Plaintiff, ORDER

v.

Commissioner of Social Security Administration, Defendant. Attorney Maren Bam seeks permission to file an untimely appeal from a magistrate judge order which found she violated Federal Rule of Civil Procedure 11. Bam’s failure to follow the basic procedures for seeking review of such an order before petitioning the Ninth Circuit for mandamus is inexplicable, but the case-specific standard for extending deadlines narrowly suggests the court should allow the untimely appeal. Reaching the merits of the appeal, Bam recklessly failed to ensure the accuracy of her citations. But sua sponte Rule 11 sanctions must meet a higher bar than party-initiated ones, and there are not sufficient factual findings that Bam’s behavior satisfied that bar. The finding of a Rule 11 violation is vacated, as are most of the sanctions. Only those sanctions striking the opening brief and revoking Bam’s pro hac vice status in this case remain in place, although on a different basis than Rule 11. Shortly after this case was filed, it was referred to a magistrate judge for all pretrial proceedings. (Doc. 9.) That order told Bam the district judge was referring the case pursuant to 28 U.S.C. § 636(b)(1), which sets out procedures for seeking a district judge’s review of a magistrate judge’s order. (See Doc. 9.) On July 22, 2025, the assigned magistrate judge issued an order noting the opening brief signed and filed by Bam was “replete with citation-related deficiencies.” (Doc. 16 at 1.) The citations suggested Bam “may have used artificial intelligence” when drafting the brief. (Doc. 16 at 1.) The magistrate judge ordered Bam to “show cause why the Court should not impose sanctions under Rule 11 . . . for submitting non-existent cases and otherwise deficient case law citations to the Court.” (Doc. 16 at 4.) Bam’s response explained her firm “utilizes experienced, licensed attorneys in good standing with their state bar to assist with the preparation of . . . opening and reply briefs.” (Doc. 17 at 2.) The opening brief in this case had been “drafted by an attorney who owns and operates her own social security disability law practice” and was employed by Bam’s firm as an independent contractor starting in November 2024. (Doc. 17 at 3.) On May 9, 2025, Bam’s office circulated an announcement regarding artificial intelligence issued by the Chief Judge of the District of New Mexico. (Doc. 17 at 3.) That announcement stated in relevant part: “While acknowledging the potential benefits of AI, the Court has observed instances of AI-generated arguments and citations to non-existent cases, a practice that is strictly prohibited and may result in sanctions to uphold the integrity of the judicial system.” (Doc. 17-3 at 1.) Bam’s office asked the contract attorney to “respond to this email confirming that you have received it and acknowledged the information provided within it.” (Doc. 17-4 at 1.) That same day, the attorney responded, “I have received the email . . . and acknowledge the information provided within it.” (Doc. 17-4 at 1.) The contract attorney was drafting the opening brief in this case at around the same time she emailed her response. (Doc. 17 at 3-4.) On May 18, 2025, the attorney submitted the brief to “an on-staff supervising attorney” for internal review, the first layer of review at Bam’s firm. (Doc. 17 at 2-3.) During these reviews, supervising attorneys are tasked with reviewing “the brief’s legal arguments, formatting, and citations” to “ensure[] the brief is legally sound” and “spot-check[ing] the legal authorities and citations outlined in the brief.” (Doc. 17 at 2-3.) Bam performs a “Final Sign-off” before filing. (Doc. 17 at 3.) The supervising attorney purportedly reviewed the opening brief in this matter but failed to identify any of the troubling citations. (Doc. 17 at 4.) Bam then “personally reviewed and edited” the opening brief but also failed to identify the citation errors. (Doc. 17 at 3.) Given the extent of incorrect citations scattered throughout the opening brief (see Doc. 16), the reviews by the supervising attorney and Bam must have been extremely limited. A cursory “spot-check” of even a handful of the brief’s citations would have uncovered the errors. Bam does not explain how her review process could fail to this extent. Although she states she and the supervising attorney “were not on the same page regarding the firm’s procedure” (Doc. 17 at 4), that disconnect related to internal deadlines rather than standards of review (Doc. 17-8). It is undisputed the opening brief was filed despite its non-existent citations and that Bam was the only attorney who signed it. On receiving the magistrate judge’s order identifying the citation errors, Bam “initiated a thorough internal review of the brief . . . as well as other work submitted by [the same] contract writer.” (Doc. 17 at 4.) Bam also prepared a “citation correction table identifying the problematic citations, their intended propositions, and the accurate authorities that should have been cited” and requested leave to file an amended opening brief. (Doc. 17 at 6.) Despite acknowledging the errors were “deeply concerning and contrary to the standard of advocacy [Bam’s] firm strives to uphold,” Bam stated she had not “knowingly submitted false or non-existent citations” and did not “intend to mislead the Court or submit citations not grounded in valid legal authority.” (Doc. 17 at 1, 5.) On August 14, 2025, the magistrate judge ruled Bam had violated Rule 11 by filing the opening brief with incorrect and hallucinated citations. (Doc. 18.) In reaching that conclusion, the magistrate judge found “well over the majority of the citations” in the opening brief “were fabricated, misleading, or unsupported.” (Doc. 18 at 9.) Based on the number of errors, it was “apparent to [the magistrate judge] that [Bam] did not review the citations.” (Doc. 18 at 10-11.) And because Bam “failed to conduct any review whatsoever that [the cited cases] were valid or that the arguments she was making were legally tenable,” Bam’s “conduct squarely [ran] afoul of Rule 11’s mandate.” (Doc. 18 at 12.) For present purposes, two aspects of the sanctions order are particularly important. First, the magistrate judge noted the standard for sanctions under Rule 11 “is applied with particular stringency where . . . the sanctions are imposed on the court’s own motion.” (Doc. 18 at 13 (quoting United Nat. Ins. Co. v. R&D Latex Corp., 242 F.3d 1102, 1115-16 (9th Cir. 2001)).) In that context, sanctions are permissible only “in situations that are akin to a contempt of court.” (Doc. 18 at 13 (citations omitted).) According to the magistrate judge, that “akin to a contempt” standard was satisfied because the opening brief was “riddled with fabricated, misleading, or unsupported citations” such that without them, “entire sections of the [brief’s] ‘Analysis’ [were] nearly wholly unsupported, and clearly, there was no reasonable inquiry made into its contents.” (Doc. 18 at 14.) The second critical aspect of the magistrate judge’s sanctions order is an explicit finding that Bam had not acted in subjective bad faith. The magistrate judge explained she was not “go[ing] so far as to find [Bam] acted with subjective bad faith” but that Bam’s actions nonetheless “rise to the level of Rule 11 sanctions.” (Doc. 18 at 22.) Having found Bam’s citations violated Rule 11, the magistrate judge imposed six sanctions: 1. Revoking Bam’s pro hac vice status for this case; 2. Striking the opening brief; 3. Requiring Bam provide her client with a copy of the sanctions order; 4. Requiring Bam “write a letter to the three [District of Arizona] Judges to whom she attribute
