While you are here, surely those in the legal profession must have a pretty good idea of who the panel members are? There are only twelve to choose from, probably only six when the "lightweights" are taken out, and it can't be that difficult to match hearings and other dates with other workload of the likely suspects?
I may be way off the mark, I frequently am, but surely there must be a pretty good idea of who is on the panel by now, so the possibility of an unknown panel member with a long-term illness must be pretty remote?
