When the Director determines that during the auction, because of a player’s own error, one or more cards of that player’s hand were in position for the face to be seen by his partner, the Director shall require that every such card be placed face up on the table until the auction ends. Information from cards thus exposed is authorized for the non-offending side but unauthorized for the offending side (see Law 16C).
If it is a single card below the rank of an honour and not prematurely led, there is no further rectification (but see E following).
If it is a single card of honour rank or is any card prematurely led, offender’s partner must pass when next it is his turn to call (see Law 72C when a pass damages the non-offending side).
If two or more cards are so exposed offender’s partner must pass when next it is his turn to call (see Law 72C when a pass damages the non-offending side).
If the offender becomes declarer or dummy the cards are picked up and returned to the hand.
