Among the old laws of the Channel Islands is the old Norman custom of the clameur de haro. Using this legal device, a person can obtain immediate cessation of any action he considers to be an infringement of his rights
At the scene, he must, in front of witnesses, recite the Lord's Prayer in French and cry out "Haro, Haro, Haro! À mon aide mon Prince, on me fait tort!" ("*Haro, Haro, Haro! To my aid, my Prince! I am being wronged!"). It should then be registered with the Greffe Office within 24 hours. All actions against the person must then cease until the matter is heard by the Court.
Don't mind me, I'm just off to learn the Lord's Prayer in Norman French and buy a ticket to the Channel Islands. Not sure who I'm going to use this new superpower against first but I can think of several good candidates!
