Humanitarian actors who work with displaced persons have, in the event of a mass influx of refugees, a crucial role and responsibility in documenting and collecting relevant evidence for a transitional justice process. Moreover, an effective international protection system is vital for providing refugees the opportunity for a safe and dignified return to their countries of origin. On the other hand, conflict situations that cause mass influx of refugees not only shatter law and institutions in the refugees’ countries of origin, they also put enormous pressure on, and sometimes cripple, the international protection systems in the countries of asylum, especially when international responsibility-sharing mechanisms are unable to respond to the crisis effectively.
