Case Updates

The Claimant claimed he had suffered a substantial loss due to the destruction of two consignments of poppy heads by the Defendants. The parties were given permission to rely on the written evidence of expert accountants. The Claimant made an application to the Court for the accountancy expert witnesses to give oral evidence at the trial and an application to adduce evidence prepared by his son.

This was a significant and well reported patent case which was determined in the Intellectual Property List within the High Court last autumn.   

The technical aspects of the case required significant expert input from the panel involved.  The cross-examinations performed by leading Counsel for the parties were lengthy and complicated.  This led to confusion over what evidence was given when the transcripts were re-visited on subsequent trial days. The case shows how consideration should be given to experts who are being cross-examined so not to overload them with questions and information on the stand.

A psychiatrist whose evidence had often been admitted in capacity cases was assisted in this case of a hearing-impaired person by an interpreter who had British Sign Language (BSL) Level 1 training. Her assessment was subsequently criticised as she conducted the assessment without ‘suitable specialist learning support’.

For psychiatrists and psychologists, the case illustrates the importance, in the case of some hearing-impaired subjects, of being assisted, or of the assessment being carried out, by a psychologist or psychiatrist who has experience of the assessment and treatment of hearing-disabled people.

The judge in this patent case found that the claimants’ gene therapy expert had developed, quite possibly guided by lawyers, the understanding that the primary duty of an expert witness is not to say anything that may damage the instructing party’s case if it can be avoided.
