Final answer:
The judge who oversaw the case of Marbury v. Madison was Chief Justice John Marshall. The case established the principle of judicial review and strengthened the power of the Supreme Court.
Step-by-step explanation:
The judge who oversaw the case of Marbury v. Madison was Chief Justice John Marshall.
In 1803, Chief Justice John Marshall ruled on the case of Marbury v. Madison, which established the principle of judicial review. Marshall agreed that William Marbury had the right to a legal remedy but found that the Judicial Act of 1789, which would have given the Supreme Court the power to grant Marbury remedy, was unconstitutional.
This ruling strengthened the court by asserting its power to review and possibly nullify the actions of Congress and the president.
