The Children and Families Committee is responsible by law for carrying out interim studies and monitoring the activities of the Department of Public Health and Human Services. Senate Bill 423 in 2011 also gave the committee the responsibility of monitoring implementation of the Montana Marijuana Act, which replaced the former Montana Medical Marijuana Act.
Committee members decided in September 2015 to have only a minimal level of involvement in monitoring activities stemming from the passage this year of Senate Bill 405, to expand Medicaid to childless, nondisabled adults, and Senate Bill 411, requiring closure of the Montana Developmental Center. Two executive-branch committees made up of legislative and gubernatorial appointees and under the jurisdiction of the Department of Public Health and Human Services will be working on activities related to those two bills. The Children and Families Committee decided that those two committees could handle most oversight duties.
