1 2 3 4 UNITED STATES DISTRICT COURT 5 NORTHERN DISTRICT OF CALIFORNIA 6 7 CAITLIN CHALMERS, Case No. 25-cv-05083-JSC

8 Plaintiff, ORDER RE: DEFENDANT’S MOTION 9 v. FOR JUDGMENT ON THE PLEADINGS 10 BRIAN CAYNE, Re: Dkt. No. 10 Defendant. 11

12 13 Plaintiff sues Brian Cayne arising from the dissolution of their romantic relationship. (Dkt. 14 No. 1-1.)1 Now pending before the Court is Mr. Cayne’s motion for judgment on the pleadings. 15 (Dkt. No. 10.) Having carefully considered the parties’ submissions, and with the benefit of oral 16 argument on October 2, 2025, the Court GRANTS Mr. Cayne’s motion for judgment on the 17 pleadings. California Civil Code Sections 43.4 and 43.5 bar Plaintiff’s claims for breach of 18 contract, breach of implied contract, fraud, promissory estoppel, and negligent misrepresentation. 19 Plaintiff does not allege sufficient facts to state claims for dissolution of partnership and 20 community assets, breach of fiduciary duty, intentional infliction of emotional distress, or 21 conversion. And Plaintiff’s claim for imposition of constructive trust fails because it is an 22 equitable remedy, not a cause of action. 23 BACKGROUND 24 Plaintiff, a Canadian citizen, and Mr. Cayne, a California resident, began a romantic 25 relationship in fall 2021. (Dkt. No. 1-1 ¶¶ 3, 5, 6.) At that time, Plaintiff lived with her two-year- 26 old son in California and earned approximately $300,000 annually in her job. (Id. ¶ 6.) Plaintiff 27 1 alleges Mr. Cayne asked her to give up her homes in California and Canada to live with him, and 2 to leave her job to be a stay-at-home parent to her son and his son. (Id. ¶ 8.) In return, Mr. Cayne 3 allegedly promised Plaintiff he would support her “indefinitely,” purchase a home they would 4 jointly own, share ownership and profits of any future investments, and allow her to “use whatever 5 funds she needed for anything she wanted.” (Id. ¶¶ 8, 20.) When Plaintiff hesitated, Mr. Cayne 6 “assured [Plaintiff] he loved her, that he wanted to marry her, and that she could trust him about 7 the financial arrangement he was offering.” (Id. ¶ 8.) As assurance Mr. Cayne was “standing by 8 his promises,” he placed $100,000 in her bank account. (Id.) 9 By around March 2022, Plaintiff had sold her home in Canada, given up her apartment in 10 California, left her job, “got rid of most of her belongings,” and moved in with Mr. Cayne. (Id. ¶ 11 9.) Plaintiff and Mr. Cayne “were engaged and he gave her an engagement ring.” (Id.) Plaintiff 12 alleges Mr. Cayne’s behavior then “turned dark and controlling.” (Id. ¶ 10.) Although Plaintiff 13 needed rest because she was undergoing cancer treatment, Mr. Cayne would wake her up in the 14 middle of the night and “berate her and tell her that she was selfish if she protested.” (Id.) Mr. 15 Cayne pressured her to drink, allowed her car to be towed and told her not to retrieve it, got upset 16 if she left home without him, did not want her to speak to her friends, and searched her phone. 17 (Id.) Eventually, Mr. Cayne decided to purchase a home in Canada; he sent Plaintiff and her son 18 to Canada, where he “was to arrive shortly thereafter.” (Id. ¶ 11.) However, around July 27, 19 2022, Mr. Cayne informed Plaintiff “he was breaking off the relationship.” (Id. ¶¶ 11, 19.) 20 Plaintiff sued Mr. Cayne in California Superior Court asserting claims for breach of oral 21 contracts for property and support, breach of implied contract, dissolution of partnership and 22 community assets, breach of fiduciary duty, fraud, promissory estoppel, negligent 23 misrepresentation, intentional infliction of emotional distress, conversion, and imposition of 24 constructive trust. (Id. at 9-28.) Plaintiff sought at least $500,000 in general damages, at least 25 $8,000,000 in special damages, exemplary and punitive damages, and other relief. (Id. at 28-29.) 26 Mr. Cayne removed the case to this Court based on diversity jurisdiction and answered the 27 1 complaint.2 (Dkt. Nos. 1, 3.) 2 Mr. Cayne now moves for judgment on the pleadings. (Dkt. No. 10.) 3 DISCUSSION 4 “After the pleadings are closed—but early enough not to delay trial—a party may move for 5 judgment on the pleadings.” Fed. R. Civ. P. 12(c). “Judgment on the pleadings is proper when 6 the moving party clearly establishes on the face of the pleadings that no material issue of fact 7 remains to be resolved and that it is entitled to judgment as a matter of law.” Hal Roach Studios, 8 Inc. v. Richard Feiner & Co., Inc., 896 F.2d 1542, 1550 (9th Cir. 1989) (citation omitted). “A 9 motion for judgment on the pleadings under Rule 12(c) is subject to the same standard as a Rule 10 12(b)(6) motion to dismiss.” Kawasaki Jukogyo Kabushiki Kaisha v. Rorze Corp., 782 F. Supp. 11 3d 836, 850 (N.D. Cal. 2025) (citing Dworkin v. Hustler Mag., Inc., 867 F.2d 1188, 1192 (9th Cir. 12 1989)). So, when considering a motion under Federal Rule of Civil Procedure 12(c), the Court 13 “must accept the facts as pled by the nonmovant.” Cafasso, U.S. ex rel. v. Gen. Dynamics C4 Sys., 14 Inc., 637 F.3d 1047, 1053 (9th Cir. 2011) (citation omitted). 15 I. BREACH OF ORAL CONTRACTS FOR PROPERTY AND SUPPORT, BREACH OF IMPLIED CONTRACT, FRAUD, PROMISSORY ESTOPPEL, AND 16 NEGLIGENT MIS REPRESENTATION (CAUSES OF ACTION I, II, III, VI, VII, AND VIII) 17 A. California Civil Code Sections 43.4 and 43.5 18 At common law, a breach of promise of marriage action “held out the promise of ‘a large 19 assortment of tort and contract damages’ in addition to any actual property with which the plaintiff 20 may have parted.” See Askew v. Askew, 22 Cal. App. 4th 942, 960 (1994). However, “to 21 eliminate [this] class of lawsuits which were frequently used for extortion, [and] which promoted 22 fraud and perjury and encouraged marriages motivated by fear of a lawsuit instead of love,” the 23 California Legislature enacted Civil Code Section 43.5. See Boyd v. Boyd, 228 Cal. App. 2d 374, 24 377 (1964). Under Section 43.5, “[n]o cause of action arises for . . . breach of promise of 25 marriage.” Cal. Civ. Code § 43.5(d). While Section 43.5 “obviously prohibited (and still 26

27 2 While the complaint alleges Mr. Cayne is a California resident, his declaration in support of 1 prohibits) lawsuits seeking contract damages for the emotional pain of a broken engagement,” it 2 remained unclear “whether it also prohibited tort lawsuits based on fraudulent or deceitful 3 promises to marry or live as a married couple.” Askew, 22 Cal. App. 4th at 954. So, the 4 California Legislature enacted Section 43.4, which states, “A fraudulent promise to marry or 5 cohabit after marriage does not give rise to a cause of action for damages.” Cal. Civ. Code § 43.4. 6 Sections 43.4 and 43.5 bar Plaintiff’s claims for breach of oral contract for property and 7 support, breach of implied contract, promissory estoppel, fraud, and negligent misrepresentation.
