Plaintiff
raises
a
straightforward
challenge
to
the
denial
of
her
motion
for
a
new
trial
or
evidentiary
hearing.
But
in
presenting
that
challenge,
plaintiff’s
counsel
created
a
separate
problem
by
repeatedly
relying
on
fabricated
and
unsupported
legal
aut
hority.
The
merits
issue
is
easily
resolved.
Plaintiff
sought
a
new
trial
or
evidentiary
hearing
based
on
alleged
juror
misconduct
and
irregularities,
but
the
allegations
depended
on
facts
outside
the
record
and
were
not
supported
by
valid
affidavits.
Even
setting
aside
this
procedural
defect,
plain
tiff
also
failed
to
show
that
any
alleged
irregularity
affected
her
substantial
rights.
The
trial
court
therefore
did
not
abuse
its
discretion
by
denying
relief.
The
briefing
issue
requires
separate
attention.
In
the
trial
court
and
again
on
appeal,
plaintiff’s
counsel
relied
on
artificial
intelligence
without
adequate
verification,
leading
him
to
cite
nonexistent
cases
and
invoke
real
cases
for
propositions
they
do
not
support
,
even
after
defendant
identified
the
defects.
Counsel
later
acknowledged
in
a
“Notice
of
Correction”
that
artificial
intelligence
had
generated
“plausible
but
fabricated
case
citations
—
a
known
limitation
of
such
-
2
-
tools.”
Yet
that
notice,
also
prepared
with
the
assistance
of
artificial
intelligence,
attributed
quotations
and
legal
propositions
to
cases
that
did
not
contain
them.
We
affirm
the
trial
court’s
order
denying
plaintiff’s
motion
for
a
new
trial
or
evidentiary
hearing.
But
because
counsel’s
repeated
submission
of
fabricated
and
unsupported
authority
grossly
disregarded
the
requirements
of
fair
presentation
and
violated
t
he
duty
of
reasonable
inquiry,
we
remand
for
a
determination
of
the
actual
damages
and
expenses
that
defendant
incurred
because
of
this
appeal,
which
shall
be
payable
by
plaintiff’s
counsel
personally.
I.
BACKGROUND
This
case
arises
from
a
hip
replacement
surgery
that
defendant
,
a
n
orthopedic
surgeon,
performed
on
plaintiff
at
Ascension
Providence
Hospital
in
October
2020.
Plaintiff
sued,
asserting
claims
of
medical
malpractice
and
negligence
related
to
the
surgery.
After
a
five
-
day
trial,
the
jury
found
that
defendant
was
not
negligent.
The
trial
court
then
polled
the
jurors
.
Jurors
1,
2,
3,
4,
and
5
confirmed
that
the
verdict
accurately
reflected
their
votes.
Juror
7
,
the
foreperson
,
answered
that
it
did
not
.
Because
five
jurors
agreed,
the
verdict
was
sufficient
in
this
civil
action.
See
MCL
600.1352
;
MCR
2.514(A)
.
After
the
poll,
defense
counsel
asked
whether
the
attorneys
could
speak
with
the
jurors
.
The
trial
court
agreed
to
permit
a
discussion
if
the
jurors
were
willing.
The
court
then
spoke
with
the
jurors
and
participated
in
an
off
-
the
-
record
discussion
with
the
jurors
and
trial
counsel.
Plaintiff
later
moved
for
a
new
trial
or
an
evidentiary
hearing
.
She
alleged
that
the
verdict
was
tainted
by
juror
misconduct,
improper
extraneous
influence
s,
and
irregularities
in
the
deliberative
process.
Specifically,
plaintiff
asserted
that,
during
the
post
-
verdict
discussion
,
one
juror
admitted
consulting
his
mother,
who
had
undergone
hip
surgery,
about
x
-
rays
and
her
opinion
of
the
case;
that
another
juror
admitted
conducting
independent
online
research
about
the
size
of
a
25
-
millimeter
screw;
that
the
foreperson
said
he
wanted
to
review
trial
e
xhibits
further
before
voting
but
other
jurors
prevented
him
from
doing
so;
and
that
alternate
jurors
remained
in
the
jury
room
during
deliberations
and
favored
the
defense.
Plaintiff
relied
primarily
on
criminal
caselaw
and
constitutional
principles,
contending
that
s
he
was
entitled
to
a
new
trial
because
the
verdict
was
“influenced
by
improper
extraneous
evidence
and
a
compromised
deliberation
process.”
To
support
the
factual
assertions
in
the
motion,
plaintiff
purported
to
attach
affidavits
from
her
trial
attorneys.
Those
affidavits,
however,
were
not
notarized.
Defendant
disputed
plaintiff’s
account
of
the
post
-
verdict
discussion
and
supported
his
response
with
notarized
affidavits
from
defense
counsel
.
According
to
defendant,
no
juror
stated
that
he
had
consulted
his
mother
about
x
-
rays
or
evidenc
e
in
the
case;
one
juror
merely
mentioned
that
his
mother
had
previously
undergone
hip
replacement
surgery.
Defendant
also
asserted
that
no
juror
admitted
conducting
independent
research
regarding
the
screw
;
one
juror
commented
only
that
the
25
-
millimeter
screw
looked
large
on
the
x
-
ray
admitted
into
evidence
but
was
,
in
fact
,
rather
small.
Defendant
further
maintained
that
the
foreperson
did
not
say
the
other
jurors
prevented
him
fro
m
reviewing
exhibits.
Instead
,
the
foreperson
“indicated
that
he
was
90%
for
the
defense”
when
the
final
vote
was
taken
and
that,
although
he
had
wanted
to
review
additional
-
3
-
exhibits,
he
realized
his
vote
was
unnecessary
because
the
other
jurors
were
already
in
agreement
.
Finally,
defendant
asserted
that
the
alternate
jurors
were
dismissed
after
being
selected
as
alternates
and
did
not
participate
in
deliberations.
Defendant
also
observed
that
plaintiff’s
motion
relied
on
two
nonexistent
criminal
cases
and
otherwise
cited
criminal
authority
and
constitutional
protections
inapplicable
to
this
civil
action.
Defendant
requested
sanctions.
In
reply,
plaintiff
acknowledged
that
“an
innocent
and
inadvertent
mistake
was
made”
regarding
the
citations
to
nonexistent
cases.
Plaintiff
nevertheless
continued
to
rely
primarily
on
criminal
authority.
At
the
hearing
on
plaintiff’s
motion,
the
trial
court
rejected
plaintiff’s
characterization
of
the
post
-
verdict
discussion,
finding
that
its
own
recollection
of
the
off
-
the
-
record
conversation
was
consistent
with
defendant’s
account
rather
than
plaintiff’s.
The
court
therefore
denied
plaintiff’s
motion
for
a
new
trial
or
evidentiary
hearing.
This
appeal
followed.
II.
MOTION
FOR
NEW
TRIAL
OR
EVIDENTIARY
HEARING
Turning
first
to
the
merits,
the
trial
court
did
not
abuse
its
discretion
in
denying
plaintiff’s
motion
for
a
new
trial
or
evidentiary
hearing.
Plaintiff’s
motion
relied
on
factual
allegations
outside
the
record
that
were
not
supported
by
valid
affidavits,
and
even
if
the
affidavits
were
valid,
plaintiff
did
not
show
that
any
alleged
misconduct
or
irregularity
materially
affected
her
substantial
rights.
In
civil
cases
,
motions
for
a
new
trial
are
governed
by
MCR
2.611,
and
we
review
a
trial
court’s
decision
on
a
motion
for
a
new
trial
for
an
abuse
of
discretion.
Gilbert
v
DaimlerChrysler
Corp
,
470
Mich
749,
761;
685
NW2d
391
(2004).
A
trial
court
abuses
its
discretion
when
its
decision
falls
outside
the
range
of
reasonable
and
principled
outcomes
or
when
it
commits
an
error
of
law.
Pirgu
v
United
Servs
Auto
Ass’n
,
499
Mich
269,
274
;
884
NW2d
257
(2016).
Under
MCR
2.611,
a
trial
court
may
grant
a
new
trial
when
a
party
’s
substantial
rights
were
materially
affected
by
an
“[i]rregularity
in
the
proceedings
of
the
court,
jury,
or
prevailing
party
.
.
.
which
denied
the
moving
party
a
fair
trial,”
MCR
2.611(A)(1)(a),
or
“[m]isconduct
of
the
jury
or
of
the
prevailing
party,”
MCR
2.611(A)(1)(b).
When
“the
facts
stated
in
the
motion
for
a
new
trial
.
.
.
do
not
appear
on
the
record
of
the
action,
the
motion
must
be
supported
by
affidavit,
which
must
be
filed
and
served
with
the
motion.”
MCR
2.611(D)(1).
That
affidavit
requirement
matters
here
because
plaintiff’s
motion
depended
almost
entirely
on
alleged
statements
made
during
an
off
-
the
-
record
post
-
verdict
discussion.
Those
facts
did
not
appear
in
the
recor
d,
so
plaintiff
was
required
to
support
the
motion
with
affidavits.
But
the
affidavits
plaintiff
submitted
were
not
notarized
and
were
therefore
invalid
.
See
Sherry
v
East
Suburban
Football
League
,
292
Mich
App
23,
31;
807
NW2d
859
(2011)
(“Because
an
affidavit
lacking
notarization
is
invalid,
a
tri
al
court
need
not
consider
it.”).
Plaintiff
argued
in
the
trial
court
that
the
unnotarized
affidavits
had
“the
same
effect
as
a
sworn
declaration,”
citing
§
2184
of
the
Uniform
Unsworn
Foreign
Declarations
Act,
-
4
-
MCL
600.
2181
et
seq
.
But
that
act
does
not
apply
to
declarations
made
within
the
United
States.
See
MCL
600.2183
(“This
chapter
does
not
apply
to
a
declaration
by
a
declarant
who
is
physically
located
on
property
that
is
within
the
boundaries
of
the
United
States
.
.
.
.”).
Plaintiff
therefore
offered
no
basis
to
conclude
that
the
unnotarized
statements
of
her
trial
attorneys
satisfied
MCR
2.611(D)(1).
On
appeal,
plaintiff
contends
that
the
affidavits
were
offered
only
“to
trigger
the
[evidentiary]
hearing
—
not
to
prove
medical
facts
—
and
satisfy
MCR
2.119(B)(1)
.”
That
distinction
does
not
assist
plaintiff.
When
the
asserted
facts
do
not
appear
in
the
record,
the
rule
provides
that
the
motion
“
must
be
supported
by
affidavit.”
MCR
2.611(D)(1)
(emphasis
added).
The
rule
does
not
contain
a
lesser
affidavit
requirement
for
motions
seeking
an
evidentiary
hearing
as
a
step
toward
a
new
trial.
Plaintiff
cites
no
authority
holding
that
an
unnotarized
affidavit
satisfies
that
requirement
and
has
therefore
abandoned
the
argument.
See
Mettler
Walloon,
LLC
v
Melrose
T
w
p
,
281
Mich
App
184,
220;
761
NW2d
293
(2008)
(
deeming
an
argument
abandoned
when
the
litigant
failed
to
cite
supporting
authority).
But
it
is
likely
that
plaintiff
cites
no
such
authority
because
the
plain
text
of
the
rule
,
combined
with
Sherry
’s
holding
that
an
unnotarized
affidavit
is
invalid,
strongly
suggests
that
no
such
authority
could
exist
.
Even
if
plaintiff
had
properly
supported
the
factual
allegations
in
her
motion,
she
failed
to
allege
facts
that
would
entitl
e
her
to
relief.
A
new
trial
may
be
granted
under
MCR
2.611
only
when
the
moving
party’s
substantial
rights
were
materially
affected
.
“An
error
affects
substantial
rights
if
it
caused
prejudice,
i.e.,
it
affected
the
outcome
of
the
proceedings.”
Lawrence
v
Mich
Unemployment
Ins
Agency
,
320
Mich
App
422,
443;
906
NW2d
482
(2017)
(cleaned
up).
Plaintiff
does
not
explain
how
the
alleged
misconduct
or
irregularities
affected
the
outcome
of
the
trial.
Instead,
plaintiff
relies
on
the
premise
that
juror
misconduct
“creat[es]
a
presumption
of
prejudice.”
In
support,
plaintiff
invokes
Remmer
v
United
States
,
347
US
227,
229;
74
S
Ct
450;
98
L
Ed
654
(1954).
But
Remmer
expressly
concerned
criminal
proceedings,
holding
that
“[
i
]
n
a
criminal
case
,
any
private
communication,
contact,
or
tampering
directly
or
indirectly,
with
a
juror
during
a
trial
.
.
.
is,
for
obvious
reasons,
deemed
presumptively
prejudicial
.
”
Id.
(emphasis
added).
This
is
not
a
criminal
case.
Plaintiff’s
reliance
on
the
Sixth
Amendment
and
Const
1963,
art
1,
§
20,
is
similarly
misplaced
because
those
provisions
apply
to
criminal
prosec
u
tions,
not
civil
medical
malpractice
actions.
Plaintiff
has
identified
no
non
-
criminal
authority
establishing
a
presumption
of
prejudice
under
these
circumstances.
Nor
has
plaintiff
shown
that
the
trial
court’s
refusal
to
conduct
an
evidentiary
hearing
was
an
abuse
of
discretion.
Plaintiff’s
allegations
were
unsupported
by
valid
affidavit
s,
contradicted
by
defendant’s
notarized
affidavits,
and
rejected
by
the
trial
court
based
on
its
own
recollection
of
the
post
-
verdict
discussion
in
which
it
participated.
On
this
record,
plaintiff
failed
to
demonst
rate
that
the
alleged
misconduct
or
irregularities
materially
affected
her
substantial
rights.
The
trial
court
thus
did
not
abuse
its
discretion
by
denying
plaintiff’s
motion
for
a
new
trial
or
evidentiary
hearing.

SANCTIONS
A.
COUNSEL’S
CONDUCT
We
must
also
address
significant
concerns
about
plaintiff’s
counsel’s
repeated
submission
of
fabricated
and
unsupported
legal
authority
in
the
trial
court
and
in
this
Court.
Counsel
first
cited
fabricated
authority
in
plaintiff’s
December
2024
motion
for
a
protective
order,
relying
on
“
People
v.
O’Keefe
,
2019
WL
6907273,”
regarding
the
exclusion
of
cumulative
expert
testimony.
Defendant
identified
the
fabricated
citation
in
response.
Counsel
then
sought
leave
to
file
a
reply
brief,
but
the
proposed
reply
did
not
acknowledge
or
correct
the
citation.
The
problem
recurred
two
months
later.
In
plaintiff’s
February
2025
motion
seeking
a
new
trial
or
evidentiary
hearing
based
on
juror
misconduct,
counsel
cited
two
nonexistent
criminal
cases,
“
People
v.
Stubblefield
,
197
Mich.
App.
365
(1992),”
and
“
People
v
.
Royster
,
291
Mich.
App.
508
(2011)
.”
Defendant
again
identified
the
fabricated
citations,
observed
that
this
was
not
the
first
time
plaintiff
had
cited
nonexistent
authority,
and
sought
sanctions
under
MCR
1.109
and
MCL
600.2591.
In
reply,
counsel
a
cknowledged
that
“an
innocent
and
inadvertent
mistake
was
made
regarding
the
citation
of
Stubblefield
and
Royster
.”
Yet
counsel
continued
to
rely
primarily
on
criminal
authority
and
related
constitutional
principles
in
support
of
a
motion
arising
from
a
civil
medical
malpractice
trial.
T
he
same
pattern
continued
on
appeal.
In
plaintiff’s
brief
in
this
Court
,
counsel
cited
“
Meyer
v
.
Walker
,
241
Mich
.
App
.
295
(2000),”
a
case
that
does
not
exist,
for
propositions
concerning
presumed
prejudice
and
the
standard
of
review.
Counsel
also
repeatedly
cited
real
authorities
for
propositions
they
do
not
support
.
For
example,
counsel
cited
People
v
Budzyn
,
456
Mich
77;
566
NW2d
229
(1997)
,
for
the
proposition
that
a
“trial
court’s
handling
of
juror
misconduct
allegations
is
reviewed
for
an
abuse
of
discretion,”
but
Budzyn
states
no
such
standard.
Counsel
similarly
cited
People
v
Miller
,
482
Mich
540;
759
NW2d
850
(2008)
,
for
the
proposition
that
a
“trial
court’s
management
of
trial
procedures,
including
exhibit
availability
and
deliberation
duration”
is
reviewed
for
an
abuse
of
discretion,
but
Miller
addressed
neither
issue.
In
short
,
most
of
the
citations
in
plaintiff’s
initial
brief
on
a
ppeal
do
not
support
the
propositions
for
which
they
are
offered.
Defendant
again
identified
the
deficiencies
in
his
responsive
brief,
including
the
nonexistent
citation
to
Meyer
.
Yet
plaintiff’s
counsel
then
filed
a
reply
brief
addressing
the
merits
without
acknowledging
the
fabricated
case
or
correcting
the
unsupported
legal
assertions
in
the
initial
brief.
E
ight
months
later
—
and
less
than
three
weeks
before
scheduled
oral
argument
—
plaintiff’s
counsel
filed
a
“Notice
of
Correction
.
”
In
it
,
counsel
conceded
that
Meyer
is
not
a
real
case
and
acknowledged
that
other
authorities
cited
in
plaintiff’s
brief
did
not
support
the
propositions
for
which
they
were
offered.
Counsel
accepted
“full
responsibility”
for
the
citation
errors
and
attributed
them
to
“over
-
reliance
on
artificial
intelligence
research
tools”
that
generated
“plausible
but
fabricated
case
citations
—
a
known
limitation
of
such
tools
.”
Counsel
also
represented
that
he
had
“since
impleme
nted
verification
protocols
to
prevent
recurrence.”
-
6
-
But
the
Notice
of
Correction
did
not
cure
the
problem.
Counsel
purported
to
substitute
valid
authorities
for
the
fabricated
and
unsupported
ones
,
but
those
substitute
authorities
still
did
not
support
the
propositions
for
which
counsel
offered
them.
Most
notably,
counsel
attributed
to
Miller
,
482
Mich
at
548
-
552,
quotations
concerning
“extraneous
prejudicial
information”
and
“outside
influence
.”
Those
phrases
do
not
appear
in
Miller
.
They
appear
instead
in
MRE
606(b)(2),
which
Miller
does
not
discuss.
At
oral
argument,
counsel
acknowledged
that
he
used
artificial
intelligence
to
prepare
the
Notice
of
Correction.
This
issue
is
therefore
anything
but
an
isolated
mistake
.
By
the
time
counsel
filed
plaintiff’s
brief
on
appeal,
he
had
already
been
told
twice
that
his
trial
court
filings
contained
fabricated
authority.
Yet
the
appellant’s
brief
he
filed
contained
another
fabricated
citation
and
multiple
unsupported
citations
—
a
nd
when
defendant
identified
those
problems
in
his
responsive
brief,
plaintiff’s
counsel
did
not
so
much
as
acknowledge
the
problem
in
the
reply
brief
he
subsequently
filed
,
which
otherwise
respon
ded
to
defendant’s
arguments
.
Months
later
,
counsel
represented
that
he
had
adopted
verification
protocols
—
in
a
filing
that
repeated
the
same
kind
of
verification
failure
.
This
sequence
demonstrates
counsel’s
repeated
careless
ness
regarding
his
independent
duty
to
verify
the
legal
authorities
submitted
to
the
courts.
Under
MCR
1.109(E)(5),
an
attorney’s
signature
on
a
filing
certifies
that
“he
or
she
has
read
the
document”
and
that,
“to
the
best
of
his
or
her
knowledge,
information,
and
belief
formed
after
reasonable
inquiry,
the
document
is
well
grounded
in
fact
and
is
warranted
by
existing
law.”
“The
reasonableness
of
the
inquiry
is
determined
by
an
objective
standard,”
meaning
“[t]he
attorney’s
subjective
good
faith
is
irre
levant.”
Attorney
General
v
Harkins
,
257
Mich
App
564,
576;
669
NW2d
296
(2003).
“The
requirement
of
‘reasonable
inquiry’
is
obviously
intended
to
impose
a
burden
on
pleaders
not
to
make
inaccurate
assertions
innocently
but
carelessly
.
.
.
.
Although
made
in
good
faith,
a
mistaken
legal
argument
may
not
satisfy
the
‘formed
after
reasonable
inquiry’
requirement,
which
by
its
terms
qualifies
all
of
the
subrule.”

generated
through

federal

Because

We
join
these
other
jurisdictions
and
hold
that
counsel’s
submission
of
fabricated
and
unsupported
authority
violated
the
duty
of
reasonable
inquiry
required
by
MCR
1.109(E)(5).
Counsel
cited
fabricated
authority
in
a
motion
for
a
protective
order,
cited
fabricated
authority
again
in
a
motion
for
a
new
trial
or
evidentiary
hearing,
and
then
cited
fabricated
authority
a
third
time
in
plaintiff’s
brief
on
appeal.
2
He
also
cited
real
cases
for
propositions
they
do
not
support,
invoked
criminal
constitutional
protections
in
a
civil
medical
malpractice
action,
failed
to
timely
correct
a
fabricated
appellate
citation
after
defendant
identified
it,
and
eventually
filed
a
Notice
of
Corre
ction
that
itself
attributed
quotations
and
propositions
to
cases
that
did
not
contain
them.
Counsel’s
explanation
does
not
excuse
the
violation
.
A
rtificial
intelligence
may
be
a
useful
tool
for
legal
research
and
drafting
,
b
ut
the
use
of
such
technology
does
not
alter
an
attorney’s
professional
obligations.
Lawyers
remain
responsible
for
the
filings
they
sign
and
submit.
They
must
verify
that
cited
authorities
exist,
read
the
authorities
on
which
they
rely,
and
ensure
that
those
authorities
support
the
propositions
asse
rted.
Counsel’s
repeated
reliance
on
artificial
intelligence
without
meani
ngful
verification,
despite
having
been
alerted
more
than
once
that
his
filings
contained
fabricated
authority
,
fell
below
that
standard
.
B.
APPROPRIATE
SANCTION
Counsel’s
conduct
burdened
both
defendant
and
this
Court.
Defendant
was
required
to
expend
resources
identifying
and
responding
to
fabricated
citations,
unsupported
authorities,
and
arguments
grounded
in
inapplicable
criminal
doctrine.
This
Court,
in
tur
n,
was
required
to
expend
judicial
resources
disentangling
plaintiff’s
arguments
from
authorities
that
either
did
not
exist
or
did
not
say
what
counsel
represented
them
to
say.
We
therefore
consider
the
appropriate
sanction.

The
Supreme
Court
has
since
adopted
a
new
version
of
MCR
2.114,
which
addresses
the
unrelated
topic
of
certain
proceedings
under
the
Uniform
Public
Expression
Protection
Act,
MCL
691.1851
et
seq
.
2
We
discuss
the
trial
court
filings
not
as
an
independent
basis
for
appellate
sanctions,
but
because
they
show
that
counsel
was
on
notice
before
filing
the
appellate
brief
that
his
filings
contained
fabricated
authority.
-
8
-
Under
MCR
7.216(C)(1)(b),
this
Court
may
“assess
actual
and
punitive
damages
or
take
other
disciplinary
action
when
it
determines
that
an
appeal
or
any
of
the
proceedings
in
an
appeal
was
vexatious
because”
a
brief
filed
on
appeal
“was
grossly
lacking
in
the
require
ments
of
propriety,
violated
court
rules,
or
grossly
disregarded
the
requirements
of
a
fair
presentation
of
the
issues
to
the
court.”
Counsel’s
brief
violated
MCR
1.109(E)(5)
and
grossly
disregarded
the
requirements
of
fair
presentation
by
rely
ing
on
fabricated
authority,
unsupported
citations,
and
inapplicable
criminal
doctrine.
Sanctions
are
therefore
authorized
under
MCR
7.216(C)(1)(b).
Sanctions
are
also
required
under
MCR
1.109(E)(6).
When
a
document
is
signed
in
violation
of
MCR
1.109(E)(5),
the
court
“shall
impose
.
.
.
an
appropriate
sanction,
which
may
include
an
order
to
pay
to
the
other
party
or
parties
the
amount
of
the
reasona
ble
expenses
incurred
because
of
the
filing
of
the
document,
including
reasonable
attorney
fees.”
MCR
1.109(E)(6).
Because
“the
sanctions
provided
for
by
MCR
[1.109(E)(6)]
are
mandatory”
once
a
violation
is
found,
Guerrero
v
Smith
,
280
Mich
App
647,
678;
761
NW2d
723
(2008),
we
must
determine
the
appropriate
sanction.
No
published
Michigan
decision
addresses
the
appropriate
sanction
under
MCR
7.216(C)(1)
or
MCR
1.109(E)(6)
for
an
attorney’s
submission
of
fabricated
or
unsupported
legal
authority
resulting
from
the
misuse
of
generative
artificial
intelligence
.
C
ourts
in
other
jurisdictions
,
however,
have
recognized
that
such
conduct
may
warrant
monetary
sanctions,
including
reasonable
attorney
fees
incurred
to
identify
and
respond
to
the
fabricated
authority
.
