CONVENTION ON TAKING EVIDENCE WILLIAM IAN MARTIN BONAR, as an

individual and in his official capacity; and DOES 1 through 50, inclusive, [ECF No. 67] Defendants. Currently before the Court is Plaintiffs’ Motion for Issuance of Letter of Request for International Judicial Assistance Pursuant to the Hague Convention on Taking Evidence Abroad (“Motion”) [ECF No. 67], and Defendant’s Opposition to Plaintiffs’ Motion (“Opposition”) [ECF No. 70]. For the reasons set forth below, Plaintiffs’ motion to issue a letter of request is GRANTED I. Factual and Procedural Background On November 19, 2024, Plaintiffs initiated this action by filing a complaint against Defendant William Bonar and other defendants including Ian Robert Mackenzie and Samantha Mackenzie (“Compl”). ECF No. 1. On July 16, 2025, District Judge William Q. Hayes dismissed all defendants other than William Bonar for “lack of personal jurisdiction.” ECF No. 29. Plaintiffs filed their First Amended Complaint on September 25, 2025 (“FAC”). ECF No. 48. In the FAC, Plaintiffs asserted thirteen causes of action, including breach of fiduciary duty, tortious interference with contractual relations, tortious interference with business relations, misappropriation of trade secrets, and conspiracy to misappropriate trade secrets. ECF No. 48. On February 12, 2026, Plaintiffs filed this instant Motion, seeking “authorization to obtain oral deposition testimony under oath from two non-party witnesses” residing in the United Kingdom, Ian Robert MacKenzie and Samantha MacKenzie, and to inspect certain documents. ECF No. 67; ECF No. 67-1, at 13, 17, 19. The Court set a briefing schedule on February 13, 2026. ECF No. 68. Defendant timely filed his Opposition. See ECF No. 70. Plaintiffs did not file a Reply. See Docket. A. Plaintiffs’ Motion In their letter of request, Plaintiffs state that they seek sworn testimony from Ian Robert MacKenzie regarding the following topics: (1) His knowledge of William Ian Martin Bonar's past and current business ventures, including but not limited to any client lists and details of products currently being sold by William Ian Martin Bonar. (2) Communications between him and William Ian Martin Bonar regarding the Plaintiffs, the Plaintiff's products and the Plaintiff' employees when under William Ian Martin Bonar’s supervision[.] (3) His role in Wafer Fab Solutions Ltd and Semicon Solutions Ltd[.]1 1 These are allegedly Defendant’s new companies registered in the United Kingdom. See Motion, at 6; Declaration of Fletcher A. Robbe in Support of Motion for Issuance of Letter of Request (4) The dates William Ian Martin Bonar began operations of his new companies, Wafer Fab Solutions Ltd and Semicon Solutions Ltd. (5) His knowledge of the technology being used and sold by William Ian Martin Bonar. ECF No. 67-1, at 17. Plaintiffs state that they seek sworn testimony from Samantha MacKenzie regarding the following topics: (1) Her knowledge of William Ian Martin Bonar’s past and current business ventures, including but not limited to any client lists and details of products currently being sold by William Ian Martin Bonar. (2) Communications between her and William Ian Martin Bonar regarding the Plaintiffs, the Plaintiff's products and the Plaintiffs' employees when under William Ian Martin Bonar's supervision[.] (3) Her role in Wafer Fab Solutions Ltd and Semicon Solutions Ltd[.] (4) The dates William Ian Martin Bonar began operations of his new companies, Wafer Fab Solutions Ltd and Semicon Solutions Ltd. (5) Her knowledge of the technology being used and sold by William Ian Martin Bonar. ECF No. 67-1, at 19. Plaintiffs also request to inspect the following documents: Any and all documentation and communications, email or otherwise, regarding IP/technology since inception of the agreements in question to present. ECF No. 67-1, at 13. Plaintiffs argue that the requested information is relevant and necessary because: 1) it directly relates to identifying the technology being used in Defendant’s company and whether Defendant’s current clients were or are Plaintiffs’ clients; and 2) it shows whether Defendant now uses Plaintiffs’ technology. Motion at 7. Plaintiffs state that the two witnesses were “former relevant to these proceedings,” and “are now working with Defendant [] in his newly established company in the UK,” and as such “possess firsthand knowledge of material events” such as technology designs, products being sold by Defendant, and “documents taken from Plaintiffs’ company location in UK [including client lists and engineering schematics].” Motion at 7. Plaintiffs also allege that Ian Robert Mackenzie is now in partnership with Defendant in a new company registered in the United Kingdom, Wafer Fab Solutions, Ltd., and Plaintiffs believe and allege that Plaintiffs’ technology is being used without permission or authority. Id. at 6. Plaintiffs assert without explanation or support that the information sought is not unduly burdensome. Id. at 8. B. Defendant’s Opposition Defendant opposes both the deposition requests and the request to obtain documents. First, with regard to the deposition requests, Defendant argues that Plaintiffs are attempting to circumvent this Court’s jurisdictional ruling and obtain pre-trial discovery, which is not permitted in the United Kingdom. Opposition at 2, 10-13. Second, Defendant argues that all three discovery requests are overbroad and unduly burdensome and should not be permitted under federal law, the Hague Convention, or United Kingdom law. Id. at 2, 5-7, 13-14. Third, Defendant contends that the requested information is equally available from Defendant and therefore Plaintiff should not be allowed to seek the information from these non-parties. Id. at 2, 7-8. Finally, Defendant raises several additional concerns that he believes the Court should consider and that support his opposition. Id. at 8-9, 11-13. II. Legal Standard Federal Rule of Civil Procedure 28(b) and 28 U.S.C. § 1781(b)(2) authorize federal courts to issue letters rogatory (or letters of request) that enable a litigant in the United States to obtain non-party discovery from a foreign entity. See Wadeea v. Mercedes-Benz USA, LLC, 2025 WL 2417180, at *2 (S.D. Cal. Aug. 21, 2025); Viasat, Inc. v. Space Sys./loral, Inc., 2013 WL 12061801, at *2 (S.D. Cal. Jan. 14, 2013). A letter rogatory is a formal written request sent by a court to a foreign court. Wadeea, 2025 WL 2417180, at *2. “The issuing court does not need jurisdiction over the party from whom discovery is sought because it cannot compel compliance authority to enforce the letters rogatory or not.” McCarthy v. Johnson, 640 F. Supp. 3d 69, 77 (D.D.C. 2022) (quoting Lantheus Med. Imaging, Inc. v. Zurich Am. Ins. Co., 841 F. Supp. 2d 769, 782 (S.D.N.Y. 2012)). When determining whether to exercise its discretion to issue a letter rogatory, a court generally will not weigh the evidence sought from the discovery request, nor will it attempt to predict whether that evidence will actually be obtained. Viasat, 2013 WL 12061801, at *2; Gardner Denver, Inc. v. Accurate Air Eng'g, Inc., 2024 WL 6885484, at *2 (C.D. Cal. July 12, 2024). Rather, a court’s decision whether to issue a letter rogatory requires an application of Federal Rule of Civil Proc
