Pa. Const. art. V, § 10

(a) The Supreme Court shall exercise general supervisory and administrative authority over all the courts and justices of the peace, including authority to temporarily assign judges and justices of the peace from one court or district to another as it deems appropriate.

(b) The Supreme Court shall appoint a court administrator and may appoint such subordinate administrators and staff as may be necessary and proper for the prompt and proper disposition of the business of all courts and justices of the peace.

(c) The Supreme Court shall have the power to prescribe general rules governing practice, procedure and the conduct of all courts, justices of the peace and all officers serving process or enforcing orders, judgments or decrees of any court or justice of the peace, including the power to provide for assignment and reassignment of classes of actions or classes of appeals among the several courts as the needs of justice shall require, and for admission to the bar and to practice law, and the administration of all courts and supervision of all officers of the Judicial Branch, if such rules are consistent with this Constitution and neither abridge, enlarge nor modify the substantive rights of any litigant, nor affect the right of the General Assembly to determine the jurisdiction of any court or justice of the peace, nor suspend nor alter any statute of limitation or repose. All laws shall be suspended to the extent that they are inconsistent with rules prescribed under these provisions. Notwithstanding the provisions of this section, the General Assembly may by statute provide for the manner of testimony of child victims or child material witnesses in criminal proceedings, including the use of videotaped depositions or testimony by closed-circuit television.

(d) The Chief Justice and president judges of all courts with seven or less judges shall be the justice or judge longest in continuous service on their respective courts; and in the event of his resignation from this position the justice or judge next longest in continuous service shall be the Chief Justice or president judge. The president judges of all other courts shall be selected for five-year terms by the members of their respective courts. A Chief Justice or president judge may resign such position and remain a member of the court. In the event of a tie vote for office of president judge in a court which elects its president judge, the Supreme Court shall appoint as president judge one of the judges receiving the highest number of votes.

(e) Should any two or more justices or judges of the same court assume office at the same time, they shall cast lots forthwith for priority of commission, and certify the results to the Governor who shall issue their commissions accordingly.
