The court also upheld the individual mandate provision of the law, which would require most US citizens to obtain health insurance by 2014, or pay a monetary penalty, Wikinews reported.
Chief Justice John Roberts and Justices Stephen Breyer, Ruth Bader Ginsburg, Elena Kagan and Sonia Sotomayor were in the majority, while Samuel Alito, Anthony Kennedy, Antonin Scalia and Clarence Thomas were in the minority in supporting the repeal of the law.
The Court did, however, strike down a provision of the law which would have expanded Medicaid to make coverage available to anyone with an income less than 138% of the federal poverty line.
In the ruling John Roberts wrote, “Simply put, Congress may tax and spend. The federal government may enact a tax on an activity that it cannot authorize, forbid or otherwise control.”
The ruling on the law comes after 26 states challenged the law in oral arguments in front of the Supreme Court in March.
