True.
Your statement accurately describes several aspects of the U.S. judicial system:
- Judicial activism refers to judges interpreting laws broadly and often making decisions that expand judicial power.
- Judicial review, established in Marbury v. Madison, allows the Supreme Court to declare acts of Congress unconstitutional.
- The Senate does indeed nominate federal judges, with the President appointing them.
- The Supreme Court has both original and appellate jurisdiction.
- Federal courts handle cases involving federal law or disputes between citizens of different states.
All elements mentioned in your statement are correct.
