Indiana Code Title 13. Environment § 13-29-1-10

Sec. 10.

The provisions of this compact shall be severable and if any provision of this compact is finally determined by a court of competent jurisdiction to be contrary to the Constitution of any participating state or of the United States or the application thereof to any person or circumstance is held invalid, the validity of the remainder of this compact to that person or circumstance and the applicability of the entire compact to any other person or circumstance shall not be affected thereby.  If any provision of this compact shall be held contrary to the Constitution of any state participating therein, the compact shall remain in full force and effect as to the state affected as to all severable matters.  If any provision of this compact imposing a financial obligation upon a party state, or a state that has withdrawn from this compact or had its membership in this compact revoked, is finally determined by a court of competent jurisdiction to be unenforceable due to the state's constitutional limitations on its ability to pay the obligation, then that state shall use its best efforts to obtain an appropriation to pay the obligation, and, if the state is a party state, its right to have waste generated within its borders disposed of at compact facilities, or any noncompact facility made available to the region by any agreement entered into by the Commission pursuant to Article III(h)(6) of this compact, shall be suspended until the appropriation is obtained.
