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.

 为了创建一个人员可以自由流动的区域，申根国家承诺控制其外部边界，以防止非法移民和被认为是“公共秩序和安全风险”的第三国国民 ( TCN ) 入境。“不受欢迎的外国人”的排除可以基于国家决定的相互执行，例如申根信息系统中报告的入境禁令，或基于签证法中的协商程序反对签发申根签证。这个贡献主要关注TCN的权利 s 获得有效的补救措施，包括现有的和更新的排斥机制。它认为，在处理使用大型数据库和风险评估作为排除准入的依据时，应考虑 CJEU 的现有规则和判例法，以确保TCN 获得有效的司法保护 。
