What is the test for substantial evidence in a civil case?

The majority correctly states the well-settled substantial evidence rule. We review the sufficiency of the evidence supporting the jury's retaliation verdict under the substantial evidence standard. Under that standard, we "view the evidence in the light most favorable to the prevailing party, giving it the benefit of every reasonable inference and resolving all conflicts in its favor." (Bickel v. City of Piedmont (1997) 16 Cal.4th 1040, 1053.) Our task "begins and ends with the determination as to whether, on the entire record, there is substantial evidence, contradicted or uncontradicted," which will support the verdict. (Bowers v. Bernards (1984) 150 Cal.App.3d 870, 873-874.)

Substantial evidence is any evidence that is "reasonable in nature, credible, and of solid value." (People v. Bassett (1968) 69 Cal.2d 122, 139.) Testimony from a single witness may suffice. (In re Marriage of Mix (1975) 14 Cal.3d 604, 614.)

In other words, our inquiry on substantial evidence review is whether the evidence adds up to substantial evidence supporting the judgment. (People v. Jackson (2014) 58 Cal.4th 724, 749.) Here it unquestionably does.
