Justices are judges who serve on a court, often at the highest level, such as the Supreme Court in a country. Their primary role is to interpret laws, ensure justice, and protect the rights of individuals. Justices make decisions on legal cases, which can set important precedents for future cases. In many legal systems, justices are appointed or elected and serve for a specific term or for life. They review cases that have significant legal implications, and their rulings can influence legislation and public policy. The work of justices is crucial for maintaining the rule of law and upholding the constitution.
