State and federal defenders facing latent-print examiner testimony claiming individualization.

Daubert Challenge, Latent Fingerprint Individualization

FRE 702 motion + cross-exam bank to challenge latent fingerprint testimony. PCAST 2016 §5.4 grounded.

Concede foundational validity (per PCAST), then aim the cross-exam at PCAST's 1-in-18 false-positive rate, the number jurors must hear before they take the examiner's 'match' as certainty.

Summary of cited source

PCAST reported that latent-fingerprint false positives may occur as often as 1 in 18 cases (Miami-Dade 2014 study).

What this template gives you that the discipline-specific treatise does not.
  1. 01.

    Not undated boilerplate: the PCAST 2016 latent-print finding is source-linked to the report, so the citation is one you can verify before you file. PCAST classified latent prints as foundationally valid BUT with a substantial false-positive rate, most defense motions miss the second clause.

  2. 02.

    FBI's 2011 black-box study reported 1-in-306; the more conservative Miami-Dade 2014 study reported 1-in-18.

  3. 03.

    Examiners are still trained to claim 'individualization to the exclusion of all others', a phrasing PCAST explicitly rejected.

Authorities inside · source-checkable

The controlling authority this template is built on.

Before you buy, see the spine of the deliverable. Verbatim quotes are reproduced word for word from the opinion they cite; any attributed summary is labelled as a summary, never dressed up as a quote. Each entry links to its source so you can confirm it yourself. Nothing is paraphrased into a citation it does not support.

    Of the two appropriately designed black-box studies, the larger study (FBI 2011 study) yielded a false positive rate that is unlikely to exceed 1 in 306 conclusive examinations while the other (Miami-Dade 2014 study) yielded a considerably higher false positive rate of 1 in 18.

  • Supporting authorityVerbatim quote

    PCAST finds that latent fingerprint analysis is a foundationally valid subjective methodology—albeit with a false positive rate that is substantial and is likely to be higher than expected by many jurors based on longstanding claims about the infallibility of fingerprint analysis.
