CCRP 770     

Art. 770.  Prejudicial remarks; basis of mistrial

Upon motion of a defendant, a mistrial shall be ordered when a remark or comment, made within the hearing of the jury by the judge, district attorney, or a court official, during the trial or in argument, refers directly or indirectly to:

(1)  Race, religion, color or national origin, if the remark or comment is not material and relevant and might create prejudice against the defendant in the mind of the jury;

(2)  Another crime committed or alleged to have been committed by the defendant as to which evidence is not admissible;

(3)  The failure of the defendant to testify in his own defense; or

(4)  The refusal of the judge to direct a verdict.

An admonition to the jury to disregard the remark or comment shall not be sufficient to prevent a mistrial.  If the defendant, however, requests that only an admonition be given, the court shall admonish the jury to disregard the remark or comment but shall not declare a mistrial.
