The country has a multi-party system, traditionally defined by the existence of three large political parties: the Christian Social People's Party (CSV), the Democratic Party (DP), and the Luxembourg Socialist Workers' Party (LSAP). Historically, the three parties have won a large majority of the votes between them, but their total percentage has fallen recently, such that two additional parties, The Greens and the Alternative Democratic Reform Party (ADR) have recorded over 8% of votes at each of last two legislative elections. The CSV and its predecessor (Party of the Right) has provided the Prime Minister for all but 12 years since 1918, and has always been the largest party in the legislature. In this respect, Luxembourg has certain features of a dominant-party system, although coalition governments are the norm and the previous two governments did not involve the CSV.
Compulsory voting
Luxembourg's electoral system operates on the basis of compulsory voting, with a few exceptions. Luxembourg citizens aged under 75 years who reside in Luxembourg are required to vote, unless they reside in a different municipality from the one in which they are called to vote.[1]
Luxembourg citizens aged over 75 years, as well as Luxembourg citizens of any age who do not reside in Luxembourg, are not required to vote. If they choose to register to vote, voting becomes mandatory for them. Non-Luxembourg citizens who are eligible to vote in municipal and/or European Parliament elections are not automatically required to vote; however, if they choose to register to vote, voting becomes mandatory for them. The failure of a person to vote when required to law to do so is punishable upon the first offence by a fine of between €100 and €250. A repeat offence within 5 years is punishable by a fine of between €500 and €1,000.[2]
One must be eighteen years of age on election day.
One must never have been convicted of a criminal offence.
One must otherwise be in full possession of one's political rights (e.g. not be certified as insane).
In addition to the criteria outlined above, to stand for election to the Chamber of Deputies, one must be resident in Luxembourg. Furthermore, one cannot be a candidate if one is a judge or a member of the Council of State.[5]
Deputies are elected from four constituencies ('circonscriptions'). They are arranged geographically, as combinations of the twelve traditional cantons. The four circonscriptions are Centre, Est, Nord, Sud.[5]
As the constituencies are based on geographic region and traditional borders, they have greatly differing populations. To reflect this, each constituency elects a different number of deputies; Sud, with 40% of the national population, elects twenty-three deputies, whilst Est, with only 12% of the population, elects seven. Voters can cast as many votes as their constituency elects deputies (so, in Est, one can vote for up to seven candidates), which can be spread across party lists or concentrated behind one single party.[5]
Since 1979, Luxembourg has elected members to the European Parliament,[5] which is the primary representative organ of the EU, and, with the Council of the European Union, forms its legislative branch. Due to its small size, the Grand Duchy elects just six members out of a total of 732, which is more than only Malta (which elects five MEPs); nonetheless, Luxembourg's representation is disproportionately large compared to its population, and Luxembourg elects more MEPs per capita than any other country (see: Apportionment in the European Parliament).
MEPs are elected to five-year terms. The exact date of elections is decided by Luxembourg, allowing it to schedule them on the same date as elections to the Chamber of Deputies (as is usually the case).[5]
Eligibility
To be eligible to vote in elections to the European Parliament, one must fulfil the following criteria:
One must be eighteen years of age on election day.
One must never have been convicted of a criminal offence.
One must otherwise be in full possession of one's political rights (e.g. not be certified as insane) in one's own country of citizenship (Luxembourg or another member state).
If not a Luxembourgish citizen, must have been resident in Luxembourg for at least five of the past six years when enrolling on the electoral register.[5]
In addition to the criteria outlined above, to stand for election to the European Parliament, one must be resident in Luxembourg. There are also extra requirements if one is a non-Luxembourgish citizen, in which case, one must be in full possession of one's political rights in both Luxembourg and one's country of citizenship (if not a Luxembourgish national), and have resided in Luxembourg for the past five years (and not just five of the past six).[5]
Electoral system
The seats are allocated according to the D'Hondt method.
Each commune (municipality) has an elected communal council. The number of councillors varies from 7 to 19 based on the number of inhabitants; the exception being the City of Luxembourg where its communal council consists of 27 members.
The councillors are directly elected every six years on the second Sunday of October. The last elections were held on 8 October 2017. The law of 15 December 2017 further defines that, in case the parliamentary and communal elections coincide, the latter are held in June of that year.
Referendums
The referendum was introduced into the Constitution of Luxembourg by the constitutional revision of 1919.[7] The Constitution mentions the referendum in Article 51:[7] "Voters will be asked to vote by way of referendum in the cases and under the conditions determined by law." The only details about execution of referendums are found in Article 114 which deals with constitutional amendments.[7] There are no other provisions regarding referendums in Luxembourg.
The Constitution amendment first has to be passed by two-thirds absolute super-majority of the Parliament, and then:
either passed again after at least three months under the same terms,
or passed on the referendum, if a referendum is requested in first two months of the three-month period by
The referendum on constitutional amendment (defined in Article 114) is binding. Referendums in general (defined in Article 51) are not explicitly stated to be binding.
The general framework of the organizational arrangements of referendums is established by "The Act of 4 February 2005 on the national referendum".[7]
There were four referendums in Luxembourg since 1919:
