Washington, DC (WIBX) - It is the third and final day of oral arguments on the Patient Protection and Affordable Care Act, broadly referred to as "the healthcare reform law," in the United States Supreme Court.

The central issue on everyone's mind this morning is whether the rest of the law can stand up if one of its main tenets is ruled unconstitutional.

What is often cited as the most controversial individual mandate is the one that requires most American citizens to purchase healthcare insurance or face a fine.

Fervent arguments have been heard on both sides of the case both in front of the Court and outside of its walls.
