Pragmatic Monism: The Practice of the Indonesian Constitutional Court in Engaging with International Law

The relationship between international and domestic law in Indonesia is the subject of prolonged debate caused by the silence of the Indonesian Constitution on the choice between monism and dualism, which affects constitutional adjudication. This article discusses how the Constitutional Court engages with international law in its decisions and how the debate between monism and dualism is affected by it. It argues that the practice of the Court falls neither within the traditional scope of monism nor dualism but tends to be eclectic, which can be termed pragmatic monism. Here, the Court considers an international treaty part of domestic law upon ratification. However, its contents are only applicable if they are consistent with the Constitution, the highest law in the country. Nevertheless, such pragmatism is not without consequences where the consistency of the constitutional system as a whole is compromised for the instrumentality of its individual decisions on societal well-being.
