A motion for summary judgment is a legal request made to a court to rule that the other party has no viable case because there are no genuine disputes of material fact. This motion aims to resolve a case without the need for a full trial by demonstrating that the evidence overwhelmingly supports one side, thus allowing the court to decide the issue based on the law. This process is tightly connected to the pretrial phase, particularly in how it can streamline litigation and determine what issues must actually be resolved at trial.
