Wow, court ruled public lands can be used as access by the federal government temporarily. Well, duh. It’s public land for goodness sakes. I agree, if someone raises a stink then build the fence on the north side of their property however, don’t bother issuing a passport as they’ve already declared which side they’re on.
No, it would be called a “convenience fence”. In fact, the entire fence is a conveniece fence.
