Kim v. Kimm

16‐2944 (L) Kim v. Kimm    1  UNITED STATES COURT OF APPEALS 2  FOR THE SECOND CIRCUIT 3  August Term, 2017 4  (Submitted: October 23, 2017 Decided: February 27, 2018) 5  Docket Nos. 16‐2944, 16‐3115 6  7  8  DANIEL KIM, 9  Plaintiff‐Appellant‐Cross‐Appellee, 10  v. 11  MICHAEL S. KIMM D/B/A KIMM LAW FIRM, MICHAEL‐HYUN W. LEE, HYUNG SUK 12  CHOI A/K/A STEPHEN CHOI, CHUL HO PARK A/K/A/ CHARLIE PARK, JIN YOUNG 13  CHUNG A/K/A JAMIE CHUNG, CHARLIE AND YOU, INC. D/B/A SIK GAEK, SWAN 14  U.S.A., INC. D/B/A SIK GAEK, 15  Defendants‐Appellees‐Cross‐Appellants,  16    17  MICHAEL‐HYUN W. LEE,   18  Defendant‐Appellee,  19  20  HYUNG SUK CHOI, AKA STEPHEN CHOI, 21  Defendant. 22  23  Before: JACOBS, SACK, AND PARKER, Circuit Judges. 24  Plaintiff‐Appellant Daniel Kim appeals from a judgment entered in favor 25  of Defendants‐Appellees Michael S. Kimm, Michael‐Hyun W. Lee, Hyung Suk 26  Choi, Chul Ho Park, Charlie Park, Jin Young Chung, Charlie and You, Inc., and 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  Swan U.S.A., Inc., by the United States District Court for the Eastern District of 2  New York (Allyne R. Ross, Judge). Kim alleges that the defendants were 3  members of two enterprises that conspired to sue him for, inter alia, trademark 4  infringement, and brings claims against them pursuant to the Racketeer 5  Influenced and Corrupt Organizations Act, 18 U.S.C. § 1961, et seq. In two 6  opinions, the district court granted the defendantsʹ motion to dismiss, denied the 7  plaintiffʹs motions to disqualify the defendantsʹ counsel and for leave to amend 8  his amended complaint, and denied the defendantsʹ motion for sanctions. We 9  agree with the district courtʹs resolution of these motions. Accordingly, the 10  judgment of the district court is 11  AFFIRMED. 12  DANIEL KIM, Haworth, NJ, Plaintiff‐ 13  Appellant‐Cross‐Appellee, pro se. 14  MICHAEL S. KIMM, ADAM GARCIA, Kimm 15  Law Firm, Englewood Cliffs, NJ, for  16  Defendants‐Appellees‐Cross‐Appellants.  17  SACK, Circuit Judge: 18  The plaintiff Daniel Kim brings this action pursuant to the Racketeer 19  Influenced and Corrupt Organizations Act (ʺRICOʺ), 18 U.S.C. § 1961, et seq., 20  alleging that the defendants engaged in a scheme to fraudulently bring suit 2 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  against him for, inter alia, trademark infringement. The defendants moved to 2  dismiss the action for failure to state a claim under Federal Rule of Civil 3  Procedure 12(b)(6), arguing that their prior acts, as part of litigation they brought 4  against the plaintiff, do not constitute predicate acts for purposes of RICO. Kim 5  subsequently moved to disqualify defendant Michael S. Kimm as counsel for the 6  defendants and sought leave to further amend his amended complaint. 7  The United States District Court for the Eastern District of New York 8  (Allyne R. Ross, Judge) dismissed Kimʹs action for failure to state a claim, 9  agreeing with the defendants that Kim could not sustain a RICO action based on 10  the defendantsʹ prior litigation activities. The district court also denied Kimʹs 11  motion for leave to amend and to disqualify Kimm as counsel for the defendants. 12  The defendants then moved for sanctions pursuant to Federal Rules of Civil 13  Procedure Rule 11. The district court denied the motion. 14  Kim, now proceeding pro se, appeals the district courtʹs judgment 15  dismissing his action and the district courtʹs denial of his motions for leave to 16  amend and to disqualify Kimm. Kimm and his co‐defendants cross‐appeal, 17  challenging the district courtʹs denial of sanctions against Kim. We agree with 18  the district court that the alleged litigation activities do not constitute RICO 3 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  predicate acts. We also conclude that the district court did not abuse its 2  discretion in denying Kim leave to amend, Kimʹs motion to disqualify, and the 3  defendantsʹ motion for sanctions. The judgment of the district court is therefore 4  affirmed.  5  BACKGROUND  6  I. The Sik Gaek I Lawsuit  7  The instant action arises from an earlier litigation, Sik Gaek, Inc. v. Yogiʹs II,  8  Inc., et al., No. 10‐CV‐4077 (ARR) (E.D.N.Y. 2010) (ʺSik Gaek Iʺ), which was filed in 9  the United States District Court for the Eastern District of New York on 10  September 7, 2010. In Sik Gaek I, Sik Gaek, Inc., the owner and operator of a 11  restaurant, sued Daniel Kim and the restaurant Kim owned, Yogiʹs II, Inc., over 12  the use of a trademark that Sik Gaek, Inc. allegedly owned. Sik Gaek, Inc. 13  alleged that Kim and Yogiʹs II, Inc. had failed to pay a $2 million fee pursuant to 14  a trademark license agreement and that, ʺin a sinister scheme,ʺ Kim had 15  attempted to circumvent the license and register the trademark himself.   16  Appellant Appʹx at 48–52. Sik Gaek, Inc. brought claims against Kim and Yogiʹs 17  II, Inc. for, inter alia, breach of contract, fraudulent trademark registration, and 18  trademark infringement. The district court granted summary judgment in favor 4 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  of the defendant Kim on August 14, 2014. Sik Gaek, Inc. v. Yogiʹs II, Inc., 2014 WL 2  4063403, 2014 U.S. Dist. LEXIS 113165 (E.D.N.Y. Aug. 14, 2014). On August 21, 3  2014, the remaining claims against the defendant Yogiʹs II, Inc. were dismissed 4  by agreement of the parties. 5  II. District Court Proceedings  6  On August 15, 2015, Daniel Kim, a lawyer and a defendant in Sik Gaek I, 7  filed the instant action, bringing claims against parties in the Sik Gaek I lawsuit: 8  the owner of Sik Gaek, Inc., his wife and business partner, their two attorneys, 9  and an accountant. In his amended complaint, Kim alleges that the defendants 10  were members of two criminal enterprises that conspired to sue him for 11  trademark infringement and breach of contract in Sik Gaek I. According to Kim, 12  the Sik Gaek I lawsuit was nothing more than an ʺill‐conceived scheme or artificeʺ 13  designed to ʺextort $2 millionʺ from him. Appellant Appʹx at 9. Kim alleges that 14  the defendants completed false paperwork to pose as the owners of a trademark, 15  licensed the trademark to a third‐party, and then sued Kim for violating the 16  licensing agreement. Kim claims that these false legal documents were intended 17  to mislead the district court and therefore were predicate acts of obstruction of 18  justice, mail fraud, and wire fraud that constituted a pattern of racketeering 5 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  activity. Kim also brought a RICO conspiracy claim, alleging that ʺthe entire 2  scheme or artifice could never have been set in motion without the express 3  agreement, cooperation and coordination of each individual defendant and his 4  assigned role.ʺ Appellant Appʹx at 40.  5  On September 11, 2015, the defendants filed a motion to dismiss for failure 6  to state a claim pursuant to Rule 12(b)(6) of the Federal Rules of Civil Procedure. 7  The defendants argued that Kim had failed adequately to allege a pattern of 8  racketeering activity, as required to state a RICO claim. The defendants raised 9  other arguments supporting their motion to dismiss, based on, inter alia, the 10  doctrines of collateral estoppel and res judicata. Kim subsequently moved to 11  disqualify Kimm as counsel in this litigation and to bar him from participating in 12  any defendantʹs defense other than his own. Kim also opposed the defendantsʹ 13  motion to dismiss and moved for leave to file a second amended complaint.   14  By unpublished opinion and order dated August 9, 2016, the district court 15  granted the defendantsʹ motion to dismiss. Appellant Appʹx at 257–76. The 16  court decided that Kim had failed to state a RICO claim because he had not 17  alleged predicate acts constituting a pattern of racketeering activity. The court 18  found that most of the alleged predicate acts concerned litigation activity in Sik  6 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  Gaek I—specifically, the preparing, signing, and filing of declarations by Chul Ho 2  Park, Michael Kimm, and Hyung Suk Choi, all of whom are defendants in the 3  instant action—and reasoned that ʺ[w]ell‐established precedent and sound 4  public policy preclude such litigation activities from forming the basis for 5  predicate acts under [RICO].ʺ Dist. Ct. Op. at 8, Appellant Appʹx at 264. The 6  district court noted that Kimʹs amended complaint also included pre‐litigation 7  activities alleged as predicate acts, but found these allegations deficient as a 8  matter of law. 9  In its August 9, 2016, opinion and order, the district court also denied 10  Kimʹs motion to disqualify Kimm as counsel, concluding that the motion was 11  rendered moot by the district courtʹs dismissal of Kimʹs amended complaint. 12  Finally, the district court denied Kim leave to amend his complaint, reasoning 13  that amendment would be futile because the proposed amendments only added 14  additional litigation activities by the defendants which, as such, were insufficient 15  to form the basis for a RICO predicate act.  16  The defendants then moved for sanctions against Kim, arguing that his 17  lawsuit was meritless and seeking to recover fees expended in defending the Sik  18  Gaek I litigation. The district court denied the motion and in an unpublished 7 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  opinion and order dated August 12, 2016, concluded that Kimʹs claims were 2  neither legally nor factually frivolous. The district court reasoned that although 3  it had joined the majority of courts in concluding that litigation activity could not 4  be predicate acts under RICO, at least some courts held differently and sanctions 5  were therefore inappropriate. 6  Kim timely appealed to this Court from the district courtʹs dismissal of his 7  action and denial of his motions for leave to amend his complaint and to 8  disqualify Kimm. The defendants timely cross‐appealed from the district courtʹs 9  denial of their motion for sanctions.  10  DISCUSSION  11  I. Failure to State a RICO Claim 12  The first issue in this appeal is whether the district court erred in granting 13  the defendantsʹ motion to dismiss pursuant to Rule 12(b)(6). Kim challenges the 14  district courtʹs holding that the defendantsʹ alleged litigation activities did not 15  constitute predicate acts for purposes of RICO.1                                                              Kim does not raise any arguments regarding the district courtʹs holding that the 1 alleged pre‐litigation activities failed to state a RICO claim. We therefore conclude that Kim has waived any such argument. See Norton v. Samʹs Club, 145 F.3d 114, 117 (2d Cir. 1998). 8 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  ʺWe review de novo a district courtʹs dismissal of a complaint pursuant to 2  Rule 12(b)(6), construing the complaint liberally, accepting all factual allegations 3  in the complaint as true, and drawing all reasonable inferences in the plaintiffʹs 4  favor.ʺ Chambers v. Time Warner, Inc., 282 F.3d 147, 152 (2d Cir. 2002). To survive 5  a motion to dismiss, a complaint ʺmust contain sufficient factual matter, accepted 6  as true, to state a claim to relief that is plausible on its face.ʺ Ashcroft v. Iqbal, 556 7  U.S. 662, 678 (2009) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007) 8  (internal quotation marks omitted)). 9  A. RICO  10  Section 1964(c) of RICO, 18 U.S.C. §§ 1961–1968, provides a private right of 11  action to any person injured in its business or property by reason of a violation of 12  the activities prohibited by section 1962. ʺTo establish a RICO claim, a plaintiff 13  must show: (1) a violation of . . . 18 U.S.C. § 1692; (2) an injury to business or 14  property; and (3) that the injury was caused by the violation of Section 1962.ʺ 15  Cruz v. FXDirectDealer, LLC, 720 F.3d 115, 120 (2d Cir. 2013) (quoting DeFalco v.  16  Bernas, 244 F.3d 286, 305 (2d Cir. 2001)). This appeal implicates the first of these 17  requirements, viz., whether the plaintiff has adequately alleged a violation of 18  section 1962. To establish such a violation, a plaintiff must show ʺ(1) conduct 9 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  (2) of an enterprise (3) through a pattern (4) of racketeering activity.ʺ DeFalco v.  2  Bernas, 244 F.3d 286, 306 (2d Cir. 2001) (quoting Sedima, S.P.R.L. v. Imrex Co., 473 3  U.S. 479, 496 (1985)). 4  Here, the defendants argue—and the district court held—that Kim failed 5  adequately to allege a pattern of racketeering activity. ʺRacketeering activityʺ is 6  defined to include any ʺactʺ indictable under various specified federal statutes, 7  including the mail and wire fraud statutes and the obstruction of justice statute. 8  See 18 U.S.C. § 1961(1) (defining ʺracketeering activityʺ to include offenses 9  indictable under 18 U.S.C. §§ 1341 (relating to mail fraud), 1343 (relating to wire 10  fraud), and 1503 (relating to obstruction of justice)). A ʺpattern of racketeering 11  activityʺ is defined by the statute as ʺat least two acts of racketeering activityʺ 12  within a ten‐year period. 18 U.S.C. § 1691(5). 13  B. Litigation Activity as RICO Predicate Acts  14  Here, Kim purports to allege various predicate acts of mail fraud, wire 15  fraud, and obstruction of justice allegedly committed by the defendants. Most of 16  the alleged predicate acts concern actions purportedly taken by the defendants 17  during the Sik Gaek I litigation. Specifically, Kim alleges that the defendants 18  committed obstruction of justice, mail fraud, and wire fraud by: 10 16‐2944, 16‐3115 Kim v. Kimm, et al.    1   Preparing, signing, and electronically filing a November 14, 2010, 2  declaration sworn by defendant Chul Ho Park; 3   Preparing, signing, and filing a December 21, 2010, declaration sworn to 4  by defendant Park; 5   Preparing, signing, and filing a February 13, 2012, declaration sworn by 6  defendant Kimm; and 7   Preparing, signing, and filing a March 14, 2014, declaration sworn by 8  defendant Hyung Suk Choi. 9  Kim alleges that each of the four declarations were prepared, signed, and 10  filed with full knowledge that they contained fraudulent representations 11  intended to persuade the district court to find in favor of Sik Gaek, Inc.  The 12  district court concluded that these litigation activities could not provide a basis 13  for predicate acts under Section 1962(c). It therefore dismissed Kimʹs complaint 14  for failure to state a claim. We affirm for substantially the reasons set forth by 15  the district court. 16  Although we have not spoken directly on the issue, other courts have held 17  that ʺ[i]n the absence of corruption,ʺ such litigation activity ʺcannot act as a 11 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  predicate offense for a civil‐RICO claim.ʺ Snow Ingredients, Inc. v. SnoWizard, Inc., 2  833 F.3d 512, 525 (5th Cir. 2016); Raney v. Allstate Ins. Co., 370 F.3d 1086, 1087–88 3  (11th Cir. 2004) (deciding that the ʺalleged conspiracy to extort money through 4  the filing of malicious lawsuitsʺ were not predicate acts of extortion or mail fraud 5  under RICO); Deck v. Engineered Laminates, 349 F.3d 1253, 1258 (10th Cir. 2003) 6  (deciding that meritless litigation is not a predicate act of extortion under RICO); 7  Gabovitch v. Shear, 70 F.3d 1252 (table), 1995 WL 697319, at *2, 1995 U.S. App. 8  LEXIS 32856, at *5 (1st Cir. 1995) (per curiam) (concluding that ʺproffering false 9  affidavits and testimony to [a] state courtʺ does not constitute a predicate act of 10  extortion or mail fraud); see also Curtis & Assocs., P.C. v. Law Offices of David M.  11  Bushman, Esq., 758 F. Supp. 2d 153, 171–72 (E.D.N.Y. 2010) (collecting cases from 12  district courts in the Second Circuit deciding ʺthat the litigation activities alleged 13  in [the complaint before the court] cannot properly form the basis for RICO 14  predicate actsʺ). We agree with the reasoning of these opinions and conclude 15  that allegations of frivolous, fraudulent, or baseless litigation activities—without 16  more—cannot constitute a RICO predicate act. 17  As the district court explained, there are compelling policy arguments 18  supporting this rule. First, ʺ[i]f litigation activity were adequate to state a claim 12 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  under RICO, every unsuccessful lawsuit could spawn a retaliatory action,ʺ which 2  ʺwould inundate the federal courts with procedurally complex RICO pleadings.ʺ 3  Dist. Ct. Op. at 10–11, Appellant Appʹx at 266–67; see also Nora F. Engstrom, 4  Retaliatory RICO and the Puzzle of Fraudulent Claiming, 115 MICH. L. REV. 639, 696 5  (2017) (permitting RICO suits based on prior litigation activities would 6  ʺengender wasteful satellite litigationʺ). Furthermore, ʺpermitting such claims 7  would erode the principles undergirding the doctrines of res judicata and 8  collateral estoppel, as such claims frequently call into question the validity of 9  documents presented in the underlying litigation as well as the judicial decisions 10  that relied upon them.ʺ Dist. Ct. Op. at 11, Appellant Appʹx at 267; see also 11  Gabovitch, 1995 WL 697319, at *3, 1995 U.S. App. LEXIS 32856, at *7‐8 (ʺIn essence, 12  simply by alleging that defendantsʹ litigation stance in the state court case was 13  ʹfraudulent,ʹ plaintiff is insisting upon a right to relitigate that entire case in 14  federal court . . . . The RICO statute obviously was not meant to endorse any 15  such occurrence.ʺ). Moreover, endorsing this interpretation of RICO ʺwould chill 16  litigants and lawyers and frustrate the well‐established public policy goal of 17  maintaining open access to the courtsʺ because ʺany litigantʹs or attorneyʹs 18  pleading and correspondence in an unsuccessful lawsuit could lead to drastic 13 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  RICO liability.ʺ Dist. Ct. Op. at 11, Appellant Appʹx at 267 (quoting Curtis &  2  Assocs., 758 F. Supp. 2d at 173); see also Engel v. CBS, Inc., 182 F.3d 124, 129 (2d 3  Cir. 1999) (noting the ʺstrong public policy of open access to the courts for all 4  parties and [the need] to avoid ad infinitum [litigation] with each party claiming 5  that the opponentʹs previous action was malicious and meritlessʺ (internal 6  quotation marks and citations omitted) (second brackets in original)). 7  Kim relies on Sykes v. Mel S. Harris & Associates LLC, 780 F.3d 70 (2d Cir. 8  2015) to argue that this Court ʺhas recognized RICO claims against attorneys . . . 9  for obtaining default judgments under false pretenses set forth in sham affidavits 10  of services.ʺ Appellant Br. at 16. Kimʹs reliance on this case is misplaced. As a 11  preliminary matter, it seems likely that Kim meant to cite a district court opinion 12  in that case, Sykes v. Mel Harris & Assocs., LLC, 757 F. Supp. 2d 413, 418 (S.D.N.Y. 13  2010), instead. There, the district court denied the defendantsʹ motion to dismiss 14  the plaintiffsʹ section 1962(c) claims, observing that the plaintiffs pleaded a 15  pattern of racketeering activity that included ʺat least twenty allegedly 16  fraudulent statements and eighteen acts involving use of the mail and wires over 17  three years, in furtherance of the alleged fraud.ʺ Id. at 425. Our 2015 opinion 18  cited by Kim addressed whether the district court abused its discretion by 14 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  certifying class actions; we did not review the district courtʹs denial of the 2  defendantsʹ motion to dismiss. See Sykes, 780 F.3d at 79–80. 3  The district court opinion, even were it binding on us—which, unlike this 4  Courtʹs subsequent decision, of course, it is not—is also distinguishable from the 5  case at bar. The plaintiffs in Sykes alleged that the defendants engaged in a 6  ʺmassive scheme,ʺ in which a debt‐buying company, a law firm, a process‐ 7  serving company, and others conspired with one another by buying consumer 8  debt, initiating actions against the debtors and improperly serving them, and 9  then filing fraudulent documents in state court to obtain default judgments. Id. 10  at 418–20. Accordingly, even though those defendants used litigation to carry 11  out their scheme, they also engaged in a variety of other out‐of‐court actions to 12  further this activity. In the case at bar, by contrast, the entire alleged scheme 13  involved the creation of fraudulent court documents. 14  We decline to reach the issue of whether all RICO actions based on 15  litigation activity are categorically meritless. We conclude only that where, as 16  here, a plaintiff alleges that a defendant engaged in a single frivolous, fraudulent, 17  or baseless lawsuit, such litigation activity alone cannot constitute a viable RICO 18  predicate act. We therefore agree with the district courtʹs thorough and well‐ 15 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  reasoned analysis to that effect and affirm its dismissal of Kimʹs amended 2  complaint. 3  II. Leave to Amend the Complaint  4  Kim contends that the district court also erred by denying him leave to file 5  a second amended complaint. We review the district courtʹs denial of leave to 6  amend for abuse of discretion. ATSI Commcʹns, Inc. v. Shaar Fund, Ltd., 493 F.3d 7  87, 108 (2d Cir. 2007). ʺAlthough Rule 15(a) of the Federal Rules of Civil 8  Procedure provides that leave to amend ʹshall be freely given when justice so 9  requires,ʹ it is within the sound discretion of the district court to grant or deny 10  leave to amend.ʺ McCarthy v. Dun & Bradstreet Corp., 482 F.3d 184, 200 (2d Cir. 11  2007) (citation omitted). Leave to amend may be denied ʺfor good reason, 12  including futility, bad faith, undue delay, or undue prejudice to the opposing 13  party.ʺ Id. Here, Kimʹs proposed second amended complaint only added more 14  litigation‐related predicate acts, such as allegations pertaining to deposition 15  testimony, declarations, and court filings that he contends were fraudulent. 16  These proposed amendments do not change the nature of the alleged predicate 17  acts—litigation activities—which for the reasons discussed above, are deficient as 18  a matter of law. Therefore, because the proposed amendments would have no 16 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  impact on the basis for the district courtʹs dismissal and would consequently be 2  futile, the district court did not abuse its discretion in denying Kim leave to 3  amend. See Ellis v. Chao, 336 F.3d 114, 127 (2d Cir. 2003) (ʺ[I]t is well established 4  that leave to amend a complaint need not be granted when amendment would be 5  futile.ʺ). 6  III. Motion to Disqualify 7  Kim next argues that the district court erred by denying Kimʹs motion to 8  disqualify Kimm as counsel for the defendants. We review the district courtʹs 9  failure to disqualify counsel for abuse of discretion. See Bobal v. Rensselaer  10  Polytechnic Inst., 916 F.2d 759, 764 (2d Cir. 1990). Kim contends that the district 11  court should have disqualified Kimm under the ʺadvocate‐witnessʺ rule. “The 12  advocate‐witness rule applies, first and foremost, where the attorney 13  representing the client before a jury seeks to serve as a fact witness in that very  14  proceeding.” Ramey v. Dist. 141, Int’l Ass’n of Machinists & Aerospace Workers, 378 15  F.3d 269, 282 (2d Cir. 2004) (first emphasis added; second emphasis in the 16  original). Here, the district court decided that Kimʹs motion to disqualify was 17  moot because it had already dismissed Kimʹs amended complaint with prejudice. 18  This was not an abuse of discretion. After the district court dismissed Kimʹs 17 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  amended complaint, there was no likelihood that Kimm would testify as a fact 2  witness before a jury. Therefore, the district court properly dismissed Kimʹs 3  disqualification motion as moot. 4  IV. Motion for Sanctions 5  The defendants argue that the district court erred in denying their motion 6  for sanctions against Kim, which they sought pursuant to Rule 11 of the Federal 7  Rules of Civil Procedure and 28 U.S.C. § 1927.2 Rule 11 requires the ʺattorney or 8  unrepresented partyʺ filing litigation documents to certify that the documents: 9  (1) [are] not being presented for any improper purpose, such as 10  to harass, cause unnecessary delay, or needlessly increase the 11  cost of litigation [and] (2) the claims, defenses, and other legal 12  contentions are warranted by existing law or by a nonfrivolous 13  argument for extending, modifying, or reversing existing law or 14  for establishing new law. 15  16  Fed. R. Civ. P. 11(b). 28 U.S.C. § 1927 provides that ʺ[a]ny attorney . . . who so 17  multiplies the proceedings in any case unreasonably and vexatiously may be 18  required by the court to satisfy personally the excess costs, expenses, and                                                              Although 28 U.S.C. § 1927 only reaches attorneys, the provision was potentially 2 applicable because Kim was represented by counsel before the district court, only proceeding pro se in this appeal. Insofar as Kim himself had undertaken conduct violating § 1927, he also could have been sanctioned under that provision because he is in fact a lawyer, and we have held that § 1927 reaches litigants proceeding pro se who are lawyers. See Sassower v. Field, 973 F.2d 75, 80 (2d Cir. 1992). 18 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  attorneysʹ fees reasonably incurred because of such conduct.ʺ To impose 2  sanctions under this provision, ʺa court must find clear evidence that (1) the 3  offending partyʹs claims were entirely without color, and (2) the claims were 4  brought in bad faith—that is, ʹmotivated by improper purposes such as 5  harassment or delay.ʹʺ Eisemann v. Greene, 204 F.3d 393, 396 (2d Cir. 2000) 6  (quoting Schlaifer Nance & Co. v. Estate of Warhol, 194 F.3d 323, 336 (2d Cir. 1999)). 7  We review the district courtʹs denial of sanctions for abuse of discretion. Perez v.  8  Posse Comitatus, 373 F.3d 321, 325–26 (2d Cir. 2004). 9  The defendants argue that sanctions were appropriate because Kimʹs 10  claims were legally and factually frivolous. We conclude, however, that 11  although Kimʹs amended complaint ultimately failed to state a RICO claim, his 12  claims were not so obviously foreclosed by precedent as to make them legally 13  indefensible. At the time Kim filed this suit, there was no binding precedent in 14  this Circuit as to whether litigation activities could serve as predicate acts for 15  purposes of RICO. Indeed, some courts had endorsed the viability of some such 16  claims. See Sykes, 757 F. Supp. 2d at 425–26. Therefore, Kimʹs claims ʺwere not 17  foreclosed a priori by binding precedent even if they were unlikely to succeedʺ 18  and Kimʹs position ʺwas not unsupported by case law even though the cases he 19 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  cited were not binding on the court adjudicating his claims.ʺ Fishoff v. Coty Inc., 2  634 F.3d 647, 655 (2d Cir. 2011). 3  The defendants assert that sanctions are also appropriate because Kimʹs 4  claims are barred by the doctrines of collateral estoppel and res judicata, 5  rendering Kimʹs lawsuit frivolous. However, the defendants raise this issue only 6  in a cursory manner, without advancing any substantive arguments to support 7  their claim that Kimʹs lawsuit is precluded by earlier litigation. We therefore 8  conclude that the defendants have waived this argument. See Lederman v. New  9  York City Depʹt of Parks & Recreation, 731 F.3d 199, 203 n.1 (2d Cir. 2013) 10  (ʺ[A]ppellants must include in their briefs their ʹcontentions and the reasons for 11  them, with citations to the authorities and parts of the record on which the 12  appellant relies.ʹ Issues not sufficiently argued will be deemed waived and 13  ineligible for appellate review.ʺ (quoting Fed. R. App. P. 28(a)(9)(A))). 14  For these reasons, we conclude that the district court did not abuse its 15  discretion in denying the defendantsʹ motion for sanctions. 20 16‐2944, 16‐3115 Kim v. Kimm, et al.    1  CONCLUSION  2  We have considered the partiesʹ remaining arguments on appeal and find 3  them to be without merit. For the foregoing reasons, we AFFIRM the judgment 4  of the district court. 21
