Transit-Oriented Development (TOD) and the Legality of Private Residential Use on Expropriated Land Originally Acquired for Mass Rapid Transit Business

An Analytical Approach for Interpreting the Statutory Purpose of Expropriation — A Case Study of the Ashton Asoke Project (Supreme Administrative Court Decision No. 188/2566, Grand Chamber)

Abstract

This research examines the legality of the expropriated land use as addressed in the Supreme Administrative Court Decision No. 188/2566 (the Ashton Asoke case). The primary aim is to develop an analytical approach for interpreting the statutory purpose of expropriation in cases involving private residential development on land originally acquired for mass rapid transit business and other related businesses, particularly when such land use includes commercial purposes. The study applies the concept of Transit-Oriented Development (TOD) and employs a descriptive research methodology, with Ashton Asoke serving as the central case study. The analysis finds that Thailand's current interpretation of “purpose of expropriation” for mass rapid transit business and other related businesses remains overly stringent. Such interpretation, as adopted in the aforementioned decision, fails to consider the broader public benefits in the contexts of urban development and disregards the principle of proportionality. It also treats commercial benefits in expropriated land use as disqualifying factors. Furthermore, this interpretation does not consider the TOD concept— even though some current laws and policy instruments already reflect TOD-related principles, despite the absence of official TOD legislation. In contrast to international standards, this strict interpretive stance poses theoretical and practical challenges, potentially undermining constitutionally protected private property rights. Applying this analytical approrach, developed to address the issues identified in Thailand’s current legal interpretation, to Ashton Asoke, it finds that the land use in question is constitutional. Be that as it may, the land-use agreement in this case should be improved to leverage the public interest on the expropriated land in line with TOD. Parts of the Ashton Asoke project's roads, for instance, could be legally designated as privately owned public spaces (POPS) to facilitate a walkable connection, particularly for mass transit passengers, connecting the transit station, the expropriated land, and Soi Sukhumvit 19/2. Alternatively, revenue generated from such agreement could be earmarked to support TOD-aligned mass transit policies, such as funding the government’s 20-baht-flat-fare-for-all-metro initiative. Beyond offering an alternative analytical lens to the Supreme Administrative Court’s and the Council of State’s (Opinion No. 935/2567) reasoning, this study provides a stepping stone for future reinterpretation in expropriation cases. It also contributes to the development of legal and policy frameworks regarding expropriation and urban development around mass rapid transit stations in Thailand, with a strong hope to promote a more balanced and sustainable approach to public and private interests, and particularly constitutionally protected private property rights.
