The Netherlands are internationally at the forefront of applying article 1F of the Refugee Convention. It has resulted in the existence of a group of hundreds of mainly Afghan and Iraqi asylum claimants who are excluded from refugee protection due to their alleged involvement in international crimes, such as war crimes, crimes against humanity, and genocide. Although determining whether the exclusion clause applies is challenging in itself, this article demonstrates that developing a consistent post-exclusion policy appears to be even more complicated. A lack of harmonization in international law results in those excluded persons who cannot be prosecuted, or deported to their country of origin due to human rights concerns, being left in limbo. On the basis of interviews with twenty-four excluded asylum claimants in the Netherlands, this article presents a unique insight into the effects of this fundamental system error. It describes the economic, social, and health deprivation they face and discusses how the excluded persons themselves suggest solving the situation. The article also analyzes the (ad hoc) measures the Dutch government has taken in an attempt to resolve this issue and the informal strategies deployed by the excluded persons themselves. The authors conclude that only a profound adjustment of international law could bring a universal, coherent, and durable solution to the identified system error. Alternatively, it could be considered to reconcile various ad hoc solutions of existing post-exclusion measures. © The Author (2014). Published by Oxford University Press. All rights reserved.
