No, no, no.
If the cases are all heard as one, then there will be no significant consideration given to the requirement to prove that each individual received TB4.
If ASADA convince the tribunal that TB4 was administered, that is not enough to convict any one individual player.
As Rines and Richard Ings have said many times, they need to establish that each and every individual they accuse had TB4 administered to him.
The 20 vials should not enable them to convict all 34 players en masse.
They need to establish who received what and when. They won't do that in a case where all 34 are heard together.
Secondly, if there is to be a joint case, what was the point of the latest delay, where ASADA have said they were preparing 34 separate SCNs, tailored to each player's circumstances?
