    Questions about constitu­tional law in Ex Ante

    Which constitutional law sources does Ex Ante search?

    The judgments of the Constitutional Court, the case law of the Council of State and the Court of Cassation, the Constitution, the Special Act on the Constitutional Court, the Special Act on Institutional Reform, the parliamentary preparatory works and legal literature.

    Can I search only the judgments of the Constitutional Court?

    Yes. You filter by institution and refine by date and language. With Exclude party arguments switched on, Ex Ante searches only the Court's reasoning, not the summary of the parties' positions.

    Can I find both actions for annulment and preliminary questions?

    Yes. Ex Ante contains the Constitutional Court's judgments on actions for annulment and on preliminary questions, and the case law in which the question was referred.

    How do I find case law on an article of the Constitution?

    Type the article, for example "articles 10 and 11 Constitution". Ex Ante shows the text of the articles and the case law and legal literature that apply them, each opened at the passage where they are discussed.

    Can I search in plain language, without knowing the exact terms?

    Yes. Ex Ante searches by meaning. A question like "is it unequal treatment that two kinds of claims have a different limitation period" also finds judgments on the equality principle and reasonable justification.

    Can I also find legal literature on constitutional law?

    Yes. Ex Ante searches journal articles, handbooks and doctoral theses on constitutional law, alongside the case law and legislation. For a judgment, you also find the commentary published on it.

    Can I also find the preparatory works of a contested act?

    Yes. Ex Ante contains the parliamentary documents of the Chamber and the Flemish Parliament. You read the legislator's intention next to the judgment that assesses the provision.
