Claim Preclusion is a legal doctrine that prevents a party from re-litigating a claim that has already been decided by a competent court. Once a final judgment is made in a case, the same parties cannot bring the same issue back to court. This helps ensure that legal disputes are resolved efficiently and prevents the same matter from being tried multiple times. The purpose of Claim Preclusion is to promote finality and consistency in the legal system. It protects the integrity of court decisions and saves judicial resources by discouraging repetitive lawsuits. This principle applies to both civil and criminal cases, reinforcing the idea that legal matters should be settled definitively.
