A federal Pennsylvania judge ruled the new health care law's mandate that individuals buy health insurance is unconstitutional.
Judge Christopher C. Conner said Tuesday the government shouldn't have the power to dictate buying insurance.
"The nation undoubtedly faces a health care crisis," Conner said. "Scores of individuals are uninsured and the costs to all citizens are measurable and significant."
"The federal government, however, is one of limited enumerated powers, and Congress's efforts to remedy the ailing health care and health insurance markets must fit squarely within the boundaries of those powers," he added.
This case is just one of more than 30 lawsuits against the Obama administration's health care overhaul.
Last week, the 4th U.S. Circuit Court of Appeals in Virginia struck down another case challenging the law. The court ruled the commonwealth didn't have legal standing to file its lawsuit.
Many expect the issue will ultimately be settled by the U.S. Supreme Court.
