The U.S. Supreme Court said today that it will hear the challenge to President Obama’s 2010 health care overhaul law. Although the high court was expected to review the case, the latest news offers a timeline of how the court’s handling of the challenge will play out—with oral arguments set to begin in March 2012 and a decision by late June.

The 2010 law has seen its fair share of time in court. More than 25 cases have challenged the health care overhaul, and the battle made its way to three circuit courts. While the 4th and 6th Circuits upheld the law, the 11th Circuit said that Congress exceeded its power to regulate commerce when it said people must buy health insurance or pay a penalty.

The Justices said today, as a result of the Circuit split, that they will decide the constitutionality of the Patient Protection and Affordable Care Act. The Obama administration is confident it will prevail.

“We know the Affordable Care Act is constitutional and are confident the Supreme Court will agree,” said Dan Pfeiffer, the White House communications director, in a statement today.
