On Point: c. Expert testimony

On review of a court of appeals certification; case activity (including briefs)

Issue (from certification):

Does it violate a defendant’s rights under the Confrontation Clause of the Sixth Amendment to the United States Constitution for the State to introduce at trial a toxicology report identifying certain drugs in a deceased victim’s system and/or testimony of a medical examiner basing his/her cause-of-death opinion in part on the information set forth in such a report, if the author of the report does not testify and is not otherwise made available for examination by the defendant?

State v. Miguel Muniz-Munoz, 2014AP702-CR, 3/1/16, District 1 (not recommended for publication); case activity (including briefs)

By the time Muniz-Munoz went to trial for first degree intentional homicide, the medical examiner who conducted the autopsy of the victim was dead. The trial court allowed another medical examiner who reviewed the case record to give his independent opinion about the cause of the victim’s death. This did not violate Muniz-Munoz’s right to confrontation.

State v. Michael R. Griep, 2015 WI 40, 4/23/15, affirming a published court of appeals decision; majority opinion by Justice Roggensack; case activity (including briefs)

Opinion testimony by a qualified expert based on data produced by an unavailable forensic lab analyst doesn’t violate a defendant’s right to confrontation if the testifying expert formed an “independent” opinion based on a review of the unavailable analyst’s data.

State v. Jason S. VanDyke, 2015 WI App 30; case activity (including briefs)

In this prosecution for reckless homicide by delivery of heroin, VanDyke’s right to confrontation was violated where the medical examiner relied on the toxicology report of an out-of-state drug testing lab to conclude the victim had died of a heroin overdose, the toxicology report was admitted into evidence as part of the autopsy report, but no witness from the lab was called to testify about the toxicology testing.

On review of a published court of appeals decision; case activity

Issue (composed by On Point)

Was Griep’s right to confront the witnesses against him violated by allowing the supervisor of an unavailable lab analyst to testify to his opinion about the defendant’s BAC based entirely on the report prepared by the unavailable analyst?

Court of appeals certification; case activity

Issue certified:

Is an OWI defendant’s right to confront the witnesses against him violated when a supervisor of the state crime lab testifies that a lab report prepared and certified by another, but unavailable, lab analyst establishes the defendant’s illegal blood alcohol concentration?  Does it make a difference that the lab supervisor said it was “his” opinion even though he did not perform any of the testing himself and simply noted that the unavailable analyst followed the proper protocol?
