(a)Arrest; Availability of Remedy. Except in cases of civil contempt or as specifically authorized by law, no civil arrest shall be permitted in connection with any action under these rules, except as provided in section (c) of this rule. (b)Deleted.(c)Ne Exeat. An order of arrest may be entered upon motion with or without notice when the plaintiff has obtained a judgment or order requiring the performance of an act, the neglect or refusal to perform which would be punishable by the court as a contempt, and where the defendant is not a resident of the Commonwealth or is about to depart therefrom, by reason of which nonresidence or departure there is danger that such judgment or order will be rendered ineffectual. The motion shall be accompanied by an affidavit showing that the plaintiff is entitled to the relief requested. The court may fix such terms as are just, and shall in any event afford the defendant an opportunity to obtain his release by the giving of an appropriate bond. In this rule the words “plaintiff’ and “defendant” mean respectively the party who has obtained the judgment or order and the person whose arrest is sought.
