Today’s arguments before the U.S. Supreme Court on the fate of President Obama’s Affordable Care Act, the second of three days of hearings on the health care overhaul, mainly tackles the constitutionality of the individual insurance mandate. The requirement dictates almost all Americans buy health insurance in 2014 or pay a penalty when they file their 2014 income taxes in early 2015.

Justices on Wednesday will hear debates on whether the rest of the law can take effect even if the individual insurance mandate is unconstitutional, and also arguments over expansion of the Medicaid program for lower-income people.

Did Congress overstep its authority by requiring Americans to obtain health insurance starting in 2014 or face a penalty? Can the healthcare law work without the individual mandate?
