What is the test to suppress evidence in a civil case?

"As the finder of fact in a proceeding to suppress evidence (Pen. Code, 1538.5), the superior court is vested with the power to judge the credibility of the witnesses, resolve any conflicts in the testimony, weigh the evidence and draw factual inferences in deciding whether a search is constitutionally unreasonable." (People v. Woods (1999) 21 Cal.4th 668, 673 (Woods).) On appeal, all factual conflicts must be resolved in the manner most favorable to the trial court's disposition. (Ibid.)
