The videos that Sowpoke Slim linked, above, add an attorney's interpretation to the WyoFile original reports of the issue. But that Eastern attorney doesn't seem to recognize the westerner's perspective that dominates the comments on YouTube below the video, and I think this is the essence of the issue:
This landowner, who is said to use lawsuits generously in his Wyoming real estate ventures, names $7m as his damages because feels the value of his 28,000 acre hunting preserve is diminished by losing his exclusive right to control access into the 6,000 acres of public land within his outer perimeter. So now he can only claim he controls 22,000 acres, and this diminishes what he thought was the overall value of his ranch.
His is a nonsense assertion. He never owned the 6,000 acres so he has lost nothing by the court re-affirming the public's right to use the public land.
