"If the parties, one or more of whom is domiciled in a Member State, have agreed that a court or the courts of a Member State are to have jurisdiction to settle any disputes which have arisen or which may arise in connection with a particular legal relationship, that court or those courts shall have jurisdiction. Such jurisdiction shall be exclusive unless the parties have agreed otherwise. Such an agreement conferring jurisdiction shall be either: (a) in writing or evidenced in writing...."
“In Estasis Salotti di Colzani Aimo et Gianmario Colzani v RÜWA Polstereimaschinen GmbH (Case 24/76) [1976] ECR 1831, 1841, para 7, having pointed out that the effect of conferment of jurisdiction by consent is to exclude the jurisdiction provided for inarticle 5 of the Convention , the Court of Justice continued: ‘In view of the consequences that such an option may have on the position of parties to the action, the requirements set out in article 17 governing the validity of clauses conferring jurisdiction must be strictly construed. By making such validity subject to the existence of an 'agreement' between the parties, article 17 imposes on the court before which the matter is brought the duty of examining, first, whether the clause conferring jurisdiction upon it was in fact the subject of a consensus between the parties, which must be clearly and precisely demonstrated. The purpose of the formal requirements imposed by article 17 is to ensure that the consensus between the parties is in fact established.’ For the reasons given by the Court, the policy of the legislation requires that it is "clearly and precisely demonstrated" that the parties actually agreed to any clause conferring jurisdiction. There is a risk that a jurisdiction clause in a standard form contract put forward by one party might be overlooked by the other and the purpose of article 23(1), as of article 17(1), "is to neutralize the effect of jurisdiction clauses that might pass unnoticed in contracts": Partenreederei ms Tilly Russ and Ernest Russ v NV Haven- & Vervoerbedrijf Nova and NV Geominne Hout (Case 71/83) [1984] ECR 2417, 2435, para 24. As the Court had indicated earlier in the same judgment, at p 2432, para 16, fulfilling the requirements of the article will "guarantee that the other party has actually consented to the clause derogating from the ordinary jurisdiction rules of the Convention." In Coreck Maritime GmbH v Handelsveem BV (Case C-387/98 )[2000] ECR I-9337 , 9371, para 13, the Court summarised its jurisprudence in this way: ‘The Court has held that, by making the validity of a jurisdiction clause subject to the existence of an 'agreement' between the parties,article 17 of the Convention imposes on the court before which the matter is brought the duty of examining first whether the clause conferring jurisdiction upon it was in fact the subject of consensus between the parties, which must be clearly and precisely demonstrated, and that the purpose of the requirements as to form imposed by article 17 is to ensure that consensus between the parties is in fact established….’”
“Their Lordships would respectfully join Lord Steyn in endorsing the approach in the judgment of Waller LJ. Despite the submissions of counsel for the defendants to the contrary, it appears to the Board that, if the standard of "a good arguable case" is properly understood and applied, there is no risk that the effectiveness of the Regulation will be impaired. The rule is that the court must be satisfied, or as satisfied as it can be having regard to the limitations which an interlocutory process imposes, that factors exist which allow the court to take jurisdiction. In practice, what amounts to a "good arguable case" depends on what requires to be shown in any particular situation in order to establish jurisdiction. In the present case, as the case law of the Court of Justice emphasises, in order to establish that the usual rule in article 2(1) is ousted by article 23(1), the claimants must demonstrate "clearly and precisely" that the clause conferring jurisdiction on the court was in fact the subject of consensus between the parties. So, applying the "good arguable case" standard, the claimants must show that they have a much better argument than the defendants that, on the material available at present, the requirements of form in article 23(1) are met and that it can be established, clearly and precisely, that the clause conferring jurisdiction on the court was the subject of consensus between the parties.”
“vi) If there has been no succession, the court seised must ascertain whether the person against whom the jurisdiction clause is invoked actually accepted the jurisdiction clause relied on against him; vii) The court must decide this question by reference to the requirements laid down in the first paragraph of article 23 of the Judgments Regulation, which is also a matter of the law of the Regulation, rather than the national law applicable to the substantive provisions of the contract; viii) The formal requirements of that paragraph are strict; ix) It is for the party relying on the jurisdiction clause to demonstrate clearly and precisely that the formal requirements are met; x) The scope of a valid jurisdiction clause, in the sense of delimiting the disputes that fall within it, is a question of the national law governing the contract.”
"Unless otherwise agreed by the parties, an arbitration agreement which forms or was intended to form part of another agreement (whether or not in writing) shall not be regarded as invalid, non-existent or ineffective because that other agreement is invalid, or did not come into existence or has become ineffective, and it shall for that purpose be treated as a distinct agreement."
“The principle of separability enacted in section 7 means that the invalidity or rescission of the main contract does not necessarily entail the invalidity or rescission of the arbitration agreement. The arbitration agreement must be treated as a "distinct agreement" and can be void or voidable only on grounds which relate directly to the arbitration agreement. Of course there may be cases in which the ground upon which the main agreement is invalid is identical with the ground upon which the arbitration agreement is invalid. For example, if the main agreement and the arbitration agreement are contained in the same document and one of the parties claims that he never agreed to anything in the document and that his signature was forged, that will be an attack on the validity of the arbitration agreement. But the ground of attack is not that the main agreement was invalid. It is that the signature to the arbitration agreement, as a "distinct agreement", was forged. Similarly, if a party alleges that someone who purported to sign as agent on his behalf had no authority whatever to conclude any agreement on his behalf, that is an attack on both the main agreement and the arbitration agreement.”
“ I do not propose to analyse these and other such cases any further because in my opinion the distinctions which they make reflect no credit upon English commercial law. It may be a great disappointment to the judges who explained so carefully the effects of the various linguistic nuances if they could learn that the draftsman of so widely used a standard form as Shelltime 4 obviously regarded the expressions "arising under this charter" in clause 41(b) and "arisen out of this charter" in clause 41(c)(1)(a)(i) as mutually interchangeable. So I applaud the opinion expressed by Longmore LJ in the Court of Appeal (at paragraph 17) that the time has come to draw a line under the authorities to date and make a fresh start.”
