Article 2
1. The provisions of the Schengen acquis relating to the SIS shall apply, according to the procedure referred to in Article 1, as from 1 January 2001. To this end, the SIS will be loaded with real data by the Nordic States which, like the Member States in respect of which the Schengen acquis has already been implemented, will be able to use such data, subject to the provisions of paragraph 3. This application shall not hinder cooperation within the Nordic passport union. 2. The provisions referred to in the first paragraph shall be set out in the Annex. 3. Until the date mentioned in Article 1, the Nordic States: (a) shall not be obliged to refuse entry to their territory or to expel nationals of third States for whom an SIS alert has been issued by another Member State for the purposes of refusing entry and who come direct from a Member State in respect of which the Schengen acquis provisions already apply; (b) may admit to their territory nationals of third States for whom an SIS alert has been issued by another Member State for the purposes of refusing entry, where a Nordic State has decided to grant a visa or another residence permit to such nationals; (c) shall refrain from entering the data covered by Article 96 of the Convention implementing the Schengen Agreement.
