Schengen and the Administration of Exclusion: Legal Remedies Caught in between Entry Bans, Risk Assessment and Artificial Intelligence

To create an area in which persons can move freely, the Schengen states committed to control their external borders to prevent irregular immigration and the entry of third-country nationals (TCN s) who are considered to be ‘a public order and security risk’. The exclusion of ‘unwanted aliens’ can be based on the mutual enforcement of national decisions, such as entry bans reported in the Schengen Information System, or objections against the issuing of a Schengen visa, based on the consultation procedure in the Visa Code. This contribution focuses on the right of TCN s to have access to effective remedies, both with regard to existing and newer mechanisms of exclusion. It argues that when dealing with the use of large-scale databases and risk assessment as basis for excluding admission, existing rules and case-law by the CJEU should be taken into account to ensure access to effective judicial protection for TCN s.
