Article 63U.K.Procedure for recourse
1.The validity of the payment made by the carrier exercising a right of recourse pursuant to Article 62 may not be disputed by the carrier against whom the right to recourse is exercised, when compensation has been determined by a court or tribunal and when the latter carrier, duly served with notice of the proceedings, has been afforded an opportunity to intervene in the proceedings. The court or tribunal seized of the principal action shall determine what time shall be allowed for such notification of the proceedings and for intervention in the proceedings.
2.A carrier exercising his right of recourse must present his claim in one and the same proceedings against all the carriers with whom he has not reached a settlement, failing which he shall lose his right of recourse in the case of those against whom he has not taken proceedings.
3.The court or tribunal shall give its decision in one and the same judgment on all recourse claims brought before it.
4.The carrier wishing to enforce his right of recourse may bring his action in the courts or tribunals of the State on the territory of which one of the carriers participating in the carriage has his principal place of business, or the branch or agency which concluded the contract of carriage.
5.When the action must be brought against several carriers, the plaintiff carrier shall be entitled to choose the court or tribunal in which he will bring the proceedings from among those having competence pursuant to paragraph 4.
6.Recourse proceedings may not be joined with proceedings for compensation taken by the person entitled under the contract of carriage.
