What is an expert witness?
An expert witness is a person who is qualified, either by actual experience or by careful study, to form definite opinions with respect to a division of science, technology, art, or a department of trade. He applies his scientific, technical, or any other specialized knowledge which will help the court understand the evidence or to determine a fact in the issue.
The importance of an expert witness in a judicial system
Expert witness testimony plays a vital role in the U.S. Judicial system. A jury is not necessarily equipped with the knowledge and background necessary to understand a case, especially if it involves technical aspects. The system of adjudicating such cases is often referred to as “the battle of the experts.” Hence, both the Plaintiff and Defendant are keen to retain credible experts in support of the case to persuade the jury.
How can an expert witness help to establish a case?
From the initial tasks of investigating, verifying and organizing facts to testifying at trial, the expert witnesses can make or break a case. Therefore, it becomes extremely important to do the homework and hire a qualified expert.
For example, in the case of a failure to administer the Tissue Plasminogen Activator (TPA) by an emergency physician, a neurologist could testify that the medical literature clearly supports the use of TPA for all qualifying patients, and failure to use it is a deviation from the standard of this care. Hence, if the accused emergency physician failed to apply the TPA then the court may rule in favor of the Plaintiff, taking into consideration the testimony of the expert witness.
Law governing expert discoveries
Federal Rules of Civil Procedure 26(a) (2) & (b) (4) govern the expert discovery rules. Prior to 2010, full disclosure of all the data and other information considered by the expert were required. However after 2010 Amendment, only the facts or data considered by the expert are required to be disclosed. Again, under the amended rules, all communications between the attorney and the testifying experts are protected from discovery.
Admissibility of expert testimony
All expert testimony is not admissible in the court of law. A qualified expert’s testimony may be rejected if it is not reliable or relevant to the facts in issue.
Rules governing admissibility of expert testimony are briefly stated as follows:
Between 1923 until 1993, federal judges and 45 states used the Frye rule based out of a federal case decided by the District of Columbia in 1923 ). Under Frye rule, the test for admissibility was that the scientific evidence must be based on the “generally accepted” principles within the specialized field in question, and that the reliability of such evidence is also generally accepted by the scientific world.
In 1974, Congress approved the Federal Rules of Evidence, which governed all evidentiary matters in federal court, including expert testimony. Specifically, Rule 702 reads:
“If scientific, technical, or other specialized knowledge will assist the trier of fact to understand the evidence or to determine a fact in issue, a witness qualified as an expert by knowledge, skill, experience, training, or education, may testify thereto in the form of an opinion or otherwise.”
In 1991 the case Daubert v. Merrell Dow Pharmaceuticals, Inc. determined that the trial court judge would act as the “gatekeeper” and would be responsible for determining reliability of scientific evidence, and for keeping “junk science” out of the courtroom. This new test takes place prior to trial, during a “Daubert” inquiry to determine admissibility of the expert testimony. Although this rule applies to all federal courts, it is not followed by all states in U.S.
