Various criteria of delimitation of these two roles in procceedings were taken into account. Yet, these proved to be illusive and unable to draw a clear-cut-line between a person to submit his testimony as a witness and a person who ought to stand before court as an expert. It can be easily seen in case of the so-called experts-witnesses. In the author's opinion, the basic difference between a witness and an expert nas a formai character and is related to the will of court examining knowledge of a given person in the form of determined evidence There are substantial differences between a witness who was called by court and an expert who was appointed by court and accepted his duties.polinfo:eu-repo/semantics/openAccessArtykuł
