Judge Glenn Suddaby

Judge Glenn Suddaby serves as a senior United States district judge in the Northern District of New York, appointed by President George W. Bush in 2008. Before the bench, he spent years as United States Attorney for the Northern District—the top federal prosecutor in the region. That prosecutorial background means he knows exactly what a properly prepared filing looks like, and he has zero tolerance for sloppy work.

New York's federal courts are navigating AI disclosure without a uniform rule. As of late 2025, there is no district-wide or state-wide local rule on disclosing AI use in court filings across New York's federal districts. Individual judges are issuing their own guidance, creating a patchwork of requirements that attorneys must navigate case by case. Judge Suddaby's engagement with AI issues—including a May 2026 CLE program on ethical AI use in brief preparation featuring his career law clerk—signals a judge who's actively thinking about these questions.

Judge Suddaby's Prosecutorial Background and Standards

Before joining the bench, Judge Suddaby served as United States Attorney for the Northern District of New York from 2002 to 2008, appointed by President George W. Bush. As the chief federal law enforcement officer in the district, he supervised prosecutions requiring meticulous factual accuracy and legal precision. That background shapes how he evaluates filings. Attorneys who submit AI-generated content without verification are presenting the kind of unvetted work product that a former US Attorney finds unacceptable. His uniform pretrial scheduling orders reflect detailed expectations for case preparation—expectations that extend to how attorneys draft their submissions.

The CLE Signal: AI Ethics in Brief Preparation

In May 2026, the Western District of New York hosted a Virtual CLE Program titled "How to Ethically Use—and Not Misuse—Gen-AI to Prepare a Legal Brief," featuring Michael G. Langan, Esq., career law clerk to Judge Suddaby. When a judge's own law clerk is presenting nationally on AI ethics in legal briefing, that tells you everything you need to know about the judge's awareness. Judge Suddaby isn't waiting for a formal rule—he's actively ensuring that the legal community understands the ethical boundaries of AI use. Attorneys filing before him should assume he's fully informed about AI capabilities, limitations, and risks.

New York's Federal AI Disclosure Landscape

New York's federal courts are a patchwork when it comes to AI rules. The Southern District has individual judges with varying approaches—some require disclosure, others don't. The Eastern District has judges developing their own individual practices. The Northern District, where Judge Suddaby sits, has no district-wide AI order. Instead, practitioners must check each judge's specific requirements. This creates a compliance challenge: an attorney practicing across New York's four federal districts might face different AI rules in each one. The only safe approach is to verify everything and disclose proactively, regardless of whether a specific judge requires it.

Gun Rights and High-Profile Constitutional Cases

Judge Suddaby has handled significant constitutional cases, including Second Amendment challenges that draw national attention. High-profile constitutional litigation attracts amicus briefs, media scrutiny, and appellate review—all of which increase the consequences of AI-related errors. In cases where the outcome shapes national policy, submitting a brief with fabricated case law doesn't just earn sanctions—it undermines the constitutional arguments themselves. Attorneys involved in consequential cases before Judge Suddaby should apply the highest standard of verification to every element of their filings.

Best Practices for Filing Before Judge Suddaby

Step 1: Review Judge Suddaby's uniform pretrial scheduling order and any case-specific requirements on the Northern District's website. Step 2: Verify every AI-assisted citation through Westlaw or Lexis—his prosecutorial background means he'll catch errors that other judges might miss. Step 3: Follow the ethical framework presented in the CLE program his law clerk delivered—it represents the standards his chambers applies. Step 4: Disclose AI use voluntarily, as New York's federal courts are trending toward mandatory disclosure. Step 5: Prepare as if your filing will face appellate-level scrutiny—Judge Suddaby's constitutional cases often end up before the Second Circuit.

The Bottom Line: Judge Suddaby brings a federal prosecutor's standards to the bench and is actively engaged with AI ethics through his chambers. New York has no uniform AI disclosure rule, but his law clerk's national CLE presentation on AI ethics in briefing tells you where his courtroom stands. Verify everything and treat AI disclosure as expected practice.
