Article III of the Constitution established the Judicial Branch of the United States government. The members of this branch are the nine Justices of the Supreme Court. These justices are appointed by the president, and remain in the job for life unless they resign, retire, die, or are impeached by the House of Representatives and convicted by the Senate. The Supreme Court’s most important responsibility is to decide cases that raise questions of constitutional interpretation, or whether or not someone has violated the Constitution. This is known as “judicial review”. Their decisions can only be changed by a constitutional amendment.
