Argument(s)

The Daubert-Lanigan standard requires that courts assume a “gatekeeper” role regarding the admission of expert scientific and technical testimony. A robust application of the relevant standards is especially essential where, as here, proprietary algorithms are involved, to avoid violations of defendants’ constitutional rights and wrongful convictions predicated on unreliable evidence.
