HB 4388 clarifies judicial authority and prohibits the delegation of judicial responsibilities. It amends the Government Code to explicitly state that a person holding judicial office cannot abdicate or relinquish their constitutional or statutory duties. It also ensures that all judges, regardless of whether they preside over civil or criminal matters, are subject to the Code of Judicial Conduct. Additionally, the bill prevents county commissioners courts from adopting measures that delegate judicial authority unless specifically authorized by law.
