It's no less fallible to allow the ref to respond however they choose and stops the players manipulating a game's result (not that I think anyone would).
What? I'm not sure I'm following Mr. Marshall. The point is, this only comes up when there is no debate amongst players. When the issue is not contentious or dangerous. It seems pretty simple that the ref's decision being final is only necessary when there is a decision that needs to be made.
The ref will always be in a dangerous position of power, opening up decisions to anyone else simply allows more room for error/manipulation, it does not make for a more honest/accurate game.
How can a player manipulate results negatively in Matt's position?
