Prompt Title: Rule 11 federal court.

Rule 11 of the Federal Rules of Civil Procedure is a rule that governs the signing and filing of pleadings, motions, and other papers in federal court. The purpose of Rule 11 is to promote the truthful and non-frivolous presentation of legal arguments and to discourage the filing of baseless or unsupported claims or defenses.

Under Rule 11, every pleading, motion, or other paper filed with the court must be signed by the attorney or party who files it. By signing the document, the signer is certifying that to the best of their knowledge, information, and belief, formed after an inquiry reasonable under the circumstances:

1. the document is not being presented for any improper purpose, such as to harass, cause unnecessary delay, or needlessly increase the cost of litigation;

2. the claims, defenses, and other legal contentions are warranted by existing law or by a nonfrivolous argument for extending, modifying, or reversing existing law or for establishing new law;

3. the factual contentions have evidentiary support or, if specifically so identified, will likely have evidentiary support after a reasonable opportunity for further investigation or discovery; and

4. the denials of factual contentions are warranted on the evidence or, if specifically so identified, are reasonably based on belief or a lack of information.

If a party or attorney violates Rule 11, the court may impose sanctions, which can include monetary sanctions, dismissal of the action, or other appropriate action.
