CONFLICT OF INTEREST: I am related to one of the players contesting the final, but who wasn't at the table where the issue arose.
DISCLAIMER: The "facts" reported here are as they were told to me by a member of one of the appealing teams and, accordingly, may not represent exactly what is presented to the appeals committee.
The table result was 3♥x-2 for -300.
It transpires that E-W have no agreement as to the meaning of the double; indeed East was playing as a substitute due an illness of West's regular partner. E-W do, however, have some partnership experience together.
N-S represent that they have an agreement that after 2♦ is doubled, pass indicates a willingness to play in 2♦x and redouble asks partner to bid their better Major.
South represents that having been told that his RHO has a penalty double of 2♦, North must be 5512 or 5503 which will make 3♣ the best spot for N-S. South also argues that had he been given the same explanation as was given on the other side of the screen, 2♦ becomes a viable option and he would therefore pass and let North sit the double if he has something in ♦.
The TD adjusted the result to 2♥x-1 for -100, but I've not been told what the rationale for that ruling was.
Both sides have appealed the ruling. N-S seeking an adjustment to 2♦x= and E-W seeking a reinstatement of the table result.
I have no other information about the hand.
