(1) The competent authorities of the Contracting States shall exchange such information (being information available under the respective taxation laws of the Contracting States) as is necessary for carrying out the provisions of this Convention or for the prevention of fraud or the administration of statutory provisions against legal avoidance in relation to the taxes which are the subject of this Convention. Any information so exchanged shall be treated as secret but may be disclosed to persons (including a court or administrative body) concerned with the assessment, collection, enforcement or prosecution in respect of taxes which are the subject of this Convention. No information shall be exchanged which would disclose any trade, business, industrial or professional secret or any trade process.
(2) Each of the Contracting States will endeavour to collect on behalf of the other Contracting State such amounts as may be necessary to ensure that relief granted by this Convention from taxation imposed by such other Contracting State does not enure to the benefit of persons not entitled thereto. The United Kingdom will be regarded as fulfilling this obligation by the continuation of its existing arrangements for ensuring that relief from taxation imposed by the laws of the United States does not enure to the benefits of persons not entitled thereto.
(3) Paragraph (2) of this Article shall not impose upon either of the Contracting States the obligation to carry out administrative measures which are of a different nature from those used in the collection of its own tax, or which would be contrary to its sovereignty, security or public policy. In determining the administrative measures to be carried out, each Contracting State may take into account the administrative measures and practices of the other Contracting State in recovering taxes on behalf of the first-mentioned Contracting State.
(4) The competent authorities of the Contracting States shall consult with each other for the purpose of co-operating and advising in respect of any action to be taken in implementing this Article.
