Table result: 3NT+2(W), N/S -460
E/W play 5-card majors. 1♣ is either (i) natural or (ii) 15-19 balanced with 2+ clubs.
East intended 2♣ to be forcing; West interpreted it as a non-forcing limit raise.
North claims that, had he known that 2♣ was intended to be forcing, he would have passed out 2♣.
The E/W convention card confirms that E/W play 1♣-Pass-2♣ as an inverted raise but does not mention the auction 1♣-overcall-2♣.
TD's Ruling
The Director awarded a score of 80% of minus 150 to the North-South pair, 20% of minus 460.
Basis of TD's Ruling
Having spoken to East and West, he was "convinced" that they did not have an agreement about the meaning of 2♣. This, in addition to the fact that East-West did play 2♣ as forcing if North had passed, was all the information to which North was entitled. In those circumstances North might bid again but would probably pass the weighting assigned to the respective probabilities was that North would pass four times out of five.
Basis of Appeal
East/West appeal, saying that (i) they are not sure what they have done wrong ; (ii) N/S misdefended 3NT to allow it to make 11 tricks and (iii) the TD's adjustment has turned a very good score into a very bad score for them.
