Modifies provisions governing the compensation of prosecuting attorneys in counties of the third classification

HB 173 establishes salary schedules for prosecuting attorneys in Missouri counties classified as "third class," based on the county's assessed property valuation. Full-time prosecutors receive pay equal to associate circuit judges, while part-time salaries range from $37,000 to $55,000 depending on valuation (e.g., $37,000 for counties with $18-40.9 million in valuation). The bill requires prosecutors to complete 20 hours of annual approved training to earn an additional $2,000, with training costs reimbursable by counties, and mandates state reimbursement of 30% of salaries for third-class counties. This affects all prosecuting attorneys in third-class counties, including city circuit attorneys not within a county.
