61. A declaration once made cannot be altered.
Dummy.
62. As soon as a card is led, whether in or out of turn, the dealer's partner shall place his cards face upwards on the table, and the duty of playing the cards from that hand, which is called Dummy, and of claiming and enforcing any penalties arising during the hand, shall devolve upon the dealer, unassisted by his partner.
63. After exposing Dummy, the dealer's partner has no part whatever in the game, except that he has the right to ask the dealer if he has none of the suit in which he may have renounced. If he call attention to any other incident in the play of the hand, in respect of which any penalty might be exacted, the fact that he has done so shall deprive the dealer of the right of exacting such penalty against his adversaries.
64. If the dealer's partner, by touching a card, or
otherwise, suggest the play of a card from Dummy, either of the adversaries may, but without consulting with his partner, call upon the dealer to play or not to play the card suggested.
65. When the dealer draws a card, either from his own hand or from Dummy, such card is not considered as played until actually quitted.
66. A card once played, or named by the dealer as to be played from his own hand or from Dummy, cannot be taken back, except to save a revoke.
67. The dealer's partner may not look over his adversaries' hands, nor leave his seat for the purpose of watching his partner's play.
68. Dummy is not liable to any penalty for a revoke, as his adversaries see his cards. Should he revoke, and the error not be discovered until the trick is turned and quitted, the trick stands good.
