Armenia’s parliament uses complex mathematical rules to ensure political stability and minority representation

In short: The National Assembly of Armenia is a unicameral legislature governed by intricate electoral mechanics. From mandatory thresholds for political blocs to constitutional requirements ensuring opposition presence, the system is designed to balance power. It even includes provisions for second-round elections to guarantee a stable majority while protecting minority voices.

The Armenian National Assembly, or parliament, traces its legislative roots to 1918, when it was established as the Khorhurd following the nation's declaration of independence. After the Soviet era and the adoption of the 1995 Constitution, the modern unicameral body was formed. Today, it typically consists of at least 101 seats, though this number can fluctuate up to 200 in rare circumstances.

The electoral system is defined by proportional representation using closed party lists. To enter parliament, parties must secure at least 4% of the vote, while alliances face higher thresholds of 8% or 10% depending on their size. Crucially, the law mandates that at least three political forces must be represented. If a dominant party wins more than two-thirds of the seats, the system triggers a redistribution of mandates to ensure that other political forces hold at least one-third of the total seats.

Stability is further reinforced by a potential second round of voting if no coalition can be formed within six days of the initial results. The two top-performing forces compete, and the winner is granted enough mandates to reach 54% of the total seats. This mechanism aims to prevent legislative deadlock. Additionally, the constitution requires that four mandates be reserved for national minorities, and gender balance is encouraged by rules preventing any top segment of a party list from having more than 70% of representatives of the same sex.

The system is not without debate. Because the constitution requires one-third of mandates to be held by non-ruling parties, some argue that if opposition members withdraw, the ruling party should be forced to call snap elections. This interpretation remains contested and may eventually require a ruling from the Constitutional Court to resolve.
