2023(People v. Young (2005) 34 Cal.4th 1149, 1217 .) “A trial court’s decision whether or not to hold a competence hearing is entitled to deference, because the court has the opportunity to observe the defendant during trial.” (People v. Rogers (2006) 39 Cal.4th 826, 847 .) An appellate court is generally not in a position to appraise a defendant’s conduct in the trial court as indicating insanity, a calculated attempt to feign insanity and delay the proceedings, or sheer temper.

2021A trial court reversibly errs if it fails to hold a competency hearing when one is required under the substantial evidence test.’ ” (People v. Woodruff, supra, 5 Cal.5th at p. 721 ; see People v.

[Citation.] In that event, the trial judge has no discretion to exercise.

2025Indeed, counsel acts “irresponsibly” if he or she leaves “to defendant the task of deciding which information the psychiatrists should review in preparation for the competence hearing.” (People v. Samuel (1981) 29 Cal.3d 489, 496 .) Courts have therefore held that defense counsel may furnish an illegally obtained confession to an expert evaluator “who considers that confession in forming an opinion of the defendant’s mental condition.” (Id. at p. 495.) And when, as here, defense counsel has only provided information to the expert evaluator that is “ ‘directly relevant to’ the competency evalua

1994Rather, “the trial court obviously ordered a competence hearing in an overabundance of caution, and not because it was statutorily or constitutionally compelled to do so.” {Id. at p. 184.) Now that the issue is squarely presented, we conclude, as we did implicitly in People v. McPeters, supra, 2 Cal.4th at pages 1168-1169, that the presumption of competence upheld in People v. Medina, supra, 51 Cal.3d 870 , does not affect the continuing validity of People v. Samuel, supra, 29 Cal.3d 489 , or People v. Hill, supra, 67 Cal.2d 105 .

2025When a court doubts a defendant’s competence to stand trial, it ‘shall appoint a psychiatrist or licensed psychologist, and any other expert the court may deem appropriate, to examine the defendant.’ [Citation.] Similarly, when it doubts the defendant’s mental competence for self-representation, it may order a psychological or psychiatric examination to inquire into that question.” (Johnson, supra, 53 Cal.4th at p. 530 .) The court should apply the heightened competence standard “cautiously.” (Id. at p. 531.) “Criminal defendants still 7 generally have a Sixth Amendment right to represent them
