§
ARTICLE 26.—(1) The competent authorities of the Contracting States shall exchange such information as is necessary for the carrying out of this Convention or for the prevention of fraud or for the administration of the domestic laws of the Contracting States concerning taxes covered by this Convention insofar as the taxation thereunder is in accordance with this Convention. Any information so exchanged shall be treated as secret and shall not be disclosed to any persons other than persons (including a Court or administrative body) concerned with the assessment or collection of, or prosecution in respect of, or the determination of appeals in relation to, the taxes which are the subject of the Convention. (2) In no case shall the provisions of paragraph (1) of this Article be construed so as to impose on the competent authority of either Contracting State the obligation: (a)to carry out administrative measures at variance with the laws or administrative practice prevailing in either Contracting State; (b)to supply particulars which are not obtainable under the laws or in the normal course of the administration of that or the other Contracting State; (c)to supply information which would disclose any business, trade, industrial, commercial or professional secret or trade process, or information, the disclosure of which would be contrary to public policy.
