Supreme Court of the United States · Official docket →

T. M. v. University of Maryland Medical System Corporation, et al.

Paid petition · United States Court of Appeals for the Fourth Circuit, No. 24-1707 · judgment June 4, 2025


Decided · June 18, 2026
Pre-decision estimate: 5% cert probability (95% interval 3%–8%)

Before the decision, modestly above the 4.1% base rate. The model weighted this up for counsel who has won certiorari before, a petition filed soon after the judgment below, and a Fourth Circuit decision below, and down for a business respondent.

Question presented

Whether the Rooker-Feldman doctrine can be triggered by a state-court decision that remains subject to further review in state court.
