JEFFERSON CITY, Mo. (AP) — The Missouri Supreme Court has struck down a 2018 state law that imposed new requirements on some public sector labor unions. In a 5-2 ruling Tuesday, the Supreme Court said the law violated the constitution’s equal protection rights by exempting public safety unions from the new requirements imposed on other types of unions. The law passed by the Republican-led Legislature required other public sector unions to hold recertification elections every three years and to get annual approval from employees to deduct dues from paychecks. The Supreme Court majority said there was no rational basis to treat public safety unions differently.
