3. Without prejudice to paragraph 1, national supervisory authorities shall be independent from any air navigation service providers, in organisational, hierarchical and decision-making terms, and shall be either legally or functionally distinct from air navigation service providers. In addition, air navigation service providers shall have no decision-making power over the allocation of the budgets of national supervisory authorities. Provided that such independence is guaranteed, a national supervisory authority may be part of the same national ministry or administration as an air navigation service provider.
