L 328/4 Official Journal of the European Communities 13.12.2001 (Acts whose publication is obligatory) COUNCIL REGULATION (EC) No 2424/2001 of 6 December 2001 on the development of the second generation Schengen Information System (SIS II) THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty establishing the European Community, and in particular Article 66 thereof, Having regard to the initiative of the Kingdom of Belgium and the Kingdom of Sweden ('), Having regard to the opinion of the European Parliament (%), Whereas: 1) The Schengen Information System, set up pursuant to the provisions of Title IV of the Convention of 1990 implementing the Schengen Agreement of 14 June 1985 on the gradual abolition of checks at common borders, hereinafter referred to as ‘the 1990 Schengen Conven- tion’, constitutes an essential tool for the application of the provisions of the Schengen acquis as integrated into the framework of the European Union. The Schengen Information System in its current form has the capacity to service no more than 18 partici- pating States. It is at present operational for 13 Member States and 2 other States (Iceland and Norway) and is intended to become operational for the United Kingdom and Ireland in the foreseeable future. It has, however, not been constructed so as to service the increased number of Member States of the European Union after its enlargement. For this reason, and in order to benefit from the latest developments in the field of information technology and to allow for the introduction of new functions, it is necessary to develop a new, second generation Schengen Information System (SIS II), as already acknowledged in Decision SCH/Com-ex (97) 24 of the Executive Committee of 7 October 1997 (). The expenditure involved in the development of SIS II is to be charged to the budget of the European Union in accordance with the Council conclusions to that effect of 29 May 2001. This Regulation constitutes, together with Council Decision 2001/886/JHA of 6 December 2001 on the development of the second generation Schengen () O] C 183, 29.6.2001, p. 12.

Information System (SIS II) (¥, the required legislative basis to allow for the inclusion in the budget of the Union of the necessary appropriations for the develop- ment of SIS II and the execution of that part of the budget. The legislative basis consists of two parts: this Regula- tion based on Article 66 of the Treaty establishing the European Community and a Council Decision based on Article 30(1)(a) and (b), Article 31(a) and (b) and Article 34(2)(c) of the Treaty on European Union. The reason for this is that, as set out in Article 92 of the 1990 Schengen Convention, the Schengen Information System is to enable the authorities designated by the Member States, by means of an automated search procedure, to have access to alerts on persons and property for the purposes of border checks and other police and customs checks carried out within the country in accordance with national law, as well as for the purposes of issuing visas, residence permits and the administration of legisla- tion on aliens in the context of the application of the provisions of the Schengen acquis relating to the move- ment of persons. The fact that the legislative basis required for allowing the development of SIS II to be financed by the Union budget consists of two separate instruments does not affect the principle that the Schengen Information System constitutes, and should continue to constitute, one single, integrated, information system and that SIS II must be developed as such. This Regulation is without prejudice to the adoption in future of the necessary legislation describing in detail the operation and use of SIS II, such as, but not limited to, rules defining the categories of data to be entered into the system, the purposes for which they are to be entered and the criteria for their entry, rules concerning the content of SIS records, including responsibility for their correctness, rules on the duration of alerts, inter- linking of alerts and compatibility between alerts, rules on access to SIS data and rules on the protection of personal data and their control.
