United States v. Holmes
9th Circuit Court of Appeals; Case No. 22-10312
Argument(s)
The Federal Rules of Criminal Procedure and of Evidence work together to ensure that a criminal defendant can confront and challenge an expert witness proffered by the prosecution. Rule 16 requires the prosecution to timely disclose the identity of an expert witness, and the basis for that expert’s testimony, sufficiently before trial to permit a criminal defendant to mount a complete defense. And the rules of evidence—in particular, Rules 701 and 702—ensure that an expert’s testimony is based on reliable, verifiable data that can be the subject of rigorous cross-examination. In this prosecution, the defendant, Elizabeth Holmes, was robbed of the protections of these rules. The government disclosed a lay-turned-expert witness—on the critical question of whether Theranos technology worked— on the eve of trial, years after the Rule 16 deadline had passed. Worse, that expert testimony relied upon data that no longer existed, meaning it was neither reliable nor verifiable, and could not be the subject of meaningful crossexamination or responsive testimony. This sleight of hand is, regrettably, common. The government has previously “subvert[ed] the requirements” of the federal rules, and “blur[r]ed the distinction between” expert and lay testimony. United States v. Figueroa-Lopez, 125 F.3d 1241, 1246 (9th Cir. 1997). It also frequently discloses expert witnesses way beyond the deadlines set forth in Rule 16. See United States v. Yagi, 2013 WL 10570994, at *16 (N.D. Cal. Oct. 17, 2013); United States v. Cerna, 2010 WL 2347406, at *1 (N.D. Cal. June 8, 2010). This appeal is an opportunity to call the government to account for these harmful practices.
