(a) If any clause, sentence, paragraph or part of this act, or the application thereof, to any person or circumstance, shall, for any reason, be adjudged by a court of competent jurisdiction to be invalid, such judgment shall not affect, impair or invalidate the remainder of this act nor the application of such clause, sentence, paragraph or part to other persons or circumstances, but shall be confined in its operation to the clause, sentence, paragraph or part thereof and to the persons or circumstances directly involved in the controversy in which such judgment shall have been rendered. It is hereby declared to be the legislative intent that this act would have been adopted had such provisions not been included or such persons or circumstances been expressly excluded from their coverage.

(b) Notwithstanding the provisions of subsection (a), if any clause, sentence, paragraph or part of this act, or the application thereof to any person or circumstance, shall be adjudged by a court of competent jurisdiction or finally determined by the Department of Housing and Urban Development not to be in substantial equivalence with the Fair Housing Act and if such judgment or final determination threatens the loss or reduction of Federal funds to the Commission, all provisions of this amendatory act except the provisions adding subsections (c.1) and (j) to section 9 shall be null and void. The Commission shall, in such event, apply the provisions of 16 Pa. Code §§ 45.8(a) (relating to advertisements) and 45.13(f) (relating to exemptions) which were in effect on March 1, 1997, such provisions having been revived by operation of law.
