18.2.2015 Official Journal of the European Union L 44/75 COMMISSION IMPLEMENTING DECISION (EU) 2015/219 of 29 January 2015 replacing the Annex to Implementing Decision 2013/115/EU on the Sirene Manual and other implementing measures for the second generation Schengen Information System (SIS II) (notified under document C(2015) 326) THE EUROPEAN COMMISSION, Having regard to the Treaty on the Functioning of the European Union, Having regard to Regulation (EC) No 1987/2006 of the European Parliament and of the Council of 20 December 2006 on the establishment, operation and use of the second generation Schengen Information System (SIS II) (), and in particular Article 8(4), Article 9(1), Article 20(3), point (a) of Article 22, Article 36(4) and Article 37(7) thereof, Having regard to Council Decision 2007/533/JHA of 12 June 2007 on the establishment, operation and use of the second generation Schengen Information System (SIS II) (3, and in particular Article 8(4), Article 9(1), Article 20(4), point (a) of Article 22, Article 51(4) and Article 52(7) thereof, Having consulted the European Data Protection Supervisor, Whereas: (1) The second generation Schengen Information System (SIS II) entered into operation on 9 April 2013. It contains sufficient information allowing the identification of a person or an object and the necessary action to be taken. In addition, for SIS II to function effectively, Member States exchange supplementary information related to the alerts. This exchange of supplementary information is carried out by the Sirene Bureaux. (2)  To facilitate the work of the Sirene Bureaux and of users of SIS II involved in Sirene operations in their daily work, a Sirene Manual was adopted in 2008 through a former first pillar legal instrument, Commission Decision 2008/333/EC (), as well as a former third pillar instrument, Commission Decision 2008/334[JHA (*). Those Decisions were replaced by Commission Implementing Decision 2013/115/EU () in order to better reflect the operational needs of users and staff involved in Sirene operations, to improve consistency of working procedures and to ensure that technical rules correspond to the state of the art. (3)  Following the first year of operation of SIS II it is appropriate to amend Implementing Decision 2013/115/EU in order to reflect new challenges and operational requirements as well as to provide clearer provisions in some areas related to the processing of SIS II data. This should enhance legal certainty and further reinforce fundamental rights. (4)  Pursuant to Article 29(1) and Article 30(1) of Regulation (EC) No 1987/2006 and Article 44(1) and Article 45(1) Decision 2007/533[JHA an alert entered in SIS II is to be kept only for the time required to achieve the purpose for which it was entered. Considering the diverging practices of Member States concerning the definition of the point in time when an alert fulfils its purpose it is appropriate to set out detailed criteria for each alert category to determine when it should be deleted from SIS IL (5)  The United Kingdom does not take part in Regulation (EC) No 1987/2006 as a consequence of which it cannot search and enter alerts on refusal of entry or stay regarding third country nationals. It remains, nevertheless, be bound by the rules on compatibility and priority of all alert categories since SIS II constitutes one single system. Therefore it is necessary to define the procedure of consultation in case there is an alleged incompatibility between an alert issued by the United Kingdom and an alert on refusal of entry or stay issued by another Member State.
