In force when read In force since 23 June 2026; read on 5 November 2026.

  • No certificate of its own

The court’s words

“(b) Due to the risk that generative AI can create inaccurate factual and legal information, including, without limitation, faulty citations to legal authority, fabricated quotations from such authority, and inaccurate or fabricated evidence, any person who uses generative AI in the creation or editing of any document filed with the court shall independently verify all citations, legal authorities or evidence produced by generative AI. The failure to do so may result in court-imposed sanctions, including, without limitation, the entry of a nonsuit or default judgment. (c) Any person who files documents with the court represents that they have reviewed this rule and, by filing the document, represents that they have made good faith, diligent efforts to ensure compliance with their obligations under this rule, all other rules of practice, the Rules of Professional Conduct, and any applicable provision of Connecticut law regarding the use of or reliance on generative AI.”

What it asks of the person who signs

  • No certificate of its own

    the duty to verify every citation, restated; the signature carries it.

Applies to: Any document filed with the court in whose creation or editing generative AI was used. Where it goes: Made by filing: under § 4-9 (c), filing the document is the representation that the rule was followed. No separate statement.

The statement, if one is called for

Nothing to draft: under this rule, filing the paper is itself the statement.

On the check page Loupe drafts the statement for this court from the parts you tick, for you to read and sign: what it says is your choice and your responsibility. The order in force on the day is what counts; read it at the source before relying on this page.

Check the filing first

Paste the brief or drop the file, and Loupe looks up every citation in the published record: whether the case exists, whether it is the case the filing names, whether the pin cite falls inside the opinion; statutes, regulations, court rules and links too. It doesn’t generate anything, and what it can’t settle it marks “not verified”, never clean.
