Is there any case law where a defendant accused his appointed attorney of not wanting to defend him?

[118 Cal.App.3d 966] In People v. Munoz, supra, 41 Cal.App.3d 62, 115 Cal.Rptr. 726, the defendant accused his appointed attorney of not wanting to defend him; he alleged that the attorney told him he was guilty and did not have a 'chance.' (41 Cal.App.3d at p. 66, 115 Cal.Rptr. 726.) Viewing these allegations as tantamount to charging that counsel was not committed to providing an effective defense, the court held that the trial court erred in denying defendant's request for substitution of attorneys without inquiry into the court-appointed attorney's state of mind. (Ibid. Accord People v. Cruz (1978) 83 Cal.App.3d 308, 316-318, 115 Cal.Rptr. 726.)
