EXPERT EVIDENCE ABOUT THE EFFECT OF A DRUG MIXED WITH ALCOHOL ON DEFENDANT’S ABILITY TO FORM THE INTENT TO COMMIT MURDER AND ASSAULT SHOULD HAVE BEEN ADMITTED; DEFENDANT SHOULD HAVE BEEN ALLOWED TO LAY A FOUNDATION TO QUALIFY AN EMAIL WHICH INCLUDED HEARSAY AS A BUSINESS RECORD; NEW TRIAL ORDERED.

The Third Department, reversing defendant’s attempted murder and assault convictions, determined expert testimony explaining the effects of a drug taken by the defendant along with alcohol should have been admitted. In addition, an email in which a police officer, who was not at the scene, referred to the defendant’s condition as “highly intoxicated” should not have been excluded as hearsay. If the document had been qualified as a business record, it would have been admissible. The defendant should have been given an opportunity to establish a foundation for the admissibility of the email:

As a general rule, the admissibility and limits of expert testimony lie primarily in the sound discretion of the trial court” … . The criteria to be used is “whether the proffered expert testimony ‘would aid a lay jury in reaching a verdict’ ” … , however, and the testimony proffered here regarding the effect of combined clonazepam and alcohol use would undoubtedly be useful to a lay jury in assessing “the ability of a defendant to form the intent to commit a crime following drug and alcohol consumption” … . As the Court of Appeals explained when presented with a comparable situation, while “jurors might be familiar with the effects of alcohol on one’s mental state, the combined impact of” alcohol and other drugs “on a person’s ability to act purposefully cannot be said as a matter of law to be within the ken of the typical juror” … . * * *

County Court erred in refusing to allow defendant to question the author of the preliminary investigation report describing defendant as “highly intoxicated” and then declining to admit the document into evidence on hearsay grounds because its author was not present on the night of the incident. Defendant must be afforded an opportunity to establish the proper foundation to qualify the email as a business record within the meaning of CPLR 4518 and, if defendant is successful in that effort, the fact that its author lacked personal knowledge of defendant’s intoxication goes to the weight, not the admissibility, of the statements therein … . People v Mawhiney, 2023 NY Slip Op 05289, Third Dept 10-19-23

Practice Point: Where an issue is beyond the ken of an average juror, here the effect of a drug and alcohol combination on the defendant’s ability to form intent, expert testimony should be admitted.

Practice Point: Here an email by a police officer who was not at the scene of the shooting referred to the defendant as “highly intoxicated.” Although the statement is hearsay, the email may be admissible if it is demonstrated to be a business record.
