However, judgments given after the date of entry into force of this Convention between the State of origin and the State addressed in proceedings instituted before that date shall be recognized and enforced in accordance with the provisions of Title III if jurisdiction was founded upon rules which accorded with those provided for either in Title II of this Convention or in a convention concluded between the State of origin and the State addressed which was in force when the proceedings were instituted. If the parties to a dispute concerning a contract had agreed in writing before 1 June 1988 for Ireland or before 1 January 1987 for the United Kingdom that the contract was to be governed by the law of Ireland or of a part of the United Kingdom, the courts of Ireland or of that part of the United Kingdom shall retain the right to exercise jurisdiction in the dispute. For a period of three years from 1 November 1986 for Denmark and from 1 June 1988 for Ireland, jurisdiction in maritime matters shall be determined in these States not only in accordance with the provisions of Title II, but also in accordance with the provisions of paragraphs 1 to 6 following. However, upon the entry into force of the International Convention relating to the arrest of sea-going ships, signed at Brussels on 10 May 1952, for one of these States, those provisions shall cease to have effect for that State.
