11 Plaintiff, ORDER GRANTING PLAINTIFF’S 12 v. MOTION FOR LEAVE TO AMEND COMPLAINT 13 THERMO FISHER SCIENTIFIC INC.;

ADRIAN MOORES, an individual; and 14 (ECF No. 23) DOES 1 through 10, inclusive,

15 Defendants. 16 17 Presently before the Court is Plaintiff Heidi Brunell’s Motion for Leave to Amend 18 Complaint (“Mot.” ECF No. 23). Also before the Court is Defendants Thermo Fisher 19 Scientific Inc.’s and Adrian Moores’s Opposition to Plaintiff’s Motion for Leave (“Opp’n,” 20 ECF No. 29) and Plaintiff’s Reply to Opposition to Motion for Leave to Amend Complaint 21 (“Reply,” ECF No. 35). Plaintiff seeks to amend the Complaint (“Compl.,” ECF No. 1) in 22 light of evidence disclosed by Defendants after the deadlines for initial disclosures and 23 amending pleadings. Mot. at 2. For the reasons set forth below, the Court GRANTS 24 Plaintiff’s Motion (ECF No. 23). 25 LEGAL STANDARD 26 Motions to amend are governed by Federal Rule of Civil Procedure 15, which, as 27 relevant here, provides that a party may amend its pleading once as a matter of course 28 within twenty-one days of service of a motion under Rule 12(b) but otherwise must obtain 1 either leave of the court or the written consent of the adverse party in order to amend. Fed. 2 R. Civ. P. 15(a); Eminence Capital, LLC v. Aspeon, Inc., 316 F.3d 1048, 1051 (9th Cir. 3 2003) (citing Fed. R. Civ. P. 15(a)). 4 The general policy provided by Rule 15(a)(2) that the court should freely give leave 5 “when justice so requires” is “to be applied with extreme liberality.” Eminence Capital, 6 LLC, 316 F.3d at 1051 (quoting Owens v. Kaiser Found. Health Plan, Inc., 244 F.3d 708, 7 712 (9th Cir. 2001)). Accordingly, leave should be “freely given” absent “undue delay, 8 bad faith or dilatory motive on the part of the movant, repeated failure to cure deficiencies 9 by amendments previously allowed, undue prejudice to the opposing party by virtue of 10 allowance of the amendment, futility of amendment, etc.” Foman v. Davis, 371 U.S. 178, 11 182 (1962); see also Yakama Indian Nation v. State of Wash. Dept. of Revenue, 176 F.3d 12 1241, 1246 (9th Cir. 1999) (“Amendment under the Federal Rules of Civil Procedure 13 should be granted unless amendment would cause prejudice to the opposing party, is sought 14 in bad faith, is futile, or creates undue delay.”) (internal quotation omitted). Of these 15 factors, prejudice is the most important. Eminence Capital, LLC, 316 F.3d at 1052. “The 16 party opposing amendment bears the burden of showing prejudice.” DCD Programs, Ltd. 17 v. Leighton, 833 F.2d 183, 187 (9th Cir. 1987). 18 In deciding whether to grant leave to amend, a trial court “should be guided by the 19 underlying purpose of Rule 15(a) . . . to facilitate decisions on the merits, rather than on 20 technicalities or pleadings.” James v. Pliler, 269 F.3d 1124, 1126 (9th Cir. 2001) (citing 21 United States v. Webb, 655 F.2d 977, 979–80 (9th Cir. 1981)). Absent prejudice or a strong 22 showing of the other Foman factors, there is a presumption in favor of granting leave to 23 amend. Eminence Capital, LLC, 316 F.3d at 1052 (internal citation omitted). 24 / / / 25 / / / 26

27 1 Here, Plaintiff has not exercised her right to amend as a matter of course; however, Plaintiff filed her 28 Motion after the cut-off for amending pleadings pursuant to the Scheduling Order (ECF No. 15) in this 1 ANALYSIS 2 Plaintiff seeks to amend the Complaint to add claims for: (1) national origin as a 3 protected basis for discrimination, (2) failure to provide equal pay under Cal. Lab. Code 4 § 1197.5, and (3) non-compliance with Cal Lab. Code §1198.5. Mot. at 1. Plaintiff asserts 5 that leave to amend is warranted under Federal Rule of Civil Procedure 15(a) because 6 Defendants failed to comply with their discovery obligations under Rule 26(a)(1)(A)(ii). 7 Mot. at 2. Specifically, Defendants failed to produce “key evidence,” including an 8 arbitration agreement and emails “bearing upon Plaintiff’s burden to prove discriminatory 9 motive and statutory violations under Labor Code §§ 1198.5 and 1197.5,” ECF No. 23-1 10 (“Mem.”) at 4, before the deadlines for initial disclosures and to amend pleadings on July 11 8, 2025, and July 17, 2025, respectively, had passed, Mot. at 1–2. Defendants assert that 12 the Court should deny leave to amend due to Plaintiff’s own undue delay and that 13 amendment is futile. Opp’n at 1. 14 To determine whether Plaintiff’s Motion should be granted, the Court now considers 15 each of the five Foman factors in turn. 16 I. Prejudice 17 Plaintiff contends that granting leave to amend would not prejudice Defendants 18 because discovery is at an early stage, a trial date has not been set, and Defendants have 19 not agreed to engage in substantive discovery. Mem. at 3. Rather than argue that they 20 would suffer prejudice from amendment, Defendants instead argue that Plaintiff has not 21 suffered prejudice since she “received her acknowledgement of the arbitration agreement 22 prior to litigation, received the complete agreement prior to resolution of the appropriate 23 forum for this matter, and has self-admittedly suffered no prejudice due to any purported 24 delay.” Opp’n at 6. 25 However, the proper focus is prejudice to Defendants “by virtue of allowance of 26 amendment,” not prejudice to Plaintiff. See Foman, 371 U.S. at 182. “In considering the 27 potential prejudice of the amendment, the Court considers whether the amended complaint 28 would ‘greatly change the parties’ positions in the action, and require the assertion of new 1 defenses.’” Kohler v. Flava Enterprises, Inc., No. 10-CV-730-IEG NLS, 2011 WL 2 666899, at *2 (S.D. Cal. Feb. 17, 2011) (quoting Phoenix Solutions, Inc. v. Sony Elec., Inc., 3 637 F. Supp. 2d 683, 690 (N.D. Cal. 2009)). Relevant considerations include, for example, 4 whether the proposed amendment adds additional claims or defenses, see id.; whether the 5 proposed amendment is being sought after the cutoff date for such motions, see Dep’t of 6 Fair Emp. & Hous. v. L. Sch. Admission Council, Inc., No. C-12-1830 EMC, 2013 WL 7 485830, at *5 (N.D. Cal. Feb. 6, 2013) (citations omitted); and whether discovery already 8 has closed or will imminently close, see id. (citations omitted). 9 Defendants advance no such arguments here. See generally Opp’n. Although 10 Plaintiff’s proposed amended complaint adds additional claims, as the Parties have stated, 11 the case is in its infancy and discovery is ongoing. Because Defendants have not identified 12 any prejudice they would suffer as a result of amendment, the Court finds that Defendants 13 have failed to show that this factor weighs in favor of denying Plaintiff’s Motion.
