This study aims to provide valuable insights and shed light on the overlooked aspect of Shariah governance (SG) in Türkiye by examining the role and position of the Participation Bank Association of Türkiye (PBAT) Advisory Board, a crucial actor in SG. In this concept, to collect data, the present study employed a semi-structured interview as a qualitative research method to examine the role and functions of the PBAT Advisory Board. This study included eight participants, who were members of the Advisory Board, specialists, and managers of the PBAT. Our findings offered significant insights into various themes, such as corporate governance, services, impact, fatwa, and the SG framework. This study also revealed several prominent themes, notably the SG framework and impact, which extensively discussed establishing SG in Türkiye. The theme of fatwa and services explored the activities undertaken by the organization, while the corporate governance theme shed light on its organizational characteristics. These findings contributed valuable and comprehensive insights, enhancing our understanding of the intricacies and nuances within these domains. SG mechanisms in Türkiye have recently shifted towards centralization. This study provides valuable insights using a comprehensive case study approach. The policy recommendations derived from this research can serve as a practical guide for policymakers, aiding in developing SG in Türkiye and providing a clear roadmap for future initiatives.
