The Interim Constitution provides for a Constituent Assembly, which was charged with writing Nepal’s permanent constitution. Under the terms of the Interim Constitution, the new constitution was to be promulgated by April 28, 2010, but the Constituent Assembly postponed the promulgation by a year because of disagreements. On May 25, 2011, the Supreme Court of Nepal ruled that the 2010 extension of the Interim Constitution was not right. Since May 29, 2011 the Constituent Assembly repeatedly extended the Interim Constitution.

On May 28, 2012, the Constituent Assembly was dissolved after it failed to finish the constitution after the latest extension, ending four years of constitution drafting and leaving the country in a legal vacuum.^[3][4] New elections were held on November 19, 2013 to the Second Nepalese Constituent Assembly and political leaders pledged to draft a new constitution within a year.^{[5][needs update]}. The new assembly expressly committed that the new constitution would be promulgated on January 22, 2015. However, due to continued differences on key issues including system of governance, judicial system and federation issues like number, name and areas of the states to be carved, the constitution could not be finalized and promulgated in time.
