Washington (CNN) — As expected, the Supreme Court has agreed to decide the constitutionality of the sweeping health care reform law championed by President Barack Obama.The justices made their announcement in a brief order issued Monday.Oral arguments are likely to be held in late February or March, with a ruling by June, assuring the blockbuster issue will become a hot-button political debate in a presidential election year.The high court agreed to hear two major questions: whether the law’s key provision is unconstitutional, and if so, whether the entire law, with its 450 sections, must be scrapped.
