Bullcoming v. New Mexico, 564 U.S. 647 (2011), is a significant 6th Amendment Confrontation Clause case decided by the United States Supreme Court. On June 23, 2011, the Supreme Court considered the issue whether a defendant's Confrontation Clause rights extend to a non-testifying laboratory analyst whose supervisor testifies as to test results that the analyst transcribed from a machine. In a five to four decision authored by Justice Ginsburg, the Court held that the second surrogate analyst could not testify about the testimonial statements in the forensic report of the certifying analyst under the Confrontation Clause.
