The hearing shall be conducted in accordance with Section 908 of the Pennsylvania Municipalities Planning Code, Act 247, as amended, and all references therein to the Zoning Hearing Board shall, for purposes of this section, be references to "Township Council"; provided, however, that the provisions of the Pennsylvania Municipalities Planning Code, as amended, Section 908, Subsections (1.2) and (9), shall not apply, and the provisions of Section 916.1 shall control. If O'Hara Township does not accept a landowner's curative amendment brought in accordance with this subsection and a court subsequently rules that the challenge has merit, the court's decision shall not result in a declaration of invalidity for the entire Zoning Ordinance and map, but only for those provisions which specifically relate to the landowner's curative amendment and challenge.
