77. If the declarer lead out of turn, either from his own hand or dummy, he incurs no penalty, but he may not rectify the error unless directed to do so by an adversary.[16] If the second hand play, the lead is accepted.

78. If an adversary of the declarer lead out of turn, and the declarer follow either from his own hand or dummy, the trick stands. If the declarer before playing refuse to accept the lead, the leader may be penalized as provided in Law 76.

79. If a player called on to lead a suit have none of it, the penalty is paid.

CARDS PLAYED IN ERROR.

80. Should the fourth hand, not being dummy or declarer, play before the second, the latter may be required to play his highest or lowest card of the suit led, or to win or lose the trick. In such case, if the second hand be void of the suit led, the declarer in lieu of any other penalty may call upon the second hand to play the highest card of any designated suit. If he name a suit of which the second hand is void, the penalty is paid.[17]

81. If any one, except dummy, omit playing to a trick, and such error be not corrected until he has played to the next, the adversaries or either of them may claim a new deal; should either decide that the deal stand, the surplus card (at the end of the hand) is considered played to the imperfect trick, but does not constitute a revoke therein.[18]

82. When any one, except dummy, plays two or more cards to the same trick and the mistake is not corrected, he is answerable for any consequent revokes he may make. When the error is detected during the play, the tricks may be counted face downward, to see if any contain more than four cards; should this be the case, the trick which contains a surplus card or cards may be examined and such card or cards restored to the original holder.[19]

THE REVOKE.[20]

83. A revoke occurs when a player, other than dummy, holding one or more cards of the suit led, plays a card of a different suit. It becomes an established revoke when the trick in which it occurs is turned and quitted by the rightful winners (i.e., the hand removed from the trick after it has been turned face downward on the table), or when either the revoking player or his partner, whether in turn or otherwise, leads or plays to the following trick.

84. The penalty for each established revoke is:
