# Commission Implementing Decision of 1 July 2011 amending the SIRENE Manual (notified under document C(2011) 4574) (Only the Bulgarian, Czech, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Italian, Latvian, Lithuanian, Maltese, Polish, Portuguese, Romanian, Slovak, Slovenian, Spanish and Swedish texts are authentic) (2011/406/EU), Division 2.1.3: Negotiating the entry of a new alert if this is incompatible with an existing alert

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

If a request for an alert conflicts with an alert issued by the same Member State, the national SIRENE bureau shall ensure that only one alert exists in the SIS. Each Member State may choose the procedure to be applied.
If the alert requested is incompatible with an alert already issued by one or several other Member States, their agreement is required.
The following procedure shall apply:
(a) if the alerts are compatible, the SIRENE bureaux do not need to consult each other; if the alerts are independent of each other, the Member State that wishes to enter a new alert shall decide whether to consult;
(b) if the alerts are not compatible, or if there is any doubt as to their compatibility, the SIRENE bureaux shall consult one another using an E form so that ultimately only one alert is entered;
(c) alerts for arrest shall be entered immediately without awaiting the result of any consultation with other Member States;
(d) if an alert that is incompatible with existing alerts is given priority as the outcome of consultation, the Member States that entered the other alerts shall withdraw them when the new alert is entered; any disputes shall be settled by negotiations between the SIRENE bureaux. If agreement cannot be reached on the basis of the list of priorities established, the oldest alert is left in the SIS;
(e) if an alert is deleted, Member States who were not able to enter an alert are informed by the C.SIS. The SIRENE bureau should then be notified automatically by a message from N.SIS that an alert put on hold can be entered. The SIRENE bureau shall apply the entire procedure for entering an alert in the appropriate alert category.
