In a surprise, the Supreme Court agreed this morning to hear cases arising out of the risk corridor mess. At issue is $12 billion in federal money, and the case’s outcome will hinge on what Congress meant when it placed limits on the use of appropriated funds in an effort to sabotage the Affordable Care Act.

I’m on the road, so a longer recap of the background and the litigation will have to wait. But I’ve been writing about the appropriations battle since 2014, and I thought I’d provide some resources if you’re interested in learning more about the case.

• I discuss the litigation at some length in this Pennsylvania Law Review piece laying out my view that

• And here’s my first piece from May 2014 on the whole fiasco—titled “Does the Risk Corridor Program Have a Fatal Technical Flaw?”
