Convention arguments are regularly raised before the Belgian courts, yet many cases stop when the domestic proceedings end. A Convention argument rejected in Belgium is not necessarily a Convention case without prospects.
Belgian courts regularly deal with the European Convention on Human Rights.
Article 3 is invoked in detention and removal cases. Article 5 in deprivation-of-liberty cases. Article 6 in criminal, civil and administrative proceedings. Articles 8 and 10 arise in privacy and freedom-of-expression disputes. Article 1 of Protocol No. 1 may be relevant in property and asset litigation.
The Convention is therefore firmly present in Belgian litigation.
And yet there is a striking gap.
Many cases in which Convention rights have been argued before Belgian courts simply stop when the domestic proceedings end.
The question is whether they all should.
For domestic counsel, a judgment of the Court of Cassation will often represent the natural end of litigation.
The available national avenues have been exhausted.
The judgment is final.
The file can be closed.
From a Strasbourg perspective, however, the same judgment can have a completely different significance.
It may be the moment when a new legal assessment should begin.
The question is no longer:
Is another Belgian appeal available?
It becomes:
Does the file disclose an arguable violation of the European Convention on Human Rights which can now be brought before Strasbourg?
That question belongs to another body of law.
Belgian lawyers regularly invoke Convention provisions before domestic courts.
That is important because a complaint intended for Strasbourg must normally have been raised domestically, at least in substance.
But merely mentioning Article 3, 5, 6, 8 or another Convention provision does not automatically create a Strasbourg case.
After the final domestic proceedings, the entire file has to be reassessed.
Which Convention complaint survived?
Was it sufficiently preserved?
What did the domestic courts actually answer?
Does the complaint concern a genuine Convention issue or simply disagreement with Belgian law?
What Strasbourg test applies?
Does existing European case-law support the complaint?
And is the issue sufficiently serious and sufficiently substantiated to justify international proceedings?
Those are not necessarily the questions that dominated the national litigation.
One of the greatest risks after cassation is simply reproducing the arguments that failed nationally.
Strasbourg is not a second Court of Cassation.
Its task is not generally to determine whether Belgian law was interpreted correctly.
A national argument may therefore need to be reconstructed.
A complaint about reasoning may raise Article 6.
A detention dispute may engage Articles 3 or 5.
A search or seizure may require analysis under Article 8.
A serious interference with assets may raise Article 1 of Protocol No. 1.
The legal question changes.
The issue becomes whether the underlying facts fall within the autonomous standards developed under the Convention.
Convention litigation requires a different legal mindset.
We are not aware of any public statistic showing how many Belgian judgments containing Convention arguments are subsequently subjected to a specialised Strasbourg assessment.
It would therefore be wrong to suggest that every unsuccessful case invoking the Convention should continue internationally.
Many should not.
Some complaints will have no reasonable prospect of success.
Some will face admissibility problems.
In others, the Belgian courts will already have correctly applied Convention standards.
But the opposite assumption is equally questionable:
The fact that a Convention argument has failed domestically does not mean that the Convention issue has disappeared.
A case can fail before a national court and still raise a serious Strasbourg question.
Belgian proceedings continue to generate litigation before the European Court.
In 2025, the Court decided 255 applications concerning Belgium, 232 of which were declared inadmissible or struck out. On 1 July 2026, 105 applications concerning Belgium were pending before a judicial formation.
The European Court also continues to deliver judgments in Belgian cases concerning criminal proceedings and fair-trial rights, the reception of applicants for international protection, deprivation of liberty and other Convention questions.
There is therefore no reason to assume that Convention issues end merely because the Belgian litigation has reached its institutional endpoint.
There is also very little time to decide.
Once the relevant domestic proceedings have ended, the Convention generally allows only four months to lodge an application.
The Strasbourg potential of a case therefore cannot safely be considered months after a domestic file has been archived.
It should be assessed immediately.
Domestic counsel does not have to become Strasbourg counsel.
Nor does the international lawyer need to take over the domestic case.
The two roles are different.
Domestic counsel knows the client, the evidence, the national proceedings and the domestic law.
Strasbourg litigation requires another assessment: admissibility, exhaustion, preservation, autonomous Convention concepts, European case-law and strategic selection of the complaints capable of being brought before the Court.
The two stages are complementary.
But they are not the same.
This is the gap on which Just Rights Europe focuses.
We do not seek to reopen domestic proceedings or replace national counsel.
The objective is narrower:
Once proceedings before the highest domestic courts have ended, to determine whether the case still has a European human-rights dimension which should not end there.
A Convention argument rejected in Belgium is not necessarily a Convention case without prospects.
Sometimes the end of the Belgian proceedings is precisely the point at which the Strasbourg case begins.
These notes are general information on Convention law; they do not constitute legal advice and do not create a lawyer-client relationship.
After the final decision of the highest national court, a case may be submitted to us directly, by the client or by national counsel.
