Article VI

The Contracting States shall lend assistance to each other in the collection of revenue claims. This assistance is not restricted by Articles 1 and 2. The competent authorities of the Contracting States may by mutual agreement settle the mode of application of this Article.

The term ‘revenue claim’ as used in this Article means an amount owed in respect of taxes of every kind and description imposed on behalf of the Contracting States, or of their political subdivisions or local authorities, insofar as the taxation thereunder is not contrary to this Convention or any other instrument to which the Contracting States are parties, as well as interest, administrative penalties and costs of collection or conservancy related to such amount.

The provisions of this Article shall apply only to a revenue claim that forms the subject of an instrument permitting enforcement in the applicant State and, unless otherwise agreed between the competent authorities, that is not contested. However, where the claim relates to a liability to tax of a person that is not a resident of the applicant State, this Article shall only apply, unless otherwise agreed between the competent authorities, where the claim may no longer be contested. The revenue claim shall be collected by that other State in accordance with the provisions of its laws applicable to the enforcement and collection of its own taxes as if the revenue claim were a revenue claim of that other State.

When a revenue claim of a Contracting State is a claim in respect of which that State may, under its law, take measures of conservancy with a view to ensure its collection, that revenue claim shall, at the request of the competent authority of that State, be accepted for purposes of taking measures of conservancy by the competent authority of the other Contracting State. That other State shall take measures of conservancy in respect of that revenue claim in accordance with the provisions of its laws as if the revenue claim were a revenue claim of that other State even if, at the time when such measures are applied, the revenue claim is not enforceable in the first-mentioned State or is owed by a person who has a right to prevent its collection.

Notwithstanding the provisions of paragraphs 3 and 4, a revenue claim accepted by a Contracting State for purposes of paragraph 3 or 4 shall not, in that State, be subject to the time limits or accorded any priority applicable to a revenue claim under the laws of that State by reason of its nature as such and, unless otherwise agreed between the competent authorities, shall not lead to imprisonment of the debtor in respect of the debt. In addition, a revenue claim accepted by a Contracting State for the purposes of paragraph 3 or 4 shall not, in that State, have any priority applicable to that revenue claim under the laws of the other Contracting State.

Proceedings with respect to the existence, validity or the amount of a revenue claim of a Contracting State shall not be brought before the courts or administrative bodies of the other Contracting State.

Where, at any time after a request has been made by a Contracting State under paragraph 3 or 4 and before the other Contracting State has collected and remitted the relevant revenue claim to the first-mentioned State, the relevant revenue claim ceases to be:

In no case shall the provisions of this Article be construed so as to impose on a Contracting State the obligation:
