If the rules are changed so that further play is impossible, or if the legality of some action cannot be determined with finality, or if some action appears equally legal and illegal, then a player may call for judgement on a statement to that effect. If the statement is judged true, then the same judge who judged the statement true must declare the most recent passed proposal X such that the statement was not true before the passage of proposal X, or declare that there is no such proposal. (Until the judge does this, the judgment is not valid.) If the judgement of true is not overruled, then the player who called for judgement is declared the winner of the game.
When a game ends by this manner and the judge has declared that there is no such proposal X, the game is ended, with no provisions for restarting it.
When a game ends by this manner and the judge has declared such a proposal X, the following actions are taken: - all players remain registered - the scores for all players are set to 0 (zero), - the rules and explicit game custom are reverted to the state they were in before proposal X was passed - the noticeboards are cleared - and a new game is begun.
This rule takes precedence over every other rule for determining the winner of the game.
