Understanding Judicial Review

The power of the Supreme Court to declare a law unconstitutional is known as judicial review. This fundamental principle of American law allows the Court to examine legislative acts and executive actions to determine if they comply with the U.S. Constitution. If a law is found to violate constitutional principles, the Court can strike it down, rendering it unenforceable. This authority ensures that all government actions remain within the bounds established by the Constitution.

Recent Instances of Laws Declared Unconstitutional

The Supreme Court regularly reviews laws and government actions for their constitutionality. Based on recent records, here are the most recent instances where the Court declared a law unconstitutional, in whole or in part:

As evident from this list, the ruling in United States v. Washington on June 21, 2022, marks the most recent occasion the Supreme Court exercised its power of judicial review to strike down a law.

Impact of a Ruling of Unconstitutionality

When the Supreme Court declares a law unconstitutional, the implications are significant:

• Invalidation of the Law: The specific provision or the entire law is rendered void and cannot be enforced.
• Precedent Setting: The decision establishes a legal precedent that lower courts must follow in similar cases.
• Checks and Balances: It reinforces the system of checks and balances, ensuring that no single branch of government oversteps its constitutional authority.
• Legislative Response: Congress may need to revise or repeal the invalidated law, or pass new legislation that complies with the Court's ruling.

These decisions are pivotal in shaping American law and upholding the constitutional framework of the United States.
