Section 310.30. Jury deliberation; request for information

At  any  time  during its deliberation, the jury may request the court
  for further instruction or information with respect  to  the  law,  with
  respect  to  the  content  or  substance  of any trial evidence, or with
  respect to any other matter pertinent to the jury's consideration of the
  case.  Upon such a request, the court  must  direct  that  the  jury  be
  returned  to  the  courtroom  and,  after  notice to both the people and
  counsel for the defendant, and in the presence of  the  defendant,  must
  give  such  requested  information  or  instruction  as  the court deems
  proper. With the consent of the parties and upon the request of the jury
  for further instruction with respect to a statute, the  court  may  also
  give  to  the  jury  copies  of  the  text  of any statute which, in its
  discretion, the court deems proper.
