Rule *903 - Bill of Costs(a)Affidavit. The affidavit of the party or other person to the correctness of the bill and the attendance and materiality of the witnesses shall be annexed, and shall be prima facie evidence to the taxing officer.(b)Taxation. Bills of costs shall be taxed, in the first instance, by the Prothonotary upon application of the party entitled to execution, subject to exceptions, which exceptions shall be filed on or before the return day of the execution. A re-taxation shall then be had before the Prothonotary upon ten (10) days notice thereof to both parties, from which either party may appeal to the Court within five days thereafter, provided that the appellant shall, within three days after appeal is entered, file a specification of the items to which appellant objects and the grounds of all objections; otherwise, the appeal will be dismissed. No exceptions or appeal shall operate to stay execution or prevent the collection of the debt or costs; but when collected on execution or paid into Court, the costs excepted to will be retained until the question is decided.
