Copyright – Infringement. The claimant issued proceedings against the defendants for infringement of his copyright. The judge found that the claimant had licensed the second defendant to use a tool that the claimant had developed, but no wider consent had been given. The defendants appealed. The Court of Appeal, Civil Division, in dismissing the appeal, held that the claimant's lies had been fatal to his claim in respect of the activities of the second defendant, but not the first defendant. Further, he had not misdirected himself in law and had arrived at conclusions which had been open to him on the evidence.
