177Secondly, in so far as the applicant complains that the Commission did not request a new expert opinion, it should be observed that, according to the case-law, the complaint that the Commission failed to seek assistance from external experts when drafting the contested decision cannot succeed as such, since no provision of the Treaty or of EU legislation imposes any such obligation on the Commission (see, to that effect, judgments of 25 June 1998 in British Airways and Others v Commission, T‑371/94 and T‑394/94, ECR, EU:T:1998:140, paragraph 72, and 16 March 2000 in Astilleros Zamacona v Commission, T‑72/98, ECR, EU:T:2000:79, paragraph 55).
