"Since the object of the Convention is not to unify those formalities, which are closely linked to the organization of judicial procedure in the various States, the question as to the moment at which the conditions for definitive seisin for the purposes of Article 21 are met must be appraised and resolved, in the case of each court, according to the rules of its own national law."
"Where proceedings involving the same cause of action and between the same parties are brought in the courts of different Contracting States, any court other than the court first seised shall of its own motion stay its proceedings until such time as the jurisdiction of the court first seised is established. Where the jurisdiction of the court first seised is established, any court other than the court first seised shall decline jurisdiction in favour of that court."
"It may properly be inferred from Article 21, read as a whole, that a court's obligation to decline jurisdiction in favour of another court only comes into existence if it is established that proceedings have been definitively brought before a court in another State involving the same cause of action and between the same parties. Beyond that, Article 21 gives no indication of the nature of the procedural formalities which must be taken into account for the purposes of considering whether or not to recognise the existence of such an effect. In particular, it gives no indication as to the answer to the question whether a lis pendens comes into being upon the receipt by a court of an application or upon service or notification of that application on or to the party concerned."
"the court 'first seised' is the one before which the requirements for proceedings to become definitively pending are first fulfilled, such requirements to be determined in accordance with the national law of each of the courts concerned."
"Next, 'real' is what we may call a trouser-word . It is usually thought, and I daresay usually rightly thought, that what one might call the affirmative use of a term is basic - that, to understand ' x ', we need to know what it is to be x, or to be an x , and that knowing this apprises us of what it is not to be x, not to be an x . But with 'real'...it is the negative use which wears the trousers. That is, a definite sense attaches to the assertion that something is real, a real such-and-such, only in the light of a specific way in which it might be, or might have been, not real. 'A real duck' differs from the simple 'a duck' only in that it is used to exclude various ways of not being a real duck - but a dummy, a toy, a picture, a decoy, &c.; and moreover I don't know just how to take the assertion that it is a real duck unless I know just what, on that particular occasion, the speaker has it in mind to exclude."
"to reinforce the legal protection available to persons established in the Community by, at the same time, allowing the plaintiff easily to identify the court before which he may bring an action and the defendant reasonably to foresee the court before which he may be sued."
"5. 201 At present, in both the Court of Session and the Sheriff Court, there is an administrative check at the time of issuing the warrant to serve an initiating writ (which may be a summons, petition or initial writ) to ascertain whether it discloses adequate grounds of jurisdiction, and any defect will be drawn to the pursuer's attention. This practice can continue after the Convention comes into force. However, it must be understood that in view of Article 18 the clerk of court cannot refuse warrant to serve an initiating writ on grounds of lack of jurisdiction unless it is clear that another court has exclusive jurisdiction under article 19. 5.202 We recommend that the following administrative practice be adopted to implement the first paragraph of article 20:- (a) It should be presumed in practice, where the defender's address stated in the initiating writ is in Scotland, that the defender is domiciled here and that accordingly there is jurisdiciton."
