The United Nations Environment Programme is holding a congress next year. The object seems to be to have national legal systems work to the UN's agenda rather than the public's:
The World Congress is aimed at contributing to the Rio+20 process by promoting global consensus among relevant stakeholders such as those engaged in the development of law, Chief Justices and senior judges, Attorneys-General and Public Prosecutors involved in the interpretation and enforcement of law and Auditors-General whose work will focus on governance and accountability issues on the role of law in promoting the goals of sustainable development.
If politicians tried to influence judges there would be an outcry. Why is it OK for the United Nations?
