Justices are judges who serve on a court, making decisions on legal cases. They interpret laws and ensure justice is served according to the legal system. In many countries, justices are appointed or elected to their positions and may serve for a specific term or for life, depending on the jurisdiction. In the United States, the highest court is the Supreme Court, which consists of nine justices. These justices review cases that involve important legal questions and can influence laws and policies. Their rulings can have a significant impact on society and the interpretation of the Constitution.
