A supreme court is the highest judicial authority in a country or state, responsible for interpreting laws and ensuring justice. It typically has the final say on legal disputes and constitutional matters, making its decisions binding on lower courts. Supreme courts often review cases that involve significant legal questions or conflicts between different laws. In many countries, supreme courts are composed of appointed or elected judges who serve for a specific term or until retirement. They play a crucial role in upholding the rule of law and protecting individual rights, often addressing issues related to civil liberties, government powers, and social justice.
