The decision by Judge Ellis on this motion is important.
If he decides to allow the trial to go forward on the basis of the indictment as long as it meets the criteria he has asked for, then he just greased the wheels for the next wave of Mueller indictments.
If he throws the case out on the grounds of jurisdiction, the charges won't go away. What is admissible as evidence is still a question. The only certain result is that the trial will happen much later. This result would slow other cases down.
What will the decision be? Watching the courts do stuff is harder than waiting for paint to dry.

The hearing of motions before Ellis is still underway. Weissmann filed a response on a list of the Manafort teams' requests on 5/14. Included in the filing is a response to the matter of unredacted materials under seal:

“To respond fully to the arguments in Manafort’s motion to suppress, the government needs to refer to portions of the warrant materials that remain under seal in this court and that are the subject of ongoing litigation in the District of Columbia,” Weissman says in the motion. “At the same time, the government is filing on the public docket a redacted version of its memorandum that blacks out those references but otherwise strives to minimize the amount of material withheld from the public.”

Allowing the government to file an unredacted version of its memorandum under seal would “balance” the government’s, the public’s and even Manafort’s own interests, the government says.

On May 4th, Ellis gave the prosecutors two weeks to produce more information regarding the instructions given by Rosenstein to the Special Prosecutor. So that is coming due tomorrow.

Now that Ellis can see behind the curtain, maybe he will make a ruling next week.

I am not sure the tempest is over. The official start of the trial is one thing. Ellis has still not ruled on the jurisdiction question. Could he not kick the can further down the road?
