I tend to lend a hand to the other side as well, and I would leave that discretion to the chair and the clerk, but if for some reason you can't get witnesses to appear on a particular date specifically for BRM, after we've agreed on the witness lists, then obviously we don't want to waste committee time, so we can try to fill it.
I'm just checking to see how you want us to proceed. Should we still submit the witness lists for both studies? Again, it's just maximizing our committee time.
