During a Daubert challenge in court, which argument could weaken the case for a forensic tool that hasn't been peer-reviewed?

• A. The tool hasn't been tested by the ISO
• B. Only the local law enforcement should use the tool
• C. The tool has not been peer-reviewed or accepted by peers
• D. You are not certified for using the tool

Answer: (C)

In a Daubert challenge, judges assess whether a forensic method is scientifically valid and reliable enough to be admitted as evidence. Peer review and acceptance by peers are crucial indicators because they provide independent scrutiny, validation, and consensus on how well the method works, its error rates, and appropriate use. If a tool hasn’t been peer-reviewed or accepted by the scientific community, there’s less assurance that its results are reliable, which makes it easier for the defense to argue that the method isn’t scientifically sound for court purposes. This directly undermines the criteria Daubert uses to judge admissibility. The other options don’t target the method’s scientific validity in the same way. Relying on ISO testing or certification of the user doesn’t address whether the method itself has been independently validated, which is the core concern in a Daubert challenge. Limiting use to a specific group or requiring the operator to be certified affects procedural aspects or weight of the testimony, but not the fundamental reliability of the tool as judged by peer-reviewed validation.
