The Supreme Court upheld the health care law today in a splintered, complex opinion that gives President Obama a major victory.
Basically. the justices said that the individual mandate -- the requirement that most Americans buy health insurance or pay a fine -- is constitutional as a tax.
Chief Justice John Roberts -- a conservative appointed by President George W. Bush -- provided the key vote to preserve the landmark health care law, which figures to be a major issue in Obama's re-election bid against Republican opponent Mitt Romney.
The government had argued that Congress had the authority to pass the individual mandate as part of its power to regulate interstate commerce; the court disagreed with that analysis, but preserved the mandate because the fine amounts to a tax that is within Congress' constitutional powers.
The announcement will have a major impact on the nation's health care system, the actions of both federal and state governments, and the course of the November presidential and congressional elections.
A key question for the high court: The law's individual mandate, the requirement that nearly all Americans buy health insurance, or pay a penalty.
Critics call the requirement an unconstitutional overreach by Congress and the Obama administration; supporters say it is necessary to finance the health care plan, and well within the government's powers under the Commerce Clause of the U.S. Constitution.
