Not really. You want to allow an uninterested NPO to file on behalf of a person in direct conflict with their own rights and against their best interests. How is that not an abuse of the legal system? How would you feel if you found out your parents had left you a nice house, but I decided to screw up your claim of title by intervening on behalf of some random guy they allowed to stay on the property sixty years ago? Not nice huh?
Yes really. I propose that arbitrary solution to this specific problem fully aware that it has potential to be exploited in other scenarios. The thing I really want that exists out side of my arbitrary comment is to prevent people in positions of power from abusing the legal system. Two separate concepts entirely.
