What is the test for determining the sufficiency of the evidence to support the findings of an appellate court?

In determining the sufficiency of the evidence to support the findings an appellate court must " '... determine whether the evidence, viewed in the light most favorable to the respondent, sustains the findings subject to review, resolving any reasonable doubts in favor of those findings. [Citation.] In making this determination the appellate court must resolve all conflicts in the evidence in favor of the judgment or decision of the tribunal below and indulge in all legitimate and reasonable inferences to support it.' " (Greenebaum v. City of Los Angeles (1984) 153 Cal.App.3d 391, 408, 200 Cal.Rptr. 237.)
