West opens 1C...north overcalls 1D...east bids 1NT...south passes...west passes...north bids 2S...passed out. North's actual shape is 4S,1H, 3 little diamonds, 5 clubs, and has 12HCP. E/W assume north has 5D and 4S, with 4 cards in H and C, has "reversed" showing substantial HCP, pass the hand out and defend accordingly. Director was called during play as it became apparent that N only had 3D. Club director ruled that because S had passed on 2 occasions and therefore was not influenced by N bidding, N had bid legitimately, and no disclosure was necessary. Whether the contract makes or not, does north have a duty of disclosure of his D holding, before play commences?
