In D.Z. v. Los Angeles Unified School Dist., published May 14, 2019, the Second District Court of Appeal, Division 4, reversed a jury verdict in favor of the defendant district. The plaintiff high school student alleged that a teacher inappropriately touched her, that school administrators knew or should have known of the danger posed by the teacher, and that the district's failure to respond appropriately to that knowledge caused her harm. In response to a motion in limine under Evidence Code section 352, the trial court excluded all evidence of alleged misconduct by the teacher apart from inappropriate touching of students. The evidence excluded included a risque joke about a student's chest that resulted in an investigation of the teacher. It also included the teacher showing favoritism to female students and offering students rides home. The trial court also gave, over the plaintiff's objection, jury instructions directing the jury to determine whether the school principal was a district employee and whether the principal acted within the scope of her duties when she harmed the plaintiff.
The appellate court ruled that the trial court abused its discretion by abusing the evidence as irrelevant. Evidence of alleged misconduct other than the improper touching was relevant to whether the district had notice that the teacher's conduct was reasonably foreseeable, which must be determined under all of the circumstances. While some of the evidence might not have been relevant, the line the court drew barring all non-touching evidence was improper. The appellate court noted that trial courts may exclude relevant evidence as inflammatory. The trial court, however, never reached that issue. The appellate court ruled the exclusion prejudicial, particularly since the defense counsel used the exclusion to minimize evidence of the teacher's conduct before the alleged touching occurred. The appellate court further ruled that the jury instructions concerning the principal's employment and scope of duties were improper. Since the principal's employment and scope of duties were undisputed, the instructions served only to confuse the jury.
