Purpose of the Study: This study examines the ratio decidendi of Indonesian corruption court judges through the lens of Maqashid Shariah, focusing on Decision No. 29/Pid.Sus-TPK/2021/PN.Jkt.Pst in which Juliari Peter Batubara was sentenced to only 12 years’ imprisonment despite receiving bribes of IDR 32.48 billion from social assistance fund procurement, circumstances legally qualifying for capital punishment under Article 2(2) of Law No. 31 of 1999. This study addresses two questions: first, how do judges construct their ratio decidendi in capital-eligible corruption cases; and second, to what extent does such reasoning align with Maqashid Shariah objectives. Methodology: This study used a qualitative approach with a type of literature review. This approach was chosen because this study aims to understand and analyse the relevance of the death penalty to the prevention of corruption in Indonesia from the perspective of Maqashid Syari'ah in depth and comprehensively, involving the interpretation of legal concepts and religious principles. Results: The analysis reveals that judges prioritized the unprecedented mitigating consideration that the defendant had "suffered sufficiently from public insults and humiliation," disregarding catastrophic harm to social assistance recipients. This ratio decidendi contradicts Maqashid Shariah principles, particularly hifz al-mal and hifz al-nafs, demonstrating that capital punishment authorization in Indonesia remains ineffective not due to legislative deficiency but due to judicial reasoning that prioritizes defendants' social suffering over the welfare of corruption victims. Applications of this study: This research contributes direct evidence-based recommendations for Indonesian policymakers, legislators, and judicial authorities regarding how capital punishment authorization under Article 2(2) of Law No. 31/1999 should be interpreted and applied in accordance with Islamic jurisprudential principles Novelty/ Originality of this study: The novelty of this research is that it examines actual judicial ratio decidendi from specific court decisions on the urgency of death penalty implementation for corruptors in Indonesia. It also provides an analysis of this theme based on Maqashid Shariah principles, an approach that has not been previously employed.
