The main theme and sub-themes for the 6th Congress of AACC were chosen for several reasons:
The Role of the Constitutional Courts and Equivalent Institutions in Strengthening Constitutional Justice for Sustainable Society

Firstly, the themes are current and relevant as they align with global trends emphasizing the United Nations' Sustainable Development Goals (SDGs). These goals were mutually endorsed by 193 member countries on September 25, 2015, and efforts have been underway since 2016 to achieve these 17 goals by 2030. Notably, SDG 16: Peace, Justice, and Strong Institutions, is relevant to the justice system, aiming to promote peaceful societies, ensure access to justice, and build effective, accountable institutions. Several targets within SDG 16 directly relate to constitutional courts and equivalent institutions, such as promoting the rule of law at the national and international levels, and ensure equal access to justice for all (Target 16.3), ensuring public access to information and protecting fundamental freedoms, in accordance with national legislation and international agreements (Target 16.10), and enforcing non-discriminatory laws and policies for sustainable development (Target 16.b).

The Evolvement of Constitutional Justice for Sustainable Justice in the Changing World

Secondly, the UN Sustainable Development Solutions Network's 2023 Sustainable Development Report ranked Thailand 43rd out of 193 countries, leading in the ASEAN region and ranking third in Asia, behind Japan (21st) and South Korea (31st). Among AACC members, Thailand is second only to South Korea. The report indicates continuous improvement in access to and affordability of justice in Thailand.

Constitutional Justice as the Foundation of Sustainable Social Development

Thirdly, no previous AACC, WCCJ, or other regional constitutional court congresses have addressed the linkage between constitutional justice and sustainable development. Therefore, the proposed theme and sub-themes for the 6th Congress of AACC not only reflect a contemporary and globally recognized agenda but also highlight Thailand's leadership in sustainable development within ASEAN and AACC. The congress will serve as a crucial platform for exchanging ideas and practices to achieve collective goals for genuine sustainable development.
