This passage applies just as much to a court chairman as it does to a DJ:-
Owing to the considerable pressure on a district judge to deal with work expeditiously, there can be a temptation to speak first and think afterwards.
Wherever possible, it is helpful to avoid painting oneself into a corner. Rather than making a dogmatic statement (‘This is the position’), invite assistance from the advocate (‘I would be grateful for your assistance in this matter; it seems to me on fi rst consideration that . . ., but I would welcome your thoughts’). Wherever possible use open questions, i.e. questions that do not suggest any particular answer, rather than making a direct statement, until you are absolutely sure.
