The Kingdom of Belgium is a federal parliamentary constitutional monarchy. Belgium was formed into an independent state in 1830, and is one of the modern nation-states configured out of long independent linguistic regions. Official languages are French, Dutch and German. In 1957, Belgium was one of the original signatories of the Treaty of Rome creating the European Communities, and in 1948 Belgium joined with Luxembourg and the Netherlands in creating the Benelux Economic Union .

The Belgian Constitution was promulgated on 7 February 1831 after the separation of Belgium from the Netherlands. Its principal provisions have remained largely unchanged since that date, although it has been amended on various occasions. The most important amendments occurred in 1989 when three autonomous regions, Flanders, Wallonia and Brussels, were created out of what had been a unitary nation-state. After the conquests by Napoleon in 1795, the French codes were imposed on the Belgian provinces, and remained in application in the new Kingdom of Belgium in 1830. The following versions of the Belgian constitution are available in IALS:

Delperee F and Renders D, Code constitutionnel: textes en vigueur au 1 janvier 2005. (5rd edn, Bruylant, 2005)
[French version]

Raworth P (ed), Constitutions of dependencies and territories. (Oceana Publications, 1975-)
[English version updated to 2008]

Electronic versions of the constitution are freely available in German, Dutch and French on the Belgian Senate website.  An English version is available on the House of Representatives website.  Consolidated and original texts of the constitution are also available in World Constitutions Illustrated on HeinOnline from our Law Databases page.

Codes and statutes

Consolidated legislation

Belgium's civil law system is based on five codes: the Code civil (Civil Code); Code de commerce (Commercial Code); Code pénal (Penal Code); Code d'instruction criminelle (Criminal Procedure Code) and Code judiciaire (Civil Procedure Code). The present civil and penal codes are still very close to the French originals whereas the commercial code has adapted to Belgian tradition and practice. Civil procedure law has changed substantially and the French model Code de procédure civile has been abandoned with the introduction of the Belgian Code judiciaire of 1967. Criminal procedure has also been greatly modified by the amendments of 1978. In addition to the five major codes, there are important laws on fiscal, social and administrative matters, as well as rural and military regulations.

There is no official compilation or official codifications as such. The accepted compilation is the commercially published Les Codes Larcier. This is a French-language compilation of Belgian legislation in force. The current edition is:

Les Codes Larcier. Edition 2016. Tomes I-4.  (Larcier 2016, with supplements for 2017)

This work is totally comprehensive for current research demands, and makes individual editions of laws unnecessary unless one desires annotations. This is available in the Institute's Library, and, as Supplements are published every six months, is fairly up-to-date. Les Codes Larcier is also available on the commercial database Strada lex, to which IALS does not subscribe.

The Juridat database is a key source of freely available online legislation. It includes a comprehensive searchable full-text consolidated set of legislation (as well as the Moniteur belge).

Chronological legislation

Moniteur belge / Belgisch Staatsblad (Bruxelles, Direction du Moniteur Belge, 1831-)

This is the Belgian official government gazette, which officially publishes laws, regulations and decrees, etc. It is published daily (except on Sundays, Mondays and legal holidays) with French and Dutch parallel texts. It has quarterly and annual alphabetical subject and chronological indexes.  It is available free on Juridat website, from 1997 onwards.  IALS has it on microfilm from 1944-1974, 1976-1983 and 1995-2001.

An alternative source is the commercial publication, Pasinomie: collection complète des lois, décrets, ordonnances, arrêtés et réglements généraux. Bruxelles, Bruylant, 1788-.  IALS Library has a complete holding of this series in the Library as from 1788 onwards to date, but it is currently about 8-10 years behind in publication.

There are other sources for session laws, but none are held in the Institute's Library:-

Bulletin legislatif belge (Bruxelles, Maison F. Larcier, 1931-)

Published weekly. Contains legislation of general interest promulgated during the preceding week.

Bulletin usuel des lois et arrêtés (Bruxelles, Bruylant, 1539-)

Published bi-monthly. Contains legislation since 1539 in chronological order. However only the more important texts are published in full.

Omnilegie (Bruges, La Charte, 1952-)

Published monthly. A complete collection of key laws and regulations. Of special interest because of parallel texts in French and Dutch allowing comparison of legal terminology in both languages.

Recueil des lois, décrets et arrêtés / Verzameling der wetten, decreten, besluiten (Bruxelles, La Direction, Moniteur Belge, 1831-)

French and Dutch parallel texts. A selective compilation of the more important legislation appearing in the Moniteur belge. Available in the British Library Official Publications Library.

There is no general index published to legislation in force, however, one can subscribe separately to the indexes of the Moniteur belge:

Table chronologiques et alphabetiques du Moniteur belge (Bruxelles, Larcier, 1831-)

This is published monthly and cumulates through the current year of publication, so subscribers also receive an annual cumulated index.

All treaties that Belgium has signed since 1987 are available on the Foreign Affairs Department's Treaties Database.

Law reports

There are no official series of law reports in Belgium and the legal profession relies on unofficial sources for court decisions. Pasicrisie belge (Bruxelles, Bruylant, 1791-) is a commercial series which publishes decisions of the Supreme Court and a selection of Appeal and lower tribunal cases. This French-language series is in the Institute Library from 1814 onwards.

Reports on administrative law are published in the collection Recueil des arrêts du Conseil d'Etat (Heule, Editions administratives U.G.A., 1948-). This series is also in the Institute Library from 1948-1982, and from 1989 onwards.

Court decisions are reported and annotated in commercially published legal periodicals as well, e.g.:

Journal des Tribunaux, 1881-

Rechtskundig Weekblad, 1931-

Revue Critique de Jurisprudence Belge, 1947-

Revue Pratique des Sociétés Civiles et Commerciales, 1889-

Tijdschrift voor Privaatrecht, 1964-

All of these titles are in the Library.

A key source of freely available case law on the web is Juridat which includes a case law database with cases from the Supreme Court (Cour de Cassation) from 1990 onwards.

The websites of several individual courts also contain some case law for that specific court. The website of the Constitutional Court (Cour Constitutionnelle de Belgique) formerly known as the Cour d'Arbitrage, contains full-text case law of the court in Dutch, French and German from 1985 onwards. The Supreme Administrative Court of Belgium (Conseil d'Etat) website contains the full-text of decisions of the court from 1994 onwards.

Digest of cases

An important annual digest-index to case law and doctrinal writing available at IALS is:

Recueil permanent des revues juridiques / Permanent overzicht van juridische tijdschriften, 2008- 2014 (which continues the Recueil annuel de jurisprudence belge (Bruxelles, Larcier, 1950-2007))

This is known for short as the RPRJ or POJT, formerly the RAJB. IALS holds it from 1949 - 2014, but lacks volumes for the years 1954, 1960, and 1963-1970 inclusive, but these years are mostly covered by our holding of Répertoire décennal, mentioned next. The RPRJ is available electronically on the Stradalex database (to which IALS does not subscribe).

Répertoire décennal de la jurisprudence belge (Bruxelles, Bruylant, 1880-1980)

This is an important collection of digests of decisions and doctrinal writings in all areas of the law arranged by subject, and including annotations originally published in Pasicrisie belge. The most recent decennial digest is that covering 1966-1975 in eight volumes, published from 1979-1984. The Institute Library has 1956-1965 (8v.) and 1966-1975 (8v.).This series is no longer published.

An encyclopaedic work on Belgian law is:

Les Novelles: Corpus Juris Belgici (Bruxelles Larcier, 1931-)

The IALS holdings of this survey of Belgian law are no longer current and the volumes are kept in the reserve collection. Les Novelles follows the order of the articles in the codes, developing the text as a systematic treatise on each branch of the law. It is published in approximately fifty volumes and maintains a high standard of precise and scholarly information. The Library has many volumes of this series published up to 1985.
