The first instance court of Gelderland held in X v Lufthansa that the latter’s limitation to objecting to territorial jurisdiction within The Netherlands, rather than to jurisdiction of the Dutch courts as such, amounts to submission under A26 BIa, leaving the Dutch courts to decide on territorial jurisdiction with reference to internal Dutch civil procedure rules (CPR).
The remainder of the judgment then agrees with Lufthansa on the basis of Dutch CPR identifying the defendant’s office or branch as the territorially relevant factor, leaving Gelderland without jurisdiction. The court seemingly rejected itself as forum contractus, holding that CJEU C-204/08 Rehder v Air Baltic does not apply due to the flight in current case not being intra-EU (final destination being Baku). I would have expected the court to consider C-20/21 LOT Polish Airlines, where the final destination equally was outside the EU.
I do not know what claimant argued (forum contractus one assumes, perhaps locus damni per A7(2) BIA?), at any rate it is wrong to hold that a limitation of jurisdictional objection to internal distribution, implies submission per A26 BIa, for those heads of jurisdiction which assign jurisdiction territorially, not just nationally. That includes A7 forum contractus and forum delicti.
