This is a good question. Coverage of this trial has been hard to come by. Craig Murray is posting details to his blog but he's also not the most objective witness. Still, he wrote the following[0]:
"Magistrate Baraitser then made a statement about access to the court by remote hearing, by which she meant online. She stated that a number of access details had been sent out by mistake by the court without her agreement. She had therefore revoked their access permissions."
When I read this, I thought that only certain people had their remove access revoked, for instance Amnesty International. But then he goes on...
"Baraitser went on to say that it was important that the hearing was public, but she should only agree remote access where it was 'in the interests of justice', and having considered it she had decided it was not. She explained this by stating that the public could normally observe from within the courtroom, where she could control their behaviour. But if they had remote access, she could not control their behaviour and this was not in the 'interests of justice'."
That sounds to me like _everyone's_ remote access had been revoked.
