What vote did the Supreme Court use to uphold the individual mandate in 2012?

In 2012, the Supreme Court upheld the individual mandate of the Patient Protection and Affordable Care Act by a 5–4 vote.1

Chief Justice John Roberts wrote the majority opinion, which was joined by Justices Ruth Bader Ginsburg, Sonia Sotomayor, Stephen Breyer, and Elena Kagan. While Roberts rejected the government's argument that the mandate was a valid exercise of Congressional power under the commerce clause, he concluded that the mandate was constitutional as a tax under Congress’s taxing and spending powers.12
