In all cases, civil and criminal, there shall be allowed as a matter of right at least one appeal to another court, except that the Commonwealth may not appeal from a judgment of acquittal in a criminal case, other than for the purpose of securing a certification of law, and the General Assembly may prescribe that there shall be no appeal from that portion of a judgment dissolving a marriage. Procedural rules shall provide for expeditious and inexpensive appeals. Appeals shall be upon the record and not by trial de novo.
