Artikel 27

1. Where a resident of one of the States considers that the actions of one or both of the States result or will result for him in taxation not in accordance with this Convention, he may, notwithstanding the remedies provided by the national laws of those States, present his case to the competent authority of the State of which he is a resident.
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 Convention.
3. The competent authorities of the States shall endeavour to resolve by mutual agreement any difficulties or doubts arising as to the interpretation or application of this Convention. They may also consult together for the elimination of double taxation in cases not provided for in this Convention.
4. The competent authorities of the States may communicate with each other directly for the purpose of reaching an agreement in the sense of the preceding paragraphs.
