Introducing proportionality to Thailand’s regulatory impact assessment framework

The 2012 Recommendation of the Council on Regulatory Policy and Governance emphasises that OECD countries should adopt ex ante impact assessment practices that are proportional to the significance of the regulation’s anticipated impacts. This paper presents a proposal for a proportionality test for the ex ante analysis and ex post review of regulations in Thailand. It provides the theoretical foundations and introduces a structure for how threshold and proportionality tests can be administered within the decision-making process of Thailand’s legislative system. The paper concludes with key recommendations for Thailand on how proportionality and threshold tests should be structured within the country’s RIA system.
