The principle of Res Judicata prevents the same issue from being tried again in court by ensuring that once a matter has been finally decided by a competent court, the same parties cannot reopen the dispute on identical facts and issues. This doctrine acts as a legal bar against repetitive litigation, protecting both the judicial system and the litigants from unnecessary delay, expense, and conflicting judgments. It is considered vital for maintaining judicial efficiency because it upholds the finality of judgments, conserves court resources, and reinforces public confidence in the justice system by guaranteeing stability and consistency in legal decisions.
