California Penal Code. California
activity by the defendant which did not involve the use or attempted use of force or violence or which did not involve the express or implied threat to use force or violence. As used in this section, criminal activity does not require a conviction.
However, in no event shall evidence of prior criminal activity be admitted for an offense for which the defendant was prosecuted and acquitted. The restriction on the use of this evidence is intended to apply only to proceedings pursuant to this section and is not intended to affect statutory or decisional law allowing such evidence to be used in any other proceedings.
Except for evidence in proof of the offense or the prior prison term for murder of the first or second degree which subjects a defendant to the punishment of life without the possibility of parole, no evidence may be presented by the prosecution in aggravation unless notice of the evidence to be introduced has been given to the defendant within a reasonable period of time as determined by the court, prior to trial. Evidence may be introduced without such notice in rebuttal to evidence introduced by the defendant in mitigation.
In determining the penalty, the trier of fact shall take into account any of the following factors if relevant:
(1) The circumstances of the crime of which the defendant was convicted in the present proceeding and the existence of the prior prison term for murder.
(2) The presence or absence of criminal activity by the defendant which involved the use or attempted use of force or violence or the express or implied threat to use force or violence.
(3) The presence or absence of any prior felony conviction.
(4) Whether or not the offense was committed while the defendant was under the influence of extreme mental or emotional disturbance.
(5) Whether or not the victim was a participant in the defendant’s homicidal conduct or consented to the homicidal act.
(6) Whether or not the offense was committed under circumstances which the defendant reasonably believed to be a moral justification or extenuation for his or her conduct.
(7) Whether or not the defendant acted under extreme duress or under the substantial domination of another person.
(8) Whether or not at the time of the offense the ability of the defendant to appreciate the criminality of his or her conduct or to conform his or her conduct to the requirements of law was impaired as a result of mental disease or defect, or the effects of intoxication.
(9) The age of the defendant at the time of the crime.
(10) Whether or not the defendant was an accomplice to the offense and his or her participation in the commission of the offense was relatively minor.
(11) Any other circumstance which extenuates the gravity of the crime even though it is not a legal excuse for the crime.
After having heard and received all of the evidence, and after having heard and considered the arguments of counsel, the trier of fact shall consider, take into account, and be guided by the aggravating and mitigating circumstances referred to in this section, and shall impose a sentence of life without the possibility of parole if the trier of fact concludes that the aggravating circumstances outweigh the mitigating circumstances. If the trier of fact determines that the mitigating circumstances outweigh the aggravating circumstances, the trier of fact shall impose a sentence of confinement in the state prison for 15 years to life.
(i) Nothing in this section shall be construed to prohibit the charging of finding of any special circumstance pursuant to Sections 190.1, 190.2, 190.3, 190.4, and 190.5.
(Added by Stats. 1985, Ch. 1510, Sec. 1.)
190.1.
A case in which the death penalty may be imposed pursuant to this chapter shall be tried in separate phases as follows:
(a) The question of the defendant’s guilt shall be first determined. If the trier of fact finds the defendant guilty of first degree murder, it shall at the same time determine the truth of all special circumstances charged as enumerated in Section 190.2 except for a special circumstance charged pursuant to paragraph (2) of subdivision (a) of Section 190.2 where it is alleged that the defendant had been convicted in a prior proceeding of the offense of murder in the first or second degree.
(b) If the defendant is found guilty of first degree murder and one of the special circumstances is charged pursuant to paragraph (2) of subdivision (a) of Section 190.2 which charges that the defendant had been convicted in a prior proceeding of the offense of murder of the first or second degree, there shall thereupon be further proceedings on the question of the truth of such special circumstance.
(c) If the defendant is found guilty of first degree murder and one or more special circumstances as enumerated in Section 190.2 has been charged and found to be true, his sanity on any plea of not guilty by reason of insanity under Section 1026 shall be determined as provided in Section 190.4. If he is found to be sane, there shall thereupon be further proceedings on the question of the penalty to be imposed. Such proceedings shall be conducted in accordance with the provisions of Section 190.3 and 190.4.
