Article 39 — Rights having priority without registration

1. A Contracting State may at any time, in a declaration deposited with the Depositary of the Protocol declare, generally or specifically:
(a) those categories of non-consensual right or interest (other than a right or interest to which Article 40 applies) which under that State's law have priority over an interest in an object equivalent to that of the holder of a registered international interest and which shall have priority over a registered international interest, whether in or outside insolvency proceedings; and
(b) that nothing in this Convention shall affect the right of a State or State entity, intergovernmental organisation or other private provider of public services to arrest or detain an object under the laws of that State for payment of amounts owed to such entity, organisation or provider directly relating to those services in respect of that object or another object.
2. A declaration made under the preceding paragraph may be expressed to cover categories that are created after the deposit of that declaration.
3. A non-consensual right or interest has priority over an international interest if and only if the former is of a category covered by a declaration deposited prior to the registration of the international interest.
4. Notwithstanding the preceding paragraph, a Contracting State may, at the time of ratification, acceptance, approval of, or accession to the Protocol, declare that a right or interest of a category covered by a declaration made under sub-paragraph (a) of paragraph 1 shall have priority over an international interest registered prior to the date of such ratification, acceptance, approval or accession.
