The Fifth Circuit is the latest court to address potential misuse of generative artificial intelligence. The court is seeking comments on an amendment to Rule 32.3 that would require litigants to certify that they reviewed and verified any GenAI-generated content in their filings. Failure to comply could result in striking the document or sanctions. The Fifth Circuit is the first federal appeals court to consider a GenAI-specific rule. But its proposal comes on the heels of a flurry of lower court standing orders aimed at addressing similar concerns. These issues make it essential for lawyers to stay informed about developments in GenAI technology and ensure they are complying with applicable court rules. Indeed, the only thing that is certain in this area is that there will continue to be change.
