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

Fleming also argues that admitting the evidence in question violated his due process rights. "'Ordinarily, even erroneous admission of evidence does not offend due process unless it is so prejudicial as to render the proceeding fundamentally unfair.' ... [] 'To prove a deprivation of federal due process rights, [a defendant] must satisfy a high constitutional standard to show that the erroneous admission of evidence resulted in an unfair trial.' [Citation.] '"The dispositive issue is ... whether the trial court committed an error which rendered the trial 'so "arbitrary and fundamentally unfair" that it violated federal due process.' [Citations.]" [Citation.]' [Citation.]" (People v. Covarrubias (2011) 202 Cal.App.4th 1, 20.)
