A. Hand Found Deficient before Play Commences
When one or more hand(s) is/are found to contain fewer than 13 cards, with no hand having more than 13, before the opening lead is faced, the Director makes a search for any missing card, and:
1. if the card is found, it is restored to the deficient hand.
2. if the card cannot be found, the Director reconstructs the deal by substituting another pack.
3. the auction and play continue normally without alteration of any of the calls made, the restored hand being deemed to have contained all of its cards continuously throughout.
B. Hand Found Deficient Afterwards
When one or more hand(s) is/are found to contain fewer than 13 cards, with no hand having more than 13, at any time after the opening lead is faced (until the end of the Correction Period), the Director makes a search for any missing card, and:
1. if the card is found among the played cards, Law 67 applies.
2. if the card is found elsewhere, it is restored to the deficient hand. Rectification and/or penalties may apply (see 4 following).
3. if the card cannot be found, the deal is reconstructed using another pack. Rectification and/or penalties may apply (see 4 following).
4. a card restored to a hand under the provisions of Section B of this Law is deemed to have belonged continuously to the deficient hand. It may become a penalty card (Law 50), and failure to have played it may constitute a revoke.
C. Information from Replacement of a Card
Knowledge of the replacement of a card is unauthorized for the partner of a player whose hand contained an incorrect number of cards.
