Armenia adopted its post-Soviet constitution by public referendum on 5 July 1995 by 68% of the voters. A commission headed by Ter-Petrosyan had drawn up the draft constitution. It provides for a strong presidential system of government with a weak legislative system, granting the president power to appoint and remove the prime minister, judges, and prosecutors. It also gives him liberal grounds for dissolving the legislature, declaring martial law, and limiting human rights by declaring a state of emergency. The president serves a 5-year term. The prime minister is nominated by the president and is subject to legislative approval. The prime minister with presidential and legislative approval appoints the Cabinet of Ministers. As of 2003, the unicameral National Assembly had 131 members, who serve 4-year terms.
