The trial was originally scheduled to start on September 28, 2015. Then when they had the closed door session back in February, that trial date was "vacated" and a new date set for January 11, 2016. The reason given was partly to allow for a longer time for the pretrial motions, which were scheduled for April 30th, May 1st and September 28th.

But when they didn't finish the pretrials on May 1st, "in the two days provided", another hearing date was set for May 26th.

Does that mean the pretrials are now finished and the September 28th date is now open? Could the closed door hearing have been about delaying the trial to allow the others to proceed first? Is that why the Judge told the lawyers to "go and talk" on the break?

It's confusing, but I think they said that they hadn't finished the pre-trial motions and that they would still continue in September? But that was for the Bosma case, from what I can tell, not the other two. They wouldn't have the same judges, so I doubt that the date could be used for one of the other cases it wasn't scheduled for, but I'm not a lawyer, I don't know how that works.
