210 Pa. Code § 65.9
A member of staff owes a duty of confidentiality to the judges of the Superior Court. This duty extends to matters concerning any opinions, statements, or events with respect to the decision-making process of the Court. A staff member should avoid even informal contact with attorneys or litigants with respect to a matter pending before the Court. An attorney should refrain from discussions outside the Court, public or private, regarding the merits of pending proceedings. Matters involving the decision-making process are inappropriate for discussion outside the Court, including but not limited to the assignment of a case to a particular judge, the motions assignment judge, or the identity of the judge who may have signed an order in a case per curiam.
