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 evidencethat is, evidence which is reasonable, credible, and of solid valuesuch that a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.' [Citations.]" (People v. Ceja (1993) 4 Cal.4th 1134, 1138.)
