Circuit precedent and clearly established law

We're live at WashU Law's Admitted Students Day! After catching up on some shadow docket activity, we dig into Olivier v. City of Brandon, the Court's unanimous March 2026 decision by Justice Kagan. A Mississippi street preacher pleads no-contest to violating an amphitheater protest-zone ordinance, pays his $304 fine, then sues under §1983 to stop future enforcement — and the Fifth Circuit says the puzzling Heck v. Humphrey rule bars the whole thing. We work through why Heck is stranger than it first appears, what the Court got right in resolving the circuit split, and what the decision reveals about the ongoing mess at the intersection of §1983 and habeas.
