Now the law. Annulment proceedings can be understood as a « procès fait à un acte ». EU law does not follow the adversarial model of litigation of anglo-american legal systems. « We » is inappropriate 2/n

I mean every hyperbolic word here => latest convo of @LeConcurrential w/ Bill Kovacic is gold mine of antitrust wisdom leconcurrentialiste.com/a-conversation… 1/n The requirements of practice makes antitrust laws converge toward rebuttable presumptions, quasi rules, and structured standards 2/n
