Article 16(1)(a) of the Convention of 27 September 1968 on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters, as amended most recently by the Convention of 29 November 1996 on the Accession of the Republic of Austria, the Republic of Finland and the Kingdom of Sweden, must be interpreted as meaning that an action which, like that brought under Paragraph 364(2) of the Allgemeines bürgerliches Gesetzbuch (Austrian Civil Code) in the main proceedings, seeks to prevent a nuisance affecting or likely to affect land belonging to the applicant, caused by ionising radiation emanating from a nuclear power station situated on the territory of a neighbouring State to that in which the land is situated, does not fall within the scope of that provision.
