Section 340.50. Defendant's presence at trial

1.    Except as provided in subdivision two or three, a defendant must
  be personally present during the trial.
    2.  On motion of a defendant represented by counsel, the court may, in
  the absence of an objection by the people,  issue  an  order  dispensing
  with  the requirement that the defendant be personally present at trial.
  Such an order may be  made  only  upon  the  filing  of  a  written  and
  subscribed statement by the defendant declaring that he waives his right
  to  be  personally  present at the trial and authorizing his attorney to
  conduct his defense.
    3.  A defendant who conducts himself in so disorderly and disruptive a
  manner that his trial cannot be carried on with him in the courtroom may
  be removed from the courtroom if, after he has been warned by the  court
  that  he  will  be removed if he continues such conduct, he continues to
  engage in such conduct.
