Expert witnesses are frequently needed in both civil lawsuits and criminal prosecutions in order to explain complicated evidence to the judge or jury. An electrician, for example, could be needed to testify in a personal injury lawsuit where the victim was injured by an electrical device, or in a criminal prosecution for breaking and entering to explain an alarm system. Rules regarding qualification of an expert witness will vary somewhat by jurisdiction; however, in most cases, the requirements to become an electrical expert witness are similar. Most courts will expect someone who plans to become an electrical expert witness to have the appropriate educational background and work experience to be able to testify effectively. A general reputation among his or her peers as an expert will also help someone to become an electrical expert witness.
The precise educational background expected of a witness who plans to testify as an electrical expert will depend somewhat on the type of case and the purpose of the testimony. For example, if the case is a lawsuit for defects in the design of an electrical appliance or something similar, then a degree in electrical engineering would likely be required of the witness. On the other hand, if the lawsuit is a personal injury case based on injuries caused by faulty wiring, then certification as an electrician may suffice. By the same token, if a witness is needed in a criminal prosecution to explain an alarm system, for example, then certification as an electrician may also be sufficient to become an electrical expert witness.
Along with the appropriate educational background, a person who aspires to become an electrical expert witness will also need to show the court a significant work history or practical experience in the field in which he or she plan to testify. While theory learned during school is important, in order to be considered an expert, a person needs to have experience where he or she actually applied the theories learned in school. In addition, courts often like to hear testimony that a person is regarded as an expert by peers within the field. For example, anyone who has supervisory experience, has published articles in the field, or has taught in the field may be considered an expert.
Ultimately, the court that hears the case in question will decide who may testify as an expert. In the United States, absent an agreement by the parties to the case, the court will hear testimony from the potential witness regarding his or her education and experience. The judge will then make a determination as to whether or not he or she may testify as an electrical expert witness.
