United States v. Gutierrez-Castro
Facts
The government sought to call James McNutt, a Border Patrol/Forensic Document Laboratory fingerprint specialist, to testify about inked fingerprint analysis and compare fingerprints taken from Gutierrez-Castro after arrest with fingerprints on prior deportation documents. McNutt had approximately fifteen years of fingerprint experience, FBI-sponsored training, and repeated IAI certification and recertification. He testified that fingerprint analysts use the ACE-V methodology and that fingerprint-analysis error rates are considered very low, although hard to determine precisely. The defendant challenged both McNutt's qualifications and the reliability of fingerprint analysis, and argued the jury should not hear him presented as an expert.
Issue
Whether the government could present McNutt's testimony on inked fingerprint analysis and identity under Rule 702 and Daubert. Also, whether the court should permit the jury to hear McNutt designated or certified as an expert witness.
Rule
Under Rule 702, a witness may testify in the form of opinion testimony if qualified by knowledge, skill, experience, training, or education, and if the testimony is based on sufficient facts or data, is the product of reliable principles and methods, and those principles and methods are reliably applied to the facts. In assessing reliability under Daubert, the court may consider whether the method has been tested, subjected to peer review and publication, its error rate, the existence and maintenance of standards, and general acceptance in the relevant community; weaknesses that bear on weight and credibility may be exposed through cross-examination rather than exclusion.

The defense argues Ortiz is not qualified because certification standards vary and she has not recently taken a formal class. How should the court most likely rule?
