(a) When a temporary injunction is granted in any action before its return day, it may be dissolved or modified by the Superior Court or by any judge of the Superior Court. A written motion for dissolution shall be preferred before the return day.
(b) After the return day, a motion to dissolve a temporary injunction shall be addressed to the court location in which the action is pending, or, if the court at such location is not actually in session, to a judge thereof. If the judge is unable for any reason to hear the motion, it shall be heard and determined by the superior court at another location or by any other judge of the Superior Court.
