What is the official rule about an after the fact recognition of an undone mask cord in saber?
Specifically, this scenario: Fencer B on the right makes a direct attack and scores a one light touch. Well after the point has concluded and the touch tallied, bystanders indicate to the ref that Fencer B's mask cord is undone, and insist it was off during the point. It is possible, of course, for the cord to have been dislodged during the action.
The ref, however; did not see any missing cord connection, or call halt. After vigorous discussion, the ref annuls Fencer B's point, and brings both fencers en garde at the place where the last action took place.
Correct call or not?
