3575.Substitution of Alternate Juror: During Deliberations (Pen.
Code, § 1089)
One of your fellow jurors has been excused and an alternate juror has
been selected to join the jury.
Do not consider this substitution for any purpose.
The alternate juror must participate fully in the deliberations that lead
to any verdict. The People and the defendant[s] have the right to a
verdict reached only after full participation of the jurors whose votes
determine that verdict. This right will only be assured if you begin your
deliberations again, from the beginning. Therefore, you must set aside
and disregard all past deliberations and begin your deliberations all
over again. Each of you must disregard the earlier deliberations and
decide this case as if those earlier deliberations had not taken place.
Now, please return to the jury room and start your deliberations from
New January 2006
The court has a sua sponte duty to give this instruction if an alternate juror has
been seated. (People v. Collins (1976) 17 Cal.3d 687, 693–694 [131 Cal.Rptr. 782,
552 P.2d 742], overruled on other grounds in People v. Boyette (2002) 29 Cal.4th
381, 462, fn. 19 [127 Cal.Rptr.2d 544, 58 P.3d 391].)
If an alternate juror is seated during the penalty phase of a capital trial but prior to
submission of the penalty phase to the jury, give CALCRIM No. 3576, Substitution
of Alternate Juror in Capital Case: After Guilt Determination, Before Submission of
Penalty Phase to Jury.
