One thing I learned as a Constitutional Law prof many years ago is to not give full faith and credit to the comments and questions of Justices during oral argument. Sometimes they are simply testing out ideas that they plan to write against when the dust settles. All that said . . .
Early reports from today's oral argument in the Supreme Court suggest that Justices Sotomayor, Kagan, and Breyer may be joined by Chief Justice Roberts and Justice Kavanaugh in upholding the ACA against the attack mounted by 20 GOP-led states. Policy wonks decry the possibility that 20 million people in this country could lose their health insurance if the ACA is struck down, and millions more will lose coverage if other underwriting reforms go down the tubes, including the prohibition against discriminating on the basis of pre-existing conditions, the ban on annual and lifetime caps, and the option for children to be covered by their parents' health insurance until they turn 26. The Supreme Court doesn't get to make health policy, but consequences as Draconian as these have to figure into their reading of the law, especially in a case in which congressional intent controls the issues.
There are two issues in play. The first is whether the individual mandate can survive Congress's decision in the 2017 tax law to reduce the penalty tax for failing to secure health insurance all the way down to $0. Without a tax, the plaintiffs have argued, the constitutional basis for the mandate disappears. Maybe. I seem to remember from Income Tax I (Summer 1975) that Congress has from time to time elected not to collect a tax, and the Court has upheld the regulation attached to the tax nonetheless. Even if I recollect incorrectly, it should be at least a close question whether Congress intended to wipe out the individual mandate when they reduced the tax. It seems supremely silly to me
If the Court answers the first question in the affirmative, the second question shouldn't be close at all: whether the end of the individual mandate means the entire ACA should be tossed out as well. The question is one of severability, and it shouldn't even pass the smile test, although the district court and the Fifth Circuit opined that the ACA could not be saved if the individual mandate were taken out.
Stay tuned . . .
