210 Pa. Code r. 104
Under 42 Pa.C.S. § 323 (powers) every court has, except as otherwise prescribed by general rules, power to make such rules and orders of court as the interest of justice or the business of the court may require.
All rules of court must be adopted in compliance with Pa. R.J.A. No. 103, which (except in the case of Supreme Court rules of court) requires filing in the Administrative Office prior to the effectiveness of such rules.
Rules contained in Chapters 33, 35 and 37 applicable to a particular appellate court should always be examined to determine whether they have superseded provisions of these rules applicable to appellate courts generally. Also, review of any applicable internal operating procedures may afford material guidance. See, e.g. 210 Pa. Code Ch. 67 (internal operating procedures of the Commonwealth Court).
