In labor-dispute cases, a court may not issue temporary or permanent injunctive relief unless it first holds the required hearing, makes specific findings, and the complainant files an adequate security undertaking.
§844. Injunctions and restraining orders, grounds for issuance; proof required No court shall issue a temporary or permanent injunction in any case involving or growing out of a labor dispute, as herein defined, 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 thereto, if offered, and except after findings of fact by the court to the effect: (1) That unlawful acts have been threatened or committed and will be executed or continued unless restrained; (2) That substantial and irreparable injury to complainant's property will follow unless the relief requested is granted; (3) That as to each item of relief granted greater injury will be inflicted upon complainant by the denial thereof than will be inflicted upon the defendants by the granting thereof; (4) That no item of relief granted is relief that a court has no authority to restrain or enjoin under R.S. 23:841; (5) That complainant has no adequate remedy by ordinary legal procedure; and (6) That the public officers charged with the duty to protect complainant's property have failed or are unable to furnish adequate protection. Such hearing shall be held after due and personal notice thereof has been given, in such manner as the court shall direct, to all known persons against whom relief is sought, and also to those public officers charged with the duty to protect complainant's property. If a complainant shall also allege that unless a temporary restraining order is issued before such hearing can be had a substantial and irreparable injury to complainant's property will be unavoidable, such a temporary restraining order may be granted upon the expiration of such reasonable notice of application therefor as the court may direct by order to show cause, but in no case less than forty-eight hours. Such order to show cause shall be served upon such party or parties as are sought to be restrained and as shall be specified in said order, and the restraining order shall issue only upon testimony, 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 herein provided for. Such a temporary restraining order shall be effective for no longer than five days, at the expiration of which time it shall become void and not subject to renewal or extension; provided, that if the hearing for a temporary injunction shall have been begun before the expiration of the said five days the restraining order may, in the court's discretion, be continued until a decision is reached upon the issuance of the temporary injunction. No temporary restraining order or temporary injunction shall be issued except on condition that complainant shall first file an undertaking with adequate security sufficient to recompense those enjoined for any loss, expense, or damage caused by the improvident or erroneous issuance of such order or injunction, including all reasonable costs, together with a reasonable attorney's fee, and expense against the order or against the granting of any injunctive relief sought in the same proceeding and subsequently denied by the court. The undertaking herein mentioned shall be understood to signify an agreement entered into by the complainant and the surety upon which a decree may be rendered in the same suit or proceeding against the said complainant and surety, the said complainant and surety submitting themselves to the jurisdiction of the court for that purpose. But nothing herein contained shall deprive any party having a claim or cause of action under or upon such undertaking from electing to pursue his ordinary remedy by suit at law.
