Within the framework of the Return Expert Group (REG), this ad hoc query aims to identify innovative collaborations related to multistakeholder governance. The focus is on partnerships between national authorities, local authorities, and civil society organizations to facilitate information sharing, guidance, and case resolution for migrants with return decisions or those remaining undocumented and off the radar of national authorities. 

The Swedish government has established a committee to review aspects of Swedish legislation concerning the return procedures for third-country nationals. The committee's goal is to propose new measures and revisions to existing laws to enhance the effectiveness of the return process. Consequently, they initiated an ad hoc query to gather information about the regulations related to the limited validity period of return decisions and the duration of entry bans.

At the beginning of 2023, a coordination meeting of the directors of the Belgian closed detention centers was held. At this meeting, they expressed their concern about the significant increase in the trafficking of drugs inside their centers.
