La. Stat. tit. 45 § 257
Every order, decision, rule, rate and regulation of the commission adopted under this Chapter shall go into effect at such time as may be fixed by the commission and shall remain in effect and be complied with, unless and until set aside by the commission or by a final judgment of a court of competent jurisdiction in a suit to set aside and annul the same. But nothing contained in this Section shall deny to any court of competent jurisdiction the right to suspend such order, decision, rule, rate or regulation by injunction or otherwise, upon bond in amount and condition as may be fixed by the court; provided that in the event such order or injunction is set aside by final judgment, any parties showing interest and injury may sue and recover on the bond.
