What is the test for determining whether there was sufficient evidence at the renewal hearing of a motion alleging that respondent harassed appellants?

In a judgment roll appeal, "[t]he sufficiency of the evidence is not open to review. The trial court's findings of fact and conclusions of law are presumed to be supported by substantial evidence and are binding on the appellate court, unless reversible error appears [on the face] of the record." (Bond v. Pulsar Video Productions (1996) 50 Cal.App.4th 918, 924.) Because we have no record of the oral proceedings at the renewal hearing, we must presume that sufficient evidence was presented at the hearing that appellants harassed respondent. (See Diamond View Limited v. Herz (1986) 180 Cal.App.3d 612, 615, fn. 2.)³
