Wonder where it’s being held. There will be NDAs on the location of course, but people talk, and by necessity lots of people need to know this location. So plenty of people will know.
Might not even be in the UK, I guess. Don’t think there’s any legal bar to that, but I may stand (and happy to be) corrected. Theoretically could be via Zoom/Teams. Again, I don’t think there’s any legal bar to that, but I would say the parties would both need to agree to that mode of hearing.
There are some advantages to that format, especially if you have personnel supporting you, although definitely not in relation to cross examination. Maybe it will be hybrid.
Fuck knows!
