In United States v. Llera Plaza, 188 F. Supp. 2d 549 (E.D. Pa. 2002), a federal district initially limited expert opinion testimony on fingerprint identifications because the government was unable to show that such identifications were sufficiently valid and reliable under Federal Rule of Evidence 702. Then, the court withdrew the opinion. This article reproduces an exchange of notes on the initial opinion submitted by five law professors.
