Evidence – Medical evidence. The Queen's Bench Division dismissed an appeal of the defendant in regard to the decision of a master in a 'show cause' hearing in a mesothelioma claims provided for in CPR 6 PD 3.6D. The master had been entitled to reach the conclusion on the evidence presented to him and also in the light of his experience in dealing with cases of that nature. It was possible that another master would have permitted the case to go to trial, but that was not the test.
