Missouri’s judges could be due a multi-million-dollar pay increase if their counterparts in the federal government win a court case seeking a retroactive pay hike. The potential pay increase could affect more than 400 judges in Missouri. It even could lead to pay increases for dozens of full-time local prosecutors. The administrative arm of Missouri’s court system has prepared a budget request for the next year estimating the potential judicial pay increase could cost nearly $6.7 million. Counties could collectively be on the hook for an additional $1 million for prosecutors.
