A card prematurely exposed (but not led, see Law 57) by a
defender is a penalty card unless the Director designates otherwise (see Law 49
and Law 23 may apply).
A penalty card must be
left face up on the table immediately before the player to whom it belongs,
until a rectification has been selected.
A single card below the
rank of an honour exposed unintentionally (as in playing two cards to a trick,
or in dropping a card accidentally) becomes a minor penalty card. Any card of
honour rank, or any card exposed through deliberate play (for example in
leading out of turn, or in revoking and then correcting), becomes a major
penalty card; when one defender has two or more penalty cards, all such cards
become major penalty cards.
When a defender has a
minor penalty card, he may not play any other card of the same suit below the
rank of an honour until he has first played the penalty card, but he is
entitled to play an honour card instead. Offender’s partner is not subject to
lead restriction, but information gained through seeing the penalty card is
unauthorized (see E following).
When a defender has a
major penalty card, both the offender and his partner may be subject to
restriction, the offender whenever he is to play, the partner whenever he is to
lead.
(a) to require*
the defender to lead the suit of the penalty card, or to prohibit* him from
leading that suit for as long as he retains the lead (for two or more penalty
cards, see Law 51); if declarer exercises either of these options, the card is
no longer a penalty card and is picked up.
(b) not to require or prohibit a lead, in which case the
defender may lead any card; the penalty card remains a penalty card**. If this option is selected
Law 50D continues to apply for as long as the penalty card remains.
E. Information from a Penalty Card
1. Knowledge
of the requirements for playing a penalty card is authorized information for
all players.
2. Other
information derived from sight of a penalty card is unauthorized for the
partner of the player who has the penalty card (but authorized for declarer).
3. If the Director judges that the exposed card conveyed
such information as to damage the non-offending side he shall award an adjusted
score.
* If the player is unable to lead as required see Law 59.
**If the partner of the defender with the penalty card
retains the lead, and the penalty card has not yet been played, then all the
requirements and options of Law 50D2 apply again at the following trick.
