The Municipal Assemblies nominate candidates for delegates to the Provincial and National Assemblies. The various mass organizations – unions, students', farmers' and women's federations, etc. – play an active role in the nomination of candidates. In each municipality, they will conduct a candidate search and present their recommendations to the Municipal Assembly who may accept or reject any or all of them by a secret vote. Nominees will usually live, work or have some other relationship with the district in which her or she is nominated. By law, up to half of the nominees may already be delegates to the local Municipal Assembly. As a result of the 1998 elections, for example, 46% of delegates elected to the National Assembly were already delegates to their local Municipal Assemblies.
