From the New York Times:

The Obama administration won the first appellate review of the 2010 health care law on Wednesday as a three-judge panel from the United States Court of Appeals for the Sixth Circuit in Cincinnati held that it was constitutional for Congress to require that Americans obtain health insurance.

Scotusblog has analysis:

The key feature of Congress’s broad new health care law ““ a mandate that virtually every one obtain health insurance by the year 2014 ““ on Wednesday survived its first constitutional challenge in a federal appeals court, but it did so with little room to spare. Three judges on the Sixth Circuit Court in Cincinnati took three different positions, but the one that counted the most rejected only the broadest challenge, and suggested that narrower ones might have some success as the law is actually put into effect.
