Rights

A newly revised constitution in force since 2023, in a constitutional monarchy

Reviewed· 2026-08-02

Luxembourg is a constitutional monarchy whose thoroughly revised constitution entered into force on 1 July 2023, modernising the 1868 text across four successive revisions. Constitutional review is exercised by the Constitutional Court, which decides questions of the conformity of statutes with the constitution referred to it by other courts.

Key rules

The revised constitution has applied since 1 July 2023, replacing the structure of the 1868 constitution.
The Constitutional Court rules on the conformity of laws with the constitution when a question is referred by another court.
The Grand Duke is head of state; since 2008 he promulgates rather than sanctions legislation.

Governing law

Constitution of the Grand Duchy of Luxembourg (1868)Comprehensively revised, in force 1 July 2023

In practice

Constitutional questions reach the Constitutional Court by referral from the court hearing a case, not by direct individual complaint. The 2023 revision reorganised the text into distinct chapters on the state, rights, and institutions.

GDPR supervised by the CNPD, the regulator of a major data-hosting hub

Reviewed· 2026-08-02

Data protection follows the GDPR, with a national implementing law of 1 August 2018. The National Commission for Data Protection (CNPD) supervises compliance and matters especially because Luxembourg hosts significant EU data-processing and financial infrastructure.

Key rules

Processing requires a GDPR lawful basis and must respect transparency and data-minimisation duties.
High-risk breaches must be notified to the CNPD, in principle within 72 hours.
The CNPD investigates complaints, issues guidance and can impose GDPR fines.

Governing law

General Data Protection Regulation (Regulation (EU) 2016/679)
Law of 1 August 2018 on data protectionNational implementation of the GDPR

Penalties and consequences

GDPR fines up to EUR 20 million or 4% of worldwide annual turnover
Corrective orders and processing limitations from the CNPD

In practice

Because Luxembourg is a base for many EU financial and technology operations, the CNPD acts as lead supervisory authority in a number of cross-border cases. Public bodies are exempt from administrative fines under national law.

Rights

Constitutional rights reinforced by the ECHR and EU Charter

Reviewed· 2026-08-02

The revised constitution contains a modernised catalogue of fundamental rights, and Luxembourg is bound by the ECHR and, when implementing EU law, the EU Charter. As a small, highly international jurisdiction, it applies European human-rights standards closely.

Key rules

The constitution guarantees equality, personal liberty, privacy, expression and assembly.
The ECHR is directly applicable and its case law is followed by the domestic courts.
Equal-treatment legislation implements EU anti-discrimination directives in employment and services.

Governing law

Constitution, fundamental rights provisionsAs revised in force 1 July 2023
European Convention on Human RightsDirectly applicable

In practice

The Centre for Equal Treatment (CET) promotes equality and assists victims of discrimination outside the courts. Convention rights can be raised directly in ordinary proceedings.
