Yesterday, the U.S. Supreme Court in Bullcoming v. New Mexico ruled that it violates the Confrontation Clause of the Sixth Amendment to permit a forensic report to be introduced at trial by putting on the stand a crime lab analyst who did not do the actual work in the case. The Court, in a majority opinion authored by Justice Ginsburg, reinforced the Court’s 2009 decision in Melendez-Diaz v. Massachusetts, by ruling that putting on such “surrogate testimony” denies the defense an opportunity for cross-examination. Some labs have long put on the stand forensic analysts who were not involved in the particular work done in a person’s case. Perhaps the analyst who actually did the work had left the office. Perhaps that analyst was overworked.  Or perhaps one analyst in the lab was especially effective in front of a jury.
