People v. Earpgreen

2 sentences

2025(People v. Earp (1999) 20 Cal.4th 826, 887 (Earp) [so holding].) Sandoval also resists this conclusion, asserting (1) that the failure to give a third-party culpability instruction implicates a 31 panoply of federal constitutional rights, such that we must presume prejudice unless the People establish the absence of the instruction was harmless beyond a reasonable doubt under Chapman v. California (1967) 386 U.S. 18, 24 , and (2) that this demanding standard cannot be met because the evidence of Alicia’s guilt was substantial.

2025(Earp, supra, 20 Cal.4th at p. 887 .) Its second step is also incorrect, as it is not reasonably probable that giving a third- party culpability instruction would have caused the jury to come to a different conclusion because, as noted above, the jury was elsewhere instructed that it could not convict any defendant unless each defendant’s guilt was established by the People beyond a reasonable doubt.

People v. Hartschgreen

2025(People v. Hartsch (2010) 49 Cal.4th 472, 500, 504 (Hartsch); People v. Harris (2013) 57 Cal.4th 804, 853 (Harris).) The trial court’s refusal to give the third-party culpability instruction Sandoval requested does not constitute error because the proffered instruction is both duplicative and confusing.

2025There was no prejudice As our Supreme Court has repeatedly held, a trial court’s failure to give a third-party culpability instruction is almost never prejudicial “because the [pattern] reasonable doubt instructions give defendants ample opportunity to impress upon the jury that evidence of another party’s liability must be considered in weighing whether the prosecution has met its burden of proof.” (Hartsch, supra, 49 Cal.4th at p. 504 ; People v.

2023The closing arguments focused the jury’s attention on that point.” (People v. Hartsch, supra, 49 Cal.4th at p. 504 ; see People v. Fayed (2020) 9 Cal.5th 147 , 176–178 [even where parties stipulate to the admissibility of third party culpability evidence, the failure to instruct on third party culpability was not prejudicial when jury was instructed on reasonable doubt].) In People v. Gutierrez (2009) 45 Cal.4th 789 , 824–825, the Supreme Court concluded a third party culpability instruction was not necessary when the jury was 10 properly instructed on the presumption of innocence and the gove

2021Because a third party culpability instruction is a “pinpoint” instruction that a court need not give unless requested (People v. Gutierrez (2009) 45 Cal.4th 789, 824 (Gutierrez)), and because defendant’s withdrawal negated her earlier request, defendant forfeited her right to raise this issue on appeal.

2023The trial court declined to give a third-party culpability instruction, citing People v.

2025Its first step is incorrect, as our Supreme Court has held that the failure to give a third-party culpability instruction is evaluated under People v. Watson (1956) 46 Cal.2d 818—not under Chapman.

2013Cruz maintains the court's ruling violated his rights under the state and federal Constitutions to present a third party culpability defense and to confront the witnesses against him; he adds the error is not harmless under either the more stringent beyond-a-reasonable-doubt prejudice standard of Chapman v. California (1967) 386 U.S. 18, 24 (Chapman) or the state law standard of People v. Watson (1956) 46 Cal.2d 818, 836 (Watson).

Nor was an instruction needed to correct any misstatement by counsel in closing arguments.

Statutes the citing opinions construe

CA § Cal. Penal Code § 187 (12) CA § Cal. Evidence Code § 1200 (8) CA § Cal. Evidence Code § 352 (7) CA § Cal. Evidence Code § 1101 (6) CA § Cal. Evidence Code § 1108 (3) CA § Cal. Evidence Code § 1235 (3) CA § Cal. Evidence Code § 1240 (3) CA § Cal. Evidence Code § 210 (3)

Counted by distinct opinions that both name this issue and are annotated to the section; sections every opinion cites regardless of issue are not filtered here, so read the counts against the total above.

Where else courts name it

CA 31 (2003–2026) CT 30 (1992–2025) AZ 14 (2011–2025) NY 14 (2009–2026)

Opinions by the citing court's state. A doctrine retained in one state and abandoned in another shows up here as a year span that stalls.
