Supreme Court upheld Obamacare by a 5-4 decision

The Supreme Court, in a landmark ruling, upheld President Obama's health care reform, including the controversial requirement that all Americans have health insurance. The court's judgment will allow the law to go forward with its aim of covering more than 30 million uninsured Americans.

The court, however, found problems with the law's expansion of Medicaid, but even there said the expansion could proceed as long as the federal government does not threaten to withhold states' entire Medicaid allotment if they don't take part in the law's extension.

The court's four liberal justices, Stephen Breyer, Ruth Bader Ginsburg, Elena Kagan and Sonia Sotomayor, joined Roberts in the outcome. Justices Samuel Alito, Anthony Kennedy, Antonin Scalia and Clarence Thomas dissented.
