“The following courts of a Member State shall have exclusive jurisdiction, regardless of the domicile of the parties: (1) … (2) in proceedings which have as their object the validity of the constitution, the nullity or the dissolution of companies or other legal persons or associations of natural or legal persons, or the validity of the decisions of their organs, the courts of the Member State in which the company, legal person or association has its seat. In order to determine that seat, the court shall apply its rules of private international law; (3) in proceedings which have as their object the validity of entries in public registers, the courts of the Member State in which the register is kept; (4) … (5) …”
“in a dispute of a contractual nature, questions relating to the contract's validity, interpretation or enforceability are at the heart of the dispute and form its subject-matter. Any question concerning the validity of the decision to conclude the contract, taken previously by the organs of one of the companies party to it, must be considered ancillary. While it may form part of the analysis required to be carried out in that regard, it nevertheless does not constitute the sole, or even the principal, subject of the analysis.”
“The appellants submit that art. 16(2) governs all questions which are concerned, with the internal management of a company, and that this extends to all disputes which arise out of the relationship between the company and its officers or shareholders or between its shareholders and officers, and possibly even between its shareholders inter se. This submission is far too wide. Whether an action falls within art. 16(2) depends upon its subject matter the nature of the dispute not upon the relationship between the parties. A claim by an officer of a company for wrongful dismissal, for example, does not fail within the article, though a claim that the decision to dismiss him had been taken by a meeting of the board which was inquorate would do so.”
“In other words, in relation to a claim based on a contract and brought in England pursuant to an exclusive jurisdiction clause in which an ultra vires defence was advanced, which was inextricably bound up with and hence ancillary to the underlying claim, a narrow interpretation of article 22(2) meant that the ultra vires defence did not have the effect of pulling the whole proceedings or any part thereof into the exclusive jurisdiction of the German courts. In that context it could not be said that the ‘principal subject matter’ of the proceedings comprised ‘the validity of the decisions of [BVG’s] organs’ as would be required if article 22(2) was to have any application (para 44 of the judgment).”
