Wyo. R. Prac. & P. 33
The court on motion of a defendant may grant a new trial to that defendant if required in the interest of justice. If trial was by the court without a jury, the court, on motion of a defendant for a new trial, may vacate the judgment if entered, take additional testimony, and direct the entry of a new judgment.
A motion for a new trial based on any grounds, except newly discovered evidence, shall be made within 15 days after verdict or finding of guilty or within such further time as the court may fix during the 15 day period; but the time for filing of motion may not be extended to a day more than 30 days from the date the verdict or finding of guilty is returned. The motion shall be determined and a dispositive order entered within 15 days after the motion is filed and if not so entered shall be deemed denied, unless within that period the determination shall be continued by order of the court, but no continuance shall extend the time to a day more than 60 days from the date the verdict or finding of guilty is returned.
A motion for a new trial based on the grounds of newly discovered evidence may be made only before or within two years after final judgment but if an appeal is pending, the court may grant the motion only on remand of the case. A motion for new trial based on the ground of newly discovered evidence shall be heard and determined and a dispositive order entered within 30 days after the motion is filed unless, within that time, the determination is continued by order of the court, but no continuance shall extend the time to a day more than 60 days from the date that the original motion was filed. When disposition of a motion for new trial based on newly discovered evidence is made without hearing, the order shall include a statement of the reason for determination without hearing.
