In C-548/12 Brogsitter, the CJEU held that the fact that one contracting party brings a civil liability claim against the other is not sufficient to consider that the claim concerns ‘matters relating to a contract’ within the meaning of Article 7(1) Brussels I Recast. That is the case only where the conduct complained of may be considered a breach of contract, which may be established by taking into account the purpose of the contract, which will in principle be the case only where the interpretation of the contract which links the defendant to the applicant is indispensable to establish the lawful or, on the contrary, unlawful nature of the conduct complained of against the former by the latter.
At the end of December, Kokott AG Opined in C-196/15 Granarolo (even now, early April, the English version was not yet available) effectively applying Brogsitter to the case at hand: an action for damages for the abrupt termination of an established business relationship for the supply of goods over several years to a retailer without a framework contract, nor an exclusivity agreement. Ms Kokott (at 17) points out that unlike Brogsitter, there is no forceful link with the contractual arrangements between parties which would be the foundation for jurisdiction on the basis of contractual (non) performance (which there would have been had there been a framework relation between the parties). Rather, the source for a claim between the parties is a statutory provision (it is not specifically identified: however presumable it relates to unfair commercial practices) that existing business relations cannot be abruptly halted without due cause.
Article 7(2) therefore should determine jurisdiction (and Article 4 of course: domicile of the defendant), not Article 7(1).
