An expert witness is a professional with specific skills and knowledge on a subject and will be asked to testify in court. For example, a Restaurant Expert Witness can attest that a given food did not cause food poisoning and explain why this did not happen (based on his knowledge, scientific proof, experience, etc.). This is just an example, but a restaurant expert witness can testify on many other topics related to food safety and the food industry. Expert witnesses represent third-party experts, and their testimony can be used in court. Expert witnesses can offer their opinion based on specific skills and the knowledge and experience they possess.
Typically, a Restaurant Expert Witness or another type of witness will be called to testify whenever necessary and when an expert’s opinion is needed on a given topic. His unbiased opinion may help solve significant disputes in court. Regarding expert witnesses, each jurisdiction has different guidelines and rules regarding when he needs to testify or when his opinion is needed to settle a dispute. For example, digital forensics experts can offer their opinion on specific digital evidence. The witnesses are generally called to explain an aspect so non-experts can understand it scientifically. There are many types of expert witnesses available who specialize in different topics- from economics and engineering to the medical field or the food service industry.
Expert witnesses must adhere to specific rules and regulations and are responsible under the federal laws of evidence. For example, the expert witness must be a qualified professional. He must prove specific expert skills, experience, and knowledge that allow him to intervene and help solve given legal matters. Then, an expert witness must be helpful because his assumptions and opinions must apply to the facts presented in the case. Also, the expert witness must always give an honest and unbiased view, even if this is not serving the client’s best interest.
