Artikel 27

1. Where a person considers that the actions of one or both of the two States result or will result for him in taxation not in accordance with the provisions of this Agreement, he may, irrespective of the remedies provided by the domestic law of those States, present his case to the competent authority of the State of which he is a resident or, if his case comes under paragraph 1 of Article 26, to that of the State of which he is a national. The case must be presented within three years from the first notification of the action resulting in taxation not in accordance with the provisions of the Agreement.
2. The competent authority shall endeavour, if the objection appears to it to be justified and if it is not itself able to arrive at an appropriate solution, to resolve the case by mutual agreement with the competent authority of the other State, with a view to the avoidance of taxation not in accordance with this Agreement.
3. The competent authorities of the two States shall endeavour to resolve by mutual agreement any difficulties or doubts arising as to the interpretation or application of this Agreement. They may also consult together for the elimination of double taxation in cases not provided for in this Agreement.
4. The competent authorities of the two States may communicate with each other directly for the purpose of reaching an agreement in the sense of the preceding paragraphs.
