# Commission Decision of 4 March 2008 adopting the SIRENE Manual and other implementing measures for the second generation Schengen Information System (SIS II) (2008/334/JHA), Division 2.2.1: Compatibility of alerts and order of priority

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

Only one alert per Member State may be entered into the SIS II for any one person or object.
Therefore, wherever possible and necessary, second and subsequent alerts on the same person or object shall be kept available at national level so that they can be introduced when the first alert expires or is deleted.
Several Member States may enter an alert on the same person or object if the alerts are compatible.
Alerts for arrest (Article 26 of the SIS II Decision) are compatible with alerts for refusal of entry (Article 24 of the SIS II Regulation), alerts on missing persons (Article 32 of the SIS II Decision) and alerts for a judicial procedure (Article 34 of the SIS II Decision). They are not compatible with alerts for checks (Article 36 of the SIS II Decision).
Alerts for refusal of entry are compatible with alerts for arrest. They are not compatible with alerts on missing persons, alerts for checks or alerts for a judicial procedure.
Alerts on missing persons are compatible with alerts for arrest and alerts for a judicial procedure. They are not compatible with alerts for refusal of entry and alerts for checks.
Alerts for a judicial procedure are compatible with alerts for arrest and alerts for missing persons. They are not compatible with alerts for checks or alerts for refusal of entry.
Alerts for checks are not compatible with alerts for arrest, alerts for refusal of entry, alerts on missing persons or alerts for a judicial procedure.
Within alerts for checks, alerts issued for ‘discreet checks’ are incompatible with those for ‘specific checks’.
Different categories of alerts on objects are not compatible with each other (see the table on compatibility below).
The order of priority for alerts on persons shall be as follows:
arrest with a view to surrender or extradition (Article 26 of the SIS II Decision),
refusing entry or stay in the Schengen territory (Article 24 of the SIS II Regulation),
placing under protection (Article 32 of the SIS II Decision),
specific checks (Article 36 of the SIS II Decision),
discreet checks (Article 36 of the SIS II Decision),
communicating whereabouts (Articles 32 and 34 of the Decision).
The order of priority for alerts on objects shall be as follows:
use as evidence (Article 38 of Decision),
seizure (Article 38 of Decision),
specific check (Article 36 of Decision),
discreet check (Article 36 of Decision).
Departures from this order of priority may be made after consultation between the Member States if essential national interests are at stake.
