54. If the right-hand adversary of the dealer double before his partner has asked "May I lead?" the declarer 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 as described in paragraphs 52, 53, 55.
55. The process of re-doubling may be continued indefinitely.[B] The first right to continue the re-doubling on behalf of a partnership belongs to that player who has last redoubled. Should he, however, express himself satisfied, the right to continue the re-doubling passes to his partner. Should any player re-double out of turn, the adversary who last doubled shall decide whether or not such double shall stand. If it is decided that the re-double shall stand, the process of re-doubling may continue as described in this and foregoing laws (52 and 53). If any double or re-double out of turn be not accepted there shall be no further doubling in that hand. Any consultation between partners as to doubling or re-doubling will entitle the maker of the trump or the eldest hand, without consultation, to a new deal.
56. If the eldest hand lead before the doubling be completed, his partner may re-double only with the consent of the adversary who last doubled; but such lead shall not affect the right of either adversary to double.
[B] In some clubs, doubling ceases whenever the value of the odd trick exceeds one hundred points; in other clubs the limit is placed at two hundred points.
57. When the question, "May I lead?" has been answered in the affirmative or when the player who has the last right to continue the doubling, expresses himself satisfied, the play shall begin.
58. Should the eldest hand lead without asking permission, his partner may double, but only if the maker of the trump consent.
59. 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 as described in Laws 52, 53, 55.
60. 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.
