Article 1 of Council Decision 2004/817/EC of 19 November 2004 authorising Germany to apply a measure derogating from Article 17 of Sixth Directive 77/388/EEC on the harmonisation of the laws of the Member States relating to turnover taxes must be interpreted as meaning that it does not apply to a situation in which the goods or services that an undertaking acquires are used, to an extent greater than 90%, for non-economic activities, which fall outside the scope of value added tax.
