its a 6 month deferred imposition. so, 61 days after june 28, his guilty plea will be considered withdrawn, the case will be dismissed and sealed from public view. interesting thing about a deferred imp though is that it does require an admission of guilt.
on the firearms restrictions... under north dakota law, any type of probation (whether supervised or unsupervised) requires that the court order a person not to own or possess firearms absent a finding to the contrary. some courts do it. others, not so much. judge hovey is one who follows the letter of the law on that.
honestly, its just a feel good thing and isn't really enforced unless he were to come across a LEO and be in possession. even then, it might not be enforced strictly. its not like they go to your home and search the darn thing. but, if you were going to comply, it just involves giving them to a relative temporarily. this is over for him in june. so, he will be hunting next fall.
