Seems like a good sign to me as well. And if the case is judged on ROE, we win.
Obviously, the prosecution didn’t feel enough confidence in their case without cooking up a deal with Mendoza. So they don’t think they can win on an ROE basis alone.
We still don’t know if the IO is dismissing Mendoza’s testimony or not, however. I would hope so. But he may have heard all he needed to hear during the hearing so is not asking for further arguments about it.
