Witness vs Expert witness
Witnesses and expert witnesses play distinct roles in legal proceedings. A witness is an individual who has personal knowledge of the events or circumstances relevant to a case. They provide testimony based on their direct observations or experiences.
Regular witnesses recount facts, share their version of events, and assist in establishing a timeline or sequence of occurrences. Their credibility and ability to recall details accurately influence their impact on the case’s outcome.
Expert witnesses, on the other hand, are professionals with specialized knowledge, skills, or expertise in a particular field relevant to the case. These experts provide insights that the average person or juror might lack.
They offer informed opinions, analyses, or interpretations that can help clarify complex technical, scientific, or industry-specific matters. Courts often admit expert witnesses to aid in understanding intricate subjects, like medical diagnoses, financial intricacies, or engineering assessments.
While witnesses provide firsthand accounts, expert witnesses offer professional insights. Both types of witnesses contribute to the pursuit of truth within legal proceedings, offering different dimensions of information to help judges and juries make informed decisions.
Federal Rule of Evidence 701 deals with the admissibility of lay witness testimony whereas 702, deals with the admissibility of expert witnesses.
Professionals as Experts Witnesses
Expert witnesses, drawn from various professional fields, play a crucial role in legal proceedings by providing specialized insights that aid in understanding complex matters. These professionals, possessing extensive knowledge, training, and practical experience in some of the following areas:
- Cell site & Mobile phone analysists
- CCTV analysists
The value of expert witnesses lies in their ability to bridge the gap between intricate subjects and the comprehension of judges and jurors.
They offer expert opinions, analyses, and interpretations that can unravel convoluted technical details, scientific theories, or industry-specific practices. Their testimony serves to educate the court on matters that require specialized expertise, enabling a more informed and fair decision-making process.
It is worth noting that there is no such defined process to become a certified expert witness. The accepted requisites to be considered as an expert can usually be indicative through a specialized academic expertise or practical experience or a combination of both in the relevant subject of expertise.
However, the selection and credibility of expert witnesses are pivotal. Courts evaluate their qualifications, experience, and objectivity to ensure their testimony is reliable and unbiased.
Attorneys often choose expert witnesses who can present complex concepts in a clear and comprehensible manner, making their testimony accessible to those without expert backgrounds.
In essence, professional expert witnesses act as educators of the court, illuminating intricate aspects of a case that go beyond the understanding of laypeople. Their contributions aid in upholding the principles of justice by facilitating well-informed judgments based on a broader and more nuanced perspective.
Fundamental Functions of an Expert Witness
1. Scientific Function
Scientific expert witnesses provide specialized knowledge and opinions based on scientific principles, assisting the court in understanding complex technical or scientific matters relevant to the case. This includes collecting, testing, and evaluating evidence and forming an opinion as to that evidence.
2. Forensic Function
Forensic expert witnesses, on the other hand, apply their expertise to analyze and interpret evidence within a legal context (usually construed to be one experienced through one/more of their five senses), helping the court establish facts and make informed decisions based on the inference drawn from such sensory experience.
Legal Standard Governing Expert Witnesses
There is no such commonly fixed rule that governs the qualification of an individual as an expert. However, in common parlance, the admissibility of expert testimony is determined by the Daubert Standard. The following standards have been historically employed in the US for determining the question of admissibility of an expert’s testimony:
1. Frye standard
The “Fyre standard” refers to a legal standard for the admissibility of expert testimony that emerged from Frye v. United States (Frye v. United States, 293 F. 1013 (D.C. Cir. 1923) )in 1923.
Under the Frye standard, expert testimony is admissible if the scientific or technical principles on which the testimony is based are generally accepted within the relevant scientific community. In other words, the court would allow expert testimony if the underlying scientific theory or technique was widely accepted as valid by experts in the field, regardless of the expert’s individual qualifications.
2. Daubert standard
The Daubert standard, arising from the 1993 Daubert v. Merrell Dow Pharmaceuticals (Daubert v. Merrell Dow Pharmaceuticals, Inc., 509 U.S. 579) requires judges to act as gatekeepers, ensuring that expert opinions are both relevant and reliable.
For admissibility, the testimony must be based on sound scientific or technical principles, fitting the case’s issues, and assisting the fact-finder. The expert’s methodology should be testable, have a reasonable error rate, and ideally, be subject to peer review and publication.
3. Kumho standard
In 1999, Kumho Tire Co. v. Carmichael (Kumho Tire Co., Ltd. v. Carmichael, 119 S.Ct. 1167 (U.S. 1999)) extended the Daubert standard to non-scientific expert testimony, broadening its application beyond scientific and technical fields. This “Kumho standard” clarified that the reliability and relevance criteria for expert testimony applied to various disciplines, not just the sciences.
Courts now evaluate the methodology, principles, fit, testability, error rate, and acceptance of expert opinions across diverse areas, ensuring that all expert testimony meets the same rigorous standards for admissibility. The Kumho standard thus expanded the Daubert framework to encompass a wider array of expert testimony, promoting consistent and thorough scrutiny of evidence in legal proceedings.

This process aims to ensure that the expert’s testimony is reliable and credible before it is presented to the court.
