HB 4803 establishes new district attorney offices for four regional districts in Texas: Northeast Texas, Central Texas, Southeast Texas, and South Texas. It grants these newly created district attorneys the authority to represent the state in all cases before the district courts within their respective regions. The bill defines the counties included in each regional district and outlines the election process for the district attorneys. It also sets forth their jurisdiction, responsibilities, and operational framework, ensuring that each regional district attorney has the necessary legal powers to prosecute cases within their assigned areas.
