In my 99ers yesterday, East was playing 4
♥.
North made a lead out of turn (
♣10), but before the East exercised her rights, South played the
♣K. I was then called to the table. These were not simultaneous leads, south just had a brain fart and was playing prematurely.
So I give East her options, and the lawyer in her can't resist the option of having two penalty cards on the table.
So I'm thinking - "two penalty cards" and take a quick look at Law 51, but that section deals with only
one player having two penalty cards. L57 and L58 looked like they might apply, but I couldn't find anything conclusive.
In the end, South led an off-suit Ace, so declarer exercised her rights under 50D2, barred a club lead and the
♣K was returned to hand. In time, the
♣10 was disposed of as well.
Is there a section that discusses penalty cards held by two different players?
Somehow, I don't feel as though this was handled properly however.

Accepting as a fact that South really led his
♣K subsequent to the lead out of turn of the
♣10 so that Law 58A does not apply, this
♣K is a defender's card prematurely exposed in an act of leading or playing it so it becomes a major penalty card (regardless of its rank).
The Director will now apply Law 54 on the opening lead of
♣10 from North out of turn :
a: If Declarer accepts this lead out of turn then South must follow suit with his
♣K and the case is "closed".
b: If declarer does not accept the lead out of turn then the
♣10 (also) becomes a major penalty card and Declarer has the choice of:
b1: require or prohibit the lead of a club from South, in which case the
♣10 ceases to be a penalty card and is restored to North's hand while South must lead a card according to Declarer's decision. If this decision is a request for a club then South must play his
♣K, otherwise South plays any of his cards (other than a club) at his own choice and the
♣K remains a major penalty card.
b2: not to require or prohibit a lead of a club from South, in which case the
♣10 remains a penalty card and South is free to lead any of his cards at his own choice. However, South must then now lead his his
♣K and North must follow suit with his
♣10 as both these cards are major penalty cards in this situation.
Laws 50-52 apply individually to each defender when both defenders have penalty card(s).
