As a general rule, the municipal courts are not "courts of record" (i.e., no court reporter recorded and transcribed the proceedings), and thus an appeal to the county level would require a whole new trial (i.e., a trial "de novo"). This proved to be a loophole for some defendants in traffic cases, who betted on the officer not being able to attend, and thus having the case dismissed. Furthermore, the de novo trials crowded the dockets of already busy county courts at law. Many major cities—such as those in Austin, El Paso, Houston, Dallas and San Antonio—have chosen to convert their municipal courts to courts of record (this also requires voter approval) to close this loophole.
