ECJ
27 April 1999 ‘Mietz v Intership Yachting Sneek’ (Case
C-99/96, ECR 1999 p. I-02277) 
The fact that the defendant appears before the court dealing with interim measures in the context of fast procedures intended to grant provisional or protective measures in case of urgency and which do not prejudice the examination of the substance cannot, by itself, suffice to confer on that court, by virtue of Article 18 of the Convention of 27 September 1968, unlimited jurisdiction to order any provisional or protective measure which the court might consider appropriate if it had jurisdiction under the Convention as to the substance of the matter.

1. Article 18 of the 1968 Brussels Convention applies even where the parties have by agreement designated a court which is to have jurisdiction within the meaning of Article 17 of that Convention .
2. Article 18 of the 1968 Brussels Convention must be interpreted as meaning that the rule on jurisdiction which that provision lays down does not apply where the defendant not only contests the court's jurisdiction, but also makes submissions on the substance of the action, provided that if the challenge to jurisdiction is not preliminary to any defence as to the substance it does not occur after the making of the submissions which under national procedural law are considered to be the first defence addressed to the court seised.
Case Law 1968 Brussels Convention
Article 19 of the 1968 Brussels Convention
ECJ 15 November 1983 'Duijnstee v Goderbauer' (Case 288/82, ECR 1983 p. 03663)
1. The 1968 Brussels Convention, which seeks to determine the jurisdiction of the courts of the contracting states in civil matters, must override national provisions which are incompatible with it.
2. Article 19 of that Convention requires the national court to declare of its own motion that it has no jurisdiction whenever it finds that a court of another contracting state has exclusive jurisdiction under Article 16 of this Convention, even in an appeal in cassation where the national rules of procedure limit the court's reviewal to the grounds raised by the parties.
Case Law 1968 Brussels Convention
Article 20 of the 1968 Brussels Convention
Article 57(2)(a) of the 1968 Brussels Convention should be interpreted as meaning that the court of a Contracting State in which a defendant domiciled in another Contracting State is sued may derive its jurisdiction from a specialised convention to which the first State is a party as well and which contains specific rules on jurisdiction, even where the defendant, in the course of the proceedings in question, submits no pleas on the merits and formally contests the jurisdiction of the court seised.
In that connection, although it is true that according to Article 20 of the 1968 Brussels Convention, applicable by virtue of the second sentence of Article 57(2)(a), the court in question is required to declare of its own motion that it has no jurisdiction unless its jurisdiction was derived from the terms of that convention, the jurisdiction of that court must, however, be regarded as derived from the Convention, because Article 57 thereof specifically states that the rules of jurisdiction laid down by specialised conventions are not affected by that convention.
In those circumstances, when verifying of its own motion whether it has jurisdiction with respect to that convention, the court of a Contracting State in which a defendant domiciled in another Contracting State is sued and fails to enter an appearance must take account of the rules of jurisdiction laid down by specialised conventions to which the first Contracting State is also a party.
ECJ 15 July 1982 ‘Pendy Plastic v Pluspunkt’ (Case 228/81, ECR 1982 p. 02723)
The court of the State in which enforcement is sought may, if it considers that the conditions laid down by Article 27(2) of the 1968 Brussels Convention are fulfilled, refuse to grant recognition and enforcement of a judgment even though the court of the State in which the judgment was given regarded it as proven, in accordance with the third paragraph of Article 20 of that Convention in conjunction with Article 15 of the Hague Convention of 15 November 1965, that the defendant, who failed to enter an appearance, had an opportunity to receive service of the document instituting the proceedings in sufficient time to enable him to make arrangements for his defence.
