Graham v. Connor objective reasonableness standard and qualified immunity.
North Dakota courts apply both the U.S. Constitution and the North Dakota Constitution to excessive force claims. When state protections are broader than federal ones, North Dakota judges follow the state rule. When they are equal or narrower, federal precedent controls under the Supremacy Clause.
Federal cases governing excessive force include controlling U.S. Supreme Court decisions and binding precedent from the federal circuit covering North Dakota. Civil remedies most often proceed under 42 U.S.C. § 1983, with defenses including qualified immunity.
