The "Alaskan Bush People" just got smacked down by a judge who made one thing clear -- if you steal from Alaska ... you're gonna do jail time.
Billy Brown -- the dad on the popular Discovery Channel show -- and his son Joshua Brown thought they'd struck a sweet plea deal. As we reported ... they copped to lying on their annual Alaskan oil refund docs and essentially stealing $8,000 from the state. The deal called for them to pay back the money, but dodge jail.
Not soooo fast -- on Thursday the judge in the case rejected that deal and said they deserve jail time for jacking oil funds from honest Alaskans.
The Browns -- who phoned in to the hearing -- and prosecutors will have to go back to the drawing board.
