Wyo. Stat. § 1-39-102

(a) The Wyoming legislature recognizes the inherently unfair and inequitable results which occur in the strict application of the doctrine of governmental immunity and is cognizant of the Wyoming Supreme Court decision of Oroz v. Board of County Commissioners 575 P.2d 1155 (1978) . It is further recognized that the state and its political subdivisions as trustees of public revenues are constituted to serve the inhabitants of the state of Wyoming and furnish certain services not available through private parties and, in the case of the state, state revenues may only be expended upon legislative appropriation. This act is adopted by the legislature to balance the respective equities between persons injured by governmental actions and the taxpayers of the state of Wyoming whose revenues are utilized by governmental entities on behalf of those taxpayers. This act is intended to retain any common law defenses which a defendant may have by virtue of decisions from this or other jurisdictions.

(b) In the case of the state, this act abolishes all judicially created categories such as “governmental” or “proprietary” functions and “discretionary” or “ministerial” acts previously used by the courts to determine immunity or liability. This act does not impose nor allow the imposition of strict liability for acts of governmental entities or public employees.
