What the order requires

Judge John P. Cronan’s Individual Civil Rules § 2.E (updated October 23, 2025) requires a detailed verification certification with any AI-assisted filing. Unlike many disclose-and-certify orders, Cronan’s certification is procedurally rigorous: it must (i) state whether the litigant personally reviewed the filing for accuracy and (ii) describe in detail the verification steps taken for all AI-generated content.

The “describe in detail” requirement raises the practical bar above a check-the-box certification. Firms should expect to document the specific verification steps taken (e.g., “each cited case was confirmed by retrieving the Westlaw print of the opinion and reading the cited proposition”) rather than reciting boilerplate.
