In Trigalet v. City of Tulsa, Oklahoma, 239 F.3d 1150 (10th Cir. 2001), the Court of Appeals held, consistent with nearly every other Court of Appeals, that a municipality cannot be held liable in a 42 U.S.C. section 1983 action in the absence of a predicate unconstitutional act by the municipality's employee. Even if the municipality's actions are arbitrary or even "conscience shocking, in a constitutional sense" the municipality cannot be held liable under Section 1983. Id. at 1151. This is because a claim of "inadequate training [or] supervision . . . under 1983 cannot be made out against a supervisory authority absent a finding of a constitutional violation by the person supervised." Id. at 1154 (quoting Webber v. Mefford, 43 F.3d 1340, 1344-45 (10th Cir. 1994)).
