Should the right-hand adversary of the dealer ask permission to lead, the eldest hand does not thereby lose his right to double. Should the right-hand adversary of the dealer double before his partner has asked "May I lead?" the maker of the trump shall have the right to say whether or not the double shall stand. If he decide that the double shall stand, the process of re-doubling may continue.
If the right-hand adversary of the dealer lead out of turn, the maker of the trump may call a suit from the eldest hand, who may only double if the maker of the trump consent.
A declaration as to doubling or re-doubling once made cannot be altered.
DUMMY
As soon as the eldest hand has led, the dealer's partner shall place his cards face upward on the table, and the duty of playing the cards from that hand shall devolve upon the dealer, unassisted by his partner.
Before exposing his cards, the dealer's partner has all the rights of a player, but after his cards have been shown the dealer's partner takes no part whatever in the play, except that he has the right——
a To ask the dealer whether he has none of the suit in which he may have renounced.
b To ask the dealer when called upon to play his highest or lowest card whether he has conformed to the penalty.
