EPI Environmental Technologies Inc and Another v Symphony Plastic Technologies Plc and Another: ChD 21 Dec 2004

The claimant had developed an additive which would assist in making plastic bags bio-degradable. They alleged that, in breach of confidentiality agreements, the defendants had copied the product. The defendants said the confidentiality agreement was ineffective.
Held: The part of the information copied was not confidential having been previously disclosed. When expert witnesses conflicted, the witness’s performance should be looked at in the light of his or her evidence as a whole. Mistakes in one part of a witness’ evidence may not affect the whole of their evidence.
Peter Smith J said: ‘A witness may lie in a stupid attempt to bolster a case, but the actual case nevertheless remains good irrespective of the lie. A witness may lie because the case is a lie.’
