Let's add a wrinkle.
The Umpires huddle. PU disagrees with BU and instructs BU that he needs to reverse the call. But BU stands by his initial ruling. This should have no effect on the field of play should it since the umpires discussed this privately. But what about their cooperation on the field after this and once it is protested and the protest is upheld what about the rest of the tourney. Finally brethren, have you ever had situations where you and your partner disagreed on a ruling and how did you handle it?
