This is not new, Rule by Decree has been re-instated for this term of office, but it was actually granted to him several years ago shortly after he took office the first time.
He ruled de facto by decree during the transition period, between the time he revoked the old Constitution and the writing of the new Constitution (written by himself and his cronies). Once the new Constitution was in place, the congress passed a law "granting" him Rule by Decree. It seemed unnecessary at the time, since the new Congress was packed with his people, and the new Supreme Court was also packed with his people, and they already were acting as his rubber stamp. But really it was the other way around. It is Congress and the Supreme Court (and his made-to-order Constitution) that are irrelevant.
He rules over their heads, and has from the beginning. If they dare to question him, he threatens them with arrest (even including Supreme Court justices).
Anyway, the new Rule by Decree law is really a re-enactment of something they gave him 5 years ago.
