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

The trial court retains discretion to admit or exclude relevant evidence offered. (People v. Rodriguez (1999) 20 Cal.4th 1, 9; Evid. Code, 352.) A trial court's exercise of such discretion in admitting or excluding evidence "is reviewable for abuse [citation] and will not be disturbed except on a showing the trial court exercised its discretion in an arbitrary, capricious, or patently absurd manner that resulted in a manifest miscarriage of justice." (Rodriguez, supra, at pp. 9-10.)
