http://www.afbjj.com/index.php?optio...&id=3&Itemid=5
under competition updates it says
"In the case of Frontal Guillotine,Frontal Neck Crank and Cervical lock (with chokes),
as mentioned in the context of the rules, the referee retains the right to determine
whether, in his or her opinion, the neck is being stretched (leading to possible
cervical damage) or choked.
Where the referee determines that the neck is being stretched, and that possible
cervical damage could occur, the ght shall be imediately stopped and the
competitor applying the submission shall be disqualied."
