What is the standard of review of the sufficiency of evidence in a sexual assault case?

The principles governing our review of the sufficiency of the evidence are well settled. "We ' "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.] We presume ' "in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence." [Citation.] This standard applies whether direct or circumstantial evidence is involved.' [Citation.]" (People v. Prince (2007) 40 Cal.4th 1179, 1251.) " 'Substantial evidence includes circumstantial evidence and any reasonable inferences drawn from that evidence.' [Citation.]" (People v. Brooks (2017) 3 Cal.5th 1, 57.)

" 'Conflicts and even testimony [that] is subject to justifiable suspicion do not justify the reversal of a judgment, for it is the exclusive province of the trial judge or jury to determine the credibility of a witness and the truth or falsity of the facts upon which a determination depends. [Citation.] We resolve neither credibility issues nor evidentiary conflicts; we look for substantial evidence. [Citation.]' [Citation.] A reversal for insufficient evidence 'is unwarranted unless it appears "that upon no hypothesis whatever is there sufficient substantial evidence to support" ' the jury's verdict. [Citation.]" (People v. Zamudio (2008) 43 Cal.4th 327, 357.)

"The standard of review is the same in cases in which the People rely mainly on circumstantial evidence. [Citation.] 'Although it is the duty of the jury to acquit a defendant if it finds that circumstantial evidence is susceptible of two interpretations, one of which suggests guilt and the other innocence [citations], it is the jury, not the appellate court which must be convinced of the defendant's guilt beyond a reasonable doubt. " 'If the circumstances reasonably justify the trier of fact's findings, the opinion of the reviewing court that the circumstances might also reasonably be reconciled with a contrary finding does not warrant a reversal of the judgment.' " [Citations.]' [Citation.]" (People v. Stanley (1995) 10 Cal.4th 764, 792-793.)

"The choice of which inference is to be drawn from the facts, where more than one reasonable inference is possible, is the function of the jury. [Citation.] 'It is not the province of the reviewing court to overturn the jury's verdict when it is supported by substantial evidence including the reasonable inferences to be drawn therefrom.' [Citation.]" (People v. Sweeney (1960) 55 Cal.2d 27, 51.) Moreover, "unless the testimony is physically impossible or inherently improbable, testimony of a single witness is sufficient to support a conviction. [Citation.]" (People v. Young (2005) 34 Cal.4th 1149, 1181.)
