Many of the Abell recommendations mirror legislation that was introduced — but did not pass — during this year’s legislative session that ended in April. The bills were filed at the guidance of a state Department of Human Services work group made up of advocates, private attorneys and policymakers who studied the system. The state is required to make some of the changes under 2016 rules adopted by the outgoing Obama administration, and stakeholders expect some of the proposals will be reintroduced when lawmakers return to Annapolis in January.
