RADU COJOCARU, Case No.: 24cv1770-W-KSC

Plaintiff, ORDER GRANTING MOTION FOR v. LEAVE TO FILE SECOND AMENDED COMPLAINT [DOC. 39] Defendant. Before the Court is Radu Cojocaru’s (“Plaintiff”) motion for leave to file a second amended complaint (“SAC”). (Mtn. Amend [Doc. 39].) Merck Sharp & Dohme LLC (“Defendant”) filed an opposition (Opp’n [Doc. 55]), and Plaintiff filed a reply (Reply [Doc. 56]). The Court decides the matter on the papers submitted and without oral argument pursuant to Civil Local Rule 7.1(d)(1). For the reasons discussed below, the Court GRANTS the motion [Doc. 39]. Plaintiff initiated this action by filing a complaint in San Diego Superior Court, which was removed to this Court based on diversity jurisdiction. (Compl. [Doc. 1].) Shortly after the removal, Plaintiff filed a first amended complaint (“FAC”). (FAC [Doc. 5].) Plaintiff was employed by Defendant as a Principal Scientist/Director of Bioinformatics beginning in December 2023 and was terminated from the position in June 2024. (FAC at 2.) Plaintiff alleges several causes of action against Defendant, including violation of California labor code, breach of contract, wrongful termination of employment in violation of public policy, and defamation. (See FAC.) Plaintiff now seeks to amend the FAC: (a) to add facts in support of his existing causes of action for violation of California Labor Code § 1198.5, for breach of contract, and for wrongful termination in violation of public policy . . . . (b) to add legal theories in support of his existing causes of action for breach of Labor Code § 1198.5, breach of contract, and wrongful termination in violation of public policy, specifically the doctrines of forfeiture/waiver of argument, unconscionability, and right to privacy; and (c) to clarify the damages sought for loss of severance or separation pay based on Defendant’s production of its applicable policy after the filing of litigation. (Mtn. Amend at 3-4.) Defendant argues that Plaintiff’s motion should be denied because it involves “undue delay,” the parties have exchanged “voluminous discovery,” and the amendment would cause “substantial prejudice to Defendant,” which Defendant claims “signals bad faith.” (Opp’n at 2.) Defendant also argues that the amendment would be futile because it is based on a legal theory that has “already been rejected by California courts.” (Id.) Federal Rule of Civil Procedure 15(a) provides that after a responsive pleading has been served, a party may amend its complaint only with leave of court, and leave “shall be freely given when justice so requires.” Fed. R. Civ. P. 15(a). Granting leave to amend rests in the sound discretion of the district court. Pisciotta v. Teledyne Industries, Inc., 91 F.3d 1326, 1331 (9th Cir. 1996). Although leave to amend is not to be granted automatically, the rule should be interpreted with extreme liberality. Jackson v. Bank of Hawaii, 902 F.2d 1385, 1387 (9th Cir. 1990) (citations omitted). Five factors are considered to assess the propriety of a motion for leave to amend: (1) bad faith, (2) undue delay, (3) prejudice to the opposing party, (4) futility of amendment, and (5) whether the plaintiff has previously amended the complaint. Johnson v. Buckley, 356 F.3d 1067, 1077 (9th Cir. 2004). A. Bad Faith and Undue Delay Plaintiff argues that the above factors favor granting leave to amend. (Mtn. Amend at 5.) Plaintiff asserts that he “lacked knowledge” of the “clarifying facts and additional legal theories or doctrines” included in the proposed SAC because “Defendant wrongfully withheld documents relating to his termination prior to ligation” and continued to do so during discovery until ordered by Magistrate Judge Crawford to produce them unredacted. (Id.) Plaintiff further states that he was “severely handicapped” in filing the original complaint and FAC due to the absence of employment records relating to his termination and Defendant’s conflict-of-interest-policy. (Mtn. Amend Dec. [Doc. 39-1] at 2.) Defendant opposes leave to amend on the ground that Plaintiff has been in possession of the information underlying the proposed amendments for many months, which “reflects strategic gamesmanship rather than a good-faith effort” to respond in a timely manner to facts allegedly discovered. (Opp’n at 2-8.) Defendant explains that its conflict-of-interest policy was produced as part of its initial disclosures on December 11, 2024. (Opp’n Dec. [Doc. 55-1] at 2.) Plaintiff does not dispute receiving the policy and termination related records on that date, but he contends that the production was “very selective” and did not include other requested documents. (Mtn. Amend Dec. at 2.) Plaintiff maintains that he did not receive the remaining documents until April 2, 2025, and that on June 30, 2025, Magistrate Judge Crawford ordered Defendant to produce the documents unredacted and designated “FOR COUNSEL ONLY.” (Id.) The record reflects, however, that the June 30, 2025, discovery order pertained to materials containing confidential trade secrets. (See Disc. Order [Doc. 37].) Plaintiff moreover acknowledges that the proposed amendment was prompted, not by the belated discovery of new facts, but by his review of Defendant’s already produced documents and Defendant’s questioning of Plaintiff during his May 1 deposition, after which Plaintiff concluded that Defendant was applying a “broad and vague” conflict-of-interest policy in an “unconscionably unfair and intrusive manner,” and he then “immediately prepared the proposed Second Amended Complaint.” (Mtn. Amend Dec. at 2.) Therefore, the motion to amend rests on a new interpretation of information that had been in Plaintiff’s possession for months. While that assessment may assist with new legal strategy, it does not, on its own, explain the timing of the motion or justify undue delay. Undue delay may be found where a party fails to act promptly under the circumstances. See Pruco Life Ins. Co. v. California Energy Dev., Inc., No. 18-CV-2280 DMS (AHG), 2020 WL 4345330, at *2 (S.D. Cal. July 29, 2020). Here, Plaintiff could have sought leave to amend shortly after receiving the conflict-of-interest policy and related documents in December 2024. Instead, Plaintiff waited almost seven months before filing the present motion. Additionally, Plaintiff fails to explicitly identify any specific documents or information produced after the initial disclosures that were essential to the new claims and theories asserted in the proposed SAC. (Mtn. Amend Dec. at 2.) Apart from Plaintiff’s post-deposition realization, the record does not support a justification for the delay. Accordingly, while the Court does not find that Plaintiff acted in bad faith, it concludes that the motion to amend is the product of undue delay. However, “undue delay, alone, is insufficient to justify denying a motion to amend.” Owens v. Kaiser Found. Health Plan, Inc., 244 F.3d 708, 712–13 (9th Cir. 2001). B. Prejudice to Opposing Party The Ninth Circuit has stated that, of the factors, “prejudice to the opposing party [] carries the greatest weight.” Eminence Capital, LLC v. Aspeon, Inc., 316 F.3d 1048, 1052 (9th Cir. 2003). The party opposing the amendment bears the burden of showing prejudice. DCD Programs, Ltd. v. Leighton, 833 F.2d 183, 186–87 (9th Cir. 1987). “Absent prejudice, or a strong showing o
