Petition for Writ of Mandamus to the United States District Court for the Northern District of Texas USDC No. 4:21-CR-5-1 ______________________________

Before Southwick, Duncan, and Engelhardt, Circuit Judges. Per Curiam: Following two tragic airplane crashes that killed hundreds, the Department of Justice investigated Boeing for concealing safety information related to the crashes. It then charged Boeing with conspiracy to defraud the United States. The Department later entered into a non-prosecution agreement (NPA) with Boeing on the condition that Boeing pay $1.1 billion in fines and undertake remedial actions. The district court granted the Department’s motion to dismiss the prosecution. Family members of the crash victims unsuccessfully challenged the NPA and the dismissal in the district court under the Crime Victims’ Rights Case: 25-11253 Document: 121-1 Page: 2 Date Filed: 03/31/2026

25-11253 c/w No. 25-11254

Act (CVRA), 18 U.S.C. § 3771 et seq. The families then sought mandamus relief in our court. We agree with the district court that the Department did not violate the families’ rights under the CVRA. Accordingly, we DENY the petitions for writ of mandamus. I In October 2018, Lion Air Flight 610 crashed shortly after takeoff in Indonesia, killing 189 passengers and crew. In March 2019, Ethiopian Airlines Flight 302 crashed shortly after takeoff in Ethiopia, killing 157 passengers and crew. Both planes were Boeing 737 MAX airliners. The crashes were caused by pilots’ unfamiliarity with Boeing’s changes to the 737 MAX’s Maneuvering Characteristics Augmentation System (MCAS). See In re Ryan, 88 F.4th 614, 618 (5th Cir. 2023). In response to the crashes, the Department of Justice launched a two-year investigation into Boeing. In February 2020, a representative of the Flight 302 crash victims’ families contacted the Department, which told them that Boeing was not currently under criminal investigation. The Department later apologized for failing to meet and confer with the families, claiming it was caused by “a regrettable and inadvertent internal miscommunication.” In January 2021, the Department charged Boeing with conspiracy to defraud the United States under 18 U.S.C. § 371, alleging that two Boeing employees had intentionally misled the FAA regarding changes to the MCAS system. The same day, the Department filed a Deferred Prosecution Agreement (DPA) it had negotiated with Boeing, in which Boeing admitted responsibility for the acts charged. The district court approved the DPA a few weeks later.

In December 2021, victims’ families moved to set aside the DPA under the CVRA. In February 2023, the district court denied their motion. It found that, although the Department had violated the CVRA by denying the families’ right to confer prior to reaching an agreement with Boeing, see 18 U.S.C. § 3771(a), it had done so not out of bad faith but due to “legal error.” United States v. Boeing Co., 655 F. Supp. 3d 519, 534 (N.D. Tex. 2023). That error, the court explained, was the Department’s mistaken belief that the crash victims were not “crime victims” under the CVRA. Ibid.; see 18 U.S.C. § 3771(e)(2)(A) (defining “crime victim” as “a person directly and proximately harmed as a result of the commission of a Federal offense or an offense in the District of Columbia”). The court also held it lacked authority to review or modify the terms of a DPA. Boeing, 655 F. Supp. 3d at 530–32. The families then filed a mandamus petition in our court. See 18 U.S.C. § 3771(d)(3) (“If the district court denies the relief sought, the movant may petition the court of appeals for a writ of mandamus.”). A panel held mandamus was premature. See Ryan, 88 F.4th at 627. It also noted that district courts “lack authority to exercise substantive review over DPAs.” Id. at 621. The panel did not, however, appear to resolve whether courts have authority to set aside DPAs altogether. See id. at 629–30 (Clement, J., concurring). In May 2024, the Department notified the district court that Boeing had breached the DPA by “failing to design, implement, and enforce a compliance and ethics program to prevent and detect violations of the U.S. fraud laws throughout its operations.” In May 2025, the Department held a video call with the victims’ families about its renewed case against Boeing. The Department told the families it was considering resolving the case through a motion to dismiss and a non-prosecution agreement (NPA). It explained that an NPA meant it

would agree not to prosecute Boeing, which would “require the Department to move to dismiss the charge pending against Boeing.” In exchange, Boeing would agree to “various undertakings, such as paying a penalty, improving compliance, etc.” The Department would agree not to revive the case unless it determined that Boeing had breached the NPA. The families had mixed opinions about the proposed NPA. In response to some concerns, the prosecution assured the families that their attorneys could “talk to [them] about the legal authority a judge has to deny the government’s motion to dismiss.” It also told the families that any NPA with Boeing would include a provision stating that if Boeing breached the NPA, “the Department could refile the charge and prosecute the case, notwithstanding the passage of time.” Finally, the prosecution stated it would “support the victims’ families right to be heard in front of Judge O’Connor” while he was considering whether to grant the motion to dismiss. About two weeks later, the prosecution and Boeing signed an NPA in line with the one it had discussed with the families. The finalized NPA and its attachments contained numerous references to the earlier DPA. One of the NPA’s provisions required Boeing to agree that if it breached the NPA, it could be prosecuted for conduct “not time-barred by the applicable statute of limitations on the date of the signing of this [NPA].” The Department then filed a motion to dismiss that included the in-effect NPA. The families asked the district court to deny the motion, citing (1) their previous objections to the DPA, (2) the Department’s alleged failure to meet and confer with them about the NPA, and (3) the NPA’s alleged betrayal of the public interest. The district court granted the motion to dismiss, holding the Department had not “acted with bad faith” and had “given more than mere conclusory reasons for its dismissal.” United States v. Boeing Co., No. 4:21-CR-5, 2025 WL 3095958, at *5 (N.D. Tex. Nov. 6, 2025).

4 Case: 25-11253 Document: 121-1 Page: 5 Date Filed: 03/31/2026

In response, the families filed two mandamus petitions in our court. The first reasserts their previous objections to the 2021 DPA.
