A plaintiff may waive a portion of his claim of more than $12,000 so as to bring the matter within the monetary jurisdiction of the municipal court. Such waiver shall be revoked automatically if the defendant appeals the final order of the municipal court. In cases under this paragraph the defendant shall have no right of trial by jury in the municipal court, but shall have the right to appeal for trial de novo, including the right of trial by jury, to the court of common pleas, in accordance with local rules of court established by the administrative judge of the trial division. These rules shall not be inconsistent with Statewide rules of procedure as established by the Supreme Court. It is the purpose of this paragraph to establish an expeditious small claims procedure whereby it shall not be necessary for the litigants to obtain counsel. Judgments by confession shall not be entered in the municipal court.
