The question that I need answered is: 2/ Does Directive 2004/38 allow or preclude national authorities from taking an expulsiondecision on ground of public security against an EU citizen due to a marital relationship witha non-EU national who is deemed to constitute a threat, even if potential, to public security incircumstances such as those of the present case?

Case C-4/22 Vador and Cersei France Vador is a national of the (fictional) Republic of Tatooine. He holds a Master of Science degree in the field of information technology awarded by Tatooine's University of Technology. This University has been the subject to EU 'restrictive measures" because of its links with the Tatooinean government in particular in the military field.

Unlike Cersei, Vador had to apply for an entry visa prior to entering France. His visa application submitted at the French embassy located in Tatooine was however turned down on the ground that any period of study in France would enable him to acquire knowledge which could be subsequently misused in Tatooine.

Unhappy with these two decisions, Vador and Cersei subsequently brought an action before the relevant French court which, in turn, decided to stay the proceedings and ask the Court of Justice the following two questions
