Imagine your school principal creates a new rule banning all backpacks, but the school district charter says every student has the right to carry their books safely.

Who decides which rule wins: the principal's new policy or the supreme school charter?

In the United States government, **judicial review** is the power of the courts to examine laws and government actions to decide if they violate the U.S. Constitution.

If the Supreme Court finds that a federal or state law clashes with the Constitution, that law is declared **unconstitutional** and immediately becomes void.

Where does this immense power come from if the words 'judicial review' never actually appear in the Constitution?

In 1803, Chief Justice John Marshall established judicial review in the landmark case ***Marbury v. Madison*** when deciding whether William Marbury should receive an official judge commission.

Marshall reasoned that because the Constitution is the 'supreme Law of the Land' (Article VI), any ordinary act of Congress that conflicts with it cannot stand.

How does this power fit alongside the President and Congress in our three-branch system?

Judicial review serves as the judicial branch's primary tool in the system of **checks and balances**, ensuring neither Congress nor the President exceeds their constitutional limits.

A common misconception is thinking the Supreme Court searches through every new law to approve or reject it right away.

In reality, the Court can only exercise judicial review when someone brings an actual legal dispute or lawsuit (a 'case or controversy') before them.

As you explore upcoming landmark cases, watch for how the Court uses this referee whistle to reshape American society.

Landmark Case Study & Video: Marbury v. Madison and Judicial Review

Judicial Branch in a Flash & Marbury v. Madison Lesson Curriculum

When teaching TEKS 8.18(A) to 8th graders, center the narrative on the high-stakes political drama of 1801–1803 (Adams's 'midnight judges' vs. Jefferson/Madison) so students understand the practical origin of the doctrine before abstracting it into constitutional theory. Use visual hierarchy models (Constitution at the apex, ordinary statutes below) and guided primary source excerpts (focusing on Marshall's core argument in Marbury v. Madison) to solidify comprehension of checks and balances.
