In any civil action brought pursuant to this chapter in which a temporary restraining order, preliminary injunction, or permanent injunction is sought, it is not necessary to allege or prove at any state of the proceeding that irreparable damage will occur should the temporary restraining order, preliminary injunction, or permanent injunction not be issued or that the remedy at law is inadequate. The temporary restraining order, preliminary injunction, or permanent injunction shall be issued without these allegations and without this proof.
