The individual mandate that requires all Americans to buy health insurance or pay a fine was upheld as constitutional "as a tax". (The Urban Institute states that only about 6% of all Americans would be required to buy health insurance since the majority of Americans have coverage or get it through Medicare.)

Roberts delivered the majority opinion for Justices Ruth Bader Ginsburg, Stephen Breyer, Sonia Sotomayor and Elena Kagan. Justice Anthony Kennedy delivered the dissent opinion on behalf of Justices Antonin Scalia, Clarence Thomas and Samuel A. Alito Jr.
