(FOX NEWS) On the final day of arguments over President Obama’s health care law, Supreme Court justices struggled Wednesday over what to do with the rest of the Affordable Care Act if they also rule that its central provision is invalid.

The question dealt with whether the entire health care law should stay or go or be revised if the so-called individual mandate — the requirement that everyone buy health insurance — is struck down. That, and a debate over the law’s Medicaid requirements, marked the final arguments in the landmark case, as court adjourned in mid-afternoon.

The mandate discussion centered on what to do now with this case but also on concerns over the proper role for the courts in interpreting what Congress would want done with a law that’s been changed from its original version.
