NS are inexperienced young players while EW are veterans. After the 5♣ by North, East asked what is the meaning of 5♣. South said that this shows high card in ♣. No further question was asked. After the end of auction and before East made his lead, North voluntarily corrected his pd's explanation and said that 4♣ is splinter and 5♣ shows void. Now East called director at this point (before making any lead). He told director all the facts and both sides agreed. East asked whether he could change his bid after 6♥ since he was misinformed. Director, after checking Law 21, decided that it was too late for East to change his bid after his pd has bid the final pass. He told East to continue the board and informed him again if East thought that he was damaged by the Misinformation. The board finished quickly with 6♥+1. East called director again and said that he will bid 7♣ after 6♥ if given the correct information. Director, taken into consideration of his call before, decided that EW was damaged and adjusted the score to 7♣X -4.
Do you agree with the director's rulings?
