In Citizens Against Gambling Subsidies Pittsburgh Palisades Park, LLC v. Commonwealth, 585 Pa. 196, 888 A.2d 655 (2005), the Supreme Court recognized: By virtue of Section 702 of the Administrative Agency Law, neither party status nor traditional aggrievement is necessary to challenge actions of an administrative agency. Rather, standing to appeal administrative decisions extends to "persons," including non-parties, who have a "direct interest" in the subject matter, as distinguished from a "direct, immediate and substantial" interest. A direct interest requires a showing that the matter complained of caused harm to the person's interest. Although not the full equivalent of "direct, immediate and substantial," the direct interest requirement retains the function of differentiating material interests that are discrete to some person or limited class of persons from more diffuse ones that are common among the citizenry. 591 Pa. at 319, 916 A.2d at 628
