Federal Evidence Review is one of many websites I review on a regular basis. The blog has, “noted how the lower courts continue to grapple with the application of the Confrontation Clause to expert testimony based on the lack of clarity from recent Supreme Court cases. See, e.g., Confrontation Clause: Continuing Uncertainty For Expert Testimony Following Williams v. Illinois.”
Based on recent Supreme Court cases involving expert testimony under the Confrontation Clause, the Soto case provides some useful guidance. First, reexamination or "second analysis" testimony should be permitted where the second examiner conducts an independent review of the evidence and testifies about his or her independent conclusions. Second, to avoid challenges of impermissible bolstering, the second examiner should minimize reference to the conclusions of the first examiner. Any testimony about testimonial statements of the non-testifying first examiner may be subject to challenge under the Confrontation Clause.
The author discusses United States v. Soto, (1st Cir. 2013). Justice Souter is a member of the panel, although he did not write the opinion.
