Belgian case law online: a guide to the official sources

Belgian case law has no single point of access. Judicial decisions live on JUPORTAL, administrative litigation on the Council of State's website, asylum and residence cases at the Council for Alien Law Litigation, consolidated legislation in Justel, tax doctrine on Fisconetplus. Each database has its own search engine, its conventions and its blind spots. One case question can therefore require three tabs, three search syntaxes and three freshness checks.

This guide maps the official Belgian and European legal sources a law firm needs day to day. It starts from the collection work of Jef, the legal AI assistant born at the Brussels bar and developed by a practising lawyer for Belgian firms: the repositories described here are the ones Jef collects and indexes continuously to answer with cited sources, and the volumes quoted are those published on its sources page. For each database: what it actually contains, what it does not, and how to organise research that crosses case law, legislation and doctrine without losing a morning to it.

One honest caveat up front: none of these databases is exhaustive, and no tool makes them so. We come back to this below, because it is the most expensive trap in online legal research.

Before you search: four questions to settle

Efficient research starts before the first keyword. Four checks avoid most dead-end searches:

• Identify the legal order involved: judicial, administrative or European. The database to consult follows directly from it.
• Date the facts: the applicable version of a text is not always the version in force today. Justel displays consolidated Belgian legislation, so check which version covered the period of the facts.
• Establish the language of the proceedings: Belgian repositories are bilingual, but a decision often exists only in its original language. Searching in both French and Dutch doubles your coverage.
• Check whether the matter is regionalised: Walloon, Flemish, Brussels and community legislation also lives in Justel, under headings specific to each federated entity.

Belgian case law: three official databases, three perimeters

JUPORTAL is the reference database for case law of the judicial order: around 145,000 decisions published by Belgian courts since 1990, from the Court of Cassation down to trial courts. The engine replaced the old Jure system of Juridat. Its strength is Court of Cassation coverage; below that level, publication largely depends on the courts themselves.

The Council of State publishes its own administrative litigation rulings: around 220,000 decisions since 1994. Public procurement, town planning, civil service: the primary source is there, not on JUPORTAL.

The Council for Alien Law Litigation is a case apart: around 268,000 rulings on asylum and residence since 2007. That volume exceeds the whole of JUPORTAL, for a single court. A practitioner of immigration law who sticks to the general databases misses the core of the field.

Justel, Fisconetplus, VLABEL: Belgian legislation and tax doctrine

Justel is the FPS Justice database of consolidated Belgian legislation: around 118,000 texts, from 1802 to today. It covers federal law and the legislation of the federated entities (Walloon Region, Flemish authorities, Brussels-Capital Region, French Community, German-speaking Community, COCOF, COCOM). Consolidation is its reason for being: the text displayed integrates successive amendments, whereas the Belgian Official Gazette publishes each text separately, as it is adopted.

Fisconetplus gathers around 23,000 documents of federal tax doctrine and administrative decisions: circulars, administrative commentaries, advance rulings. VLABEL, its Flemish regional counterpart, has published around 1,600 documents of tax doctrine since 2007. For a tax lawyer, these two repositories often weigh more in an opinion than the case law does: the administration commits its positions to writing there.

The second circle: EU law and company data

EUR-Lex gives access to around 48,000 documents of EU legislation and consolidated texts since 1952. Curia publishes around 31,000 decisions of the Court of Justice and the General Court of the EU since 1954. The Commission's DG Competition adds around 67,000 documents of competition decisions, dating back to 1964 depending on the matter. These repositories are not reserved for EU law specialists: a question on consumer law, data protection or public procurement is rarely resolved without a detour through the European norm.

Two less expected sources complete the toolkit. The CBE (KBO), the official register kept by the FPS Economy, lists around 1.9 million companies and their business units. The Central Balance Sheet Office of the National Bank of Belgium receives around 590,000 filings of annual accounts per year, in structured format since April 2022. To check an opposing party's exact registered office, legal form or financial health before serving a summons, these two databases save a great deal of pointless correspondence.

Which database for which search: the summary table

The right reflex matches each type of question to its primary source. The table lists the official repositories with the indicative volumes published on Jef's sources page.

These repositories evolve constantly: courts and administrations add documents every working day. A search dated three months ago is no longer an up-to-date search.

The trap: confusing published case law with rendered case law

The symptom is a classic. A colleague cites a first-instance judgment handed down six months ago, the press covered it, and no Belgian case law database holds any trace of it. Search by date, by court, by keywords: nothing.

The diagnosis fits in one sentence: in Belgium, the publication of judicial decisions is not systematic. Copies of judgments remain scattered across the country's court registries, and online databases contain only a fraction of them. The law of 16 October 2022 created a Central Register for decisions of the judiciary, intended to become the authentic source of judgments and, in a second phase, to open free public access to pseudonymised versions. The timetable has slipped several times: the first phase entered into force on 30 September 2023, public access was announced for the end of 2023 and then postponed to April 2024, without effective implementation by that deadline, as documented by Justice-en-ligne.

The fix, in the meantime: never conclude from a decision's absence online that it does not exist. Two concrete reflexes. Request a copy from the registry of the court concerned, or directly from the colleague who cites the decision. Note in the file which database you consulted and when: thirty seconds that document your diligence if the question comes back later.

Why we never work with a single database

A lawyer who builds research on a single database takes an avoidable risk: the perimeters do not overlap. JUPORTAL misses most administrative litigation, the Council of State does not publish asylum cases, Justel says nothing about case law, and no Belgian database contains EU law. Picking one good database is not enough; you have to chain the right databases in the right order.

The workflow we recommend fits in one diagram:

flowchart TD
    Q["Question from the case file"] --> O{"Which legal order?"}
    O -->|"Judicial"| JU["JUPORTAL"]
    O -->|"Administrative"| CE["Council of State"]
    O -->|"Asylum and residence"| CCE["Council for Alien Law Litigation"]
    O -->|"European Union"| EU["EUR-Lex + Curia"]
    JU --> V["Check the applicable text in Justel"]
    CE --> V
    CCE --> V
    EU --> V
    V --> D["Cross-check with doctrine and your own documentation"]
    D --> R["Sourced answer, references noted in the file"]

Jef applies this cross-checking by default: a single question queries all of these official repositories, collected continuously (new JUPORTAL items are indexed several times a day), and every answer cites the passages used. The method stays the one in the diagram; the tool removes the tabs.

Organise the research instead of stacking tabs

The official sources of Belgian case law and legislation are free, rich and fragmented. The method that holds up: identify the legal order, query the primary source, check the consolidated text, document the search in the file. The rest is a matter of tooling.

Jef (https://www.jef.chat) turns a firm's document base into an AI assistant with sourced answers, built on these same official Belgian and European repositories, detailed with volumes on the sources page. Registration is free, with 50 messages included to test the coverage on your own files.
