AI Litigation Briefing — September 22, 2026
Updated: Sep 26
Artificial intelligence moved deeper into litigation and legal operations this week, but the most consequential developments were not about novelty. They were about accountability. A Canadian province filed a cross-border lawsuit against an AI provider; a federal appellate court proposed an explicit human-verification requirement for generative-AI-assisted filings; courts continued to confront defective AI-related submissions; the federal judiciary expanded its policy work; and major law firms and technology providers pushed agentic systems further into legal workflows.
For managing partners, general counsel, litigators and legal-innovation leaders, those events belong in the same governance picture. The practical question is no longer simply whether an AI tool was used. It is whether the organization can identify the system, source material, permissions, human reviewer, decision point, exception, final version and evidence trail when the workflow is later challenged.
This September 22, 2026 edition ranks ten developments from the September 14-21 intake window for their litigation relevance, recency, NY-ON and cross-border significance, operational impact and AI GRC value. The ranking is an editorial prioritization for this briefing, not a legal conclusion. Every item distinguishes allegations from findings, proposals from operative rules, and product claims from independent evidence.
This is an honest AI disclosure. This briefing presents my analysis, as Pouya Shafabakhsh, from the perspective of AI governance, risk, compliance, and AI litigation. For the convenience of legal professionals and busy executives, this page also includes a podcast. The written briefing on this page is the controlling substantive analysis; a verbatim transcript is not currently available.
I. British Columbia Sues OpenAI Over the Tumbler Ridge School Shooting
British Columbia filed a lawsuit in U.S. federal court in California against OpenAI and Sam Altman arising from the February 2026 Tumbler Ridge school shooting. OpenAI disputes the allegations and says it maintains safeguards intended to identify serious threats and cooperate with authorities when an imminent, credible risk is identified. Separate family litigation has also been reported. At this stage, the province's allegations are allegations in a newly filed complaint; the court has not found negligence, causation, breach of a legal duty, or liability.
Litigation AI GRC analysis
The Litigation AI GRC question is reconstructability of a safety-escalation process. If the dispute reaches discovery or expert evidence, relevant records may include risk classifications, system and policy versions, alerts, reviewer actions, account restrictions, escalation thresholds, exception handling, and later remediation. The governing authority framework supports treating preservation, evidence integrity, cross-border data handling, privacy, and governance benchmarks as separate legal and technical lanes rather than converting NIST or ISO controls into binding law. For Ontario and New York legal leaders, the transferable lesson is narrower than the allegations: when an organization represents that a high-risk AI control exists, it benefits from being able to show what the control was designed to do and what actually happened in the event. Counsel can then determine what must be preserved or produced under the governing forum, protective order, privilege analysis, and discovery rules. The control objective is a reliable contemporaneous record, not a retrospective narrative assembled after a crisis.
II. Tenth Circuit Proposes Human-Verification Certification for GenAI-Assisted Filings
The Tenth Circuit opened public comment on proposed 2027 revisions that would add generative-AI language to Rule 46.5. The proposed text would require a human to review a filing prepared with generative-AI assistance and independently verify cited authorities, quotations, citations, legal analysis, and compliance with applicable rules and ethical duties. Public comment remains open through October 18, 2026. The proposal is therefore a live rulemaking development, not current law, and it does not govern New York, Ontario, or other federal circuits merely because it may be useful as a comparator.
Litigation AI GRC analysis
The legal-status distinction is central. New York Part 161 states that attorneys and parties generally should not be required to disclose AI use merely because AI assisted in preparing a court paper, while permitting courts or parts to adopt the Appendix A model verification rule. Ontario's O. Reg. 275/26, effective September 1, 2026, is technology-neutral and requires authenticity and quotation-accuracy certification for factums and quotation-accuracy certification for expert reports. The Federal Court of Canada has a separate AI-declaration regime for covered litigation documents. Those are different systems and should not be merged into a fictional North American rule. As a governance benchmark, the Tenth Circuit proposal nevertheless illustrates what a defensible release record can look like: authoritative source checks, quotation comparison, a named human reviewer, exception resolution, and approval of the exact filed version. Firms can design those controls without claiming that the proposal is already binding.
III. State Farm Lawyer Fined $999.99 Over False Citations
A Los Angeles judge ordered a lawyer representing State Farm to pay a $999.99 sanction after court papers included seven nonexistent cases generated through an AI tool, Reuters reported. The ruling concerns identified filing conduct by counsel. It does not decide the merits of the underlying insurance dispute, and it should not be presented as a general prohibition on AI-assisted legal work. The event is significant because fabricated authority reached a filed document despite the continuing responsibility of the human lawyer who signed and submitted it.
Litigation AI GRC analysis
The operational lesson is that a polished final read is not the same as source verification. A release process can separately test whether each authority exists, whether the citation is accurate, whether a quotation reproduces the source, whether a paraphrased proposition is supported, and whether the authority fits the relevant jurisdiction and procedural posture. That calibration is consistent with New York professional duties, Part 161's verification framework where adopted, and Ontario's September 1 quotation-accuracy rule without treating a California sanction as binding in New York or Ontario. One non-testifying control that can sit immediately before filing is a Shadow AI Audit before Court filing: a targeted pre-release review of authority existence, quotation fidelity, record citations, procedural posture, source traceability, and document coherence. It does not replace counsel's judgment, signature responsibility, or court-specific obligations; it is an additional quality-control layer designed to catch defects before the filed version becomes the evidence of the workflow.
IV. U.S. Judiciary Expands Its AI Work While Reaffirming Human Accountability
The Administrative Office of the U.S. Courts reported further Judicial Conference work on artificial intelligence on September 17. Reuters reported that a 24-member judiciary task force has examined more than 60 AI-related issues and made about 30 recommendations. Existing federal judiciary guidance emphasizes that judges remain responsible for judicial decisions even when AI is used for bounded administrative or support tasks. The update is policy work, not a single nationwide rule requiring lawyers to disclose AI in every federal filing.
Litigation AI GRC analysis
For legal organizations, the useful governance distinction is function and consequence rather than a binary 'AI/no AI' label. Administrative assistance, knowledge search, drafting, research, eDiscovery triage, evidence analysis, client-facing automation, and decision support can have different confidentiality, verification, access, logging, human-approval, and escalation requirements. AI GRC Framework Architecting can convert those distinctions into a controlled operating model: approved use cases, prohibited data flows, risk tiers, accountable owners, evidence requirements, vendor controls, incident handling, and jurisdiction overlays. NIST AI RMF and ISO/IEC 42001 are governance benchmarks, not binding law unless incorporated by a controlling instrument. That separation matters for managing partners because a framework is strongest when it distinguishes legal duties from internal policy and voluntary control design instead of presenting every good practice as a mandate.
V. Newly Public Statements Enter the OpenAI-News Publishers Fair-Use Fight
News publishers litigating against OpenAI and Microsoft are relying on newly public internal statements that they say bear on the defendants' fair-use positions. Reuters reports that the defendants continue to contest the plaintiffs' interpretation and maintain their legal defenses. The newly public material is evidence offered in active litigation, not a final judicial finding that training is infringing or that fair use does or does not apply. The legal questions remain case-specific and depend on the record, statutory doctrine, and the claims actually before the court.
Litigation AI GRC analysis
For IP, corporate, and M&A teams, the governance significance is that internal records can become litigation evidence. Data-acquisition decisions, licensing assumptions, product statements, training-source discussions, filtering choices, testing records, and market-impact assessments may later be compared against technical logs and external representations. The governing U.S. copyright framework includes Title 17 U.S.C. as binding U.S. copyright law and keeps governance frameworks separate from the legal merits. A defensible enterprise record therefore does not require suppressing internal debate; it benefits from accurate versioning, clear decision ownership, preservation of material approvals, and separation of legal conclusions from technical observations. In procurement or transaction diligence, teams can apply the same discipline to vendor representations, indemnity scope, training-data descriptions, model-change notices, and known limitations without assuming that one pending case resolves the rights position of every model or dataset.
VI. Florida Appeals Court Warns About 'AI Slop' Without Finding Fake Citations
In Lisandrillo v. Palozzi, Florida's Fourth District Court of Appeal denied a petition and wrote separately about what it described as apparent 'AI slop.' The court emphasized that the problem before it was not fabricated citations: the cited cases existed. Instead, the filings were criticized as unfocused, false, frivolous, and lacking meaningful professional judgment. The court suspected components and ordered counsel to show cause why sanctions should not issue, directing that the response itself be filed without AI. The opinion did not finally establish that AI authored the papers and did not impose the contemplated sanction within that opinion.
Litigation AI GRC analysis
The governance lesson is that citation verification is necessary but not sufficient. A document can cite authentic authorities and still fail because its reasoning is irrelevant, contradictory to the record, disproportionate, or professionally unusable. That distinction aligns with the separate duties of candour, competence, source verification, and supervision. For NY and Ontario firms, a release gate can therefore have two different tests: source integrity and substantive quality. The second asks whether a responsible lawyer has actually adopted the reasoning, tested it against the record, removed unsupported claims, and confirmed that the submission answers the procedural question before the court. The Florida opinion is not binding in New York or Ontario, but it is a useful warning against reducing AI quality control to a citation checker.
VII. Workday AI Hiring Discrimination Case Moves Into Class-Certification Fight
Applicants challenging Workday's AI-enabled hiring tools have asked a federal judge in California to certify proposed classes alleging discriminatory effects. Reuters reports that plaintiffs contend the challenged screening process disproportionately affected Black, female, older, and disabled applicants, while Workday denies wrongdoing and says its tools evaluate job qualifications rather than protected traits. The present procedural question is class certification. No court has made a class-wide finding that Workday or its customers discriminated, and the defendants retain their factual and legal defenses.
Litigation AI GRC analysis
Class litigation can make AI evidence architecture unusually important because commonality and causation may turn on what was shared across deployments and what varied by employer, configuration, data, decision path, or human intervention. Governance records can include model versions, feature configuration, validation methods, outcome monitoring, change logs, notices, overrides, and deployment-specific controls. Fairness and governance frameworks do not convert statistical testing into a predetermined legal conclusion; they support disciplined evidence handling while governing discrimination law and class-action rules remain separate. Where a dispute genuinely requires technical expert evidence, a Judicial Forensic AI Audit during a legal dispute may be scoped, subject to the governing qualification, disclosure, independence, and admissibility rules, as an Expert Witness or Jointly Retained engagement. The purpose is to test the actual system and evidence, not to assume bias or vindicate either side before the analysis is performed.
VIII. Ninth Circuit Narrows DMCA Theory in GitHub Copilot AI-Code Case
In Doe v. GitHub, Inc., the Ninth Circuit affirmed dismissal of a Digital Millennium Copyright Act claim brought by software developers who alleged that GitHub Copilot and OpenAI Codex reproduced code without copyright-management information. The panel reasoned that the challenged outputs did not remove copyright-management information from an existing work; they were generated works that had not previously contained that information. The court expressly distinguished that DMCA theory from traditional copyright infringement and did not decide whether similarities between code and copyrighted code could support infringement. Reuters reports that open-source licensing claims continue. The decision therefore narrows one statutory theory; it does not declare AI training generally lawful, resolve fair use, or dispose of every licensing claim.
Litigation AI GRC analysis
For IP, patent-adjacent software diligence, corporate transactions, and M&A, the control lesson is to separate legal theories and evidence sets. Copyright-management-information handling, source-code provenance, open-source license terms, training rights, output similarity, and contractual representations are related but not interchangeable questions. The governing U.S. copyright framework includes Title 17 U.S.C. as binding U.S. copyright law and treats technical provenance controls as governance evidence rather than legal conclusions. Transaction teams evaluating an AI-enabled target can therefore ask which repositories, licenses, attribution terms, fine-tuning sources, and code-generation controls exist, while litigation teams preserve the evidence necessary to test the claim actually pleaded. A clean provenance register will not decide infringement, but it can materially improve the ability to investigate, value, defend, or remediate an IP risk without collapsing distinct doctrines into one generic 'AI copyright' category.
IX. Corporate Counsel Group Says Rival Trained Legal AI on Its Copyrighted Materials
The Association of Corporate Counsel sued The Suite, Inc., which operates The L Suite, alleging that its lawyer-focused Lloyd chatbot used ACC copyrighted materials and that related marketing infringed ACC trademark rights. Reuters reports that the complaint points to an ACC report that appeared in promotional material and seeks damages and injunctive relief. The L Suite had not responded to Reuters' request for comment when the report was published. These are allegations in a Delaware federal complaint, not findings that the materials were unlawfully copied, that the chatbot was improperly trained, or that any trademark was infringed.
Litigation AI GRC analysis
For in-house legal AI, the strongest governance issue is entitlement to source material. Before content moves into retrieval, fine-tuning, embedding, or automated legal workflows, the organization benefits from knowing what it owns, what it licenses, what contractual restrictions apply, and what attribution or usage terms follow the source. AI Agentic Automation Workflows Design can place those provenance checks upstream of tool orchestration: approved-source registries, matter and content permissions, human approval for high-impact actions, logging of external calls, and exception handling when a workflow encounters restricted material.
This case does not establish a legal rule for agentic systems. It illustrates why workflow automation and IP provenance need to be designed together, particularly for corporate legal departments and vendors building systems from professional content. The legal analysis remains claim- and contract-specific; the governance control is simply to make source authority visible before automation scales it.
X. Greenberg Traurig Faces SDNY Class Actions After Data Breach
Greenberg Traurig is facing putative class actions in the Southern District of New York after disclosing that an unauthorized actor accessed a limited number of documents and posted material on the dark web. Reuters reports that plaintiffs allege sensitive personal information was exposed and that the firm did not use adequate safeguards; the firm has said its core systems were not compromised and that only a small number of clients were affected. The complaints seek class treatment and relief, but the allegations have not been adjudicated. This is a cybersecurity and data-governance case, not an AI case, and the complaints do not allege that artificial intelligence caused the incident.
Litigation AI GRC analysis
Its relevance to an AI litigation briefing is architectural rather than causal. Legal AI programs can increase the number of places where matter data may move: external model providers, connectors, retrieval indexes, analytics systems, collaboration tools, and internal automation layers. New York Rule 1.6 and relevant professional guidance focus on reasonable confidentiality safeguards without making one technical architecture universally mandatory. For firms handling especially sensitive litigation, deal, IP, or investigation material, Air-Gapped Sovereign Sanctuary Vault In-House Platforms are one optional architecture for segregating selected workflows from public-cloud model access and preserving local audit trails. They are not a legal requirement and cannot be represented as a guarantee against cyber risk. The governance objective is narrower: match technical isolation, access control, logging, backup, incident response, and human operating procedures to the sensitivity of the matter and the firm's actual legal and contractual obligations.
Closing perspective
The strongest common thread this week is not 'more AI.' It is better evidence about AI-enabled work. Courts and counterparties may ask different legal questions, but the operational record repeatedly comes back to the same facts: what data entered the system, what source supported the output, what a human verified, which version was used, what exceptions occurred, and what was finally approved.That does not justify a universal AI ban, a universal disclosure rule, or a universal technical architecture. The defensible approach remains jurisdiction-specific and risk-based. New York Part 161, Ontario's quotation-certification amendments, the Federal Court's AI notice, U.S. evidence rules, professional-conduct duties, privacy and cybersecurity obligations, and voluntary governance standards operate in different legal categories. A reliable AI GRC program keeps those categories visible.For managing partners and legal departments, the practical test is simple: if a consequential AI-assisted workflow were challenged six months from now, could the organization produce a coherent evidence trail without guessing? If the answer is no, the issue is not merely AI adoption. It is governance design, litigation readiness, and information architecture.Educational Litigation AI GRC analysis only.
