90. The penalty for a revoke—
I. Is at the option of the adversaries, who, at the end of the hand, may, after consultation, either take three tricks from the revoking player and add them to their own—or deduct the value of three tricks from his existing score—or add the value of three tricks to their own score;
II. Can be claimed for as many revokes as occur during the hand;
III. Is applicable only to the score of the game in which it occurs;
IV. Cannot be divided—i.e. a player cannot add the value of one or two tricks to his own score and deduct the value of one or two from the revoking player.
V. In whatever way the penalty may be enforced, under no circumstances can the suit revoking score Game, Grand Slam or Little Slam, that hand. Whatever their previous score may be, the side revoking cannot attain a higher score towards the game than twenty-eight.
91. A revoke is established, if the trick in which it occurs be turned and quitted—i.e. the hand removed from that trick after it has been turned face downwards on the table—or if either the revoking player or his partner, whether in his right turn or otherwise, lead or play to the following trick.
92. A player may ask his partner whether he has not a card of the suit which he has renounced; should the question be asked before the trick is turned and quitted, subsequent turning and quitting does not establish the revoke, and the error may be corrected, unless the question be answered in the negative, or unless the revoking player or his partner have led or played to the following trick.
[Note.—A negative answer to the question does not in itself establish the revoke, apart from turning and quitting the trick, or some subsequent act of play.—Ed.]
93. At the end of the hand, the claimants of a revoke may search all the tricks.
94. If a player discover his mistake in time to save a revoke, any player or players who have played after him may withdraw their cards and substitute others, and their cards withdrawn are not liable to be called. If the player in fault be one of the dealer's adversaries, the dealer may call the card thus played in error, or may require him to play his highest or lowest card to that trick in which he has renounced.
95. If the player in fault be the dealer, the eldest hand may require him to play the highest or lowest card of the suit in which he has renounced, provided both of the dealer's adversaries have played to the current trick; but this penalty cannot be exacted from the dealer when he is fourth in hand, nor can it be enforced at all from Dummy.
96. If a revoke be claimed, and the accused player or his partner mix the cards before they have been sufficiently examined by the adversaries, the revoke is established. The mixing of the cards only renders the proof of a revoke difficult, but does not prevent the claim, and possible establishment, of the penalty.
