Our Playing Director made a ruling relating to Law 25, which I suspect is in error. On board 4 (all vul dealer:W) the bidding started: No 1S No 1NT No 2D 2H At this point South was not completely alert and failed to notice East's 2H bid and passed. West also passed. When South awoke (who, how or what wakened him is unclear) he wished to bid, and his partner (The playing TD) allowed him to replace his bid and allowed West's bid to be withdrawn and the auction continued as follows: 3D No 3H No 4D No 5D 3H was alerted as showing a control. The contract made +1, and the opponents felt aggrieved. I am not sure the conditions of Law 25A1 have been met, and indeed, 25A2 seems to cover the circumstances under "...loss of concentration". I feel the director erred, and 5D should not be allowed. Suggestions for any correction welcomed N AK952,A,KT82,A32. E Q86, KQJ876, 96, T5 S 73, 753, A7543, K97 W JT4, 942, QJ, QJ854
