This act regulates the harmonization and synchronization of regional regulations carried out by the Government. Meanwhile, according to Article 24A paragraph (1) of the 1945 Constitution of the Republic of Indonesia, the authority to examine statutory regulations under the law against the law is in the hand of the Supreme Court through a judicial review mechanism. This is also confirmed by the Constitutional Court in its Decisions Number 137/PUU-XIII/2015 and Number 56/PUU-XIV/2016 regarding the norm cancellation of regional regulation review by the Government.
