I do not know what happened, but, yes, if a judge fails to follow procedure, then that is a problem. The trial of Sharon Keller started yesterday. She is presiding judge of the Court of Criminal Appeals. That means, she is the chief judge for the highest court in Texas regarding criminal cases. If she did know that attorneys for Michael Richard were calling for more time and she did not give them that time, then, yes, that would be a pretty clear violation of something.
The trial is starting out not too well for Judge Keller. Another judge on the Court of Criminal Appeals disagrees with Judge Keller on a key fact: did anyone tell Judge Cheryl Johnson, the duty judge that day, about the call asking for more time? Judge Johnson says no, no one told her. If so, that would be a pretty clear breach of procedure.
The State Commission on Judicial Conduct used to be a fairly weak organization. But, some ten years ago, they started to truly enforce judicial ethics. This is by far the biggest case they have taken on. But, if the allegations prove to be true, it is one of the more egregious cases they have dealt with to my knowledge.
