"If Amnesty International and other observers wanted to attend the hearing, they would have to queue for one of the four seats available in a public gallery."
I believe the gallery seats 40 but only four are available because of their rules on social distancing.
My understanding is that observers would need to have either one of the four available seats in the public gallery or a seat in the "overflow" rooms next to the court. Please note that the audio in the overflow room is reportedly very poor, what little I've read made it sound unreliable.
If some observers were allowed remote access, I think that is important.
They requested they get special status as "fair trial monitors". The judge said they get treated like everyone else.
They should have no better access than you or I. They are nobody - a group that got together to push their agenda. They have no standing in court different from any other member of the public.
They can monitor the trial without some special recognition.
No, their remote access request was denied. This is separate from any request for standing as an expert trial observer (which is a whole other can of worms).
