What does Rule 11 primarily aim to prevent in legal proceedings?

Rule 11 of the Federal Rules of Civil Procedure primarily aims to prevent the filing of cases that are deemed frivolous. This rule requires that attorneys or parties submitting documents to the court ensure that their filings are grounded in fact and law, and not intended to harass or cause unnecessary delay. By holding attorneys accountable for the claims they assert, Rule 11 seeks to deter unwarranted lawsuits that lack a legitimate basis, thus preserving judicial resources and ensuring that the courts are primarily occupied with cases that present substantive legal issues. This serves to maintain the integrity of the legal process, ensuring that the judicial system is not misused for purposes that do not contribute to the pursuit of justice.
