New York Consolidated Laws, Criminal Procedure Law - CPL § 270.55 Sentencing jury in capital cases

During the period extending from when a jury returns a verdict of guilty upon a count of an indictment charging murder in the first degree as defined by section 125.27 of the penal law until a jury retires to deliberate on the sentence pursuant to section 400.27, the court may in its discretion either permit the jurors to separate during recesses and adjournments or direct that they be continuously kept together during such periods under the supervision of an appropriate public servant or servants.  In the latter case, such public servant or servants may not speak to or communicate with any juror concerning any subject connected with the sentencing proceeding nor permit any other person to do so, and must return the jury to the court room at the next designated session.  Unless otherwise provided for in section 400.27, the provisions of sections 270.35, 270.40 and 270.50 shall govern the sentencing proceeding provided for in section 400.27.
