Summoning of person within this state to appear as witness in another state.
Wyo. Stat. Ann. § 7-11-404
in effect(a) If a judge of a court of record in any state which by its laws has made provision for commanding persons within that state to attend and testify in criminal prosecutions in this state certifies under the seal of the court that there is a criminal prosecution pending in such court, that a person being within this state is a material witness in the prosecution, and that his presence will be required for a specified number of days, upon presentation of the certificate to any judge of a court of record in the county in which such person is, the judge shall fix a time and place for hearing and shall notify the witness of the time and place.
(b) If at the hearing the judge determines that the witness is material and necessary, that it will not cause undue hardship to the witness to be compelled to attend and testify in the prosecution in the other state and that the laws of the state in which the prosecution is pending and of any other state through which the witness may be required to pass by ordinary course of travel will give to him protection from arrest and the service of civil and criminal process, he shall issue a summons with a copy of the certificate attached, directing the witness to attend and testify in the court where the prosecution is pending at a time and place specified in the summons.
(c) A witness who is summoned to attend and testify in a criminal prosecution in another state as provided by this section, shall not be compelled to attend unless he is paid or tendered by some properly authorized person compensation including mileage for each mile traveled by the ordinary route to and from the court where the prosecution is pending and witness fees for each day that he is required to travel and attend as a witness. The mileage and witness fees shall be at the same rate paid other witnesses under the laws of the state requiring attendance. A witness who has been paid or tendered the compensation required by this subsection and who fails without good cause to attend and testify as directed in the summons, shall be punished in a manner provided for the punishment of any witness who disobeys a summons issued from a court of record in this state.
