Elections for the Plushunian Parliament and the Regional Council of Plushunia were held on 9 September 2019 in Plushunia. All 25 seats in the Plushunian Parliament and 12 out of 14 seats in the Regional Council of Plushunia were contested using a party-list proportional representation system. The election resulted in the partial victory of the Democracy and Truth Alliance, which failed however to form a coalition government. It was the only election in Plushunian history when a bicameral legislature was elected and when the country was split in electoral districts, with the following legislative election reverting to the old system due to difficulties with bicameralism.
As with the March 2019 election, a closed-party-list proportional representation system was used for the Parliament election, the country being divided however in electoral districts corresponding to the regions of Plushunia, each region being allocated a number of Parliament seats (Bucharest region - 15 seats, Ialomița region - 6 seats, Aurești region - 2 seats, Argeș region - 2 seats) which were then distributed proportionally through the Droop quota method. This election was however the only one in which seats in the other legislative body of Plushunia, the Regional Council (established through the August 2019 constitution, disestablished by the October 2019 amendments), whose 12 members were elected by the same procedure, except each region was allocated the same number of seats (3).
