Understanding Offensive Collateral Estoppel: Key Legal Insights

Definition & Meaning

Offensive collateral estoppel is a legal doctrine that prevents a defendant from re-litigating an issue that has already been decided against them in a previous case. This means that if an issue has been conclusively determined in one lawsuit, the defendant cannot later challenge that same issue in a different lawsuit. For instance, if person A successfully sues person B over a property boundary dispute, person B cannot later file a lawsuit claiming that the property line is incorrect.
