Opinion

USDC SDNY UNITED STATES DISTRICT COURT DOCUMENT SOUTHERN DISTRICT OF NEW YORK ELECTRONICALLY FILED WAI LUN CHUI, DOC DATE FILED: 7/23/2026 Plaintiff, -against- 24 Civ. 6767 (AT) PUBLICIS GROUPE S.A., LION RESOURCES OPINION AND ORDER INC, MMS USA HOLDINGS, INC. and EPSILON DATA MANAGEMENT, Defendants. ANALISA TORRES, District Judge: Before the Court is Plaintiff, Wai Lun Chui’s, motion for leave to file an amended complaint. See Mot., ECF No. 54; Mem., ECF No. 54-1; Prop. Am. Compl. (“PAC”), ECF No. 54-3;! Opp., ECF No. 56. For the reasons stated below, the motion is DENIED, and the case is DISMISSED. BACKGROUND? Plaintiff is a former employee of Defendant, Publicis Groupe S.A. (“Publicis”), who worked for Publicis “and its subsidiaries” from 2016 through May 20, 2021. See Mot. to Dismiss Ord. at 2, ECF No. 51; see also Compl. JJ 3, 4, 6, ECF No. 1. On September 6, 2024, Plaintiff filed this action against Defendants, alleging age discrimination in violation of the Age Discrimination in Employment Act of 1967 (“ADEA”), 29 U.S.C. § 621 et seq., discrimination on the basis of race, national origin, and religion, in violation of Title VII of the Civil Rights Act of 1964 (“Title □□□□□□ 42 U.S.C. § 2000e et seg., and retaliation in violation of Title VII, the Sarbanes-Oxley Act (“SOX”), 18 U.S.C. § 1514A, and the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd- Frank”), 15 U.S.C. § 78u-6(h). See Compl. at 4—S.

' Plaintiff has filed his proposed amended complaint, an affidavit from his attorney, a copy of a prior order of this court, and a redline copy of the proposed complaint as one document on ECF. See ECF No. 54-3. The Court shall refer to the entire document as “PAC” and use the pagination of the PDF document at ECF No. 54-3 for citations. ? The Court presumes familiarity with the facts of this case and recounts them only as necessary for this decision. See ECF No. 51 at 2-3 (providing factual background in deciding Defendants’ motion to dismiss).

On September 23, 2025, the Court dismissed Plaintiff’s complaint for failure to exhaust his administrative remedies and for failure to state a claim. See Fed. R. Civ. P. 12(b)(1), (b)(6). First, as to Plaintiff’s claim under SOX, the Court noted that a plaintiff “must [] file a claim with the Occupational Safety and Health Administration (‘OSHA’) within 180 days of the alleged retaliatory action” for a Court to have jurisdiction to hear a SOX claim. See Mot to Dismiss Ord. at 4 (citing 18 U.S.C. § 1514A(h). The Court held that because Plaintiff did not allege “that he filed [any] claim before OSHA—let alone, a claim within 180 days of any alleged retaliatory action,” the claim was time-barred and the Court lacked jurisdiction to review it. See id.; see also Daly v. Citigroup Inc., 939 F.3d 415, 426, 428 (2d Cir. 2019) (explaining that administrative exhaustion under SOX is a

jurisdictional requirement). On Plaintiff’s Dodd-Frank claim, the Court held that Plaintiff had failed to plead that he had provided “information relating to a violation of the securities laws to the [Securities and Exchange] Commission” (“SEC”), a requirement for a Dodd-Frank whistleblower claim. Mot. to Dismiss Ord. at 11 (quoting Digital Realty Tr., Inc. v. Somers, 583 U.S. 149, 153 (2018)). Concerning Plaintiff’s ADEA and Title VII claims, the Court noted that Plaintiff, by his own admission, had not timely filed a charge of discrimination with the Equal Employment Opportunity Commission (“EEOC”) and had not timely filed a complaint in this District after receiving his right-to-sue letter, and held that this action was not one of those “rare and exceptional circumstances, in which a party is prevented in some extraordinary way from exercising his rights” such that equitable tolling of these deadlines was warranted. Id. at 6 (quoting Zerilli-Edelglass v.

N.Y.C. Transit Auth., 333 F.3d 74, 80 (2d Cir. 2003) (cleaned up)). The Court then dismissed Plaintiff’s ADEA and Title VII claims as untimely. The Court also dismissed Plaintiff’s ADEA and Title VII claims on the merits. See id. at 7. On the age discrimination claim, the Court found that Plaintiff had not alleged any facts supporting an inference of age discrimination; at best, he conclusorily asserted that he was fired to achieve “cost savings” without providing the factual basis for this assertion or an inference that the need for cost savings was tied to his age. Id. at 8 (quoting Compl. ¶ 13). On the race, national origin, and religious discrimination claims under Title VII, the Court similarly concluded that the complaint lacked sufficient factual information to assert a claim. See id. at 9. Plaintiff now moves for leave to amend the complaint, arguing that he filed an EEOC charge on July 16, 2021—within 180 days of his termination on May 21 of that year. Mem. at 5–6. Plaintiff’s PAC includes: (1) additional factual allegations concerning Publicis’ acquisition of Epsilon and Plaintiff’s internal complaints regarding the acquisition, see PAC at 19–21; (2) a new retaliatory interference claim under the Employee Retirement Income and Securities Act (“ERISA”), see id. at

23; (3) new claims alleging discrimination on the basis of “age, religion, color, and origin” under the New York State Human Rights Law (“NYSHRL”) and New York City Human Rights Law (“NYCHRL”), see id. at 23–24; and (4) a new common-law claim for “[c]onstructive [f]raud / [n]egligent [m]isrepresentation,” see id. at 24. The PAC does not contain any additional factual allegations concerning Plaintiff’s age, religion, race, or national origin claims. See PAC at 19–22. LEGAL STANDARD Under Rule 15, leave to amend should be “freely give[n] ... when justice so requires.” Fed. R. Civ. P. 15(a)(2). However, a Court may deny leave to amend “upon a showing of ‘undue delay, bad faith, dilatory motive, [or] futility.’” Sacerdote v. New York Univ., 9 F.4th 95, 115 (2d Cir. 2021) (quoting Loreley Fin. (Jersey) No. 3 Ltd. v. Wells Fargo Sec., LLC, 797 F.3d 160, 190 (2d Cir.
