Non-Merits Matters at the Supreme Court



February 2, 2026

Over the past decade, the U.S. Supreme Court has issued approximately fifty to eighty decisions per year
in merits cases-matters that receive full briefing and oral argument-as well as thousands of orders
disposing of non-merits matters. The Court's non-merits matters, or subsets of its non-merits matters, are
known  by various names, including the emergency docket, the shadow docket, and the interim docket.
The non-merits docket encompasses a variety of matters-ranging from petitions for writs of certiorari to
routine procedural motions to requests for emergency relief-that can have immediate and far-reaching
practical impacts.
