Chief Justice John Roberts delivered the majority opinion, upholding most of the law. "The Framers created a Federal Government of limited powers, and assigned to this Court the duty of enforcing those limits. The Court does so today," he wrote. "But the Court does not express any opinion on the wisdom of the Affordable Care Act. Under the Constitution, that judgment is reserved to the people." (AP Photo/Michael Conroy)

In a concurring opinion, Associate Justice Ruth Bader Ginsburg sided with the majority in the ruling. Ginsburg is commonly associated with the liberal faction of the court. She said she agreed with much of Roberts' ruling, noting that she believes the law to be valid under the Constitution's Commerce Clause and Spending Clause. (AP Photo/Pablo Martinez Monsivais)

Justice Antonin Scalia voted with the minority in the health care decision. In the dissenting opinion, he, along with Justices Kennedy, Thomas and Alito, wrote that "we would find the Act invalid in its entirety."

Justice Clarence Thomas decided with the minority in the court's decision, adding in a very short opinion that both Chief Justice Roberts, who wrote the majority opinion, and the four dissenters "correctly apply our precedents to conclude that the [health care act's] Individual Mandate is beyond the power granted to Congress under the Commerce Clause and the Necessary and Proper Clause."

Long in front of the Supreme Court Justices on Monday, March 26, as the court began three days of arguments on the health care law signed by President Barack Obama. Long was asked by the Court to deliver the argument that precedent shows a court can't hear the case until someone had actually paid a penalty under the new law for not purchasing health insurance, according to news reports.
