Council Decision 2007/533/JHA of 12 June 2007 on the establishment, operation and use of the second generation Schengen Information System (SIS II)

In 2013, the second generation Schengen Information System (SIS II) replaced SIS 1+. SIS II is a large-scale information system in the area of freedom, security and justice. It contains alerts on certain categories of persons and objects and it is considered crucial to maintaining a high level of security within the area without internal border controls (the Schengen area).

SIS II was established by Regulation (EC) No 1987/2006 and by Decision 2007/533/JHA. The later is the legal basis for the SIS II as far as co-operation in criminal matters (3rd Pillar) is concerned. Regulation 1987/2006 of 20 December 2006 has the same purpose for the part related to community law (1st Pillar). The Decision and the Regulation have the same content regarding for example organisational issues but they differ on the types of alerts.
