
cause
of
action.
Implicit
in
many
of
the
plaintiffs
arguments
in
support
of
the
necessity
for
the
amendment
is
the
view
that
the
amendments
are
necessary
because
they
put
into
issue
the
validity
of
the
designation
and
a
negative
finding
on
this
question
will
relieve
Scannar
from
any
liability
for
the
payment
of
any
Part
VIII
tax
for
the
1985
taxation
year
(Plaintiffs’
Outline,
supra,
paragraph
7).
Clearly,
the
issues
raised
by
the
amendments
are
vital
to
the
final
resolution
of
the
case.
However,
this
does
not
mean
that
the
amendments
should
or
should
not
be
allowed,
merely
that
I
ought
to
examine
the
amendments
and
exercise
my
own
discretion.
The
amendments
Plaintiffs'
submissions
As
stated
above,
the
plaintiffs
argued
that
the
amendments
are
necessary
to
put
in
issue
the
validity
of
the
designations
made
pursuant
to
subsection
194(4)
of
the
Act
in
order
to
enable
the
Court
to
determine
the
validity
of
the
assessment
on
the
basis
of
all
of
the
relevant
facts.
They
submit
that
they
were
previously
unaware
that
the
designations
may
not
be
valid
and
could
not
have
intended
to
concede
this
point.
The
plaintiffs
maintain
that
the
Minister
is
not
prejudiced
by
the
amendments
because,
notwithstanding
the
expiration
of
the
limitation
period
in
subsection
152(4),
the
third
party
investors
could
be
pursued
to
repay
the
scientific
research
and
experimental
development
tax
credit
they
received
as
a
result
of
the
designations
on
the
basis
of
misrepresentation.
Also,
they
maintain
that
the
amendments
cause
no
additional
prejudice
to
the
Minister
in
that
the
limitation
period
had
already
expired
for
some
of
the
third
party
investors
when
the
original
statement
of
claim
was
filed.
If
it
is
shown
that
the
amendments
may
cause
prejudice
to
the
defendant,
it
seems
that
the
plaintiffs
submit
that
this
prejudice
is
compensable
by
costs
and
that
this
prejudice
is
in
part
the
result
of
the
Minister's
failure
to
discharge
its
duty
to
verify
the
designations
when
they
were
made.
On
the
issue
of
whether
the
amendments
constitute
a
withdrawal
of
an
admission,
it
is
the
plaintiffs’
opinion
that
paragraph
7
of
the
statement
of
claim
and
paragraphs
6
and
7
of
the
reply
do
not
constitute
admissions
as
to
the
validity
of
the
designations.
In
their
view,
paragraph
6
is
an
express
denial
of
the
validity
of
all
of
the
allegations
in
paragraph
12(d)
of
the
defence,
including
the
remarks
about
the
designations.
However,
if
the
amendments
are
considered
to
be
a
withdrawal
of
an
admission,
the
plaintiffs
submit
that
the
same
principles
of
law
as
those
governing
any
other
amendment
apply.
In
particular
and
in
addition
to
the
above
arguments
regarding
the
amendments
generally,
they
maintain
that
the
alleged
admission
was
made
inadvertently
and
that
they
acted
promptly
to
remedy
the
error.
Finally,
the
plaintiffs
argue
that
the
decision
of
the
Associate
Senior
Prothonotary
was
based
on
the
view
that
the
defendant's
objections
are
based
on
the
notion
of
estoppel
—
that
is
that
the
plaintiffs
are
estopped
from
relying
on
the
application
of
subsection
194(4.2)
—
and
that
this
is
an
argument
that
should
more
properly
be
considered
by
the
trial
judge
(Plaintiffs’
Outline,
supra,
paragraphs

and

There
is
no
evidence
before
me
other
than
the
Plaintiffs’
Outline
as
to
what
the
reasons
were
for
the
Associate
Senior
Prothonotary's
decision.
However,
it
is
not
necessary
to
consider
the
issue
of
estoppel
to
determine
this
appeal.
Defendant's
submissions
The
defendant's
submissions
are
based
on
the
view
that
the
amendments
constitute
a
withdrawal
of
an
admission.
The
Minister
maintains
that
the
amend-
ments
result
in
severe
prejudice
and
that
this
prejudice
cannot
be
compensated
by
costs.
In
support
of
this
submission,
the
defendant
argues
that
the
designations
were
acted
on
in
good
faith
by
the
Minister
and
that
it
allowed,
as
a
result
of
these
designations,
scientific
research
and
experimental
development
tax
credits
to
be
claimed
by
the
third
party
investors
pursuant
to
section
127.3
in
the
total
amount
of
$14,500,000.
The
Minister
submits
that
the
operation
of
subsection
152(4)
prevents
it
from
reassessing
these
companies
unless
there
is
evidence
of
misrepresentation
attributable
to
neglect,
carelessness
or
wilful
default
or
evidence
of
fraud.
No
such
evidence
was
presented
by
the
plaintiffs
in
support
of
the
motion.
As
such,
if
the
plaintiffs
are
permitted
to
change
their
position
and
succeed
at
trial,
the
Minister
is
left
in
the
position
of
having
lost
the
tax
payable
by
the
third
party
investors
which
was
offset
by
the
tax
credits
and,
at
the
same
time,
of
having
lost
the
Part
VIII
tax
payable
by
the
plaintiffs
as
a
result
of
the
designations.
On
the
issue
of
the
timeliness
of
the
motion,
the
defendant
submits
that
there
is
no
reasonable
explanation
for
the
withdrawal
of
the
admission
and
change
in
position.
It
is
submitted
that
the
explanations
that
the
admission
was
inadvertent,
that
the
plaintiffs
acted
promptly
to
correct
the
error,
and
that
the
plaintiff
Orenstein
was
not
advised
by
its
solicitor
that
the
designations
might
not
be
valid
are
insufficient.
The
defendant
maintains
that
the
plaintiffs
were
aware
of
the
possible
issue
regarding
the
validity
of
the
designation
as
early
as
14
November
1984
when
counsel
for
the
plaintiffs
wrote
to
the
Minister
for
an
opinion
about
the
proposed
Combustion
Engineering
Superheater
Ltd.
transaction.
The
same
firm
filed
the
original
statement
of
claim
and
reply.
Finally,
the
defendant
submits
that
there
is
insufficient
evidence
of
a
triable
issue
to
support
the
amendment.
The
only
evidence
of
the
timing
of
the
transactions
giving
rise
to
the
designations
is
the
aforementioned
opinion
letter
and
the
reply
by
the
Minister,
evidence
which
supports
the
validity
of
the
designations.
It
is
submitted
that
the
allegation
that
Revenue
Canada
officials
accepted
the
designations
without
verifying
or
confirming
them
is
not
sufficient
evidence
raising
a
triable
issue.
Analysis
The
rule
governing
the
amendment
of
pleadings
is
set
out
in
Rule
420(1)
of
the
Federal
Court
Rules:
420.(1)
The
Court
may,
on
such
terms,
if
any,
as
seems
ust,
at
any
stage
of
an
action,
allow
a
party
to
amend
his
pleadings,
and
all
such
amendments
shall
be
made
as
may
be
necessary
for
the
purpose
of
determining
the
real
question
or
questions
in
controversy
between
the
parties.

Court
of
Appeal
considered
similar
amendments
and

at

.

.
the
general
rule
is
that
an
amendment
should
be
allowed
'Tor
the
purpose
of
determining
the
real
questions
in
controversy
between
the
parties”
provided
that
the
allowance
would
not
result
in
an
injustice
to
the
other
party
not
capable
of
being
compensated
by
an
award
of
costs.

The
Tax
Court,
in
Continental
Bank,
applies
the
same
rule
as
set
out
in
Francoeur,
supra,
(adding
the
test
for
a
"triable
issue”)
to
the
specific
situation
where
the
effect
of
the
amendment
is
a
withdrawal
of
an
admission
and
held
(page
2310
(D.T.C.
302))
that
the
question
of
whether
an
amendment
or
a
withdrawal
of
an
admission
should
be
allowed
should
be
put
on
a
broad
basis:
is
the
amendment
in
the
interests
of
justice?
The
Court
states
further
that:
.
.
.
other
factors
should
also
be
emphasized,
including
the
timeliness
of
the
motion
to
amend
or
withdraw,
the
extent
to
which
the
proposed
amendments
would
delay
the
expeditious
trial
of
the
matter,
the
extent
to
which
a
position
taken
originally
by
one
party
has
led
another
party
to
follow
a
course
of
action
in
the
litigation
which
it
would
be
difficult
or
impossible
to
alter
and
whether
the
amendments
sought
will
facilitate
the
court's
consideration
of
the
true
substance
of
the
dispute
on
its
merits.
No
single
factor
predominates
nor
is
its
presence
or
absence
necessarily
determinative.
All
must
be
assigned
their
proper
weight
in
the
context
of
the
particular
case.
Ultimately
it
boils
down
to
a
consideration
of
simple
fairness,
common
sense
and
the
interest
that
the
courts
have
that
justice
be
done.
On
the
basis
of
the
above,
it
would
appear
that
the
considerations
are
the
same
whether
the
amendments
are
considered
to
be
a
withdrawal
of
an
admission
or
not,
though
in
my
opinion
the
proposed
amendments
do
constitute
a
withdrawal
of
the
admission
that
the
designations
were
considered
by
the
plaintiffs
to
be
valid.
These
amendments
would
cause
prejudice
to
the
defendant
because
the
Minister
is
now
precluded
from
reassessing
the
third
party
investors.
The
potential
prejudice
caused,
in
the
amount
of
$14,500,000
representing
the
total
amount
of
credits
claimed
and
allowed
on
the
basis
of
the
designations
and
not
including
interest,
is
clearly
not
compensable
by
costs.
While
it
could
be
argued
that
this
prejudice
is
dependent
upon
the
final
resolution
of
the
case
and
is
not
relevant
to
the
determination
here,
I
am
persuaded
that
when
you
weigh
the
potential
prejudice
along
with
some
of
the
other
factors
to
be
considered
against
the
scarcity
of
the
evidence
presented
with
respect
to
the
merits
of
the
issue
to
be
raised,
the
proposed
amendments
do
not
aid
in
"determining
the
real
questions
in
controversy
between
the
parties”
nor
do
they
raise
a
"triable
issue".
In
addition,
I
am
of
the
opinion
that
counsel
for
the
plaintiffs
had
plenty
of
previous
opportunities
for
raising
the
issue
of
the
validity
of
the
designations
and
that
this
motion
is
by
no
means
"timely".
The
failure
of
the
plaintiffs
to
raise
the
issue
beforehand
has
caused
the
Minister
to
take
a
course
of
action
which
is
impossible
to
alter.
Specifically,
since
the
reply
to
the
opinion
letter
was
provided
and
the
1985
return
filed,
the
Minister
has
acted
on
the
basis
that
the
validity
of
the
designations
and
these
actions
cannot
be
changed
retroactively.
Conclusion
All
of
these
considerations
lead
me
to
conclude
that
the
proposed
amendments
regarding
the
designations
would
cause
an
irremediable
injustice
that
could
not
be
compensated
by
an
award
of
costs.
Accordingly,
the
appeal
must
be
allowed
and
the
order
of
the
Associate
Senior
Prothonotary
dated
April
19,
1993
granting
leave
to
the
plaintiffs
to
file
an
amended
statement
of
claim
is
set
aside.
The
Court
reserves
to
the
plaintiffs
the
right
to
file
a
revised
amended
statement
of
claim
not
incompatible
with
this
order.
Costs
in
the
cause.
Appeal
allowed.
