Due to the lack of uniformity among trial courts, the Supreme Court of Tennessee granted an interlocutory appeal in Tennessee v. Scott to resolve a dispute regarding the admission of expert witness testimony. Traditionally, trial courts used a broad theme of "relevance and reliability" when considering expert testimony. The Court replaced that general theme with a four-prong test that included a "qualifications assessment, analytical cohesion, methodological reliability, and fundamental reliability.", The Court ruled that the trial court erred in excluding the expert witness testimony without this analysis.
