Why it matters

Connecticut's Appellate and Supreme Courts have imposed mandatory verification requirements for all AI-generated citations, legal authorities, and evidence effective June 23, 2026. The rules threaten case-ending sanctions—including nonsuit or default judgment—for violations. The directive emerged from enforcement action against GLG Law LLC and a landlord's attorney whose filings contained ChatGPT-induced errors, including fabricated quotations and faulty citations. The Connecticut Judicial Branch and its AI Committee developed the policy, which now applies to all attorneys and pro se litigants in state courts.

The Supreme Court is actively considering sanctions against the GLG Law attorney, making this an immediate enforcement test. The CT Bar Association's Generative AI Committee is studying the issue separately but has not yet issued guidance. Details of the specific sanctions framework remain under development as the court weighs penalties in the pending case.

This rule formalizes a standard first signaled in a 2025 federal notice from the U.S. District of Connecticut, which warned that unverified AI content triggers Rule 11 sanctions. Connecticut's state-level mandate shifts enforcement from voluntary ethics guidance to mandatory verification with severe penalties. Attorneys should expect that other jurisdictions will adopt similar standards, making independent verification of all AI-generated content a baseline professional obligation rather than a best practice.
