CHAPTER VI
The Play 

PART V
CLAIMS AND CONCESSIONS

LAW 69 - ACQUIESCENCE IN CLAIM OR CONCESSION 

A. When Acquiescence Occurs

Acquiescence occurs when a contestant assents to an opponent's claim or concession, and raises no objection to it before his side makes a call on a subsequent board, or before the round ends. The board is scored as though the tricks claimed or conceded had been won or lost in play.

B. Acquiescence in Claim Withdrawn

Within the correction period established in accordance with Law 79C, a contestant may withdraw acquiescence in an opponent's claim, but only if he has acquiesced in the loss of a trick his side has actually won, or in the loss of trick that could not, in the Director's judgement, be lost by any normal play of the remaining cards. The board is rescored with such trick awarded to the acquiescing side.
