In Schenck v. Pittsburgh, 364 Pa. 31, 70 A.2d 612 (1950), an objecting property owner argued that mere certification of a parcel as blighted did not conclusively establish that it would be used for a public purpose, but the Supreme Court stated that in the absence of any indication that the agency acted in bad faith or was wholly arbitrary in certifying the area, a certification was not subject to judicial review.
