(1) The competent authorities of the Contracting States shall exchange such information as is foreseeably relevant for carrying out the provisions of this Convention or to the administration or enforcement of the domestic laws concerning taxes of every kind and description imposed on behalf of a Contracting State, a "Land" or of a political subdivision or local authority of a Contracting State or a "Land", insofar as the taxation thereunder is not contrary to the Convention. The exchange of information is not restricted by Articles 1 and 2.

(2) Any information received under paragraph (1) by a Contracting State shall be treated as secret in the same manner as information obtained under the domestic laws of that State and shall be disclosed only to persons or authorities (including courts and administrative bodies) concerned with the assessment or collection of, the enforcement or prosecution in respect of, the determination of appeals in relation to the taxes referred to in paragraph (1), or the oversight of the above. Such persons or authorities shall use the information only for such purposes. They may disclose the information in public court proceedings or in judicial decisions. Notwithstanding the foregoing provisions, the information may be used for other purposes, if under the law of both States it may be used for these other purposes and the competent authority of the supplying State authorises this use.

(3) The Contracting States may release to the arbitration board, established under the provisions of paragraph (5) of Article 25, such information as is necessary for carrying out the arbitration procedure. The members of the arbitration board shall be subject to the limitations on disclosure described in paragraph (2) of this Article with respect to any information so released.

(4) In no case shall the provisions of the previous paragraphs be construed so as to impose on a Contracting State the obligation:

• (a) to carry out administrative measures at variance with the laws and administrative practice of that or of the other Contracting State;
• (b) to supply information which is not obtainable under the laws or in the normal course of the administration of that or of the other Contracting State;
• (c) to supply information which would disclose any trade, business, industrial, commercial or professional secret or trade process, or information the disclosure of which would be contrary to public policy (ordre public).

(5) If information is requested by a Contracting State in accordance with this Article, the other Contracting State shall use its information gathering measures to obtain the requested information, even though that other State may not need such information for its own tax purposes. The obligation contained in the preceding sentence is subject to the limitations of paragraph (4) but in no case shall such limitations be construed to permit a Contracting State to decline to supply information solely because it has no domestic interest in such information.

(6) In no case shall the provisions of paragraph (4) be construed to permit a Contracting State to decline to supply information solely because the information is held by a bank, other financial institution, nominee or person acting in an agency or a fiduciary capacity or because it relates to ownership interests in a person.
