Sorted hands
Suppose as a TD you get called to the table. The player (dealer) who called you asks to speak with you away from the table and, on doing so, explains that he received their hand already suited. (In this case 5 diamonds the AK and the Ace of hearts on an otherwise balanced hand.) - (If he explains it at the table there is obvious UI considerations)
You dig out Law 16A - find that the information is not authorised (it arose from an irregularity at the previous table -cards not shuffled after a deal) - so therefore is presumably Extraneous. 16D
How do you proceed?
a) Board is unplayable: award 60-60.
b) Dealer is told to proceed as if the hand was not sorted. Now comes the problem. If Dealer makes use of the information (which he can) and e.g.
i) Passes as he suspects the hand will belong to the opponents in a major and hopes to gain. It turns out that this is the winning action.
ii) Bids 1NT as he suspects partner has 10 or so points opposite and knows 1NT will be passed out. It turns out that this is the winning action.
iii) Opens one of the minor, finds partner with a fit and makes three: this is the winning action.
It would seem that the TD must award an adjusted score - in other words the player has no winning option.
Comments
This does seem short of the degree of information that makes a board unplayable. I think if dealer makes their normal opening bid with a balanced hand they're not using the information, some unusual opening bid might be.
I'm not sure that knowing (assuming) the previous player and everyone else at the table passed this hand tells you much. You don't know if it was good or bad for them that they did so.
I'd say that it was just as likely that the player at the previous table had sorted his cards after the play in order to show to their partner - "Well, how would you have bid with this hand?" - and then forgot to shuffle.
