Article 22 EUMR after Illumina/​Grail: ECJ clarifies when the referral deadline starts

The Court of Jus­ti­ce deli­ver­ed its judgment in Bras­se­rie Natio­na­le and Munho­wen v Com­mis­si­on (C‑572/25 P) on 8 Octo­ber 2026. The ruling cla­ri­fies when the 15-working-day peri­od for an Artic­le 22 EUMR refer­ral starts whe­re no natio­nal mer­ger noti­fi­ca­ti­on is requi­red. As of 9 Octo­ber 2026, the full judgment is available on CURIA in French only. The Court lea­ves the limits estab­lished in Illumina/​Grail int­act and addres­ses a nar­row pro­ce­du­ral issue ari­sing in the excep­tio­nal Luxem­bourg setting.

It con­firms that mere awa­re­ness of a tran­sac­tion by a natio­nal com­pe­ti­ti­on aut­ho­ri­ty is not suf­fi­ci­ent. The dead­line starts only once the aut­ho­ri­ty has actively recei­ved suf­fi­ci­ent infor­ma­ti­on to make a preli­mi­na­ry assess­ment of whe­ther the con­di­ti­ons for an Artic­le 22 refer­ral are met.

The­r­e­fo­re, the prac­ti­cal scope of the judgment is narrow.

A narrow Article 22 issue after Illumina/​Grail

The judgment must be read against Illumina/​Grail. The­re, the Court rejec­ted the Com­mis­si­on’s broa­der inter­pre­ta­ti­on of Artic­le 22 EUMR. A natio­nal com­pe­ti­ti­on aut­ho­ri­ty can­not gene­ral­ly refer a tran­sac­tion which it is not com­pe­tent to review under its own natio­nal mer­ger con­trol rules. Artic­le 22 the­r­e­fo­re does not pro­vi­de a gene­ral mecha­nism for cir­cum­ven­ting natio­nal mer­ger con­trol thresholds.

Refer­ring that, Bras­se­rie Natio­na­le does not qua­li­fy that con­clu­si­on. The case con­cerns Luxem­bourg, which had no natio­nal mer­ger con­trol regime when the tran­sac­tion took place and still has no gene­ral ex-ante mer­ger con­trol regime today. Luxem­bourg is the­r­e­fo­re an excep­tio­nal case.

The Luxem­bourg Com­pe­ti­ti­on Aut­ho­ri­ty is curr­ent­ly deve­lo­ping a struc­tu­red pro­ce­du­re for com­pa­nies to com­mu­ni­ca­te infor­ma­ti­on about tran­sac­tions that could poten­ti­al­ly be refer­red to the Com­mis­si­on under Artic­le 22. The initia­ti­ve is express­ly inten­ded to ope­ra­te pen­ding the intro­duc­tion of natio­nal mer­ger control.

When does the 15-working-day period start?

The Court deci­ded: Whe­re no natio­nal noti­fi­ca­ti­on is requi­red, Artic­le 22(1) EUMR pro­vi­des that a refer­ral request must be made within 15 working days of the con­cen­tra­ti­on being “made known” to the Mem­ber State.

The Court held that mere know­ledge of the exis­tence of the tran­sac­tion is not enough. The­re must be an acti­ve trans­mis­si­on of infor­ma­ti­on that enables the natio­nal aut­ho­ri­ty to car­ry out a preli­mi­na­ry assess­ment of whe­ther the tran­sac­tion may affect trade bet­ween Mem­ber Sta­tes and threa­ten signi­fi­cant­ly to affect com­pe­ti­ti­on in that Mem­ber State.

This com­mu­ni­ca­ti­on is not a for­mal mer­ger noti­fi­ca­ti­on. Nor does Artic­le 22 make such a com­mu­ni­ca­ti­on a pre­re­qui­si­te for a refer­ral. Its rele­van­ce is pro­ce­du­ral: Only suf­fi­ci­ent­ly detail­ed infor­ma­ti­on starts the 15-working-day refer­ral period.

No new referral route below German merger control thresholds

The judgment the­r­e­fo­re does not revi­ve the approach rejec­ted in Illumina/​Grail.

For Ger­man mer­ger con­trol, in par­ti­cu­lar, it does not crea­te a new Artic­le 22 rou­te for tran­sac­tions fal­ling out­side the juris­dic­tion of the Bun­des­kar­tell­amt mere­ly becau­se the Ger­man noti­fi­ca­ti­on thres­holds are not met.

Whe­re a natio­nal mer­ger noti­fi­ca­ti­on is requi­red, Artic­le 22 alre­a­dy links the refer­ral dead­line to that noti­fi­ca­ti­on. Bras­se­rie Natio­na­le cla­ri­fies the much nar­rower alter­na­ti­ve: what starts the clock whe­re no natio­nal fil­ing is requi­red at all.

The judgment is the­r­e­fo­re best unders­tood as a cla­ri­fi­ca­ti­on of the pro­ce­du­ral mecha­nics of Artic­le 22 in an excep­tio­nal set­ting, rather than as an expan­si­on of EU mer­ger con­trol jurisdiction.
