(a) A landowner who, on substantive grounds, desires to challenge the validity of an ordinance or map or any provision thereof which prohibits or restricts the use or development of land in which he has an interest shall submit the challenge either:

(b) Persons aggrieved by a use or development permitted on the land of another by an ordinance or map, or any provision thereof, who desires to challenge its validity on substantive grounds shall first submit their challenge to the zoning hearing board for a decision thereon under section 909.1(a)(1).

(c) The submissions referred to in subsections (a) and (b) shall be governed by the following:

(d) The zoning hearing board or governing body, as the case may be, shall commence its hearings within 60 days after the request is filed unless the landowner requests or consents to an extension of time.

(e) Public notice of the hearing shall include notice that the validity of the ordinance or map is in question and shall give the place where and the times when a copy of the request, including any plans, explanatory material or proposed amendments may be examined by the public.

(f) The challenge shall be deemed denied when:

(g) Where, after the effective date of this act, a curative amendment proposal is approved by the grant of a curative amendment application by the governing body pursuant to section 909.1(b)(4) or a validity challenge is sustained by the zoning hearing board pursuant to section 909.1(a)(1) or the court acts finally on appeal from denial of a curative amendment proposal or a validity challenge, and the proposal or challenge so approved requires a further application for subdivision or land development, the developer shall have two years from the date of such approval to file an application for preliminary or tentative approval pursuant to Article V or VII.³ Within the two-year period, no subsequent change or amendment in the zoning, subdivision or other governing ordinance or plan shall be applied in any manner which adversely affects the rights of the applicant as granted in the curative amendment or the sustained validity challenge. Upon the filing of the preliminary or tentative plan, the provisions of section 508(4)⁴ shall apply. Where the proposal appended to the curative amendment application or the validity challenge is approved but does not require further application under any subdivision or land development ordinance, the developer shall have one year within which to file for a building permit. Within the one-year period, no subsequent change or amendment in the zoning, subdivision or other governing ordinance or plan shall be applied in any manner which adversely affects the rights of the applicant as granted in the curative amendment or the sustained validity challenge. During these protected periods, the court shall retain or assume jurisdiction for the purpose of awarding such supplemental relief as may be necessary.

(h) Where municipalities have adopted a multimunicipal comprehensive plan pursuant to Article XI⁵ but have not adopted a joint municipal ordinance pursuant to Article VIII-A⁶ and all municipalities participating in the multimunicipal comprehensive plan have adopted and are administering zoning ordinances generally consistent with the provisions of the multimunicipal comprehensive plan and a challenge is brought to the validity of a zoning ordinance of a participating municipality involving a proposed use, then the zoning hearing board or governing body, as the case may be, shall consider the availability of uses under zoning ordinances within the municipalities participating in the multimunicipal comprehensive plan within a reasonable geographic area and shall not limit its consideration to the application of the zoning ordinance on the municipality whose zoning ordinance is being challenged.

(i) A landowner who has challenged on substantive grounds the validity of a zoning ordinance or map either by submission of a curative amendment to the governing body under subsection (a)(2) or to the zoning hearing board under section 909.1(a)(1) shall not submit any additional substantive challenges involving the same parcel, group of parcels or part thereof until such time as the status of the landowner's original challenge has been finally determined or withdrawn: Provided, however, That if after the date of the landowner's original challenge the municipality adopts a substantially new or different zoning ordinance or zoning map, the landowner may file a second substantive challenge to the new or different zoning ordinance or zoning map under subsection (a).
