for "Ippon". In addition, in the case of a mutual strike, the two flags are extended horizontally. If there is a foul,
the flag should be pointed in the direction of the competitor. To cancel a decision that has already been made,the flag should be crossed at the bottom and spread to the left and right.

If the flag is raised in the heat of the moment, it will be considered invalid if the flag israised in the heat of the moment and a cancellation signal is given.
*Once a decision has been made, it cannot be overturned, even if it is a misjudgment.
