Wyo. Stat. § 9-13-106

(a) A public official, public member or public employee shall not make an official decision or vote on an official decision if the public official, public member or public employee has a personal or private interest in the matter. In determining whether he has a personal or private interest in a matter the public official shall recognize the importance of his right to represent his constituency and shall abstain from voting only in clear cases of a personal or private interest as defined in this subsection. A public official or public member shall not vote to give money or any direct financial benefit to himself except for tax reductions affecting the general public. For the purposes of this section, a personal or private interest:

(i) Is, with respect to the public official, public employee or public member, an interest which is direct and immediate as opposed to speculative and remote; and

(ii) Is an interest that provides the public official, public employee or public member, a greater benefit or a lesser detriment than it does for a large or substantial group or class of persons who are similarly situated.

(b) A public official, public member or public employee described by subsection (a) of this section shall abstain from voting on the decision and from making any official decision in the matter. The public official's, public member's or public employee's abstention from voting must be recorded in the governmental entity's official records.

(c) This section shall not be construed to supersede W.S. 15-9-220 , 16-6-118 or 16-9-203(f) . Those provisions shall control to the extent inconsistent with this section.
