An Associate Justice is a member of the highest court in a jurisdiction, such as the Supreme Court in the United States. They work alongside the Chief Justice and other justices to interpret laws, hear cases, and make decisions that can impact the legal landscape of the country. Each justice is appointed by the President and confirmed by the Senate. Associate Justices serve lifetime appointments, which allows them to make decisions free from political pressures. Their role is crucial in upholding the Constitution and ensuring justice is served. They often write opinions that explain the court's rulings, contributing to legal precedents.
