Leading EU judgments

These judgments are important building blocks of European immigration law.

Court of Justice of the EU · 27 June 2018

Diallo — C-246/17

A decision on a residence card for a family member of an EU citizen must be made and notified within six months. Expiry of that period does not automatically result in a residence card.

Why does it matter?

The judgment emphasises timely decision-making and effective legal protection in EU residence procedures.

Court of Justice of the EU · 10 May 2017

Chavez-Vilchez — C-133/15

Where a third-country parent cares for a minor EU citizen, the child’s dependency on that parent must be assessed specifically. Merely referring to the other EU parent is insufficient.

Why does it matter?

The child’s best interests, daily care and emotional ties must genuinely be considered under Article 20 TFEU.

Court of Justice of the EU · 25 July 2008

Metock — C-127/08

The non-EU spouse of a mobile EU citizen need not have previously resided lawfully in another Member State to benefit from the Citizens’ Rights Directive.

Why does it matter?

The judgment protects the family life of mobile EU citizens and limits additional national entry conditions.

Court of Justice of the EU · 12 March 2014

O. & B. — C-456/12

An EU citizen who genuinely resided in another Member State and created or strengthened family life there may, under conditions, invoke a derived right of residence upon returning home.

Why does it matter?

This judgment guides return-route cases; short visits and holidays are not sufficient.

Court of Justice of the EU · 14 November 2017

Lounes — C-165/16

An EU citizen who acquires the nationality of the host state while retaining the original EU nationality may retain Treaty-based rights for a third-country family member.

Why does it matter?

Naturalisation need not extinguish previously exercised free-movement rights and related family life.

Practical files

Routes to residence

The correct route depends on nationality, the exercise of free movement, the country of application and the purpose of residence. A carefully prepared file helps prevent delay and unnecessary refusal.

Family reunification in the Netherlands

Residence with a Dutch partner or family member generally falls under the IND’s national rules. The relationship, income, civic integration and an entry visa may be relevant.

Key point
  • Conditions differ by family relationship and residence status.
  • Foreign documents often require legalisation and translation.
  • EU law applies to a Dutch sponsor only in specific situations, such as genuine residence in another Member State.

Family reunification in Belgium

The Immigration Office distinguishes between reunification with a Belgian, another EU citizen and a third-country national. Applications are generally filed abroad, although exceptions exist.

Key point
  • Income, housing and insurance conditions depend on the situation.
  • Long residence usually requires a D visa.
  • Clear and complete evidence of the family relationship is essential.

Family reunification with an EU citizen

Where an EU citizen lives in a Member State other than their country of nationality, EU free-movement rules may apply and a third-country family member may obtain a derived right of residence.

Key point
  • Nationality alone is not enough; the facts and exercise of free movement matter.
  • Family relationship, dependency and sufficient resources may be relevant.
  • On return to the home state, O. & B. and genuine family life are particularly important.

Other family member of an EU citizen — Article 47/1

In Belgium, another family member of an EU citizen may apply for residence under certain conditions. Article 47/1 includes family members who were dependent on the EU citizen or belonged to their household in the country of origin.

Key point
  • Dependency must already exist in the country of origin and be supported by evidence.
  • Regular financial support alone is not always sufficient; the full personal and financial situation is assessed.
  • Article 47/1 also covers a duly attested durable partner and relatives who require personal care from the EU citizen for serious health reasons.

Residence through work

Work in the Netherlands may require a combined residence and work permit, highly skilled migrant permit or another route. In Belgium, work exceeding 90 days commonly uses the single permit.

Key point
  • The future employer applies for the Belgian single permit.
  • A shortage occupation does not automatically guarantee admission.
  • In Flanders, the official medium-skilled occupations list differs from the broader VDAB shortage list; different conditions apply.

Current development

The EU Pact on Migration and Asylum

The new European rules are being introduced in stages. A large part of the Pact applies from June 2026. The precise consequences depend on EU rules, national implementation and the circumstances of each case.

We monitor implementation and assess which old or new rules apply to each matter.
