The bicameral National Parliament (Pyidaungsu Hluttaw or Assembly of the Union) comprises the lower house, the People’s Assembly (Pyithu Hluttaw or House of Representatives) and the upper house, the House of Nationalities (Amyotha Hluttaw).
Each of the fourteen major administrative regions and states has its own local Hluttaw: Region Hluttaw (Region Assembly) or State Hluttaw (State Assembly).
Laws and regulations passed by the Pyidaungsu Hluttaw and signed by the President or deemed to have been signed are published in the Myanma Naingngan Pyantan (Myanmar Gazette). The Gazette also publishes executive orders and instructions. It is published weekly in Burmese only. It is available on the Ministry of Information's Printing and Publishing website.
