Obama administration lawyers face a decision by Monday that carries a high political risk and will probably determine whether the Supreme Court decides on the constitutionality of the healthcare law before next year's presidential election. The Justice Department could ask the full U.S. 11th Circuit Court of Appeals in Atlanta to reconsider a 2-1 decision in August that declared the law's mandate that all Americans must have health insurance unconstitutional. But seeking the full court review could take weeks, or even months, and probably push back a Supreme Court ruling until 2013. Or government lawyers could opt to skip the full review in the lower court and appeal directly to the Supreme Court this fall.
