Case law of the Central Appeals Tribunal (Netherlands) on asset investigation in Türkiye

Centrale Raad van Beroep (Central Appeals Tribunal) · rulings of 1 October 2018 · ECLI:NL:CRVB:2018:2911 to 2914 inclusive

In brief

On 1 October 2018, the Centrale Raad van Beroep (Central Appeals Tribunal), the highest Dutch administrative court in social security cases, ruled in four cases that evidence of concealed real estate obtained in Türkiye (Turkey) may be used to withdraw and recover social assistance. Two of those cases concerned investigations by Bureaubuitenland. These rulings do not apply in Belgium, but show how a highest court has assessed the same method.

Dutch case law, for background

The Central Appeals Tribunal (CRvB) is a Dutch court. Its rulings do not bind the Belgian courts. We include them because the defences dealt with in them, privacy, discrimination, proportionality and unlawfully obtained evidence, are the same as those raised in Belgian cases. For Belgian case law: see case law.

Lawfulness of the investigation

After a large number of earlier rulings, on 1 October 2018 the CRvB ruled in four cases on appeals alleging unlawfully obtained evidence. Two of them (ECLI:NL:CRVB:2018:2911 and 2912) concerned investigations that Bureaubuitenland had carried out in Türkiye for a Dutch inter-municipal social services department. In both cases, a pre-check had preceded the asset investigation.

The ruling was clear: municipalities and the Sociale Verzekeringsbank (Social Insurance Bank) were permitted to use the evidence of concealed real estate obtained in Türkiye to withdraw and recover social assistance. In line with settled case law, the Tribunal added:

Evidence is only unlawful if the means of evidence have been obtained in a manner so contrary to what may be expected of a properly acting government that such use must be considered inadmissible under all circumstances.

And further:

No rule of Dutch law, including treaty law, prescribes that evidence gathered by, on behalf of or under the responsibility of Dutch administrative bodies must have been obtained lawfully under Turkish law.

Under Dutch law, however, there must be a fair trial (Article 6 ECHR) and protection of private life (Article 8 ECHR). The law of the commissioning party’s country is therefore decisive.

Privacy (Article 8 ECHR)

The CRvB consistently rejects the argument of a breach of private life. On the consultation of data in digital registers, the Tribunal considers that this constitutes a limited and acceptable interference with the right to respect for private life.

Prohibition of discrimination (Article 14 ECHR)

Here too the CRvB is clear: no unjustified distinction may be made between persons born abroad and persons born in the Netherlands. An investigation into assets abroad may therefore not be directed exclusively at benefit recipients with a place of birth abroad. This is why we only investigate on the basis of a concrete suspicion in a case file, never on the basis of origin.

Proportionality and subsidiarity

The Tribunal considered that it could not be held that a less intrusive means of investigation had been available at any time to examine the lawfulness of the social assistance, because the persons concerned had not themselves declared the ownership of the assets. The requirements of proportionality and subsidiarity had thus been met.

International law

Insofar as it was argued that the Dutch State acted contrary to international law by having investigations carried out without the permission of the Turkish authorities, this could not assist the persons concerned: those rules of international law protect the interests of the Turkish State, not those of the persons concerned.

The pre-check as a screening instrument

ECLI:NL:CRVB:2018:2912 states that the asset investigations were preceded by a number of screenings. On the group that remained after the third screening, Bureaubuitenland carried out a pre-check in Türkiye. On that basis, the investigation assignment was issued. In that case, the use of the pre-check as a screening instrument did not stand in the way of the use of the evidence. Each ruling relates to a specific case file and offers no guarantee for the outcome of another case. Nor does a pre-check in itself establish fraud. How the pre-check works today is explained under pre-check.
