Disclaimer, If this guy mends fences, farms the land, or helps your family out on a regular basis to secure his hunting spot- Just because you're family, IMO, doesn't give you the ethical rite to "kick" him off his stand.
That's your opinion. If I own anything (which I do) that gives me the ethical right to do whatever I want with it, including kicking someone off or just not letting them hunt. If he had put in his work for this year I would let him continue to hunt this year but I would inform him that next year he's out on his can. Myself or my family would have paid for the right do that
