Section 1376 Of Chapter 6. Inquiry Into The Competence Of The Defendant Before Trial Or After Conviction From California Penal Code >> Title 10. >> Part 2. >> Chapter 6.
1376
. (a) As used in this section, "intellectual disability" means
the condition of significantly subaverage general intellectual
functioning existing concurrently with deficits in adaptive behavior
and manifested before 18 years of age.
(b) (1) In any case in which the prosecution seeks the death
penalty, the defendant may, at a reasonable time prior to the
commencement of trial, apply for an order directing that a hearing to
determine intellectual disability be conducted. Upon the submission
of a declaration by a qualified expert stating his or her opinion
that the defendant is a person with an intellectual disability, the
court shall order a hearing to determine whether the defendant is a
person with an intellectual disability. At the request of the
defendant, the court shall conduct the hearing without a jury prior
to the commencement of the trial. The defendant's request for a court
hearing prior to trial shall constitute a waiver of a jury hearing
on the issue of intellectual disability. If the defendant does not
request a court hearing, the court shall order a jury hearing to
determine if the defendant is a person with an intellectual
disability. The jury hearing on intellectual disability shall occur
at the conclusion of the phase of the trial in which the jury has
found the defendant guilty with a finding that one or more of the
special circumstances enumerated in Section 190.2 are true. Except as
provided in paragraph (3), the same jury shall make a finding that
the defendant is a person with an intellectual disability or that the
defendant does not have an intellectual disability.
(2) For the purposes of the procedures set forth in this section,
the court or jury shall decide only the question of the defendant's
intellectual disability. The defendant shall present evidence in
support of the claim that he or she is a person with an intellectual
disability. The prosecution shall present its case regarding the
issue of whether the defendant is a person with an intellectual
disability. Each party may offer rebuttal evidence. The court, for
good cause in furtherance of justice, may permit either party to
reopen its case to present evidence in support of or opposition to
the claim of intellectual disability. Nothing in this section shall
prohibit the court from making orders reasonably necessary to ensure
the production of evidence sufficient to determine whether or not the
defendant is a person with an intellectual disability, including,
but not limited to, the appointment of, and examination of the
defendant by, qualified experts. A statement made by the defendant
during an examination ordered by the court shall not be admissible in
the trial on the defendant's guilt.
(3) At the close of evidence, the prosecution shall make its final
argument, and the defendant shall conclude with his or her final
argument. The burden of proof shall be on the defense to prove by a
preponderance of the evidence that the defendant is a person with an
intellectual disability. The jury shall return a verdict that either
the defendant is a person with an intellectual disability or the
defendant does not have an intellectual disability. The verdict of
the jury shall be unanimous. In any case in which the jury has been
unable to reach a unanimous verdict that the defendant is a person
with an intellectual disability, and does not reach a unanimous
verdict that the defendant does not have an intellectual disability,
the court shall dismiss the jury and order a new jury impaneled to
try the issue of intellectual disability. The issue of guilt shall
not be tried by the new jury.
(c) In the event the hearing is conducted before the court prior
to the commencement of the trial, the following shall apply:
(1) If the court finds that the defendant is a person with an
intellectual disability, the court shall preclude the death penalty
and the criminal trial thereafter shall proceed as in any other case
in which a sentence of death is not sought by the prosecution. If the
defendant is found guilty of murder in the first degree, with a
finding that one or more of the special circumstances enumerated in
Section 190.2 are true, the court shall sentence the defendant to
confinement in the state prison for life without the possibility of
parole. The jury shall not be informed of the prior proceedings or
the findings concerning the defendant's claim of intellectual
disability.
(2) If the court finds that the defendant does not have an
intellectual disability, the trial court shall proceed as in any
other case in which a sentence of death is sought by the prosecution.
The jury shall not be informed of the prior proceedings or the
findings concerning the defendant's claim of intellectual disability.
(d) In the event the hearing is conducted before the jury after
the defendant is found guilty with a finding that one or more of the
special circumstances enumerated in Section 190.2 are true, the
following shall apply:
(1) If the jury finds that the defendant is a person with an
intellectual disability, the court shall preclude the death penalty
and shall sentence the defendant to confinement in the state prison
for life without the possibility of parole.
(2) If the jury finds that the defendant does not have an
intellectual disability, the trial shall proceed as in any other case
in which a sentence of death is sought by the prosecution.
(e) In any case in which the defendant has not requested a court
hearing as provided in subdivision (b), and has entered a plea of not
guilty by reason of insanity under Sections 190.4 and 1026, the
hearing on intellectual disability shall occur at the conclusion of
the sanity trial if the defendant is found sane.
