Introduction

Part I of this series examined the absolute prohibition on expulsion under Article 3 ECHR and the operation of the non-refoulement principle. Article 3, however, addresses only one dimension of Convention protection against expulsion: the risk of ill-treatment in the receiving country. In many cases, expulsion engages a distinct and equally fundamental concern — the disruption of the private and family life that the individual has established within the expelling State. This is the domain of Article 8 ECHR.

Unlike Article 3, Article 8 is a qualified right, subject to permissible interferences on specified grounds. Its application to expulsion proceedings therefore involves an exercise of proportionality, in which the interests of the State in maintaining public order or protecting national security are weighed against the personal, familial, and social ties of the individual concerned. As the Court has progressively clarified, this balance cannot rest on abstract formulae or formal status distinctions; it must take account of the concrete reality of the applicant’s integration and relationships within the host State.

1. The Scope of Article 8 in the Expulsion Context

Article 8 ECHR guarantees every person the right to respect for their private and family life, home, and correspondence. Although this provision does not confer an absolute right, it imposes on Contracting States an obligation to conduct a proportionate balancing exercise where expulsion — or any other exercise of public authority — threatens to disrupt the individual’s family ties and private life.

The Court has repeatedly held, particularly in relation to foreigners who have resided for extended periods in a Contracting State, that expulsion decisions which fail to take adequate account of the individual’s familial and social ties may violate Article 8. In this assessment, the Court’s scrutiny focuses on a range of elements: the applicant’s personal history, family circumstances, the nationality of their children, and the degree of integration into the host society.

Article 8 is not confined to protecting family unity. The provision has been interpreted as safeguarding, more broadly, the right of the individual to develop their personality, maintain social relationships, and preserve their physical and moral integrity. The Court does not reduce the concept of “integrity” to the risk of bodily harm; rather, it extends Article 8 protection to State interferences that threaten the mental, emotional, and social existence of the individual.

Where a foreign national has resided long-term in a Contracting State and faces expulsion, the Court will consider the social environment they have built, their professional situation, family relationships, and the development of their personal identity. The disruption of these elements may amount to a serious interference with the physical and moral existence of the individual. Consequently, expulsion decisions must not rest solely on abstract assessments of public order or public security; they require a careful weighing of the material and non-material bonds that the individual has established within their personal life.

2. Boultif v Switzerland: The Foundational Criteria

In Boultif v Switzerland,¹ the Court developed specific criteria for assessing the impact of expulsion on an individual’s private and family life. The applicant, an Algerian national who had married a Swiss citizen and established family life in Switzerland, faced expulsion on the basis of prior criminal offences.

The Court held that an expulsion decision resting purely on public order grounds could not be taken without examining its effects on the physical and moral integrity of the individual — in particular, the interference with family life under Article 8. Taking into account the genuineness of the marriage, the applicant’s degree of integration, and the level of risk of reoffending, the Court concluded that the expulsion constituted a disproportionate interference and accordingly violated Article 8.

Boultif thus established the analytical framework for assessing expulsion under Article 8, emphasising that any interference must be examined against multi-dimensional personal factors rather than formal legal categories alone.

3. Üner v Netherlands: The Systematisation of the Test

In Üner v Netherlands,² the Grand Chamber systematised the proportionality assessment applicable to expulsion decisions, formulating the criteria that would become the standard reference point in subsequent cases.

The applicant, a Turkish national, had come to the Netherlands at a young age, living there with his family for many years, receiving his education, and building his social life. The Court held that where such individuals face expulsion, the assessment must consider not only family ties but also the impact on the individual’s personal identity, sense of belonging, and moral existence.

In the specific circumstances of Üner, the gravity of the applicant’s criminal convictions — including a manslaughter conviction — constituted a significant public order justification. After weighing the risk of moral and personal disruption arising from the severance of familial and social ties against the State’s interest in maintaining public order, the Court found no violation of Article 8 on the particular facts. Nevertheless, the methodological importance of Üner lies in its crystallisation of the analytical framework: even where Article 8 is not ultimately violated, the State must nonetheless have engaged with the full range of relevant considerations.

4. Slivenko v Latvia: Settled Presence and De Facto Belonging

The Court’s interpretation of Article 8 extends beyond the protection of family unity to encompass the social environment, cultural belonging, and personal identity that an individual has constructed through their settled life. A forceful illustration of this approach is Slivenko v Latvia.³

The applicants had resided in Latvia for many years during the Soviet period and had established enduring social ties in the country. Following Latvia’s independence, State policy concerning the withdrawal of the former Soviet army led to the applicants’ expulsion, on the basis of their connection to the Soviet military. Latvia defended the expulsion on national security grounds.

The Court, however, held that the applicants’ deep-rooted ties with Latvian territory — evaluated independently of their nationality status — could not be disregarded, and that the expulsion constituted a disproportionate interference with their private and family life in violation of Article 8.

The Court’s reasoning demonstrates that an individual’s de facto belonging to the country where they live with their family cannot be ignored merely on the basis of their foreign status, and that non-citizen statuses also merit protection in terms of moral and social integrity. The judgment further indicates that, in the context of expulsion, the considerations to be weighed extend beyond criminality or security risks to include the qualitative bonds arising from long-term residence and social integration.

5. Further Illustrations: Al-Nashif and Mokrani

The Court’s case-law has repeatedly confirmed that de facto ties may secure Article 8 protection notwithstanding the individual’s non-citizen status.

In Al-Nashif v Bulgaria,⁴ the expulsion of a Jordanian national who had lived in Bulgaria with his family for many years and integrated into social life was held to violate Article 8, notwithstanding the State’s reliance on national security considerations.

Similarly, in Mokrani v France,⁵ the Court assessed the integration and family situation of an applicant with a significant criminal record whose children had been born in France, and held that the expulsion produced a disproportionate effect on the applicant’s family and social life, in breach of Article 8.

The divergent outcomes in Üner, Mokrani, and Al-Nashif illustrate the Court’s contextual assessment:

Criterion	Üner v Netherlands	Mokrani v France	Al-Nashif v Bulgaria
Type and gravity of offence	Manslaughter (violent, public safety concern)	Drug offence	National-security allegations, ideological grounds
Post-sentence situation	Served sentence; 10-year entry ban	Served sentence; expulsion not suspended	Detention and expulsion initiated directly
Family ties	Limited – children present but weak bonds	Spouse and children French nationals	Spouse and children residing in Bulgaria
Proportionality outcome	No violation of Article 8	Violation of Article 8	Violation of Article 8
Focus of analysis	Article 8 and Article 1 of Protocol No. 7 (State’s margin of appreciation; public order)	Article 8 (individual rights prioritised)	Articles 8, 5 § 4, and 13
Convention violations found	—	Article 8	Articles 8, 5 § 4, 13

When read together, these cases demonstrate that the Court affords protection not on the basis of formal statuses alone — such as citizenship or residence permit — but on the basis of the individual’s degree of social rootedness, development of personal identity, and de facto relationships in terms of moral and social integrity. Through this approach, the Court has made clear that an individual’s settled ties with the host society may prevail over abstract invocations of public security.

Conclusion to Part II

The Court’s Article 8 case-law establishes that expulsion measures may threaten not only the physical existence of the individual but also their moral and social integrity, and that the Convention extends its protection accordingly. Rather than relying on distinctions based on citizenship status, the Court treats factors such as the individual’s de facto ties to the host society, level of integration, and the depth of family life as determinative criteria for assessing the proportionality of expulsion decisions.

The Boultif–Üner line has produced a sophisticated methodology for balancing State interests against individual rights, moving beyond categorical approaches towards a contextual, multi-factor analysis.

However, substantive protection under Article 8 can only be effective where procedural safeguards accompany it. An individual is entitled not only to know the grounds of their expulsion but also to defend themselves against the decision in a legally effective manner. In this context, the procedural guarantees under Articles 5 and 13 ECHR form a complementary component of the Convention’s integrated protection regime in expulsion cases. Part III of this series turns to these procedural dimensions — detention, the right to an effective remedy, and, where applicable, the implications of Article 6 for expulsion proceedings.
