Robert H. Jackson, American politician, 57th United States Attorney General, Nuremberg prosecutor, and Supreme Court justice (died 1954)

Robert Houghwout Jackson was an American lawyer, jurist, and politician who served as an associate justice of the U.S. Supreme Court from 1941 until his death in 1954. He had previously served as United States Solicitor General and United States Attorney General, and is the only person to have held all three of those offices. Jackson was also notable for his work at the Nuremberg trials prosecuting Nazi war criminals following World War II. Jackson developed a reputation as one of the best writers on the Supreme Court and one of the most committed to enforcing due process as protection from overreaching federal agencies.

The United States attorney general is the head of the United States Department of Justice and serves as the chief law enforcement officer of the federal government. The attorney general acts as the principal legal advisor to the president of the United States on all legal matters. The attorney general is also a statutory member of the Cabinet of the United States and a member of the United States National Security Council. Additionally, the attorney general is seventh in the presidential line of succession.

The Nuremberg trials were held by the Allies against representatives of the defeated Nazi Germany for plotting and carrying out invasions of other countries across Europe and committing atrocities against their citizens in World War II.

In most legal jurisdictions, a supreme court, also known as a court of last resort, apex court, high court of appeal, and court of final appeal, is the highest court within the hierarchy of courts. Broadly speaking, the decisions of a supreme court are binding on all other courts in a nation and are not subject to further review by any other court. Supreme courts typically function primarily as appellate courts, hearing appeals from decisions of lower trial courts, or from intermediate-level appellate courts. A supreme court can also, in certain circumstances, act as a court of original jurisdiction.
