EVEN WHERE EVIDENCE OF AN UNCHARGED CRIME IS “INEXTRICABLY INTERTWINED” WITH THE NARRATIVE OF CHARGED CRIME, IT MAY BE INADMISSIBLE BECAUSE ITS PREJUDICIAL EFFECT OUTWEIGHS ITS PROBATIVE VALUE; HERE THE COMPLAINANT’S TESTIMONY ABOUT A PRIOR UNCHARGED SEX ACT SHOULD NOT HAVE BEEN ADMITTED (FIRST DEPT).

The Frist Department, reversing the conviction in this sexual abuse prosecution, determined the evidence of a prior sex act with the complainant was much more prejudicial than probative. The evidence was therefore inadmissible:

Prior to the commencement of jury selection for the second trial, the People made a Molineux application to allow the complainant to testify about an alleged prior oral sexual encounter with defendant. The People argued, inter alia, that this evidence was “inextricably intertwined” with the complainant’s testimony as to the charges of sexual abuse, provided relevant background, and put the complainant’s testimony “into a believable context.” Supreme Court granted the People’s motion. The court concluded that the proposed testimony was “inextricably woven [in]to the narrative.” …

Supreme Court erred in granting the People’s Molineux application. Even if the People established some non-propensity basis for introducing this evidence, “the prejudicial nature of that evidence far outweighed any probative value” … . People v Nieves, 2026 NY Slip Op 00979, First Dept 2-19-26

Practice Point: Here in this sexual abuse prosecution, the complainant’s testimony about a prior, uncharged sex act was deemed much more prejudicial than probative. Therefore the testimony was inadmissible, despite the argument that it was “inextricably intertwined” with the narrative of the crime or provided relevant background.
