Cannot fully agree with Penny. Newly qualifieds are knowledgeable but their knowledge is limited to that learned in the class room. Now, who would want to be represented by a lawyer fresh out of law school/college, when standing in the dock of a criminal court. Who would you chose a George Carman QC or your novice lawyer. By the way I understand the youngest ever to take silk was 36.
Though I do agree that you don`t argue with a novice, there is little point in doing that. Arguing does not teach them anything.
