Given the growing concern even among Democrats that ObamaCare will result in a “huge train wreck” later this year, I have a few questions for Health and Human Services Secretary Kathleen Sebelius to add to my previous list:

1. What happens if a federal court (say, the Eastern District of Oklahoma) issues an injunction barring HHS from making “advance payments of tax credits” in the 33 states with federal Exchanges?
2. Has HHS done any planning for that contingency? If so, what are those contingency plans?
3. If HHS has not, why not? Given that the Congressional Research Service and Harvard Law Review both say there’s a credible case that the PPACA forbids tax credits in the 33 states with federal Exchanges, how could HHS not have a contingency plan ready?

For more on how HHS is violating federal law by planning to issue advance payments of tax credits through federal Exchanges, read my Cato white paper, “50 Vetoes: How States Can Stop the Obama Health Care Law,” and my Health Matrix article (with Jonathan Adler), “Taxation Without Representation: The Illegal IRS Rule to Expand Tax Credits Under the PPACA.”
