The debate about the federal system became taboo. This can be seen from the history of politics in Indonesia. There is an assumption that the federal system that was implemented using the RIS (Republic of Indonesia United States) Constitution in 1949-1950 is considered to have been formed by the Dutch colonial state, Van Mook. Therefore, during the New Order era with an authoritarian system, interpreting political history could only be carried out by the regime in power. The choice of government system in Indonesia, the 1945 Constitution also cannot be amended. All of them are considered "fixed price" as well as NKRI. This argument is basically caused by the interests of the elite regimes that want to dominate power. With a centralistic and monolithic system, power can be maintained. The second argument is that in the federal system, power is distributed between the federal (central) and the states. Centralistic and hierarchical military power will be threatened if the federal system is implemented. Hence the debate about the unitary or federal system of government did not develop. The decentralized system has in turn closed the federalism debate in Indonesia.
