This is the situation: Contract 3NT. West A, K, Q (on trick 3), West (defender) was on lead, East revoked, trick 4, West led the same suit again, now East realized the revoke and correct the revoke. Declarer won trick 4, after that East never win any trick (all tricks were won by West). The contract went down-1, tournament director adjusted the contract made. Was that a correct decision?
