Advisory Committee on Evidence Rules Examines AI Evidence in Oct 2026 Mini-Conference

TL;DR:

The Advisory Committee on Evidence Rules held an October 15, 2026 mini-conference in Boston to discuss deepfakes and machine-generated evidence, focusing on proposed Federal Rules 901(c) and 707. The committee did not finalize new rules at that meeting, but the discussions signal potential future gatekeeping changes for AI evidence, including a two-step burden-shifting approach to authenticity and a requirement for pretrial notice when deepfakes are involved. Litigators should monitor how Rule 707 and Rule 901(c) evolve, consider how they would handle AI-generated evidence in disputes today, and begin aligning trial-readiness training with AI evidence scenarios. Objection Academy offers training concepts aligned with these evolving standards, including objection drills and evidence-ready simulations for AI-related disputes.

The timely development

On October 15, 2026 the Advisory Committee on Evidence Rules convened a Boston meeting to review how federal evidence rules should address artificial intelligence generated content, including deepfakes. The official agenda book confirms a dedicated track on “Deepfakes and the Federal Rules on Authenticity” and notes that the committee has been evolving its approach to AI in evidence since 2023. In particular, the committee discussed a proposed Rule 901(c) that would create a two-step burden-shifting framework for claims that evidence is fabricated by generative AI, and a contemplated refinement of Rule 707 addressing machine-generated evidence. The minutes show the committee’s intent to cover “generative artificial intelligence” and to require pretrial notice when a deepfake challenge is raised, with a view toward balancing gatekeeping with practical trial considerations. The October 15, 2026 agenda explicitly documents the ongoing deliberations, definitions, notice provisions, and the interplay between AI-authenticity questions and traditional rules for authentication and admissibility. This material provides a concrete, official snapshot of where federal evidence policy may head in the near term. (uscourts.gov)

What the rules proposals say and how they could affect trials

  • Rule 901(c) would introduce a specific path for deepfake challenges. A party contending that an item is fabricated by generative AI would need to present enough evidence to justify a court’s inquiry into fabrication. If that threshold is met, the burden would shift to the proponent to prove authenticity by a preponderance of the evidence. This is a significant shift from current practice where authentication standards are evaluated under existing Rule 901 and related authorities. The agenda book makes clear that the committee’s draft contemplates a two-step process and a definitional structure around “generative AI.” (uscourts.gov)
  • Rule 901(c) would also require pretrial notice of the intent to present evidence of fabrication, ensuring all parties have a fair opportunity to respond before trial. The notes discuss how flexible that notice should be, and whether to require written notice or permit court-ordered notice in lieu of a formal writing requirement. The debate signals the practical tension between early case management and trial-day surprises over AI-generated content. (uscourts.gov)
  • Rule 707, governing machine-generated evidence, remains a parallel focus. The mini-conference functionally tests whether a new rule is warranted and, if so, what form it should take, including how it interacts with existing authentication and reliability standards. While no final version was adopted at the October meeting, the discussions reflect a serious, near-term pathway for formalizing how courts treat AI-assisted outputs and “AI-in-the-loop” testimony in trials. (uscourts.gov)

Practical implications for trial teams today

  • Evidence strategy must anticipate possible gatekeeping changes. Even in the absence of a final rule, practitioners should prepare for possible requirements to address AI-generated content more explicitly at the pretrial stage, including potential Daubert-like considerations for the reliability of AI outputs. The committee’s work indicates a trend toward heightened scrutiny of AI-produced material, which could affect motions in limine, authentication disputes, and the admissibility of screenshots, transcripts, or other AI-delivered outputs. (uscourts.gov)
  • Discovery and pretrial practice should incorporate AI-specific considerations. If a party intends to rely on AI-generated evidence, counsel should consider how to document the provenance of the material, how to provide notice of deepfake claims, and how to structure a rapid in-trial response if authenticity is challenged. This may involve maintaining a clear record of AI tool usage, prompts, and outputs where relevant, and preparing to address prompt-level disclosure issues in discovery disputes. The agenda’s emphasis on “notice” and a two-step authentication framework underscores the growing importance of early AI evidence planning. (uscourts.gov)
  • Trial-readiness training should incorporate AI-evidence drills. As courts experiment with Rule 707 and Rule 901(c), litigators will benefit from practicing objections to AI-generated material, authenticating AI outputs, and handling deepfake challenges in live settings. Objection Academy can be a practical companion in this shift, offering drills and simulations that map to authenticating AI-produced evidence, articulating objections, and rehearsing response strategies in a trial-ready format.

How to prepare as a trial team

  • Track the evolving rulemaking. The October 15, 2026 agenda confirms ongoing consideration of Rule 901(c) and Rule 707. Firms should monitor subsequent Standing Committee actions and any published final rules or formal republications. The official agenda book remains a primary, citable source for the state of the proposal as of October 2026. (uscourts.gov)
  • Update objections and authentication playbooks. Given the proposed shifts, counsel should revisit boilerplate objections for authenticity and consider creating standard templates for raising deepfake concerns under Rule 901(c) once (or if) a final rule is published. Practitioners should also contemplate how to introduce AI-factual disputes at pretrial conferences to avoid last-minute evidentiary issues.
  • Integrate AI-evidence drills into continuing education. For trial teams, incorporating AI-focused drills into MCLE or firm training can help preserve trial readiness in the face of changing standards. Objection Academy’s training approach—emphasizing objection drills, evidence-ready simulations, and practical courtroom practice—aligns with the need to practice AI-evidence scenarios now and in the near future.

Objection Academy alignment

Objection Academy remains a resource for trial teams navigating evolving evidentiary standards, including AI-generated evidence. The program’s emphasis on objection drills, evidence training, and realistic trial simulations supports lawyers preparing for Rule 901(c) style challenges and the kinds of ethical and practical decisions that arise when AI-generated content enters discovery and the courtroom. In jurisdictions where MCLE or other credits apply, Objection Academy modules can be integrated into continuing education, helping teams stay courtroom-ready as Rule 707 and Rule 901(c) considerations mature.

Next steps and timeline

  • Expect further developments in 2026 and early 2027. The October 2026 mini-conference signals that the Advisory Committee intends to continue refining AI-related rules before any formal publication or republication. Litigators should monitor updates from the Advisory Committee on Evidence Rules and the Standing Committee for announcements on final rules, republications, or transitional guidance. The October 15, 2026 agenda book remains a key reference point for the committee’s current thinking and next steps. (uscourts.gov)
  • Prepare for potential changes by building internal processes now. Even without a final rule, counsel should begin drafting internal protocols for handling AI-generated evidence, including how to raise, respond to, and document deepfake concerns, and how to structure pretrial notices consistent with evolving authorities.
