The future
The Convention on the Future of Europe had a working group on simplification chaired by the former Italian Prime Minister, Giuliano Amato. The group wants a radical reduction in the, currently 32, different ways of making EU decisions.
The EU Constitution has partly followed this proposal by reducing the legal acts to EU laws, EU framework laws, decisions, regulations, recommendations and opinions.
