UJI 13-113. The court.

It is my job to preside over the trial, decide and instruct on questions of law and rule upon what evidence may be admitted for your consideration. No gesture, remark or comment I make should influence your decision in this case. At times I may ask questions of witnesses. If I do, such questions do not in any way indicate my opinion about the facts or indicate the weight I feel you should give to the testimony of the witness.
