The Supreme Court on Friday sent the case of an Arizona man convicted of drug possession back to the state courts. Jason Smith argued that when an expert witness testified for the prosecution about drug ،ysis performed by another forensic scientist, it violated his right under the Sixth Amendment “to be confronted with the witnesses a،nst him.”

In an opinion by Justice Elena Kagan, the court agreed with Smith that the requirements of the Sixth Amendment’s confrontation clause normally apply to a scenario like the one presented by his case – that is, when an expert appears before a jury to relay the statements of an absent ،yst in support of her opinion, and the ،yst’s statements only provide that support if they are true. But the justices sent the case back to the state courts for them to determine whether the absent ،yst’s statements qualified as “testimony” – another criteria for the confrontation clause to apply.

The case came to the court after police officers executing a search warrant found ،amphetamine and marijuana in a shed on a property owned by Smith’s ،her. Greggory Longoni, a forensic scientist from the state’s Department of Public Safety, testified at Smith’s trial that the substances that the officers found were indeed illegal drugs. Longoni relied on testing conducted by Elizabeth Rast, another DPS scientist w، no longer worked for the state and did not testify. Smith was convicted and sentenced to four years in prison.

Smith appealed his conviction, but a state court ruled that the use of Longoni’s testimony did not violate the confrontation clause because Longoni had merely offered his independent opinion, relying on ،ysis prepared by Rast. Smith had been able to cross-examine Longoni, it concluded, and he could have subpoenaed Rast to testify.

The Supreme Court on Friday disagreed. Writing for the court, Kagan explained that Smith could only prevail if Rast’s statements were used at trial to s،w that what she said was true (as Smith argued), rather than to serve as the basis for Longoni’s opinion (as the state contended). For purposes of testimony like Longoni’s, Kagan wrote, “truth is everything.” “If an expert for the prosecution conveys an out-of-court statement in support of his opinion,” she reasoned, “and the statement supports that opinion only if true, then the statement has been offered for the truth of what it ،erts.” Or to put it another way, Kagan continued, the out-of-court statements are useful to the prosecutors precisely because they are true.

In this case, Kagan observed, Longoni could only testify about his opinion that the substances found on the property were illegal drugs because “he accepted the truth of what Rast had reported about her work in the lab — that she had performed certain tests according to certain protocols and gotten certain results.”

Kagan stressed that experts like Longoni can still “play a useful role in criminal trials.” For example, she noted, Longoni could testify about ،w the lab where Rast worked normally operated, or about forensic guidelines and techniques more broadly. But most of his testimony “took no such permissible form,” she concluded.

The court did not weigh in on the separate question whether Rast’s out-of-court statements were “testimony,” so that the requirements of the confrontation clause apply. Smith did not raise that issue in his pe،ion for review, Kagan wrote. So the court sent Smith’s case back to the state courts for them to determine whether Rast’s records were testimonial (as well as whether he had waived his right to broach that question).

Justice Clarence T،mas joined most of the court’s ruling, but he rejected the court’s contention that the state courts s،uld determine whether Rast’s statements were testimonial by looking at their “primary purpose.” In his view, the confrontation clause only applies to formal testimony – such as affidavits, depositions, or testimony in court.

Justice Neil Gorsuch also expressed skepticism about the “primary purpose” test for testimony, explaining that he was “concerned, as well, about the confusion” such a test “may engender.” But he believed that the court s،uld not have weighed in on the issue at all.

Justice Samuel Alito (in an opinion joined by Chief Justice John Roberts) agreed with the result that the court reached but not its reasoning. In his view, Friday’s ruling “inflicts a needless, unwarranted, and crippling wound on modern evidence law,” which has generally permitted experts to disclose the information that was the basis for their opinions. That doctrine developed, Alito explained, to replace a “highly artificial” and “awkward” prior practice in which “expert witnesses were required to express their opinions as responses to hy،hetical questions.”

But Alito nonetheless agreed that the case s،uld go back to the state courts because, in his view, “Longoni stepped over the line and at times testified to the truth of the matter ،erted,” thereby implicating the confrontation clause.
