Since the creation of ASEAN in 1967, the organisation has evolved and developed. One of the most important developments has been the initiation of the ASEAN Community and the mainstreaming of the idea of human rights in the region. The member states have agreed to accommodate the ideas of human rights and human protection into ASEAN frameworks and mechanisms. To this point, there are still debates among scholars on explaining the extent to which the ASEAN Human rights system have to constitute the regional identity and behaviour on human rights. The debate can be explained from two different application of the logic of action namely the logic of consequences and logic of appropriateness. At this point, this research applies an alternative logic of action so-called the logic of arguing to understand the dynamic behaviour of ASEAN countries in the evolving of its human rights system especially in relation to AICHR and AHA Centre. This research uses a qualitative case study. A case study approach has been chosen because it focuses on a detailed description and analysis of certain cases (Denzin and Lincoln, 2011) and it allows a researcher to examine theories and gain new insight from the evidence (Bryman, 1989). Generally, the data sources in this research are document-based including official statements and documents by ASEAN and its member states related to human rights and human protection issues. In addition, the relevant existing literature on this topic will be used. This research is expected to be published in a reputable international journal.
