Smith v. Arizona

In Smith v. Arizona, petitioner Jason Smith was convicted in Arizona state court of drug-related offenses. At trial, a forensic analyst testified about drug identification, but the actual testing was performed by a different analyst who did not testify. Smith objected that this surrogate testimony violated his Sixth Amendment right to confront witnesses against him. The Arizona courts affirmed the conviction. The U.S. Supreme Court granted certiorari. In a unanimous decision authored by Justice Elena Kagan, the Court held that when an expert conveys an absent analyst's testimonial statements as true, the Confrontation Clause is violated unless the accused had a prior opportunity for cross-examination. The case was remanded for the state courts to apply this framework.

The U.S. Supreme Court vacated the Arizona court's judgment and remanded, holding that surrogate analyst testimony may violate the Sixth Amendment Confrontation Clause; the case was remanded for further proceedings consistent with the Court's opinion.

Whether the Confrontation Clause permits an expert witness to testify about another analyst's laboratory report without the defendant having an opportunity to cross-examine the analyst who performed the testing.

The decision reinforces defendants' confrontation rights in forensic and expert testimony, limits the use of surrogate experts as a substitute for live testimony by analysts who performed testing, and may require prosecutors to call original analysts or establish independent expert opinions.
