Offensive use refers to the strategy where a party, typically a plaintiff, utilizes issue preclusion to bar a defendant from relitigating an issue that has already been decided in a prior case. This application is particularly significant as it allows parties to leverage previous judgments to strengthen their current claims, making it a powerful tool in litigation. By asserting that an issue has been conclusively determined, the party can prevent the opposing side from arguing that issue again, thus streamlining the judicial process and reducing unnecessary duplicative litigation.
