Standing is a legal concept that determines whether a party has the right to bring a lawsuit in court, based on their stake or interest in the outcome of the case. It ensures that only those who have suffered a direct injury or have a legitimate interest can seek legal remedy, preventing courts from being burdened with cases brought by individuals who are not personally affected. This principle is crucial for maintaining the integrity of the judicial system and ensures that disputes are resolved by parties with a genuine connection to the matter.
