United States v. Scheffer

Edward Scheffer (defendant), an airman charged by court-martial with methamphetamine use after a positive urinalysis, sought to introduce a polygraph test result supporting his claim that he never knowingly used drugs, but the Military Rules of Evidence categorically excluded polygraph evidence, and the court-martial excluded it and convicted him. The Court of Appeals for the Armed Forces reversed on Sixth Amendment grounds, and the government sought review.
