The Fourth Department reversed defendant’s conviction finding that summary exhibits were improperly admitted in evidence under the “voluminous writings” exception to the best evidence rule. In addition, the court determined defense counsel was ineffective for failure to review the summary exhibits and object to their admission:

We conclude that the summary exhibits were improperly admitted under the voluminous writings exception to the best evidence rule inasmuch as defendant was not provided with the data underlying those exhibits prior to trial …nor were those exhibits based solely upon information already in evidence … . Defendant was thus denied “a full and fair opportunity” to challenge the accuracy of the summary exhibits… . People v Case, 1310, 4th Dept 2-14-14
