THE EXPERTS WHO TESTIFIED THE SEIZED SUBSTANCES CONTAINED HEROIN OR COCAINE RELIED ON COMPARISONS WITH STANDARD SAMPLES IN THEIR LABS BUT NO EVIDENCE WAS OFFERED TO DEMONSTRATE THE ACCURACY OF THE SAMPLES; THEREFORE THE EXPERTS’ OPINIONS RELIED ON EVIDENCE NOT IN THE RECORD; CONVICTIONS REVERSED (SECOND DEPT).

The Second Department, reversing the convictions which relied on expert evidence that the seized substances contained cocaine or heroin, determined the experts relied on evidence which was not in the record. Therefore a proper foundation had not been laid for the conclusions that the substances contained cocaine and heroin:

Here, each of the People’s five experts testified to arriving at the conclusion that the substance tested was either heroin or cocaine by comparing the substance with a standard sample in the laboratory that was known to be heroin or cocaine. When questioned about the accuracy of the known standard, the experts testified generally that the sample reference material was obtained from chemical manufacturers. Some of the experts testified that the samples came with certifications, which might have established the sample’s accuracy, but no such certifications were offered into evidence. Some of the experts testified that the sample reference material generally is tested upon arrival at the laboratory, but none of the experts could testify to personal knowledge of the testing of the known standard that she or he used in this case, and the People did not introduce any evidence establishing that such independent testing had occurred. …

Although an expert’s testimony that a substance contains a narcotic drug may be admissible when it is not based solely upon comparative tests using known standards, but is also based on other tests not involving known standards, or other facts in evidence … , here, two of the experts relied solely upon the comparative tests, and their testimony should have been stricken …. Further, while the other three experts testified that before using the comparative tests to confirm the identity of the substance, she or he employed one or more presumptive tests, each of those presumptive tests merely demonstrated the possibility that cocaine or heroin might be present in the substance, but did not confirm the presence of the narcotic drug. It was the comparison to the known standard that enabled each expert to conclude that the substance tested was heroin or cocaine … . People v Ramis, 2023 NY Slip Op 01013, Second Dept 2-22-23

Practice Point: If an expert’s opinion relies on information that is not in the record, a proper foundation for the opinion has not been laid. Here the experts’ opinions that seized substances contained cocaine and heroin were based on comparison with samples in the lab, but no evidence demonstrating the accuracy of the samples was presented.
