In New York, the prosecution in a criminal case is generally unable to present evidence of a defendant’s prior crimes or bad acts. There are, however, exceptions to this rule, and courts can admit otherwise inadmissible evidence using one of the exceptions laid out in the rules of evidence. As a general rule, evidence of a prior bad act may never be used to demonstrate that a person has a propensity for committing crimes.
The Exceptions
The five exceptions to the rule that evidence of a defendant’s prior crime is inadmissible are when the evidence helps establish a defendant’s (1) intent or purpose, (2) motive, (3) knowledge, (4) plan, or (5) identity. These five categories can all end up being fairly broad, and each trial court might interpret the exceptions a bit differently. This can, in turn, be challenging for defendants who are trying to keep evidence of prior bad acts out of the record to keep the jury from being prejudiced against them.
In a recent case before the Appellate Division, Second Department, the defendant challenged the trial court’s use of exception #1, intent or purpose. During the defendant’s trial for criminal contempt in the first degree and aggravated harassment in the second degree, the prosecution sought to present evidence of testimony about an incident that let to a protective order against the defendant. Allegedly, the defendant had violated that protective order, which brought him to court on the criminal contempt and aggravated harassment charges.
