Is a defendant entitled to an evidentiary hearing to resolve factual disputes raised by a claim of juror misconduct?

"The trial court has discretion to determine whether to conduct an evidentiary hearing to resolve factual disputes raised by a claim of juror misconduct. [Citation.] 'Defendant is not, however, entitled to an evidentiary hearing as a matter of right. Such a hearing should be held only when the court concludes an evidentiary hearing is "necessary to resolve material, disputed issues of fact." [Citation.]'" (People v. Dykes, supra, 46 Cal.4th at p. 809.) "The trial court's decision whether to conduct an evidentiary hearing on the issue of juror misconduct will be reversed only if the defendant can demonstrate an abuse of discretion. [Citations.]" (Id. at p. 810.)
