“24. To have all issues of infringement determined by one court gives rise to a greater chance of consistency. It will in many cases reduce the amount of litigation involved and it will mean that only one court, and perhaps in some cases only one judge, need be educated so as to understand the patented technology involved. 25. It appears to me that those considerations apply here. Although it is not strictly necessary to do so, one can see that it makes good commercial sense for the parties to have agreed that rather than have the issue of infringement determined in up to 24 different countries where MedImmune may sell its products, all the issues of infringement should be determined in one court which could effectively become a specialist in determining that issue.”
“But the general rule is clear: where parties have bound themselves by an exclusive jurisdiction clause effect should ordinarily be given to that obligation in the absence of strong reasons for departing from it. Whether a party can show strong reasons, sufficient to displace the other party's prima facie entitlement to enforce the contractual bargain, will depend on all the facts and circumstances of the particular case.”
“The authorities show that the English court may well decline to grant an injunction or a stay, as the case may be, where the interests of parties other than the parties bound by the exclusive jurisdiction clause are involved or grounds of claim not the subject of the clause are part of the relevant dispute so that there is a risk of parallel proceedings and inconsistent decisions.”
“33. Thus Mr Donohue's strong prima facie right to be sued here on claims made by the other parties to the exclusive jurisdiction clause so far as the claims made fall within that clause is matched by the clear prima facie right of the Armco companies to pursue in New York the claims mentioned in the last three paragraphs. The crucial question is whether, on the fact of this case, the Armco companies can show strong reasons why the court should displace Mr Donohue's clear prima facie entitlement. If strong reasons are to be found (and the need for strong reasons is underlined in this case by the potential injustice to Mr Donohue, already noted, if effect is not given to the exclusive jurisdiction clauses) they must lie in the prospect, if an injunction is granted, of litigation between the Armco companies on one side and Mr Donohue and the PCCs on the other continuing partly in England and partly in New York. What weight should be given to that consideration in the circumstances of this case? 34. I am driven to conclude that great weight should be given to it. The Armco companies contend that they were the victims of a fraudulent conspiracy perpetrated by Messrs Donohue, Atkins, Rossi and Stinson. Determination of the truth or falsity of that allegation lies at the heart of the dispute concerning the transfer agreements and the sale and purchase agreement. It will of course be necessary for any court making that determination to consider any contemporary documentation and any undisputed evidence of what was said, done or known. But also, and crucially, it will be necessary for any such court to form a judgment on the honesty and motives of the four alleged conspirators. It would not seem conceivable, on the Armco case, that some of the four were guilty of the nefarious conduct alleged against them and others not. It seems to me plain that in a situation of this kind the interests of justice are best served by the submission of the whole dispute to a single tribunal which is best fitted to make a reliable, comprehensive judgment on all the matters in issue. A procedure which permitted the possibility of different conclusions by different tribunals, perhaps made on different evidence, would in my view run directly counter to the interests of justice.”
