CIFS, the Forensic Justice Project, and forensic science scholars and legal professionals filed this amicus brief on the Supreme Court of Oregon to Odell Adams’ case. This 2026 briefs follows our 2022 brief in the Appeals Court of Oregon which lead to the court ruling that opinions based on the pattern matching method that purport to identify the particular weapon from which a bullet or casing was fired are not scientifically valid and therefore inadmissible. This brief asks the Supreme Court to affirm the Appeal’s Court ruling.

Kate Judson of CIFS and various other legal scholars filed this amicus brief in the Court of Appeals of the State of Oregon to Odell Adams’ case to argue that the court should properly apply the preponderance standard for admissibility and find that opinions based on the pattern matching method that purport to identify the particular weapon from which a bullet or casing was fired are not scientifically valid and therefore inadmissible.
