I'm not going to claim certainty in that regard but I don't believe sub judice to be restricted to those conditions. Alas, the legal counsel of the club has certainly pointed them in that direction which is all that really matters.
"We accept the need to communicate in much greater detail, and as soon as we can, we will.
However, we hope supporters understand that with legal matters pending we are unable to do so currently."
I would suggest the club should have said '...prefer to do so currently' rather than 'unable'. I very much doubt 'legal matters pending' would make it subject to any restrictions other than not embarrassing yourself.
