If he had phoned the police and explained the situation (A wounded deer), then the chances of him being prosecuted are next to nothing. Please don't muddy the waters Heym. It would be reasonable to believe that permission would have been granted etc! This forum is here to help not hinder genuine law abiding members of our community. If we had to actually obtain permission then very few RTAs would ever be attended by ourselves and deer would be left to die in agony. The law is there to help and not too many rural land owners would ever refuse permission.
Spot on Dexter,
For anyone involved in HD, make sure that you don't leave your self open to any liability or prosecution issues
