I dont know where this 1" thing is coming from.Other than on branch antlers.It says on page 25 of the regs.. Any buck:
Any deer with visible antlers may be taken.(fawns illegal)

I think your body got screwed.He should have taken the pamphlet in with him.I think I would try to get in to see the prosecuting atty that handled the case,or even the judge.Show them the regs.and see about getting the decision reversed.
