The Chamber of Deputies (Luxembourgish: D'Chamber, French: Chambre des Députés, German: Abgeordnetenkammer), abbreviated to the Chamber, is the unicameral national legislature of Luxembourg. 'Krautmaart' is sometimes used as a metonym for the Chamber, after the square on which the Hôtel de la Chambre is located.

The Chamber is made up of 60 seats. Deputies are elected to serve five-year terms by proportional representation in four multi-seat constituencies. Voters may vote for as many candidates as the constituency elects deputies.


The constitution of 1841 created the Assembly of Estates (Assemblée des États), consisting of 34 members. Under the absolute monarchy of William II, King of the Netherlands and Grand Duke of Luxembourg, the legislature's powers were very restricted: it could not take decisions and had a purely advisory role with respect to the monarch. Its consent was necessary in very few matters. Only the sovereign could propose laws. The assembly was only in session 15 days a year, and these sessions were held in secret.[1]

In a climate marked by the democratic revolutionary movements in France and elsewhere, a new constitution was drafted in 1848. This introduced a constitutional monarchy: the King-Grand Duke only retained those powers specifically enumerated in the Constitution. The parliament, now called the Chambre des Députés, had the legislative power: it had the right to propose and amend laws. It would decide the budget, and received the power to investigate. The government became accountable to the Chamber. In addition, its sessions were now public.[2]

In 1853, William III called on the government to write a new constitution to limit the powers of the Chamber. The latter refused to approve the government's revisions, and the Grand Duke dissolved the legislature. There was then a brief return to absolutist monarchy. The parliament, now renamed the Assemblée des Etats, retained its legislative powers, but the Grand Duke was no longer required to approve and promulgate its laws within a certain period. Taxes no longer had to be voted on annually, and the permanent budget was re-introduced. The Council of State was created in 1856 as a check on the Chamber. Its role was to render opinions on proposed bills and regulations. [3]

After Luxembourg's neutrality and independence had been affirmed in the Second Treaty of London, in 1868, the constitution was revised to obtain a compromise between the liberties of 1848 and the authoritarian charter of 1856. The parliament was renamed the Chambre des Députés and regaind most of the rights it lost in 1856, such as the annual vote on the budget and taxes. However, the King Grand-Duke still kept wide-ranging powers: he exercised executive power, and wielded legislative power alongside the Chamber.

The constitutional changes of 1919 brought in universal suffrage and affirmed the principle of national sovereignty. These steps on a pathway of democratisation took place in a period of crisis of the monarchy, famine, and difficulties in supplying food. The Grand Duke remained the head of state, and the co-wielder of legislative power.

During World War II, from 1940 to 1944 the Chamber was dissolved, and the government and monarchy went into exile.

The first post-war session was opened on 6 December 1944 and was limited to one public sitting, as there was no quorum. A consultative assembly sat from March to August 1945, and new elections were held in October 1945. The post-war Chamber proceeded to revise the constitution again, which abolished the country's state of neutrality.

1965 saw the introduction of parliamentary commissions. The establishment of specialised and permanent commissions would facilitate the work of the legislature. The previous organisation of the Chamber into sections, un-specialised and with members chosen at random, had not been effective. Another innovation concerned political groups. They were now officially recognised, and received premises, and subsidies based on their proportion of seat. These material means were dwarfed by those established in 1990. [4]

Changes to the Chambers rules in 1990 and 1991 substantially increased the material means available to political groups, and contributed to a professionalisation of politics. In addition, every Deputy had the right to an office close to the Chamber building. The Chamber reimbursed the Deputies' staff expenses. Funds were now also available to "technical groups", following the protests of the small parties at the start of the new session in 1989.

In 2003, a new law established the office of the mediator and ombudsman. This was attached to the Chamber, put would not receive instructions from any authority in exercising his or her functions. They would deal with citizens' complaints concerning the central or local government administration, and other public entities. They would attempt to resolve disputes between parties, acting as a mediator. Every year, they would present a report to the Chamber.

Since January 2008, the political parties have been directly funded by the state. Their accounts were to be strictly separate from those of the parliamentary political groups. There were to be two different structures, each with their own staff. In order to receive public funds, a party must provide evidence of regular political activity, present complete lists of candidates at the legislative and European elections, and have received at least 2 % of the vote.[5]


The function of the Chamber of Deputies is covered under Chapter IV of the Luxembourgian constitution, the first article of which states that the purpose of the Chamber is to represent the country.[6] Luxembourg is a parliamentary democracy,[7] in which the Chamber is elected by universal suffrage under the d'Hondt method of Party-list proportional representation.[8]

All laws must be passed by the Chamber.[9] Each bill must be submitted to two votes in the Chamber, with an interval of at least three months between the votes, for it to become law.[10] Laws are passed by absolute majority, provided that a quorum of half of the deputies is present.[11]


The Chamber is composed of sixty members, called deputies. They each represent one of four constituencies, which are each a combination of cantons. Each constituency elects a number of deputies proportionate to its population, with the largest electing 23 and the smallest electing 7.

Electoral system

Deputies are elected by universal suffrage every five years, with the last election having been held on 7 June 2009. Deputies are elected by open list proportional representation, whereby all electors may vote for as many candidates as their constituency has seats. Each party is allocated a number of seats in proportion to the total number of votes cast for its candidates in that constituency. These seats are then allocated to that party's candidates in descending order of votes that each candidate received.

Hôtel de la Chambre

Main article: Hôtel de la Chambre

The Chamber of Deputies holds session in the Hôtel de la Chambre, located on Krautmaart, in the Ville Haute quarter of Luxembourg City. It was originally built between 1858 and 1860 as an annex to the Grand Ducal Palace, which had, until then, been used as one of many venues for the Chamber's convocations.[12]

The building was designed by Antoine Hartmann in a unified historicist style, combining elements of neo-Gothic, neo-Renaissance, and neo-classical architectural genres.[12] The Grand Ducal Palace, by contrast, was built over time in several architectural styles (primarily Renaissance and Baroque), but renovated in 1891 in a historicist neo-Renaissance manner.[13]
