The lead was a ♥ wich ended in too many overtricks, West called director and argued nobody alerted 4♥ as splinter, and if alerted the fact eh failed to double it might induce his partner to make a better lead.
North argued that he wasn't sure of the 4♥ meaning, and only because of his ♥ holding, he deduced the right bid. And had he got singleton ♥ he would had passed. And he didn't know he had to alert opponents from the deductions he made based on his own cards. North-South ain't a regular partnership, they had agreed splinters, but didn't talk about 1♠-4♥ sequence, (passed hand even less).
Director ruled that north had made a fult on the alerting procedure and sanctioned with 10% of the board.
Do you think everything right?
