But if any declaration as to doubling, or not doubling, shall have been made, or if a new deal be not claimed, the declaration wrongly made shall stand. The eldest hand is the player on the left of the dealer.
47. Should the dealer's partner pass the declaration to the dealer it shall be the right of the eldest hand to claim a new deal or to compel the offending player to declare the trump; provided, that no declaration as to doubling has been made.
48. If either of the dealer's adversaries make or pass the declaration, the dealer may, after looking at his hand, either claim a new deal or proceed as if no declaration had been made.
49. A declaration once made cannot be altered.
DOUBLING, RE-DOUBLING, ETC.
50. The effect of doubling, re-doubling, and so on, is that the value of each trick above six is doubled, quadrupled, and so on.
51. After the trump declaration has been made by the dealer or his partner, their adversaries have the right to double. The eldest hand has the first right. If he does not wish to double, he may ask his partner, "May I lead?" His partner shall answer, "Yes" or "I double."
52. If either of their adversaries elect to double, the dealer and his partner have the right to re-double. The player who has declared the trump shall have the first right. He may say, "I re-double" or "Satisfied." Should he say the latter, his partner may re-double.
53. If the dealer or his partner elect to re-double, their adversaries shall have the right to again double. The original doubler has the first right.
