The judge preferred the evidence of the Claimant's expert because of the Defendant's expert’s approach to his task as expert, his confusion over the proper approach to what prior art was and was not in the common general knowledge, the number of assertions he made which he was forced to resile from as incorrect, and his failure to acknowledge a key fact.

The issue in this judicial review did not turn on the expert evidence but the case illustrates the role of a medical reporting organisation (MRO) in a particular civil case and there are some general learning points.

Of note, the MRO did not arrange the correction of an erroneous date, it did not recognise how the evidence set out by the expert was seemingly insufficiently referenced and it did not recognise that there would be questions as to how some of the expert’s conclusions were reached.
