Well sometimes there's an occasion when two duelists argue over a simple card ruling, and it happens a lot in tournament matches and both duelists end up getting mad at each other and eventually it ends up being unresolved because they quit and leave the duel. If that ever happens during a tournament match, all you have to do is make a screen shot and prove to the tournament host that you won and then the match victory is yours. Based on the proof you give us will decide who won the match. If neither duelist has any proof whatsoever, both are disqualified.

They shouldn't be disqualified if they resolve among themselves & duel again..
