How ‘Part Suitability’ Impacts Human Rights Applications

Key points

• Part 9 (General Grounds for Refusal) of the UK Immigration Rules has been deleted and replaced with a new Part Suitability.
• Article 8 of the ECHR protects private and family life, but it is a qualified right, so immigration decision-makers must balance individual circumstances against the public interest in immigration control and public protection.
• Home Office guidance on family life as a partner or parent and exceptional circumstances explains when decisionmakers must grant leave, even if suitability grounds apply, to avoid a breach of Article 8.​
• Recent reforms have consolidated refusal grounds into a comprehensive Part Suitability framework and sit alongside wider proposals for “earned settlement” and longer residence periods, which will shape longterm human rights strategies.
• Applicants should provide clear evidence of their family and private lives, and any exceptional circumstances, and should address directly any potential suitability issues, such as criminal history, deception, or overstaying.

Human rights applications under Article 8 of the European Convention on Human Rights (ECHR) are an essential route for people seeking to enter or remain in the UK on the grounds of their private or family life. These applications often arise when a person cannot meet the normal requirements of the Immigration Rules, or when past problems, such as overstaying or criminal convictions, create a risk of refusal.

From 2025 into 2026, the Home Office has been reshaping the general grounds for refusal into a single, comprehensive “Part Suitability” framework. This framework replaces Part 9 of the Immigration Rules. Still, the same ideas remain important: decision-makers consider a person’s character, conduct and immigration history before deciding any application, including those based on human rights.

At the same time, the Government has consulted on a move towards an “earned settlement” model with longer residence periods, which will directly affect many people who rely on Article 8 in longterm strategies.

Article 8 ECHR and its role in immigration cases

Article 8 protects the right to respect for private and family life, home and correspondence, but it allows the state to interfere with that right where the interference is lawful, pursues a legitimate aim, and is necessary in a democratic society. In immigration cases, this usually means that removal or refusal is permitted if it is justified by the need to control immigration, protect public safety, prevent crime or protect the rights of others.

The Home Office family life guidance sets out how Article 8 is reflected in the Immigration Rules, especially in Appendix FM (family life as a partner or parent) and the private life provisions. It stresses that the Immigration Rules are intended to strike a fair balance between the rights of individuals and the wider public interest. Decisionmakers must consider the best interests of any child affected by a decision and must look at all relevant circumstances, including length of residence, strength of relationships, and obstacles to family life continuing outside the UK.

Even when a person cannot meet the provisions contained in the Immigration Rules, or when there are suitability problems such as criminality or past deception, the Home Office must still ask whether refusing the application would breach Article 8. If refusal would be disproportionate in the individual case, the guidance says that leave should be granted despite those problems.

Part 9 and Part Suitability

Historically, Part 9 of the Immigration Rules set out the “general grounds for refusal”, dealing with issues such as criminal convictions, previous breaches of immigration law, deception, unpaid NHS charges, and national security concerns. These provisions applied across most visa categories, including human rights claims made in the UK.

On 14 October 2025, the Home Office published a wide-ranging Statement of Changes which, among other changes, deletes Part 9 (Grounds for Refusal) and inserts a new Part Suitability into the Immigration Rules.

Key features of the suitability framework include:

• Mandatory refusal where a person’s presence is considered “not conducive to the public good”, or where serious criminality or national security concerns arise
• Criminality thresholds that link different sentences to varying levels of concern, with some leading to automatic refusal and others allowing a casebycase assessment
• Refusal or cancellation based on serious or repeated breaches of immigration law, such as overstaying, illegal working or failure to comply with conditions
• Refusal for deception or nondisclosure, including where false documents or information have been used in an application
• Refusal related to unpaid NHS charges or civil penalties for illegal working or employing illegal workers

How Part Suitability and Article 8 fit together

The Home Office family life guidance makes it clear that suitability provisions are important, but they are not the end of the story in human rights applications. It states that where a person’s immigration application is refused under Part Suitability, the decisionmaker must still consider whether the refusal would breach Article 8. If it were, appropriate leave should be granted.​

In practical terms, this means that:

• Some suitability grounds such as criminality, national security threats, or persistent offending are treated as mandatory and these cannot succeed under the standard “exceptional circumstances” provisions of Appendix FM or Private Life.
• Decisionmakers must consider proportionality: the more serious the public interest concern (for example, serious criminality), the stronger the private or family life factors must be to outweigh it.
• Family life cases involving children require specific attention to the child’s best interests under section 55 of the Borders, Citizenship and Immigration Act 2009. However, in cases of serious criminality, national security threats, or persistent offending, the public interest factor is likely to override any interests of relevant children.

For example, a person with a short criminal sentence may fall within a discretionary criminality ground for refusal. The decision-maker then considers their family life, including any British children, their length of residence, and any rehabilitation, to decide whether refusing the application would be disproportionate under Article 8. However, in cases of of serious criminality, national security threats, or persistent offending, the bar for a successful human rights claim is now incredibly high.

Family life as a partner or parent and exceptional circumstances

The “Family life as a partner or parent and exceptional circumstances” guidance provides a detailed roadmap for Article 8 family life decisions. It explains when a person can meet the Rules directly and when leave should be granted outside the Rules based on exceptional circumstances.​

Important points in the guidance include:

• The need to assess whether family life exists between partners or between parent and child, looking at genuineness and the subsistence of relationships
• The best interests of any child as a primary consideration, including the impact of separation and disruption to education and support networks
• The public interest factors, such as immigration status, financial independence, criminality and compliance with immigration law
• The “insurmountable obstacles” and “very significant obstacles” tests for family life continuing overseas or for private life in the country of origin

The guidance also explains what is meant by “exceptional circumstances”. These are circumstances in which refusal would result in unjustifiably harsh consequences for the applicant or their family members, rendering it disproportionate under Article 8. This may include serious medical issues, children who have lived most of their lives in the UK, or families who cannot reasonably be expected to continue their lives in another country.

Private life, long residence and future proposals

Private life applications often rely on long residence, integration in the UK, and obstacles to life in the country of origin. Current guidance and commentary emphasise rules for children who have lived in the UK for many years, young adults who arrived as children, and adults with very long residence.

At the same time, major proposals for an “earned settlement” system have been published. These proposals would abolish the traditional 10year long residence route and replace it with longer residence periods, such as 10 years for most migrants, 15 years for those in roles below degree level, and 20 years for refugees. The Government’s consultation on these changes is expected to close in early 2026, with implementation likely later in the year.

If implemented as proposed, these reforms will have a real effect on human rights strategies based on longterm stay and private life. Individuals who previously relied on the 10-year route may find they need to build a stronger case under the private life rules or rely more heavily on exceptional circumstances, particularly where suitability issues are at play.

Current policy trends and human rights applications

In analysing the current policy trends, my opinion is they show:

• Stronger and more uniform suitability rules across all categories
• Closer scrutiny of criminality, deception, and overstaying
• A shift towards longer qualifying periods for settlement and a more structured “earned settlement” model
• Continued recognition of Article 8 rights, but with an expectation that applicants present clear, welldocumented cases

The comprehensive Part Suitability framework, highlighted in early 2026 commentary, consolidates these trends. It creates a more predictable structure for refusal decisions but may leave less informal discretion in borderline cases, increasing the importance of formal Article 8 analysis and the quality of evidence provided.

Practical implications for people making human rights applications

For people planning a human rights application based on Article 8, several practical points follow from the current law and guidance:

• Understand your starting point: Be clear whether your case is mainly about family life, private life, or both, and which Rules or policies are most relevant.
• Identify suitability risks early: Consider any criminal history, previous overstaying, deception, unpaid NHS charges, or other issues that may trigger Part Suitability.
• Prepare strong evidence: Collect documents that show the reality of your relationships, your residence history, your role in any children’s lives, your medical or care needs, and your integration in the UK.
• Explain exceptional circumstances: Use clear, simple language to describe why refusal would be harsh for you and your family, referring to the best interests of children and obstacles to life elsewhere.
• Stay informed about changes: Keep track of updates on Part Suitability, family life guidance and settlement proposals, especially if your case depends on long residence or complex histories.

For many people, it will be sensible to seek professional advice, particularly where suitability issues are serious or where previous applications have been refused. The interaction between Part Suitability and Article 8 can be technical, and small details in evidence and timing can make a significant difference.

FAQs

What is Part 9 or Part Suitability in the Immigration Rules?

Part Suitability (which has replaced and modernised the role of Part 9) is the part of the Immigration Rules that sets out when an application must or may be refused or cancelled because of issues such as criminality, deception, overstaying, or national security concerns, and it applies across most immigration and human rights applications.

How does Article 8 ECHR affect a human rights application?

Article 8 protects the right to respect for private and family life, so in a human rights application, the Home Office must weigh your situation against the public interest and grant leave if refusing the application would be a disproportionate interference with that right.

Can the Home Office still refuse my application if I have family in the UK?

Yes, the Home Office can still refuse an application even where you have family in the UK, but it must consider the strength of your family life, the best interests of any children, and whether refusal would be unjustifiably harsh or disproportionate in your particular case.

What counts as exceptional circumstances in a family or private life case?

Exceptional circumstances are situations where applying the normal Rules and refusing the application would lead to unjustifiably harsh results for you or your family, for example, in serious medical cases, where children have long residence in the UK, or where family life cannot reasonably continue in another country.

Are there any upcoming changes that could affect human rights and Article 8 applications?

Yes, the Government is consulting on an earned settlement system with longer residence periods. It has implemented a comprehensive Part Suitability framework, so people relying on Article 8 should expect stricter suitability checks, possible removal of the 10year long residence route, and a greater need to present detailed evidence of their family and private life.
