This report provides an overview of the rules and practices for the enforced return of third-county nationals in an irregular situation in Norway, France, Poland and Sweden. These countries belong to the Schengen area and apply a similar body of law. Yet, situations differ, in particular as regards the scope of the challenges, the nature of the actors involved, the type of decisions and the use of re-entry bans. The adoption of the EU “Return Directive” will result in a greater approximation of national legislation in the coming years. This context creates opportunities for Norway to review its rules and practices, and for European countries to engage in mutual learning and cooperation.
