This article examines Constitutional Court Decision No. 40/PUU-XXIV/2026, which requires the separation of the budget for the Free Nutritious Meals (Makan Bergizi Gratis/MBG) Program from the education budget allocation through the perspective of siyasah dusturiyah, an Islamic legal-political framework governing the state and government. The decision, delivered on July 30, 2026, partially granted the petition submitted by the Taman Belajar Nusantara Foundation and five individual Indonesian citizens concerning the judicial review of the Elucidation of Article 22 paragraph (3) of Law No. 17 of 2025 on the State Budget for Fiscal Year 2026. The Court held that including the MBG Program within the education budget, which is constitutionally allocated at a minimum of 20 percent, with a total allocation of IDR 769.1 trillion, including IDR 223.6 trillion for the MBG Program, constituted a conditional constitutional violation of Article 31 paragraph (4) of the 1945 Constitution. This study employs a qualitative method with a case study approach and analyzes the legal considerations of the Constitutional Court. From the perspective of siyasah dusturiyah, the principles of ‘adl (justice), maslahah (public welfare), and wajib al-dawlah (the state's obligation) affirm that education is a constitutional right that must be prioritized. The Constitutional Court's decision reinforces constitutional boundaries in state budget management and emphasizes the importance of justice, transparency, and accountability in managing public finances for the benefit of present and future generations.
