Can choice of court made in underlying documentation in the context of a tender, for which Hőszig entered a winning bid, be considered valid under Article 23 of the Brussels I Regulation (now: Article 25 Brussels I Recast)? Yes, the Court said, with explicit reference to the AG. Crucial point in the consideration is whether per Case 24/76 Colzani an explicit reference to the choice has been made, reference which can be controlled by a party applying normal diligence and where it is established that the general conditions containing the jurisdiction clause was actually communicated to the other contracting party (at 40 in Hoszig). This was so in the case at issue. The court points out that Article 23 (and now Article 25) includes mostly formal requirements (expression of consent, see the references in my posting on the AG’s Opinion) and only one substantial requirement (choice of court needs to relate to an identified legal relationship between the parties). The remainder of discussion on the substantive requirements with respect to the choice of court agreement, is subject to the lex causae of that separate choice of court agreement (exactly why the current Regulation now includes the lex fori prorogati rule; Szpunar AG’s discussion of this clause however was not required to settle the issue and therefore the Court does not look into it).
‘(T)he Paris Courts [have exclusive and final jurisdiction]’ is sufficient for the CJEU to determine the choice of court with precision: it is perfectly acceptable that it will subsequently be French civil procedure laws that will determine precisely which court will have jurisdiction.
A sensible judgment following clear Opinion of the Advocate General, together further completing the choice of court provisions of Brussels I.
