Will the UK keep access to the Schengen Information System (SIS)?
Non-Schengen third countries do not have access to SIS. SIS is a measure that contributes to security within the EU, in which there are no internal borders. It is intrinsically linked to the free movement of persons. The Court of Justice has consistently defended the coherence of the Schengen acquis.
We need to set up new effective ways of data sharing on wanted and missing persons and objects, while taking into account the UK’s future status.
This would be achieved through alternatives for simplified, efficient and effective exchanges of existing information and intelligence between the United Kingdom and Member States law enforcement authorities, in so far as is technically and legally possible, and considered necessary and in the Union’s interest.
