Defendants can lose confrontation rights a number of ways. Under the various notice and demand statutes, failure to object and demand the presence of the witness in a timely manner following receipt of the State’s notice results in waiver of the right to personally confront the witness. See, e.g., G.S. 90-95(g); G.S. 20-139.1(e1) (among others). A defendant can also forfeit his or her right to confrontation by wrongdoing—where the State can prove that the defendant’s conduct resulted in the unavailability of a witness, the defendant loses the right to confront that witness. Giles v. California, 554 U.S. 353 (2005). Stipulations to the admissibility of evidence, the subject of today’s post, are another form of waiver. When the defendant stipulates to a lab result, the right to personally confront the analyst is lost. What process is due before the judge accepts such a stipulation? Is the stipulation itself sufficient to waive confrontation rights? Or should the trial judge personally engage the defendant to ensure the waiver of confrontation rights is knowing and voluntary before accepting the stipulation? The Court of Appeals answered that question in a recent case.
