Mo. Rev. Stat. § 71.675: No class action suits permitted for enforcement or collection of business license taxes imposed on telecommunications companies.

1. Notwithstanding any other provision of law to the contrary, no city or town shall bring any action in federal or state court in this state as a representative member of a class to enforce or collect any business license tax imposed on a telecommunications company. A city or town may, individually or as a single plaintiff in a multiple-plaintiff lawsuit, bring an action in federal or state court in this state to enforce or collect any business license tax imposed on a telecommunications company.

2. Nothing in this section shall be construed to preclude any taxpayer from initiating an action in federal or state court as a representative member of a class seeking injunctive relief against the Missouri department of revenue to enforce the imposition, assessment, or collection of the business license tax provided under sections 92.074 to 92.095.
