[1] The House of Representatives (Maltese: Kamra tad-Deputati) has 65 members, elected for a five-year term in 13 five-seat electoral divisions, called distretti elettorali, with constitutional amendments that allows for mechanisms to establish strict proportionality amongst seats and votes of political parliamentary groups.
Maltese voters elect 6 MEPs (5 until 2011) to the European Parliament, or one every 69,342 voters - the lowest population-per-seat ratio in the EU,[2] 10 times smaller than the EU average (680,000) and 20 times smaller than the largest European Parliament constituency.
[3][4]: 263 Malta is thus the extreme case in the curve of the degressive proportionality function that allocates European Parliament seats to EU Member States constituencies.
The Constitution of Malta mentions the institute of referendum only in Article 66, sub-articles 3 and 4 (and even then implicitly).
However, all resulted in a vote in favour of the proposal and, with the exception of the 1956 integration referendum, they were all honoured by the responsible government of the day.
