PART II
PENALTY CARD

LAW 52 - FAILURE TO LEAD OR PLAY A PENALTY CARD 

A. Defender Fails to Play Penalty Card

When a defender fails to lead or play a penalty card as required by Law 50 , he may not, on his own initiative, withdraw any other card he has played.

B. Defender Plays Another Card

1. Play of Card Accepted

(a) Declarer May Accept Play

If a defender has led or played another card when required by Law to play a penalty card, declarer may accept such lead or play.

(b) Declarer Must Accept Play

Declarer must accept such lead or play if he has thereafter played from his own hand or dummy.

(c) Penalty Card Remains Penalty Card

If the played card is accepted under either (a) or (b) preceding, the unplayed penalty card remains a penalty card.

2. Play of Card Rejected

Declarer may require the defender to substitute the penalty card for the card illegally played or led. Every card illegally led or played by the defender in the course of committing the irregularity becomes a major penalty card.
