The principle of Res Judicata is considered crucial in civil cases because it upholds the finality of judgments and ensures that once a dispute has been conclusively resolved, the same issue cannot be re-litigated between the same parties. This prevents courts from being overburdened with repetitive cases, saving valuable time and resources. By discouraging multiple lawsuits over the same matter, it also protects individuals from unnecessary harassment and expenses. In essence, Res Judicata promotes judicial discipline, consistency, and certainty, while strengthening public trust in the legal system by ensuring that disputes, once settled, remain settled.
