Relating to appeals from a justice or municipal court.

HB 4237 changes how criminal appeals from justice or municipal courts work in Texas. It requires court proceedings to pause when a defendant files the required appeal bond (Section 1). For most appeals to county courts, it mandates a full retrial ("de novo") as if the case started there, but appeals from municipal courts of record must be based solely on errors in the existing record (Section 2). This bill directly affects criminal defendants appealing convictions from local courts, altering both the process and scope of their appeals. It takes effect September 1, 2025.
