Code Civ. Proc., § 630

(a) Unless the court specified an earlier time for making a motion for directed verdict, after all parties have completed the presentation of all of their evidence in a trial by jury, any party may, without waiving his or her right to trial by jury in the event the motion is not granted, move for an order directing entry of a verdict in its favor.

(b) If it appears that the evidence presented supports the granting of the motion as to some, but not all, of the issues involved in the action, the court shall grant the motion as to those issues and the action shall proceed on any remaining issues. Despite the granting of such a motion, no final judgment shall be entered prior to the termination of the action, but the final judgment, in addition to any matter determined in the trial, shall reflect the verdict ordered by the court as determined by the motion for directed verdict.

(c) If the motion is granted, unless the court in its order directing entry of the verdict specifies otherwise, it shall operate as an adjudication upon the merits.

(d) In actions which arise out of an injury to a person or property, when a motion for directed verdict was granted on the basis that a defendant was without fault, no other defendant during trial, over plaintiff’s objection, shall attempt to attribute fault to or comment on the absence or involvement of the defendant who was granted the motion.

(e) The order of the court granting the motion for directed verdict is effective without any assent of the jury.

(f) When the jury for any reason has been discharged without having rendered a verdict, the court on its own motion or upon motion of a party, notice of which was given within 10 days after discharge of the jury, may order judgment to be entered in favor of a party whenever a motion for directed verdict for that party should have been granted had a previous motion been made. Except as otherwise provided in Section 12a, the power of the court to act under the provisions of this section shall expire 30 days after the day upon which the jury was discharged, and if judgment has not been ordered within that time the effect shall be the denial of any motion for judgment without further order of the court.
