WASHINGTON - The U.S. Supreme Court on March 26 showed clear signs that it is ready to tackle the contentious issue of the constitutionality of the Affordable Care Act sooner rather than later.

On the first of three days of historic oral arguments on the health care law, the justices considered what could have been a show-stopping issue: whether the Court has jurisdiction to consider the issue now at all, or whether it has to wait until 2015, when the first taxpayer who refuses to buy health insurance under the so-called “individual mandate” is required to pay a penalty to the IRS.
