LAW XI.—Miscellaneous.
Sec. 1. If any one calls attention in any manner to the trick before his partner has played thereto, the adversary last to play to the trick may require the offender’s partner to play his highest or lowest of the suit led, and, if he has none of that suit, to trump or not to trump the trick.
Sec 2. A player has the right to remind his partner that it is his privilege to enforce a penalty and also to inform him of the penalty he can enforce.
Sec. 3. A player has the right to prevent his partner from committing any irregularity, and for that purpose, may ask his partner whether or not he has a card of a suit to which he has renounced on a trick which has not been turned and quitted.
Sec. 4. If either of the adversaries, whether with or without his partner’s consent, demands a penalty to which they are entitled, such decision is final; if the wrong adversary demands a penalty or a wrong penalty is demanded, or either adversary waives a penalty, none can be enforced except in case of a revoke.
Sec. 5. If a player is lawfully called upon to play the highest or lowest of a suit, to trump or not to trump a trick, to lead a suit or to win a trick, and unnecessarily fails to comply, he is liable to the same penalty as if he had revoked.
Sec. 6. If any one leads or plays a card, and then, before his partner has played to the trick, leads one or more other cards, or plays two or more cards together, all of which are better than any of his adversaries hold of the suit, his partner may be called upon by either adversary to win the first or any subsequent trick to which any of said cards are played, and the remaining cards so played are liable to be called.
