1NT was 15-17 (ahem), 2D was not alerted but was meant to be spades and another suit. The convention card says Asptro.
Neither East nor West said anything about the misunderstanding.
At trick 6, North calls the director and says that there has been misinformation. Director comes over and after making some enquiries, states that 2D should have been explained and that he should be called back at the end of the hand if further rectification is required.
Table result was 2D - 3, NS +150 (which was 100% of the matchpoints for NS). Director comes back and South says that he is happy with the table result.
West calls the director back and says he wishes to appeal the ruling, stating that he doesn't see why he should have to announce to the table that he doesn't have any diamonds and that NS have behaved unethically by stating that there has been misinformation mid hand.
South (the more experienced member of the partnership) tells West that it was obvious to anyone who has been playing the game for more than 5 minutes that he didn't have diamonds.
Director goes off to get an appeals form, during which time West carries on about the unethical statement. South tells West that if he wasn't happy with the director's ruling he has the right to take it to appeals committee if he wanted to. If he wasn't going to do that, he should shut up.
How do you sort this one out?
