establishment only where such site or project continues for a period of more than six months. Paragraph 4 of Article 5 commences with a non obstante clause stating that notwithstanding the preceding provisions of Article 5 the term `permanent establishment’ shall be deemed not to include and there are six clauses in paragraph 4 of which clause (e) would be relevant for case on hand, which states that maintenance of fixed place of business solely for the purpose of advertising, for the supply of information, for scientific research or for other activities which had preparatory or auxiliary character for the enterprise would not fall within the definition of a permanent establishment. Taking note of Article 5 of the agreement with Netherlands, the learned Tribunal examined the facts of the case and found that the activities of the project office of the respondent/assessee in West Bengal was auxiliary in character. The project office was in operation from 26th February, 1999 to 29th July, 1999, that is, for a period of 153 days only, which the Tribunal found, was much less than the period of six months, as stipulated in Article 5(3).
