Pengujian Satu Atap Sebagai Optimalisasi Penataan Regulasi dalam Sistem Ketatanegaraan Indonesia

Disharmonization of Indonesia's regulatory system has become a complicated issue. Many factors cause it. One of the factors causing disharmony of statutory regulations is the absence of centralized review of statutory regulations in a separate institution. Based on Articles 24A and 24C of the 1945 Constitution of the Republic of Indonesia, the review of statutory regulations in the Indonesian constitutional system is carried out by two separate institutions, namely the Supreme Court and the Constitutional Court. The decisions of the two judiciary institutions are final and binding and cannot be appealed, so the decisions must be implemented. Problems occur in the Indonesian constitutional system when the two institutions issue conflicting decisions, resulting in legal uncertainty regarding which norms should be applied. Therefore, one rooftop testing is something that is urgent to be implemented in the Indonesian constitutional system, as an effort to create regulatory harmonization. The research method used in this research is normative juridical. The research hypothesis is that a one-stop examination is necessary and should be given to the Constitutional Court.
