Can a defendant appeal against his conviction for sexual assault against the evidence that supports his conviction?

Defendant offers alternative and innocuous explanations of the evidence that supports his conviction. Under the substantial evidence rule, however, " 'if the circumstances reasonably justify the jury's findings, the judgment may not be reversed simply because the circumstances might also reasonably be reconciled with a contrary finding.' [Citation.] Accordingly, we need not and do not address all of defendant['s] assertions of conflict[] in the evidence, or [his] alternative theories regarding the inference[] that should have been drawn from the evidence." (People v. Letner and Tobin (2010) 50 Cal.4th 99, 162.)
