c) to supply information which is not obtainable under its own laws or its administrative practice or under the laws of the applicant State or its administrative practice;

The obligation contained in the preceding sentence is subject to the limitations contained in this Convention, but in no case shall such limitations, including in particular those of paragraphs 1 and 2, be construed to permit a requested State to decline to supply information solely because it has no domestic interest in such information.
4. In no case shall the provisions of this Convention, including in particular those of paragraphs 1 and 2, be construed to permit a requested 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.

1. Any information obtained by a Party under this Convention shall be treated as secret and protected in the same manner as information obtained under the domestic law of that Party and, to the extent needed to ensure the necessary level of protection of personal data, in accordance with the safeguards which may be specified by the supplying Party as required under its domestic law.
