WHAT IS AN EXPERT WITNESS?

An Expert Witness in animal behaviour and animal welfare provides an opinion in legal cases involving animals, based on information that they have personally observed, or information that was provided by others.

An Expert Witness's role is to assist the ‘trier of fact’, whether this be a Court, an Arbitrator, an Appeal Board, or a Jury. Experts should not advocate for either party. An expert’s duty is to be independent, impartial, and unbiased.
