John Pierce v Her Majesty’s Advocate: 1981

A forensic scientist had been called as an expert witness at a criminal trial. He had made an unjustified assumption but had not disclosed the making of the assumption to the court.
Held: The court concluded that the witness had been discredited, not only as a scientist, but also as a witness upon the accuracy, fairness and objectivity and of whose evidence reliance could be placed: ‘This was in our judgment, conduct on the part of an expert witness which demonstrated a complete misunderstanding of the role of scientific witnesses in the Courts, and a lack of the essential qualities of accuracy and scientific objectivity which are normally to be taken for granted.’
