2.12.Exchange of information in case of interlinked alerts
Article 37 of the SIS II Regulation and Article 52 of the SIS II Decision provide Member States with the possibility to create links between different alerts, in accordance with their national legislation, with a view to revealing relationships among persons and objects entered into the SIS II. Such links shall only be created when there is a clear operational need.
2.12.1.Technical rules
Each link allows for the establishment of a relationship between at least two alerts.
A Member State may create a link between alerts that it enters in the SIS II and only this Member State may modify and delete the link. Links shall only be visible to users when at least two alerts in the link are visible to them. Member States shall ensure that only authorised access to links is possible.
2.12.2.Operational rules
Links between alerts do not require special procedures for the exchange of supplementary information. Nevertheless the following principles shall be observed:
In case there is a hit on two or more interlinked alerts, the SIRENE Bureau of the executing Member State shall send a G form for each of them.
No forms shall be sent on alerts which, although linked to an alert on which there was a hit, were not respectively the object of the hit. This rule shall not apply in the case when a linked alert for which there was no hit is an alert for arrest or for a missing person (protection). In this case the communication of the discovery of the linked alert shall be carried out using an M form.
