“An insurer domiciled in a Member State may be sued: (a) in the courts of the Member State in which he is domiciled; (b) in another Member State, in the case of actions brought by the policyholder, the insured or a beneficiary, in the courts for the place where the claimant is domiciled; or (c) if he is a co-insurer, in the courts of a Member State in which proceedings are brought against the leading insurer.”
“15 The rules of jurisdiction should be highly predictable and founded on the principle that jurisdiction is generally based on the defendant’s domicile. Jurisdiction should always be available on this ground save in a few well-defined situations in which the subject-matter of the dispute or the autonomy of the parties warrants a different connecting factor … 16 In addition to the defendant’s domicile, there should be alternative grounds of jurisdiction based on a close connection between the court and the action or in order to facilitate the sound administration of justice. The existence of a close connection should ensure legal certainty and avoid the possibility of the defendant being sued in a court of a Member State which he could not reasonably have foreseen … 18 In relation to insurance, consumer and employment contracts, the weaker party should be protected by rules of jurisdiction more favourable to his interests than the general rules. 21 In the interests of the harmonious administration of justice it is necessary to minimise the possibility of concurrent proceedings and to ensure that irreconcilable judgments will not be given in different Member States. There should be a clear and effective mechanism for resolving cases of lis pendens and related actions …”
“A person domiciled in a Member State may also be sued as a third party in an action on a warranty or guarantee or in any other third-party proceedings, in the court seised of the original proceedings, unless these were instituted solely with the object of removing him from the jurisdiction of the court which would be competent in his case.”
“39 The hearing, in the course of the same proceedings, of both the original action and an action brought by a third party against one of the parties to the original action and closely linked to the original action, is such as to further the above-mentioned objectives in a situation in which an action has been brought by the injured party against the insurer of the person liable for the damage and another insurer, which has already paid the injured party some compensation for his injuries, seeks reimbursement of that compensation from the first-mentioned insurer. 40 If that were not permissible, there would be a risk of two courts, in the same case, arriving at different solutions, whose recognition and enforcement would therefore be uncertain.”
