What role does the Court of Appeal have in determining the sufficiency of evidence in a sexual assault case?

"The role of an appellate court in reviewing the sufficiency of the evidence is limited. The court must 'review the whole record in the light most favorable to the judgment below to determine whether it discloses substantial evidence that is, evidence which is reasonable, credible, and of solid value such that a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.' [Citations.] []... But it is the jury, not the appellate court, which must be convinced of the defendant's guilt beyond a reasonable doubt. [Citation.] Therefore, an appellate court may not substitute its judgment for that of the jury." (People v. Ceja, supra, 4 Cal.4th at pp. 1138-1139.)
