Answer:
Judicial review gives the Supreme Court the power to determine if a law passed by Congress or an act of the executive is unconstitutional.
Step-by-step explanation:
The Judicial Review power of the U.S. Supreme Court was established in 1803 by the landmark decision of Marbury v. Madison, and it refers to the Supreme Court's ability to review laws passed by Congress and check actions of the Executive branch to determine their unconstitutionality. This power is part of the system of Checks and Balances under which all three branches of the U.S. government rule.
