The Localization of International Legal Norms: Cultural Translation and Legal Adaptation

Abstract

This study aimed to explore how international legal norms are culturally translated, institutionally adapted, and practically interpreted by legal and policy actors in Tehran. This qualitative study used semi-structured interviews to examine the localization of international legal norms in domestic legal and institutional settings. Participants were selected through purposive sampling from legal, academic, policy, and civil society sectors in Tehran. Interviews continued until theoretical saturation was achieved, resulting in 22 participants. Data were collected through in-depth semi-structured interviews lasting 45–75 minutes. All interviews were transcribed verbatim and analyzed using thematic analysis with the support of NVivo software. To enhance trustworthiness, the study used member checking, peer debriefing, analytic memo writing, and constant comparison. The analysis identified four main categories: cultural translation of legal concepts, institutional filtering and selective adaptation, professional mediation by legal actors, and tensions between universal norms and local legitimacy. Participants emphasized that international legal norms rarely enter domestic contexts in their original form; rather, they are reframed through moral language, constitutional principles, religious-cultural values, administrative routines, and institutional priorities. Findings showed that localization may support legal legitimacy when international norms are translated into locally intelligible frameworks, but it may also dilute rights-based commitments when adaptation becomes excessive or politically selective. The localization of international legal norms is a dynamic and contested process shaped by culture, institutions, professional interpretation, and legal-political negotiation. Rather than treating international law as either universally imposed or locally rejected, the study demonstrates that legal adaptation occurs through translation, filtering, negotiation, and selective institutionalization. Effective localization requires interpretive sensitivity, professional capacity, transparent institutional procedures, and safeguards against the erosion of core normative standards.
