What is the test for questioning the credibility of a law enforcement witness in a civil case?

From the above, the logical framework for analysis of the issue is clear. First, counsel must present a good faith basis for inquiring, namely, the lawsuit relied upon; second, specific allegations that are relevant to the credibility of the law enforcement witness must be identified; and third, the trial judge exercises discretion in assessing whether inquiry into such allegations would confuse or mislead the jury, or create a substantial risk of undue prejudice to the parties (see Delaware v. Van Arsdall, 475 U.S. 673, 679, 106 S.Ct. 1431, 89 L.Ed.2d 674 [1986] ; see People v. Harrell, 209 A.D.2d 160, 160, 618 N.Y.S.2d 631 [1st Dept.1994] ).
