Correct me if I am wrong, but from my understanding, he does not own the beach itself, but only the road allowing to access it. It is a bit different. It sounds more like a right of way issue.

I guess Vinod's property is the big one on the main road and he also owns the other houses/cabins on Martin's beach road.

Street view with, what I assume the barrier, and the no entrance sign :
