Section 103.56 - Injunctions: conditions of issuance; restraining orders(1) No court shall have jurisdiction to issue a temporary or permanent injunction in any case involving or growing out of a labor dispute, except after hearing the testimony of witnesses in open court, with opportunity for cross-examination, in support of the allegations of a complaint made under oath, and testimony in opposition to the allegations of the complaint, if offered, and except after findings of all of the following facts by the court: (a) That unlawful acts have been threatened or committed and will be executed or continued unless restrained.(b) That substantial and irreparable injury to complainant's property will follow unless the relief requested is granted.(c) That as to each item of relief granted greater injury will be inflicted upon the complainant by the denial of that relief than will be inflicted upon the defendants by the granting of that relief.(d) That the relief to be granted does not violate s. 103.53.(e) That the complainant has no adequate remedy at law.(f) That the public officers charged with the duty to protect complainant's property have failed or are unable to furnish adequate protection.(2) A hearing under sub. (1) shall be held after due and personal notice of the hearing has been given, in the manner that the court shall direct, to all known persons against whom relief is sought, and also to those public officers who are charged with the duty to protect the complainant's property.(3) If a complainant alleges that a substantial and irreparable injury to the complainant's property will be unavoidable unless a temporary restraining order is issued before a hearing under sub. (1) may be had, a temporary restraining order may be granted on reasonable notice of application for the temporary restraining order as the court may direct by order to show cause, but in no case less than 48 hour's notice. The order to show cause shall be served upon the party or parties that are sought to be restrained and that are specified in the order. The order shall be issued only upon testimony under oath or, in the discretion of the court, upon affidavits, sufficient, if sustained, to justify the court in issuing a temporary injunction upon a hearing as provided for under this section.(4) A temporary restraining order issued under sub. (3) shall be effective for no longer than 5 days and, at the expiration of the 5-day period, shall become void and not subject to renewal or extension, except that if the hearing for a temporary injunction begins before the expiration of the 5-day period the restraining order may in the court's discretion be continued until a decision is reached on the issuance of the temporary injunction.(5) No temporary restraining order or temporary injunction may be issued under this section except on condition that the complainant first files an undertaking with adequate security sufficient to compensate those enjoined for any loss, expense, or damage caused by the improvident or erroneous issuance of the order or injunction, including all reasonable costs, reasonable attorney fees and expenses that will be incurred in opposing the order or the granting of any injunctive relief sought in the same proceeding and subsequently denied by the court.(6) The undertaking required under sub. (5) shall represent an agreement between the complainant and the surety upon which a decree may be rendered in the same suit or proceeding against the complainant and surety, the complainant and surety submitting themselves to the jurisdiction of the court for that purpose. However, nothing contained in this section deprives any party having a claim or cause of action under or upon an undertaking filed under sub. (5) from electing to pursue an ordinary remedy by suit at law or in equity.1993 a. 492; 1997 a. 253; 2005 a. 253. Sub. (1) and s. 103.62 [now s. 103.505], relating to limitations upon the jurisdiction of a court to issue injunctions in cases arising from labor disputes, are inapplicable to actions brought by the state or its political subdivisions against public employees.
