61 U preostalom dijelu, u mjeri u kojoj se argumenti izneseni u točkama 50. do 52. ove presude temelje na pogrešci koja se tiče prava u pogledu ocjene pitanja predstavlja li MasterCard udruženje poduzetnika, treba istaknuti da – suprotno onomu što tvrdi Komisija – ne stoji tvrdnja da žalitelji u osnovi samo dovode u pitanje ocjenu činjenica iz prvostupanjskog postupka, već oni u bitnom navode pravna pitanja koja su u žalbenom postupku dopuštena.
61 As to the remainder, in so far as the arguments set out in paragraphs 50 to 52 of the present judgment allege an error of law with regard to the assessment of the question whether MasterCard is an association of undertakings, it should be noted that, contrary to the Commission’s contention, the appellants are not, in essence, merely challenging the assessment of the facts made at first instance, but are relying, for the main part, on questions of law which are admissible at the appeal stage.EurLex-2 EurLex-2
