What is the test for overturning a finding that the testimony of John Doe witnesses was credible?

Plaintiffs also challenge the trial court's determination that the testimony of the John Doe witnesses was credible. A reviewing court does not reweigh the evidence or reconsider credibility determinations. (Katsura v. City of San Buenaventura (2007) 155 Cal.App.4th 104, 107.) It was within the exclusive province of the trial court, as the trier of fact, to determine credibility. (Sabbah v. Sabbah (2007) 151 Cal.App.4th 818, 823.) "[T]he testimony of a witness whom the trier of fact believes, whether contradicted or uncontradicted, is substantial evidence, and we must defer to the trial court's determination that these witnesses were credible. [Citations.]" (Estate of Odian (2006) 145 Cal.App.4th 152, 168.)

Plaintiffs' attempts to reargue selected portions of the evidence in an effort to induce this court to make different findings is not a valid ground for overturning the trial court's order. On substantial evidence the trial court found that plaintiffs and their counsel committed a fraud on the court by presenting false evidence and testimony. A reviewing court is powerless to modify such findings. (Sketchley v. Lipkin (1950) 99
