Luxembourg courts explained: judicial and administrative order

The Luxembourg court system in the Vivre ensemble exam

The judiciary sits inside the institutions area, which accounts for 20 of the 40 exam questions. Within that area it is the biggest subtopic in the official material: there are more practice questions on the courts than on the Grand Duke, the Chamber of Deputies or the Government. Expect at least one or two court questions in any exam.

Constitutional Court, outside both orders

The good news is that the system has a clear logic. Once you know which kind of dispute goes to which order, and which court is first instance and which is appeal, most questions answer themselves. The hard part is a handful of confusable names, and this chapter flags each one.

For the other institutions, see Luxembourg's institutions (Grand Duke, Chamber, Government, Council of State) and Communes, elections and advisory bodies.

The judicial power: independent courts

The courts and tribunals form the judicial power, the third of the three classical powers. Their mission is to interpret the law and settle disputes. They apply the law adopted by the legislature; they do not make laws or direct public policy.

Independence

The defining principle of the judicial power is its independence. Judges receive no instructions from the Government, not by decree and not in a crisis. Parliament cannot exercise judicial power either, even by delegation. Courts are not part of the State administration: they are a separate power. This independence is what guarantees impartial decisions, a fair trial and the protection of fundamental rights, and it is what gives citizens trust in the justice system.

A court differs from a political body because its role is impartial adjudication. It does not answer to voters, and its members are not chosen for their party. Courts are permanent institutions, not set up for one occasion.

The National Council of Justice

The Constitution in force since 1 July 2023 created the National Council of Justice (Conseil national de la justice). Its task is to safeguard the independence of the justice system and its proper functioning. It is involved in the appointment of magistrates and in their ethics and discipline, which keeps those matters out of direct political control. The new Constitution and its other changes are covered on Luxembourg's 2023 Constitution.

Judicial vs administrative courts in Luxembourg: two separate orders

Luxembourg has two separate orders of courts, each with its own first instance and its own top court. Neither is above the other: the administrative courts are not superior to the judicial courts, and the judicial courts are not superior to the administrative ones. The difference between them is the nature of the dispute, not their rank.

Standing apart from both is the Constitutional Court (Cour constitutionnelle). It belongs to the judicial power in the broad sense, but it is part of neither order. Any court in either order can refer a constitutional question to it.

A simple way to picture the whole structure:

• Judicial order: justices of the peace → district courts → Superior Court of Justice
• Administrative order: Administrative Tribunal → Administrative Court
• Constitutional Court: to the side, answering questions referred by both orders

The judicial order: justices of the peace to the Superior Court of Justice

The judicial courts deal with civil disputes between private individuals and with criminal law. They apply the principle of equality before the law and are independent of the executive.

Justices of the peace

The three justices of the peace (justices de paix) sit in Luxembourg, Diekirch and Esch-sur-Alzette. They handle less significant matters: simple civil disputes and petty offences. A serious criminal case is never tried at first instance by a justice of the peace.

District courts

The two district courts (tribunaux d'arrondissement) sit in Luxembourg and Diekirch. They rule at first instance on the major civil and criminal cases. Appeals against their decisions go to the Superior Court of Justice.

The Superior Court of Justice

The Superior Court of Justice (Cour supérieure de justice) is the highest court in the judicial order. It rules on appeals and in cassation against decisions of the lower courts, and it keeps judicial case law consistent at the top of the order. Note the name: it is the Superior Court of Justice, not a "Supreme Court".

In cassation, a court does not re-examine the facts; it checks that the law was applied correctly. Appeals, by contrast, look at the case again. You do not need more detail than that for the exam.

The administrative order: Administrative Tribunal and Administrative Court

The administrative courts settle disputes between individuals and the public administration. If a ministry, a State agency or a commune takes a decision that affects you, for example refusing a permit, you can challenge it before the Administrative Tribunal. This includes acts of the Government acting as an administrative authority, and tax disputes.

Two levels, and a naming trap

The Administrative Tribunal (Tribunal administratif) rules at first instance. The Administrative Court (Cour administrative) rules on appeal and ensures the consistency of administrative case law at the highest level. The administrative courts were created by the constitutional revision of 1996 and took over the litigation role the Council of State had held until then.

Legality, not expediency

The administrative courts review the legality of administrative action, not its expediency. They check whether the administration was entitled to act as it did, not whether it made the best choice. They can annul an unlawful administrative act and, within the limits set by law, issue injunctions. Their decisions bind the administration, and they are independent of the executive. The principle behind all this is the rule of law: the administration must obey the law like everyone else.

The Constitutional Court of Luxembourg

The Constitutional Court (Cour constitutionnelle) reviews whether laws conform to the Constitution. It protects the supremacy of the Constitution over ordinary laws, which is why it is essential in a state governed by the rule of law. It is not a court of appeal, and it is not part of the ordinary judicial courts.

How a case reaches it

A citizen cannot go to the Constitutional Court directly: there is no direct appeal and no petition. A question reaches it only by referral (question préjudicielle) from an ordinary court. When a judge in any court, judicial, administrative, labour or social security, has a doubt about whether a law applied in a case conforms to the Constitution, the judge can refer the question. The Court then answers that question, and the referring court decides the case.

What it reviews, and what it does not

• It reviews laws, including laws already in force. It does not review municipal regulations, individual administrative acts or court decisions.
• It rules only on constitutional conformity, not on the facts of the case.
• It does not judge the political expediency of a law. That is judicial review, not intervention in political debate.
• It can be asked in any area of law, whenever a question of constitutionality arises.

The effect of its decisions

Its decisions are binding on the courts. The Court does not strike laws out of the statute book itself: it declares a provision not in conformity with the Constitution, and that provision then ceases to have legal effect from the day after the judgment is published, unless the Court sets a different date. This is the key contrast with the Council of State: the Constitutional Court issues binding judicial decisions on laws already voted, while the Council of State gives non-binding opinions on bills before the vote.

Labour and social security courts

Labour and social security courts belong to the judicial order. They are specialised because the disputes they handle concern work and social protection, areas where one party is often weaker than the other.

Labour courts

The Labour Tribunal (Tribunal du travail) handles individual disputes between employers and employees: employment contracts, dismissals and wages. Collective labour disputes can also be brought before a court, and labour courts can examine collective agreements. They apply the Labour Code, guided by the protection of the employee as the weaker party and by equality before the law. The social partners are involved through collective agreements and representation, but they do not deliver judgments.

Social security courts

Social security covers pensions, health insurance and social benefits. An insured person can challenge a decision of a social security fund. At first instance the case goes to the Social Security Arbitration Council (Conseil arbitral de la sécurité sociale), and on appeal to the Superior Council of Social Security (Conseil supérieur de la sécurité sociale). These courts are independent of the administration and can annul a decision of a social security body.

Labour courts, like all courts, can refer a constitutional question to the Constitutional Court.

Quick check: which court?

Run through these situations. If you can name the court for each, you are ready for most judiciary questions.

How to revise the courts chapter

• Draw the two ladders. On paper, draw the judicial order on the left (justices of the peace, district courts, Superior Court of Justice) and the administrative order on the right (Tribunal, Court). Put the Constitutional Court between them with arrows from both sides. Redraw it from memory until it takes under a minute.
• Learn the places with the numbers. Justices of the peace: Luxembourg, Diekirch, Esch-sur-Alzette. District courts: Luxembourg, Diekirch.
• Fix the word pairs. Tribunal before Court in the administrative order; legality, not expediency; referral, not direct appeal; opinion (Council of State) versus decision (Constitutional Court).
• Use the French names. The questionnaire may show Tribunal administratif, Cour administrative, Cour supérieure de justice and justice de paix.
• Focus on the traps. Several of the most-missed questions in CivicLearn practice data are about the court orders. They are collected on the most-missed questions page.

The official reference is the chapter on justice in "About Political Institutions in Luxembourg", listed on our study materials page. For timed practice, the practice questions page has a sample set, and the CivicLearn course includes a printable revision sheet on the courts and a common-traps mode that keeps returning to the questions you miss.
