None of those documents envisaged the referral mechanism as a "corrective mechanism" that would allow referral of any concentration falling below the EUMR thresholds, irrespective of whether that concentration fell within the national merger control system of the Member State making the request. The ECJ next concluded that all the factors that the GC had considered as part of its "contextual interpretation" were inconclusive. By contrast, siding with the interpretation advocated by Illumina and Grail, the ECJ highlighted that the replacement of a national authority by the EC under Article 22 EUMR presupposes that the authority responsible domestically for the ex-ante control of concentrations has jurisdiction to review the referred concentration, in particular because the transaction meets the applicable national thresholds. The ECJ's ruling also nullifies the €432 million fine imposed on Illumina by the EC for gun jumping, a financial penalty that had been another point of contention in the case.
