Wyo. Stat. § 1-12-103 (2026)

and criminal actions.

A party may compel the adverse party to testify orally or by
deposition as any other witness, and no person is disqualified
as a witness in any action, civil or criminal, because of his
interest in the same as a party or otherwise. Every person is a
competent witness except as otherwise provided by law, but his
interest in the action may be shown to affect the credibility of
the witness. Any party of record in a civil action, or any
person for whose immediate benefit the action is prosecuted or
defended, or his assignor, officer, agent or employee or if a
county or city is a party any officer of the county or city, may
be examined upon the trial of any action as if under
cross-examination at the instance of the adverse party and may
be compelled to testify subject to the same rules for
examination as any other witness. The party calling for the
examination is not concluded thereby and may rebut the evidence
given by counter or impeaching testimony.
