Forensic electrical engineering is a branch offorensic engineering, and is concerned with investigating electrical failures and accidents in a legal context. Many forensic electrical engineering investigations apply to fires suspected to be caused by electrical failures.[1] Forensic electrical engineers are most commonly retained by insurance companies or attorneys representing insurance companies, or by manufacturers or contractors defending themselves againstsubrogation by insurance companies. Other areas of investigation includeaccident investigation involvingelectrocution, andintellectual property disputes such aspatent actions. Additionally, since electrical fires are most often cited as the cause for "suspect" fires, an electrical engineer is often employed to evaluate the electrical equipment and systems to determine whether the cause of the fire was electrical in nature.
The ultimate goal of these investigations is often to determine the legal liability for afire or otheraccident for purposes ofinsurancesubrogation or an injury lawsuit. Some examples include:
Forensic electrical engineers are also involved in somearson and set-fire investigations; while it is not common for arsonists to cause electrical failures to ignite fires, the presence of electrical appliances and systems in many fires scenes often requires them to be evaluated as possible accidental causes of the fire. Some electrical means of ignition, when discovered, are fairly obvious to anorigin and cause investigator and most likely do not require consulting with a forensic electrical engineer. (Note that "arson" refers specifically to a criminal act, subject to criminal prosecution; a more general term is a "set fire". A homeowner setting a fire deliberately in order to defraud an insurance company might be prosecuted for arson by a government body; however, the insurance company would concern itself only with denying the insurance claim, possibly leading to a civil lawsuit.)
Patent disputes may also require the expert opinion of an electrical engineer to advise a court. Issues in conflict may include the precise meaning of technical terms, especially in thepatent claims, theprior art in a particular product field and theobviousness of various patents.
Most states have a statute of ultimate repose (similar to, but not to be confused with, a statute of limitations) that limits the length of time after which a party can legally be held liable for their negligent act or defective product. Many states have a "useful life" statute of ultimate repose. Therefore, a determination of the length of time the product would normally be expected to be used before wearing out needs to be made. For example, a refrigerator might have a longer "useful life" than an electric fan; an airplane might have a longer useful life than a car. Some states pick an arbitrary number of years for the statute of ultimate repose. It may be short (six or seven years) or longer 15 or 25 years. If a coffee maker starts on fire after the statute of ultimate repose has expired, the manufacturer can no longer be held liable for manufacturing or design defects. The statute of ultimate repose is different from the statute of limitations. In a state with a short statute of ultimate repose, it is common that a person's right to bring a claim in court expires before their injury ever occurs. Thus, if a defective product (for example a car) caused a collision when the steering failed, but the collision occurred after the expiration of a statute of ultimate repose, no claim could be brought against the manufacturer for selling a defective product. The right to bring the claim expired before the claim even occurred.
