Unlawful stops, searches, and seizures under the Fourth Amendment.
Louisiana courts apply both the U.S. Constitution and the Louisiana Constitution to fourth amendment search & seizure claims. When state protections are broader than federal ones, Louisiana judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing fourth amendment search & seizure include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering Louisiana. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
