# Commission Decision of 4 March 2008 adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS II) (notified under document number C(2008) 774) (Only the Bulgarian, Czech, Dutch, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish and Swedish texts are authentic) (2008/333/EC), Division

Extent: E+W+S+N.I.

At the request of another Member State add a flag.
Articles 24 and 25 of the SIS II Decision allow a Member State to refuse to perform a requested action on its territory at any time by requesting that a flag be added to the alerts for arrest (Article 26 of the Decision), alerts for missing persons (Article 32 of the Decision) and alerts for discreet or specific checks (Article 36 of the Decision) when it considers that giving effect to the alert would be incompatible with its national law, its international obligations or essential national interests. The reasons for the request shall be provided simultaneously.
An alternative procedure exists only for alerts for arrest. Each Member State shall detect the alerts likely to require a flag as swiftly as possible.
If the circumstances mentioned in Article 24(1) or 25 of the SIS II Decision no longer exist, the Member State that requested the flag shall ask as soon as possible for the flag to be revoked.
