"30. While it is up to the employer to make its own reasonable conclusions based on reasonable investigation, we find that the level of investigation was not thorough enough in the circumstances. Since the evidence was all circumstantial, we believe that a reasonably high level of investigation was required here. Mr Gordon and Miss Guise [who had given evidence before the Tribunal] could both have done more to try to establish whether Mr Lewis was telling the truth, especially about the pouch and whether he had delivered its contents. As it was, Miss Guise simply decided that there was a conflict of evidence, and left the matter of the pouch out of account in reaching her decision. However, what she was leaving out of account was the main plank in Mr Lewis' defence."
"30. Even though Miss Guise concluded that the key question was what had happened to the 59 items, Mr Lewis' version that he delivered letters to Copeland House on the Saturday, if established, would put the whole question of wilful delay into a very different light from that in which he was dismissed. We believe that no reasonable employer would have dismissed without further investigation in all the circumstances, and that the dismissal was unfair."
