1. “Given the ‘cardinal rule’ disfavoring implied repeals—which applies with ‘especial force’ to appropriations acts and requires that repeal not be found unless the later enactment is ‘irreconcilable’ with the former—can an appropriations rider whose text bars the agency’s use of certain funds to pay a statutory obligation, but does not repeal or amend the statutory obligation, and is thus not inconsistent with it, nonetheless be held to impliedly repeal the obligation by elevating the perceived ‘intent’ of the rider (drawn from unilluminating legislative history) above its text, and the text of the underlying statute?” 2. “Where the federal government has an unambiguous statutory payment obligation, under a program involving reciprocal commitments by the government and a private company participating in the program, does the presumption against retroactivity apply to the interpretation of an appropriations rider that is claimed to have impliedly repealed the government’s obligation?”
“These cases present three questions: First, did §1342 of the Affordable Care Act obligate the Government to pay participating insurers the full amount calculated by that statute? Second, did the obligation survive Congress’ appropriations riders? And third, may petitioners sue the Government under the Tucker Act to recover on that obligation? Because our answer to each is yes, we reverse.”
