Whether a federal court must consider the specific characteristics of an underlying state-court civil proceeding to determine whether it is sufficiently 'akin to a criminal prosecution' to warrant abstention under Younger v. Harris

QUESTION PRESENTED Whether, under Sprint Communications, Inc. v. Jacobs, 571 U.S. 69 (2018), a federal court must consider the specific characteristics of an underlying state-court civil proceeding to determine whether it is sufficiently “akin to a criminal prosecution” to warrant abstention under Younger v. Harris, 401 U.S. 37 (1971), as eight courts of appeals have held, or whether abstention is warranted whenever “the state proceeding falls within the general class” of state enforcement actions, App.7a, as the Ninth Circuit held in this case.
