Wyo. Stat. § 1-11-105
If a person exempt from jury duty is summoned as a juror, he may submit a declaration under penalty of perjury stating his purported grounds for exemption. If the court determines that the declaration sufficiently demonstrates that the person is not required to serve as a juror pursuant to W.S. 1-11-103(a), the court shall discharge the person from serving as a trial juror for the jury term in which he was summoned. A person who is discharged under this section is not required to appear in court. Failure of any person who is exempt to submit a declaration under penalty of perjury is a waiver of his exemption, and he is required to appear upon the day for which the jury is summoned and serve as a juror the same as if he were not entitled to exemption unless otherwise excused by the court.
