Logging duty
Article 371 requires an attorney to disclose to the court when evidence was, or should have been, known to be false or artificially generated, but it does not require the attorney, a party, or any technology provider to keep a log, record, or file documenting how the evidence was verified. The duty is a disclosure to the court in the moment, not a record-keeping duty.

What this law does
Drafted with AI from the cited sources under the direction of UnGovr staff. UnGovr holds editorial responsibility for this page.
As part of a broad, Louisiana State Law Institute-recommended revision of the Code of Civil Procedure, Article 371 was amended to add that an attorney shall not knowingly encourage or produce false evidence, including evidence that is artificially generated or altered by any means, and shall exercise reasonable diligence to verify the authenticity of evidence before offering it to a court.
Offering evidence that the attorney knew or should have known through reasonable diligence was false or artificially manipulated, without disclosing that fact, is a violation of the Article, subjecting the attorney to punishment for contempt of court and other professional discipline. Signed by Governor Landry on June 11, 2025 as Act 250 (House Bill 178) and in effect since August 1, 2025.
