What is the effect of a motion denying a defendant's fourth motion in a personal injury case?

Defendant argues the trial court abused its discretion in denying his fourth motion made pursuant to People v. Marsden (1970) 2 Cal.3d 118 (Marsden) "because an irreconcilable conflict between [defendant] and his appointed attorney violated [defendant's] Sixth Amendment right to the effective assistance of counsel."
