7.8.2007 Official Journal of the European Union L 205/63 11 (Acts adopted under the EU Treaty) ACTS ADOPTED UNDER TITLE VI OF THE EU TREATY COUNCIL DECISION 2007/533[JHA of 12 June 2007 on the establishment, operation and use of the second generation Schengen Information System (SIS 1) THE COUNCIL OF THE EUROPEAN UNION, Having regard to the Treaty on European Union, and in particu- lar Articles 30(1)(a) and (b), 31(1)(a) and (b) and 34(2)(c) thereof, Having regard to the proposal from the Commission, Having regard to the opinion of the European Parliament (1), Whereas: The Schengen information system (SIS) set up pursuant to the provisions of Title IV of the Convention of 19 June 1990 implementing the Schengen Agreement of 14 June 1985 between the governments of the States of the Benelux Economic Union, the Federal Republic of Ger- many and the French Republic on the gradual abolition of checks at their common borders (?) (the Schengen Con- vention), and its development, SIS 1+, constitute an essen- tial tool for the application of the provisions of the Schengen acquis as integrated into the framework of the European Union. (1) Opinion of 25 October 2006 (not yet published in the Official Jour- nal). (3 OJ L 239, 22.9.2000, p. 19. Convention as amended by Regulation (EC) No 1160/2005 of the European Parliament and of the Council (OJ L 191, 22.7.2005, p. 18). 2 The development of the second generation of SIS (SIS 1I) has been entrusted to the Commission pursuant to Coun- cil Regulation (EC) No 2424/2001 (3) and Council Deci- sion 2001/886[JHA of 6 December 2001 on the development of the second generation Schengen Informa- tion System (SIS 1) (4). SIS II will replace SIS as created pursuant to the Schengen Convention. This Decision constitutes the necessary legislative basis for governing SIS II in respect of matters falling within the scope of the Treaty on European Union (the EU Treaty). Regulation (EC) No 1987/2006 of the European Parlia- ment and of the Council of 20 December 2006 on the establishment, operation and use of the second genera- tion Schengen Information System (SIS II) (°) constitutes the necessary legislative basis for governing SIS II in respect of matters falling within the scope of the Treaty establishing the European Community (the EC Treaty). The fact that the legislative basis necessary for governing SIS II consists of separate instruments does not affect the principle that SIS I constitutes one single information sys- tem that should operate as such. Certain provisions of these instruments should therefore be identical. SIS 1 should constitute a compensatory measure contrib- uting to maintaining a high level of security within the area of freedom, security and justice of the European Union by supporting operational cooperation between police authorities and judicial authorities in criminal matters.
