Answer:
A motion for summary judgment asks the judge to dismiss the claims before the court. A moving party asks the court to assume that all of the allegations made by the plaintiff are true and even if all true asks the court to rule that no valid claim has been made by the plaintiff. For example, suppose the plaintiff sues the defendant for wearing a red tie. The defendant would admit that he wore a red tie, and ask the court to make a ruling that there is no possible recovery for the plaintiff when he defendant wears a red tie.
