Rhys Meggy appeared for the defence in this trial on indictment containing two counts of assault (ABH and a related common assault). The defendant was acquitted on count 1 and the Jury were unable to reach a verdict on count 2. The evidence of a prosecution expert witness - a consultant surgeon - had been substantially undermined following his concession under cross-examination that he lacked the requisite expertise to offer his opinion on the particular issue at hand.
