Strengthening Checks and Balances in Indonesia’s Presidential System: A Constitutional Law Perspective

Abstract

The principle of checks and balances constitutes a fundamental component of constitutional democracy because it prevents excessive concentration of governmental power and ensures that every state institution operates within constitutional limits. Following the constitutional amendments of 1999–2002, Indonesia transformed its constitutional structure from a system dominated by the People’s Consultative Assembly and a powerful executive into a more horizontal distribution of authority among the President, the House of Representatives, the Regional Representative Council, the Constitutional Court, the Supreme Court, and other constitutional institutions. Nevertheless, the practical implementation of checks and balances remains challenged by multiparty presidentialism, oversized governing coalitions, weak parliamentary opposition, asymmetrical bicameralism, political influence over strategic appointments, tensions between lawmakers and the Constitutional Court, and insufficient institutionalization of meaningful public participation. This article examines the constitutional construction of checks and balances in Indonesia’s presidential system and proposes mechanisms for strengthening institutional accountability. The study employs normative legal research using statutory, conceptual, case, and institutional approaches. The findings demonstrate that Indonesia’s principal problem is no longer merely the formal distribution of constitutional authority but the substantive effectiveness of institutional controls. Strengthening checks and balances therefore requires revitalizing parliamentary oversight, enhancing the Regional Representative Council’s legislative role, guaranteeing compliance with Constitutional Court decisions, improving transparent and merit-based appointment mechanisms, strengthening meaningful public participation, and reforming party and coalition practices.
