The nine Supreme Court Justices on the Supreme Court of the United States are the final arbiters on whether or not a law passed by the legislative branch is constitutional.
The Supreme Court Justices. The Supreme Court is the highest court in the land. It has a chief justice, or head judge, and eight associate justices. The justices are appointed by the president and approved by a vote of the Senate. The justices serve for life unless they choose to retire. Their job is to interpret laws passed by Congress. Since our government was established, more than one hundred justices have served on the Court, and until recently, all were men. Sandra Day OâConnor was the first woman named to the Supreme Court. She was appointed in 1981.
