Rule 60(b) is a provision in the Federal Rules of Civil Procedure that allows a party to seek relief from a final judgment, order, or proceeding under specific circumstances. This rule enables individuals to request that the court set aside or modify a judgment due to reasons such as mistake, newly discovered evidence, fraud, or other compelling reasons. The purpose of Rule 60(b) is to ensure that justice is served and that parties are not unduly bound by decisions that may be fundamentally flawed.
