Policing The Bases Of Modern Expert Testimony, Ronald L. Carlson

Scholarly Works

The expanding array of scientific (as well as some not-so-scientific) specialties available as sources for testimony raises hard questions. Will courts require that the witness' opinions be reasonably based upon trustworthy data? How far must judges inquire into the practice of other experts in the same field prior to allowing the trial witness to proffer an expert opinion? How much of the expert's supporting data will be received in evidence? This Essay addresses these and other important questions affecting the scope of modern expert testimony.
