I recently gave a criminal law case update to a group of judges. I had quite a few cases that I planned to cover in relatively short order. I started with Smith v. Arizona, 602 U.S. 779 (2024), in which the United States Supreme Court held that statements from an absent laboratory analyst that a testifying analyst conveyed to support his expert opinion about the chemical composition of the substances seized from the defendant were hearsay. For that reason, their admission at the defendant’s trial on drug charges raised Confrontation Clause concerns. To my chagrin, twenty minutes later, I was still talking about Smith, attempting to helpfully respond to a barrage of questions from trial court judges about the practical import of the decision for various kinds of testimony frequently proffered by the State during a criminal trial. Those questions included the following:
- The substitute analysts I see don’t typically rely on another analyst’s report. Instead, they examine the underlying testing data and reach an opinion based on that. Is that testimony admissible?
- May a supervising analyst who reviewed the testing done by and conclusions of another analyst pursuant to laboratory protocols testify to the conclusions the supervising analyst reached about the identity of the substance?
- Suppose a new analyst retests a substance. Will he or she be able to establish a sufficient chain of custody for the substance tested given that the substance was initially received and examined by an analyst who is not available to testify?
This post will review what we knew about substitute analyst testimony before Smith was decided, will recap the Court’s analysis in Smith (analyzed in detail here), and will provide some thoughts about Smith’s import that may inform a court’s analysis of the questions posed above.
