54In the complaint lodged on 24 November 1989 the applicant alleged that the conduct of PMU/PMI and DSV was incompatible with both Article 85 and Article 86 of the Treaty. The complaint was thus also based on Article 86 of the Treaty as is evident, moreover, from the letters referred to above which were written by the applicant to the Commission after its complaint had been submitted, in particular the letter dated 4 February 1991 in which it formally requested the Commission to define its position on the complaint with regard to Article 86 of the Treaty.
