In any case where the Borough Council disapproves a subdivision plan, any person aggrieved thereby may, within 30 days thereafter, appeal therefrom by petition to the Court of Common Pleas wherein such subdivision is located, which court shall hear the matter de novo and, after hearing, enter a decree affirming, reversing or modifying the action of the Council, as may appear just in the premises. The Court shall designate the manner in which notices of the hearing of such appeal shall be given to all parties interested. The decisions of the Court shall be final.
