This article presents an analytical study of several asylum cases on which Czech courts issued rulings between 2007 and 2022. It focuses on exposing the ways in which asylum authorities/courts conceptually treat legal otherness on the basis of incomplete information in the practical context of asylum proceedings. It demonstrates how the judgments of Czech asylum courts deal with the legal differences of countries of origin in evidentiary interpretations of documents, such as transcripts of asylum interviews or country-of-origin information (COI), by reconstructing the conceptual frameworks in which the alterity of the origin countries' state legal systems and customary law is embedded. It identifies particular evidentiary concepts that help to ensure the sustainability of the formal categories of 'state' and 'legal system' despite their apparent incompatibilities with various unconventional legal actors that do not easily fit into the standard ontology of formal asylum law. In particular, Czech court rulings tend to conceptually frame unconventional legal authorities (like elders, traditional councils) as cultural entities, non-state actors, or private persons, which paradoxically disqualifies them from the ontological possibility of posing (or preventing) a threat to refugees by operating an (in)effective legal system. The article examines the implications of this way of framing the legal authorities and systems of other countries, focusing specifically on Afghanistan, Jordan, and Yemen, and discusses the possibility of applying an alternative of legal-anthropological conceptualisation of unconventional legal authorities.
