Probable cause, false arrest, and civil rights remedies under 42 U.S.C. § 1983.
Connecticut courts apply both the U.S. Constitution and the Connecticut Constitution to unlawful arrest claims. When state protections are broader than federal ones, Connecticut judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing unlawful arrest include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering Connecticut. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
