It doesnt make sense to create such an organization with existing framework of legal system, Like Orionhunter said. We first need to create a facilitative org that is answerable to the govt, the same govt which in turn can take the bribe and enforce these bodies to lobby for the organization they have been paid for. At that point the whole idea of such a system fails.
The problem of the day is corruption and that is because we have failed to enforce transparency. Once that is done, you can have whatever you want IMHO.
