JEFFERSON CITY, Mo. (AP) – The state House is expected to debate legislation this week that would prohibit Missouri’s minimum wage from exceeding the federal minimum wage. It’s just one example of how lawmakers have more frequently sought to undo voter-approved laws. About three-fourths of Missouri voters passed a minimum wage law in 2006 that included an annual inflationary adjustment. By capping Missouri’s minimum wage at the federal level, lawmakers would essentially negate that measure. Committees in the House and Senate also have advanced legislation that would repeal parts of an initiative approved last November by voters that toughened laws for dog breeders. If lawmakers act soon, they could revoke parts of the dog law before it takes effect this November. Some lawmakers say the voter-approved measures could drive up business costs, resulting in layoffs.
