Here's my take based on what I heard in court. Mr. Cohen told the judge unless she ruled for the defendants on the 2 key claims, which would basically end the case in favor of the defendants, the defendants would want all 8 claims ruled on.
The judge said something like, "OK, if these 2 claims are ruled as dispositive to the case, I won’t rule on the other [6] claims.” I immediately took that to mean that if she ruled for the defendants on the 2 key claims, she would NOT rule on the remaining 6 claims. So “dispositive” clearly means in favor of the defendants, and in effect provides a final resolution to the case. So IMO, if she ruled in favor of the defendants on the 2 key claims, the defense would probably make a motion for dismissal of the case and the judge would probably grant it.
On the other hand, if the 2 key claims are ruled in favor of EDIG, the defense and EDIG would want the 6 other claims ruled on and the judge would use each parties’ written briefs to decide them.
Maybe Profundo can give his opinion since he was also in the courtroom.
