Mo. Const. art. X, § 11(g)

The school board of any school district whose operating levy for school purposes for the 1995 tax year was established pursuant to a federal court order may establish the operating levy for school purposes for the district at a rate that is lower than the court-ordered rate for the 1995 tax year. The rate so established may be changed from year to year by the school board of the district. Approval by a majority of the voters of the district voting thereon shall be required for any operating levy for school purposes equal to or greater than the rate established by court order for the 1995 tax year. The authority granted in this section shall apply to any successor school district or successor school districts of such school district. [Effective - 07 May 1998 , see footnote]
