Local elections

General information

Municipal councillors are directly elected every six years. Each municipality has a Municipal Council from which the College of Mayor and Aldermen, the executive body of the commune, generates.

The local elections and the formation of the political bodies of the municipality are governed by the amended electoral law of 18 February 2003 and the amended communal law of 13 December 1988, coordinated versions of which can be consulted on the legilux.lu website in the collection « Legislative, European and local elections », in the Communal Code.

Municipal council

The number of members of the Municipal Council is determined in accordance with the number of inhabitants of the municipality.

The Municipal Councils are composed as follows:

  • 7 members in municipalities with a population of 999 or less;
  • 9 members in municipalities with 1.000 to 2.999 inhabitants;
  • 11 members in municipalities with 3.000 to 5.999 inhabitants;

The Municipal Council of the City of Luxembourg is composed of 27 members.

After the elections, all councilors have to take up their mandate by September 1st at the latest.

College of Mayor and Aldermen

The College of Mayor and Aldermen of each municipality is composed of one mayor and two aldermen.

However, the number of aldermen may be fixed, by Grand-Ducal decree, at:

  • 3 aldermen in municipalities with 10.000 to 19.999 inhabitants;
  • 4 aldermen in municipalities with 20.000 inhabitants or more;

The mayor and aldermen are appointed after being proposed by the majority of newly elected members of the Municipal Council. The Grand Duke appoints the mayors while the Minister for Home Affairs appoints the aldermen.

The mayors and aldermen take their oath of office before the Minister for Home Affairs. The mayor swears in the other members of the municipal council in their municipality.

It is possible that a local counsellor wishes to resign before the end of his or her mandate. In this case, their resignation is given in writing to the Minister for Home Affairs. The Minister for Home Affairs accepts the counsellor’s resignation. This approval is communicated to the concerned person by a simple letter and becomes effective three days after its signature.

The mayor of the concerned municipality informs the municipal council of the counsellor’s resignation at its next meeting.

The mayor or alderman who wishes to resign as a municipal counsellor must have previously obtained his resignation as mayor or alderman from the appointing authority. In the case of the mayors, the appointing authority is the Grand Duke, while the appointing authority for the aldermen is the Minister for Home Affairs.

Resigning mayors and aldermen exercise their functions until their successors have been sworn in.
