In Marbury v. Madison, who was the Chief Justice who wrote the decision establishing judicial review?

• A. John Marshall
• B. Roger B. Taney
• C. Earl Warren
• D. John Roberts

Answer: (A)

The idea being tested is who established judicial review—the power of the courts to strike down laws that conflict with the Constitution. In Marbury v. Madison, the ruling written by Chief Justice John Marshall declared that the Constitution is the supreme law and that it is the judiciary’s duty to interpret laws and review acts of Congress. This opinion cemented judicial review, giving the Supreme Court a final say in constitutional matters and strengthening the judiciary as a check on legislation. The other names were Chief Justices in later periods and did not author this decision: Roger B. Taney served after Marshall and is known for the Dred Scott case; Earl Warren led the Court in the mid-20th century; John Roberts is the current Chief Justice.
