Easy solution is that the Umpire makes the call, and then there must be conclusive evidence that DISPROVES what he has said to overturn his decision. Thats how it works in the NFL, and pretty much in Rugby (referee asks if there is any reason to give or not give the try).
Absolutely agree. From what I understand, that is how it is supposed to work. The problem, as with any new system, is that the people implementing it don't know the rules. Maybe a change in wording would be better, as you suggest; if the process involves the player invoking a challenge, and the umpire who made the decision then calling the man upstairs and saying 'is there conclusive evidence that I was wrong?', it makes it much clearer for all concerned.
