Article 5(7)(a) of Sixth Council Directive must be interpreted as applying to a situation, such as that at issue in the main proceedings, in which a municipality takes first occupation of a building which it has had built on its own land and of which it intends to use 94% of the area for its activities as a public authority and 6% of that area for its activities as a taxable person, including 1% for exempt activities in respect of which no right to deduct VAT exists. However, the subsequent use of the building for the activities of the municipality may give rise to a right to deduct the tax paid in respect of the application provided for by that provision only in the proportion corresponding to its use for the purposes of the taxable transactions, pursuant to Article 17(5) of that directive.
