LAW 71 - CONCESSION CANCELLED
A concession must stand, once made, except that within the Correction Period established under Law 79C the Director shall cancel a concession:
-
if a player conceded a trick his side had, in fact, won; or
-
if a player has conceded a trick that could not be lost by any normal play of the remaining cards.
The board is rescored with such trick awarded to his side.
