78. If any player lead out of turn and the other three follow him, the trick is complete and the error cannot be rectified; but if only the second, or second and third play to the false lead, their cards may be taken back; there is no penalty against anyone except the original offender, who, if he be one of the dealer’s adversaries, may be penalised as provided in Laws 60 and 76.

79. In no case can a player be compelled to play a card which would oblige him to revoke.

80. The call of an exposed card may be repeated at every trick until such card has been played.

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

CARDS PLAYED IN ERROR

82. Should the third hand not have played and the fourth play before his partner, the latter (not being dummy or dealer) may be called upon to play his highest or lowest card of the suit played, or to win or lose the trick.

83. If anyone, not being dummy, omit playing to a former trick and such error be not corrected until he has played to the next, the adversaries may claim a new deal; should they decide that the deal stands good, the surplus card at the end of the hand is considered to have been played to the imperfect trick, but does not constitute a revoke therein.

84. If anyone (except dummy) play two cards to the same trick, or mix a card with a trick to which it does not belong, and the mistake be not discovered until the hand is played out, he is answerable for any consequent revokes he may have made. If during the play of the hand the error be detected, the tricks may be counted face downward, in order to ascertain whether there be among them a card too many; should this be the case, the trick which contains a surplus card may be examined and the card restored to its original holder, who (not being dummy) shall be liable for any revoke he may meanwhile have made.

THE REVOKE

85. 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. The penalty for a revoke takes precedence of all other counts.
