The Convention of 27 September 1968 on Jurisdiction and the Enforcement of Judgments in Civil and Commercial Matters, as amended by the Convention of 9 October 1978 on the accession of the Kingdom of Denmark, Ireland and the United Kingdom of Great Britain and Northern Ireland, by the Convention of 25 October 1982 on the accession of the Hellenic Republic and by the Convention of 26 May 1989 on the accession of the Kingdom of Spain and the Portuguese Republic, is to be interpreted as precluding the grant of an injunction whereby a court of a Contracting State prohibits a party to proceedings pending before it from commencing or continuing legal proceedings before a court of another Contracting State, even where that party is acting in bad faith with a view to frustrating the existing proceedings.
