2) Summary of the Opinion
The Affordable Care Act (ACA) required most Americans to purchase health insurance or pay a penalty. Opponents argued it exceeded Congress’s power under the Commerce Clause. The Supreme Court ruled that the mandate was unconstitutional under the Commerce Clause but upheld it as a valid exercise of Congress’s taxing power. The Court also struck down the mandatory expansion of Medicaid as coercive, making it optional for states.
