P.R. Laws Ap. tit. 32A, § III, Rule 56.5
No order shall be made under Rule 56 to do or to desist from doing any specific act without serving notice upon the adverse party, unless from specific facts supported by affidavit it clearly appears that the petitioner will sustain irreparable injury, damage or loss before notice and hearing on the petition. Such order ex parte shall be effective upon service of notice thereof. Any party affected thereby may at any time file a motion to modify or to set aside the order and said motion shall be heard at the earliest possible date, but not later than five (5) days after the filing thereof and shall have preference over all other matters. A two-day notice upon the party obtaining the order, or the shortest notice the court may prescribe, shall be sufficient for the purposes of the hearing.
