In Guiser v. Seiber the Superior Court quashed the appeal, in part, because the appellant did not wait for the trial court to rule on post-sentence motions and enter judgment. But the Court reviewed an order granting injuctive relief because a party has a right to appeal immediately from such relief. The Court held that the trial court failed to adequately address whether municipalities were indispensable parties to the litigation. The Court noted that failure to join an indispensible party implicates the jurisdiction of a court and thus the matter was remanded to determine that issue.
