Mo. Rev. Stat. § 92.092

All provisions of sections 92.074 to 92.089 are so essentially and inseparably connected with, and so dependent upon, each other that no such provision would be enacted without all others. If a court of competent jurisdiction enters a final judgment on the merits that is not subject to appeal and that declares any provision or part of sections 92.074 * to 92.089 unconstitutional or unenforceable then sections 92.074 to 92.089, in their collective entirety, are invalid and shall have no legal effect as of the date of such judgment. In such event, both telecommunications companies and municipalities shall have the same rights as existed before August 28, 2005, but shall not be entitled to reimbursement, or required to pay reimbursement, for any sums paid in the good faith belief in the validity and constitutionality of sections 92.074 to 92.089.
