in effectWyo. Stat. Ann. § 1-28-102 Causes for injunction; granting temporary order.
When it appears by the petition that the plaintiff is entitled to relief consisting of restraining the commission or continuance of some act the commission or continuance of which during the litigation would produce great or irreparable injury to the plaintiff, or when during the litigation it appears that the defendant is doing, threatens to do, or is procuring to be done some act in violation of the plaintiff's rights respecting the subject of the action and tending to render the judgment ineffectual, a temporary order may be granted restraining the act. The order may also be granted in any case where it is specially authorized by statute and by municipal ordinance adopted pursuant to W.S. 15-1-103(a)(xlvi).
Wyo. Stat. Ann. § 1-28-103 When and by whom granted.
The injunction may be granted at the time of commencing the action, or at any time before judgment, by the district court or a judge thereof, or in the absence from the county of the judge, by the court commissioner of the county, when it appears by affidavit of the plaintiff or his agent that the plaintiff is entitled thereto. When an injunction has been vacated during the pendency of the action in the district court, and an appeal is taken to the supreme court from the judgment or final order after trial in the district court, an injunction may be granted at any time before judgment or final order in the supreme court by a judge of the supreme court, when it appears to the court or judge by affidavit of the party or his agent that the party is entitled thereto. Upon like proof, an injunction may also be allowed by the supreme or district court or by a judge of either as a temporary remedy, during the pendency of a case on error or appeal.
Wyo. Stat. Ann. § 1-28-104 Order of injunction and notice.
The order of injunction shall be addressed to the party enjoined and shall state the injunction. When the injunction is allowed at the commencement of the action, the clerk shall endorse upon the summons "injunction allowed", and it is not necessary to issue the order of injunction; nor is it necessary to issue the order when notice of the application has been given to the party enjoined. Service of the summons so endorsed or the notice of the application for an injunction is notice of its allowance.
Wyo. Stat. Ann. § 1-28-105 Injunction operative from time of notice.
An injunction shall bind the party from the time he has notice and the bond required is executed.
Wyo. Stat. Ann. § 1-28-106 When second application for injunction denied.
No injunction shall be granted by a judge after a motion therefor has been overruled by his court on the merits of the application. When it has been refused by the court in which the action is brought, or a judge thereof, it shall not be granted to the same applicant by a court of inferior jurisdiction, or any judge thereof.
Wyo. Stat. Ann. § 1-28-107 Enforcement of injunction; penalties.
An injunction or restraining order granted by a judge may be enforced as the act of the court, and disobedience may be punished by the court as a contempt. An attachment may be issued against the disobedient party upon satisfactory showing by affidavit of the breach of the injunction or restraining order. The disobedient party may be required by the court or judge to pay a fine not exceeding two hundred dollars ($200.00), to make immediate restitution to the party injured and to give further security to obey the injunction or restraining order. In default thereof, he may be committed to custody until he complies with the requirements or is otherwise legally discharged. Fines collected under this section shall be paid to the state treasurer and credited as provided in W.S. 8-1-109.
Wyo. Stat. Ann. § 1-28-108 Additional security may be required.
At any time before judgment, upon reasonable notice to the party who obtained the injunction, a party enjoined may move the court or judge for additional security. If it appears that the surety has removed from the state or is insufficient, the court may vacate the injunction unless in a reasonable time sufficient security is given.
Wyo. Stat. Ann. § 1-28-109 Affidavits used on hearing.
On the hearing of an application for an injunction, each party may read affidavits, and all affidavits shall be filed.
Wyo. Stat. Ann. § 1-28-110 Motion to vacate or modify injunction.
When an injunction has been granted a party may, before trial, apply to the court in which the action is pending, or a judge thereof, or to the supreme court or a judge thereof, to vacate or modify the same. The party applying for vacation or modification shall give the adverse party reasonable notice of the time and place for hearing the motion. The application may be made upon the petition and affidavits upon which the injunction was granted, or upon affidavits of the party enjoined, with or without answer.
Wyo. Stat. Ann. § 1-28-111 Evidence on hearing of motion.
When the application is made upon affidavits of the defendant but not otherwise, the plaintiff may oppose the same by affidavits or other evidence in addition to the evidence on which the injunction was granted.
