What is the test for a motion to overturn a finding of insufficient sufficiency of evidence in a sexual assault case?

In reviewing a challenge to the sufficiency of the evidence, appellate courts do not determine the facts. We examine the record as a whole in the light most favorable to the judgment and presume the existence of every fact the trier of fact could reasonably deduce from the evidence in support of the judgment. (People v. Kraft (2000) 23 Cal.4th 978, 1053.) If the verdict is supported by substantial evidence, a reviewing court must accord due deference to the trier of fact and not substitute its evaluation of a witness's credibility for that of the fact finder. (People v. Ochoa (1993) 6 Cal.4th 1199, 1206.)

The testimony of a single witnessunless physically impossible or inherently improbableis sufficient for a conviction. (Evid. Code, 411; People v. Young (2005) 34 Cal.4th 1149, 1181.)

An appellate court must accept logical inferences the jury might have drawn from circumstantial evidence. (People v. Maury (2003) 30 Cal.4th 342, 396.) Before the judgment of the trial court can be set aside for insufficiency of the evidence, "it must clearly appear that on no hypothesis whatever is there sufficient substantial evidence to support the verdict of the jury." (People v. Hicks (1982) 128 Cal.App.3d 423, 429; see People v. Conners (2008) 168 Cal.App.4th 443, 453.)
