If that's the case, I don't think that automatically gives the chairman the right to set up witnesses.
With due respect to you, sir, I think that if that's the case, then you don't have that right, and what should have happened and still should happen is that a subcommittee meeting be called to discuss this matter that we've run out of witnesses, or if there are no more witnesses at the deadline, that a subcommittee meeting be called so that this issue can be discussed and perhaps a review be done of whether the study is going on too long.
