Rule 702 was applied by the United States Supreme Court in Daubert v. Merrell Dow Pharmaceuticals (1993). Prior to Daubert, the dominant criterion for the admissibility of expert testimony was the general standard of acceptance (Frye v. United States, 1923). In this test, an expert`s analysis should be based on principles and practices that are generally recognized as reliable by others working in the same field as the expert. In Daubert, the Court held that, according to the FRE, this general criterion of acceptance could no longer serve as the sole criterion of admissibility. An expert is not considered useful if his assumptions do not apply to the facts of the case. The expert must provide new and non-obvious information to the jury and ensure that there is no analytical gap in his reasoning. As a general rule, when a party appoints an expert, it must provide the other party with the expert`s contact information and the subject on which the expert will testify. This information is necessary so that the other party can begin researching the expert to show that the person is not actually an expert and is not allowed to draw conclusions in the case. In some cases, both parties will use expert witnesses who may even come to different conclusions. It may be important to know how qualified each expert is so that an argument can be made as to which statement the expert should be believed (credited) by the judge or jury. Expert testimony can have a huge impact on the judge`s final decision.

Therefore, federal Rules of Evidence (FRE) 702 strictly set the standards for expert eligibility. Rule 702 contains precise definitions of (a) the qualifications of expert witnesses and (b) the permissible level of testimony. An expert only meets the standards of a reliable expert if he meets the four pillars defined in FRE 702. At some point in the early stages of the procedure, the expert will submit a report outlining the areas of expert testimony. Even during the pre-trial period known as the „discovery,“ the opposing lawyer will generally want to adopt the expert`s testimony. A statement includes a series of oral questions that are put to the expert. The expert`s testimony is taken under oath and recorded by a court reporter, who prepares a transcript of the testimony that can be verified by the expert. Counsel for the party who appointed the expert has the opportunity to cross-examine the expert during testimony in order to clarify points or obtain additional information. An expert can be anyone who has knowledge or experience in a particular field or discipline that goes beyond what is expected of a layman. The duty of the expert is to provide the tribunal with an impartial opinion on certain aspects of the issues within his or her area of expertise that are being challenged. An expert witness is required when it is necessary to have expert opinions to help resolve a dispute.

This notice may lead to an early resolution of the dispute. An expert witness may be involved in legal proceedings and may be summoned to appear as a witness. The International Association of Professional Security Consultants has provided security experts with a methodology that meets these criteria in the form of „best practices“. It is included in both and Appendix F of this text. Experts, on the other hand, must be qualified to testify in their areas of expertise. Rule 703 of the Federal Rules of Evidence154 requires that an expert`s opinion be based on facts, data or other information that the expert has actually seen or heard or that has been disclosed to the expert. Rule 704155 allows the expert to testify to the ultimate question of fact, although at some point in history the ultimate theoretical doctrine has retained this right. Ultimately, the expert gives his or her assessment of the guilt or fundamental innocence of the accused, or of the truth or lie of a particular issue at trial.156 You may also be asked if you testified in another trial. It`s important to always be honest when you`re on the stand.

Perjury is a very serious crime and can carry prison sentences. All forensic experts should familiarize themselves with federal rules 701-706 and understand the purpose, intent and results of a successful Daubert challenge, where the opinion of an expert or the expert himself can be challenged and, if certain criteria are met, his testimony may be rejected. It is accepted and understood that experts can reasonably draw different conclusions from the same evidence. The expert is only qualified to comment on the case if his or her professional knowledge and skills help the jury better understand the evidence. The expert`s knowledge must go beyond the knowledge of the jury. He or she doesn`t necessarily need to be the best in the field, nor does he or she need to have all the facts about the case as long as his or her expertise is relevant. .
