Constitutional Congress

A constituent assembly (sometimes also known as a constitutional convention or constitutional assembly) is a body or assembly of representatives composed for the purpose of drafting or adopting a constitution. As the fundamental document constituting a state, a constitution cannot normally be modified or amended by the state's normal legislative procedures; instead a constituent assembly, the rules for which are normally laid down in the constitution, must be set up. A constituent assembly is usually set up for its specific purpose, which it carries out in a relatively short time, after which the assembly is dissolved. A constituent assembly is a form of representative democracy.

Unlike forms of constitution-making in which a constitution is unilaterally imposed by a sovereign lawmaker, the constituent assembly creates a constitution through "internally imposed" actions, in that members of the constituent assembly are themselves citizens, but not necessarily the rulers, of the country for which they are creating a constitution. As described by Columbia University Social Sciences Professor Jon Elster:

Constitutions arise in a number of different ways. At the non-democratic extreme of the spectrum, we may imagine a sovereign lawgiver laying down the constitution for all later generations. At the democratic extreme, we may imagine a constituent assembly elected by universal suffrage for the sole task of writing a new constitution. And there are all sorts of intermediate arrangements.

Right after the 1948 Costa Rican Civil War that overthrow Rafael Angel Calderón Government, the leaders of the victorious side call for an election of a Constituent Assembly in the same year. The Assembly successfully drafted and approved the current Costa Rican Constitution.

During the French Revolution (from July 1789 to September 1791) a National Constituent Assembly (Assemblée nationale constituante) was formed when representatives assembled at the only location available – a tennis court – and swore the Tennis Court Oath on June 20, 1789, promising that they would not adjourn until they had drafted a new constitution for France. Louis XVI recognized the validity of the National Constituent Assembly on June 27, 1789.
