Summary of Legal Opinion

Factual and Procedural Background

The judgment, delivered jointly by Judge Lloyd-Jones and Judge Rose (with whom Judge Sales, Judge Hamblen and Judge Richards agree), concerns the correct characterisation of the child element of Universal Credit (“UC”) under United Kingdom legislation, for the purposes of Regulation (EC) No 883/2004 on the coordination of social security systems (the “Coordination Regulation”), as amended. Although the United Kingdom has withdrawn from the European Union, the Coordination Regulation continues to apply by virtue of the Withdrawal Agreement, as implemented domestically by the European Union (Withdrawal) Act 2018.

The Appellant is a national of another EU Member State, resident in The City with a permanent right to reside in the United Kingdom. She applied for UC on 26 July 2017, claiming the standard allowance, a housing costs element, and a child element in respect of her son (the “Child”), who at the relevant times resided with his grandparents in The State. Under section 10(1) of the Welfare Reform Act 2012 (“WRA 2012”) and regulation 4(2) of the Universal Credit Regulations 2013, a claimant is entitled to an amount for each child or qualifying young person for whom they are “responsible”, and a person is responsible only if the child “normally lives” with them. Because the Child lived in The State, it was common ground that, as a matter of domestic law alone, the Appellant was not entitled to the child element of UC, notwithstanding that she otherwise qualified for UC and paid for the Child’s upkeep.

On 1 September 2017, the Respondent decided that the Appellant was entitled to UC from 26 July 2017, awarding the standard allowance and the housing costs element, leaving the child element to be determined. On 8 September 2017 the Respondent accepted that the Appellant had a permanent right to reside in the United Kingdom. On 25 September 2017, knowing that the Child was being educated in The State, the Respondent decided to award the child element and arrears were paid. However, on 17 October 2019, the Respondent revised that decision, concluding that the Appellant was not and had never been entitled to the child element. That revision decision is the subject of the present proceedings.

Following a mandatory reconsideration, the Respondent confirmed on 31 January 2020 that the Appellant was not entitled to the child element from 26 July 2017. The Appellant appealed to the First-tier Tribunal, which on 19 August 2020 allowed the appeal and awarded the child element from 12 September 2017. The Respondent appealed to the Upper Tribunal. In responding to that appeal, the Appellant accepted that the First-tier Tribunal had misapplied the UC Regulations 2013, but argued that the child element was nevertheless payable because it was a “family benefit” under the Coordination Regulation, so that EU law required the Child to be treated as living with her.

On 21 February 2023 the Upper Tribunal allowed the Respondent’s appeal and remade the decision, holding that entitlement to UC from 26 July 2017 was to be calculated without the child element. The Appellant appealed to the Court of Appeal (Judge Lewison, Judge Green and Judge Laing), which on 26 April 2024 dismissed the appeal. On 9 October 2024 the Supreme Court (Judge Reed, Judge Leggatt and Judge Rose) granted permission to appeal. The present Supreme Court judgment dismisses that appeal.

It is common ground that if the Coordination Regulation applies and the child element is a “family benefit” within article 3(1)(j), then: (i) United Kingdom law would be the applicable legislation under article 11; (ii) article 7 would prevent withdrawal of the cash benefit because the Child resides in another Member State; and (iii) article 67 would require the Child to be treated as residing with the Appellant. The central question is therefore whether the child element of UC falls within the category of “family benefits” under article 3(1)(j) of the Coordination Regulation.

Legal Issues Presented

1. Whether the child element of Universal Credit, when considered in the context of the United Kingdom’s UC scheme, is a “family benefit” within the meaning of article 3(1)(j) of the Coordination Regulation, thereby engaging the Regulation’s rules (including articles 7 and 67) and requiring the child element to be payable notwithstanding the Child’s residence in another Member State.
2. Whether, for the purposes of the Coordination Regulation, the child element of UC can or must be treated as a free‑standing benefit, severable from the rest of UC, even though UC is legislatively designed as a single, composite benefit.
3. Whether EU law, particularly the case law of the Court of Justice of the European Union (“CJEU”), recognises an “emerging doctrine of severance” under which different elements of a composite national benefit (such as UC) can be separately classified under different branches of social security in article 3(1) of the Coordination Regulation.
4. Whether, in the circumstances of this appeal and under article 158 of the Withdrawal Agreement (as implemented by section 7A of the European Union (Withdrawal) Act 2018), the Supreme Court should make a reference to the CJEU on the interpretation of the Coordination Regulation and related EU law.

Arguments of the Parties

Appellant's Arguments

• Reliance on EU coordination rules: The Appellant argued that she has a directly effective right under the Coordination Regulation entitling her to the child element of UC. She contended that, for the purposes of that Regulation, her son must be deemed to live with her, thus overriding the residence requirement in regulation 4(2) of the UC Regulations 2013.
• Child element as a family benefit: The Appellant maintained that the child element is a “family benefit” within article 3(1)(j) of the Coordination Regulation. On that basis, article 7 (prohibiting withdrawal of cash benefits because beneficiaries or their family members reside in another Member State) and article 67 (entitlement to family benefits for family members residing in another Member State “as if they were residing” in the competent State) should apply.
• Analogy with Child Tax Credit (CTC): The Appellant submitted that the child element of UC effectively replaced Child Tax Credit, which has been recognised by the CJEU as a family benefit for the purposes of the Coordination Regulation. It was said that the child element shares many characteristics with CTC and should therefore be treated similarly. The fact that many CTC recipients were also on income support or other social assistance benefits did not prevent CTC from being characterised as a family benefit.
• Autonomous EU concepts and Lachheb: Relying on Caisse nationale des prestations familiales v Lachheb, the Appellant argued that the characterisation of a benefit is an autonomous matter of EU law and does not depend on how the benefit is structured or labelled in domestic legislation. Counsel for the Appellant and the supporting intervener argued that the Court of Appeal had wrongly allowed the formal structure of UC under domestic law to dictate the application of the Coordination Regulation, undermining the protection of free movement that the Regulation is intended to secure.
• Severability of the child element: Building on Lachheb, the Appellant contended that the CJEU’s approach in that case demonstrates that discrete components associated with family allowances (such as the “child bonus” in Lachheb) can be separately classified as family benefits, even if they are linked to broader measures. By analogy, the child element of UC should be isolated and characterised on its own merits as a family benefit, regardless of UC’s overall structure.
• Emerging doctrine of severance: The Appellant further argued that the CJEU case law on special non-contributory cash benefits (“SNCBs”), particularly the Annex IIa litigation concerning Disability Living Allowance (“DLA”) and its mobility and care components, reveals an emerging doctrine of severance. According to this argument, different elements within a single benefit can be treated as separate benefits for the purposes of the Coordination Regulation. The Appellant relied especially on Bartlett v Secretary of State for Work and Pensions, where the CJEU accepted that the mobility component of DLA could be regarded as a separate “benefit”.
• Use of Advocate General’s Opinion in CG (Northern Ireland): The Appellant referred to a footnote in the Opinion of Advocate General De la Tour in CG v Department for Communities in Northern Ireland, in which he stated that “universal credit” designates a variety of allowances, some of which may be governed by special EU rules. This was said to support the proposition that elements of UC (such as the child element) can be disaggregated and classified separately.
• Request for a reference to the CJEU: The Appellant invited the Supreme Court to refer the issues concerning the characterisation of the child element and severability to the CJEU under article 158 of the Withdrawal Agreement, so that those questions could be definitively determined at EU level.

Respondent's Arguments

• Child element not a family benefit under article 3(1)(j): The Respondent maintained that the child element of UC is not a “family benefit” within the meaning of article 3(1)(j) of the Coordination Regulation. Consequently, the Coordination Regulation does not apply and the Appellant has no EU-law based entitlement to that element.
• Nature of UC as a single, anti-poverty benefit: It was common ground that UC, viewed as a whole, is an anti-poverty measure aimed at providing a minimum level of income and addresses a wide range of needs, some of which do not correspond to any of the specific risks listed in article 3(1). The Respondent contended that it is UC as a whole, and not its individual elements, that must be characterised for the purposes of the Coordination Regulation.
• Requirement that a social security benefit cover a single listed risk: Counsel for the Respondent argued that, under the CJEU case law, a benefit must be directed at one (and only one) of the risks listed in article 3(1) in order to fall within the coordination regime. Since UC is a composite scheme with multiple objectives and elements, it does not satisfy this requirement and cannot be brought within article 3(1) by isolating one component of it.
• Rejection of severance: The Respondent rejected the contention that elements of UC, including the child element, can be severed and separately classified under different branches of article 3(1). The structure of UC in the WRA 2012 shows that it is conceived as a unitary benefit whose amount is calculated by reference to several factors; a claimant cannot claim any element in isolation. This, the Respondent submitted, means that EU law must characterise the benefit as it actually exists in domestic law.
• Distinction between UC and Child Tax Credit: The Respondent argued that Child Tax Credit, while indeed a family benefit, was a free‑standing benefit in domestic law and therefore not comparable to the child element within UC. The integration of the child element into UC is substantive, not merely presentational, and cannot be treated as if UC were simply a bundle of separate benefits.
• Limits of Lachheb and autonomous concepts: While accepting that classifications under the Coordination Regulation are matters of EU law and do not depend on national labels, the Respondent contended that Lachheb does not support the Appellant’s argument. In that case the CJEU simply classified the “child bonus” as a family benefit on its own terms; it did not hold that components of a single, unified benefit must be severed and separately characterised.
• No general doctrine of severance from SNCB case law: The Respondent argued that the CJEU’s treatment of DLA and Annex IIa in the Annex IIa case and in Bartlett was a pragmatic response to the particular structure of Disability Living Allowance and the wording of Annex IIa, not a general principle that composite benefits should be disaggregated. In any event, DLA’s mobility and care components were legislatively defined as separate entitlements, unlike the elements of UC.
• Opposition to reference to the CJEU: The Respondent opposed a reference under article 158 of the Withdrawal Agreement on two grounds: (i) that the relevant law to be applied is that in force on 17 October 2019, when the impugned decision was taken, at which time EU law applied via the European Communities Act 1972 and Part Two of the Withdrawal Agreement was not yet in force; and (ii) article 158 applies only to cases commenced at first instance within eight years of the end of the transition period, whereas these proceedings were instituted on 17 February 2020, before that period ended, so the power to make a reference under article 158 was not engaged.

Table of Precedents Cited

Precedent	Rule or Principle Cited For	Application by the Court
Hughes v Chief Adjudication Officer, Belfast (Case C-78/91) [1992] CMLR 490	(i) “Social assistance” under the Coordination Regulation is narrowly defined and involves individual assessment of personal needs and discretionary power to take account of circumstances beyond those set in legislation; (ii) family credit performs a dual function (incentivising work and meeting family expenses) and is a family benefit by virtue of its function of meeting family expenses.	Used to distinguish social security benefits from social assistance (supporting the conclusion that UC and its child element satisfy the “objective criteria” test) and to show that, even where a benefit has multiple purposes, it may nevertheless fall within a specific category (such as family benefits) once it is within the scope of the Regulation. The Court emphasised, however, that this case does not undermine the requirement that benefits must first fall within one of the listed branches of article 3(1) and does not support a doctrine of severance of components of a single benefit.
De Cuyper v Office national de l'emploi (Case C-406/04) [2007] ICR 317; [2006] 3 CMLR 44	(i) Benefits are of the same kind for classification purposes when their purpose, object, basis of calculation and conditions for grant are identical, regardless of formal characteristics; (ii) classification must consider “the risk covered”, e.g. an unemployment benefit covers the risk of loss of income due to involuntary unemployment while the person retains capacity for work.	Cited to support the need to analyse the substantive characteristics and risk covered by a benefit when determining whether it falls within the Coordination Regulation and, if so, under which branch of article 3(1). Used to reinforce the requirement that a coordinated benefit must relate to one of the listed risks and to explain how that principle was applied to unemployment allowances in that case, by analogy to the present classification exercise.
Stewart v Secretary of State for Work and Pensions (Case C-503/09) [2012] PTSR 1; [2012] 1 CMLR 13	Regulation 1408/71 (predecessor to the Coordination Regulation) does not establish a common social security system but coordinates different national schemes. Member States retain power to organise their own social security systems, subject to EU law; the Regulation provides conflict‑of‑laws rules designating the applicable legislation.	Quoted to emphasise that the Coordination Regulation is a coordinating, not harmonising, instrument. The Court used this to underline that EU law respects the structure of national systems such as UC and that Member States retain broad discretion over the design of their benefits, provided they comply with EU non‑discrimination rules.
Tolley v Secretary of State for Work and Pensions (Case C-430/15) [2017] 1 WLR 1261	(i) Explanation of the principle of “single applicable legislation” under the Coordination Regulation; (ii) distinction between “sickness benefits” and “invalidity benefits” and the method of classifying Disability Living Allowance (“DLA”) care component as a sickness benefit.	The Court relied on the Advocate General’s explanation (para 65) of how designating one Member State’s legislation as applicable entails subjection to that State’s social security scheme alone, and on the CJEU’s judgment (paras 57–58) confirming that Title II of Regulation 1408/71 forms a complete system of conflict rules. This supported the discussion of the “single applicable legislation” principle and the need to classify benefits under one of the listed branches of article 3(1).
Hoeckx v Centre Public d'Aide Sociale de Kalmthout (Case 249/83) [1987] 3 CMLR 638	(i) Distinction between benefits within and outside Regulation 1408/71 depends on constituent elements—purpose and conditions—not national classification; (ii) the list of social security “risks” covered is exhaustive, and legislation must cover at least one of those risks to fall within the Regulation.	Treated as an authoritative statement that a benefit must cover one of the listed risks in article 3(1) of the Coordination Regulation, and that the list is exhaustive. The Court rejected the Appellant’s attempt to downplay this condition, reaffirming that UC as a whole is not directed at a single listed risk and therefore cannot be a coordinated social security benefit. Hoeckx was also cited (together with later cases) to show that formal labels in national law are not determinative.
Caisse d'Assurance Retraite et de la Santé au Travail d'Alsace‑Moselle v SJ (Case C-769/18) ECLI:EU:C:2020:203	A benefit is a “social security benefit” for the purposes of the Coordination Regulation if: (i) it is granted on the basis of a legally defined position without any individual and discretionary assessment of personal need; and (ii) it relates to one of the risks listed in article 3(1).	Cited as the modern formulation of the two cumulative conditions for a coordinated social security benefit. The Court accepted that UC and its child element satisfy the first condition (objective criteria, no individual needs assessment), but held that the second condition is not met by UC as a whole, because it is not directed at a single listed risk.
Ministre de l'Action et des Comptes Publics v Dreyer (Case C-372/18) ECLI:EU:C:2019:206	Confirms that the approach in Hoeckx to classification and the exhaustive nature of the list of risks remains authoritative.	Referenced to reinforce the continuing authority of Hoeckx and to rebut the suggestion that later CJEU case law has diluted the requirement that a benefit must fall under a single risk listed in article 3(1).
Newton v Chief Adjudication Officer (Case C-356/89) [1992] 1 CMLR 149	Mobility allowance had a “two‑fold function” and could be classified as a social security benefit when claimed by employed or self‑employed persons already covered by the relevant State’s social security system, but not necessarily for other categories of beneficiaries.	Used to clarify that Newton does not undermine the principle in Hoeckx. The case concerned classification of the same benefit for different classes of people, not severance of elements within a single benefit. It provided no support for a doctrine of severance of UC elements.
Caisse nationale des prestations familiales v Lachheb (Case C-177/12) ECLI:EU:C:2013:689	(i) The classification of benefits under the Coordination Regulation depends on their purpose and conditions, not on national labels or formal mechanisms (e.g. tax law); (ii) a “child bonus” paid through a tax system, linked to entitlement to family allowances, can be a “family benefit” because it is a public contribution to the family budget, alleviating financial burdens of maintaining children.	The Appellant relied on Lachheb to argue for separate classification of the child element of UC. The Court accepted the general principle that autonomous EU concepts do not depend on national labels, and that formal mechanisms of payment are irrelevant. However, it rejected the contention that Lachheb establishes a rule that components of a single domestic benefit must be severed. The Court pointed out that it was unclear that the “child bonus” in Lachheb functioned as an integrated component of the family allowance in the same way the child element forms part of UC, and that the CJEU simply answered the narrow question put to it.
Offermanns (Case C-85/99) ECLI:EU:C:2001:166; [2001] ECR I‑2285	A Member State cannot determine the applicability of the Coordination Regulation by classifying a benefit in its own legislation; EU law looks to the benefit’s substantive characteristics.	Cited, together with OD INPS, to support the proposition that national labels and formal classifications do not control whether a measure falls under the Coordination Regulation. This supported acceptance of the Appellant’s general point about autonomous EU concepts but did not assist the argument for severance of UC elements.
OD Istituto Nazionale della Previdenza Sociale (INPS) (Case C-350/20) [2022] 1 CMLR 32	Reiterates that purely formal characteristics, including classification under national law, are not decisive for the classification of a benefit under the Coordination Regulation.	Used alongside Offermanns to reaffirm that EU law looks at the substantive nature and purpose of a benefit, rather than domestic labelling, when deciding whether the Coordination Regulation applies.
CG v Department for Communities in Northern Ireland (Case C-709/20) [2021] 1 WLR 5919	The CJEU described UC as a cash subsistence benefit, funded by taxation, subject to means‑testing, and intended to replace various former social benefits (including income‑based jobseeker’s allowance, income‑related employment and support allowance, income support, working tax credit, child tax credit and housing benefit).	The Court drew on the CJEU’s description to characterise UC as a broad, tax‑funded, anti‑poverty measure rather than as a traditional social security benefit covering a single listed risk. This supported the conclusion that UC as a whole cannot be treated as a coordinated social security benefit under article 3(1).
European Commission v United Kingdom (Case C-308/14) [2016] 1 WLR 5049 (“Commission v UK: CTC”)	Held that child benefit and Child Tax Credit in the United Kingdom were “family benefits” within article 3(1)(j) and article 1(z) of the Coordination Regulation.	Relied on to establish that Child Tax Credit was recognised as a family benefit under the Coordination Regulation. The Court distinguished that position from the present case, noting that CTC was a free‑standing benefit, whereas the child element of UC is structurally integrated into a unitary UC scheme.
R (Salvato) v Secretary of State for Work and Pensions [2021] EWCA Civ 1482; [2022] PTSR 366	Detailed description of the structure and operation of UC as a single benefit comprising a standard allowance and various elements (including child and housing), paid monthly in arrears, and designed to adjust flexibly to changes in claimants’ circumstances.	The Supreme Court adopted Judge Andrews’ description of UC, highlighting that UC is a single monthly payment, calculated by reference to several elements, and that the elements cannot be separated out or claimed independently. This supported the conclusion that the child element is not a separate benefit capable of independent characterisation under the Coordination Regulation.
Jauch v Pensionsversicherungsanstalt der Arbeiter (Case C-215/99) [2001] ECR I-1901	Interpreted the criteria for special non-contributory cash benefits (“SNCBs”) under article 4(2a) of Regulation 1408/71, prompting a revision of the list of SNCBs in Annex IIa.	Mentioned to explain the historical background to amendments of Annex IIa and the classification of SNCBs. Used as part of the context for the Commission’s challenge to the contents of Annex IIa in the Annex IIa case, showing how SNCBs differ from ordinary coordinated social security benefits and that they form a distinct category.
Leclere v Caisse nationale des prestations familiales (Case C-43/99) [2001] ECR I-4265	Clarified the conditions for classifying benefits as SNCBs and provided authority for treating entries in Annex IIa as severable elements.	Cited via the Advocate General in the Annex IIa case to support the idea that individual benefits listed in Annex IIa can be annulled without annulling the entire Annex, and that individual entries are severable. This was part of the background to later litigation on Disability Living Allowance.
Commission of the European Communities v Parliament and Council of the European Union (Case C-299/05) [2007] ECR I-8695 (the “Annex IIa” case)	(i) Reviewed the lawfulness of listing certain benefits, including Disability Living Allowance (“DLA”), attendance allowance and carer’s allowance, as SNCBs in Annex IIa; (ii) held that the care component of DLA is a sickness benefit and therefore could not be listed as an SNCB; (iii) addressed whether entries in Annex IIa could be partially annulled and used temporal limitation of annulment to avoid immediate exportability issues.	The Court used this case to show that the CJEU had treated the mobility and care components of DLA differently because of the particular structure of DLA and the mechanics of Annex IIa, not because of a general doctrine of severance. The opinion of Advocate General Kokott was referenced to show that, although she recognised that Annex IIa entries were severable, the CJEU ultimately used temporal limitation of the effects of annulment rather than reading the entry as partially valid. This context was important to distinguish that special SNCB regime from the classification exercise in respect of UC.
Bartlett v Secretary of State for Work and Pensions (Case C-537/09) [2012] PTSR 535	Held that the mobility component of DLA could itself be regarded as a “benefit” and that the reference in Annex IIa to DLA should be understood as referring only to the mobility component, following the Annex IIa case.	The Appellant cited Bartlett as evidence that the CJEU treats components of a benefit as severable. The Court rejected this as a basis for a general severance doctrine, explaining that Bartlett was a pragmatic solution to the particular problem created by Annex IIa and that DLA’s components were legislatively separate in a way that UC’s elements are not.

Court's Reasoning and Analysis

The Court began by setting out the legal framework of the Coordination Regulation and its continued application in the United Kingdom under the Withdrawal Agreement. It emphasised that EU law draws a “fundamental distinction” between social security benefits, which fall under the Coordination Regulation, and social assistance benefits, which are governed by other instruments. Social security benefits, under article 3(1), must relate to specific branches of social security (such as sickness, unemployment, or family benefits), whereas social and medical assistance are expressly excluded by article 3(5)(a).

The Court reiterated that the Coordination Regulation is a coordinating measure, not a harmonising one. Relying on the recitals and CJEU case law, it explained that the Regulation:

• respects the “special characteristics of national social security legislation”;
• aims to subject persons moving within the EU to the social security scheme of only one Member State, to avoid gaps and overlaps; and
• provides a complete and uniform system of conflict rules, designating the applicable national law and, in some cases, determining which State is “competent” to pay a particular benefit.

Under article 4, discrimination based on nationality is prohibited, but residence-based conditions are addressed through the detailed provisions of the Regulation, notably article 7 (waiving of residence rules) and article 67 (entitlement to family benefits for family members residing in another Member State).

Two Conditions for a Coordinated Social Security Benefit

The Court then turned to the test for determining whether a benefit falls within the scope of article 3(1) of the Coordination Regulation. Following SJ and earlier case law:

1. The benefit must be granted on the basis of a “legally defined position” and objective criteria, without any individual and discretionary assessment of the claimant’s personal needs (otherwise it is social assistance).
2. The benefit must relate to one of the specific risks listed in article 3(1). The list of risks is exhaustive, and a benefit must be directed at one (and only one) such risk to be a coordinated social security benefit.

It was common ground that both UC as a whole and the child element individually satisfy the first condition: entitlement is determined by statutory criteria and means tests, not discretionary assessment of individual need. The central dispute concerned the second condition.

The Court accepted the Respondent’s submission that the benefit must be directed at one specific risk listed in article 3(1). This requirement follows from the exhaustive nature of the list of risks and is important because different branches (such as sickness, unemployment, and family benefits) are subject to different coordination rules. The Court relied on Hoeckx and other CJEU authority to confirm that:

• legislation must at least cover one of the specified risks to fall within the Regulation; and
• a benefit that does not fit any listed branch is not a coordinated social security benefit, even if it provides a legally defined entitlement.

The Nature and Structure of Universal Credit

The Court then examined the legislative design of UC under the WRA 2012. It noted that:

• section 1(1) establishes UC as a single benefit “payable in accordance with” Part 1 of the Act;
• section 1(3) provides that the amount of an award is calculated by reference to (a) a standard allowance; (b) an amount for responsibility for children or young persons; (c) an amount for housing; and (d) amounts for other particular needs or circumstances;
• the claimant must make a claim for UC; there is no provision for a separate claim for any particular element; and
• the “unitary nature” of UC is “readily apparent”, with all elements feeding into a single monthly payment that flexibly adjusts to earnings and changes in circumstances.

Adopting the description from Salvato, the Court emphasised that UC is designed around:

• a monthly assessment period,
• a single monthly payment, and
• integration of all relevant elements (including childcare costs, housing and child responsibility) into one calculation.

Responsibility for a child has further consequences in the UC scheme, such as affecting housing costs calculations, work allowances, and work conditionality. This confirmed, in the Court’s view, that the child element is deeply embedded in a broader income‑maintenance and anti‑poverty scheme.

It was common ground that UC as a whole is an anti‑poverty measure and “cannot be a coordinated social security benefit” within article 3(1). It is aimed at ensuring a minimum income and addresses a wide variety of needs, some unrelated to any single risk identified in article 3(1). The Appellant accepted this. Her case depended on treating the child element as a separate benefit, detachable from the rest of UC.

Whether the Child Element Can Be Treated as a Separate Family Benefit

The Court recognised that, if the child element of UC were examined in isolation, it would be “clearly arguable” that it constitutes a family benefit within article 3(1)(j). It is linked to responsibility for a child and could be seen as contributing to the costs of raising children. The fact that it is means‑tested does not, by itself, prevent it from being a family benefit rather than social assistance, given the CJEU’s narrow definition of “social assistance”.

However, the Court considered that the decisive issue was whether EU law requires, or even permits, the child element to be treated as a free‑standing benefit for coordination purposes. On this question, it rejected the Appellant’s arguments.

Analogy with Child Tax Credit (CTC)

The Appellant’s first major submission was that the child element of UC replaced Child Tax Credit, which had been recognised as a family benefit under the Coordination Regulation. While acknowledging that CTC and the child element share some characteristics, and that CTC was indeed treated as a family benefit in Commission v UK: CTC, the Court held that this analogy was not determinative.

The Court’s “short answer” was that CTC was a free‑standing benefit in domestic law, whereas the child element is not. Instead, the child element is one factor in the calculation of the amount of UC—a fully integrated part of a composite scheme. There was no allegation of abuse in the design of UC, and the Court accepted that the integration was a matter of substance, not form. Accordingly, it is UC itself, not the child element in isolation, that must be characterised under article 3(1).

Autonomous EU Concepts and the Significance of Lachheb

The Court accepted the general proposition, stressed by the Appellant and the intervener, that:

• the interpretation of concepts in the Coordination Regulation (such as “family benefits”) is an autonomous matter of EU law; and
• Member States cannot determine whether a measure falls within the Regulation simply by the labels or formal structures they adopt.

Nonetheless, the Court held that Lachheb does not justify treating the child element of UC as severable. In Lachheb, the CJEU classified a “child bonus” administered through tax law as a family benefit based on its purpose—contributing to the family budget and alleviating child‑related expenses. The Court pointed out that:

• it was not clear that the “child bonus” was integrated into the underlying family allowance in the same way UC’s child element is integrated into UC;
• the referring court’s questions did not ask whether the bonus followed the classification of the family allowance; and
• the CJEU therefore did not need to address the relationship between components and underlying benefits, nor did it articulate any principle that components of a composite benefit must be severed.

Rather, Lachheb is seen as a straightforward application of the established approach—focusing on purpose and conditions, not formal classification—to a benefit that, on its own terms, was plainly a family benefit.

Rejection of an “Emerging Doctrine of Severance”

The Appellant argued that CJEU case law—particularly on SNCBs and DLA—reveals an emerging doctrine of severance under which different elements within a single benefit can be treated as separate for Coordination Regulation purposes. The Court examined this argument and rejected it.

It noted that Newton and Hughes do not support such a doctrine. Those cases dealt with:

• the classification of the same benefit (mobility allowance, family credit) for different categories of claimants or different functions; and
• how a benefit, once clearly within the scope of the Regulation, is allocated to one of the listed branches, not whether internal components must be split.

Turning to the SNCB line of authority, the Court traced the history of the creation of SNCBs and the litigation over Annex IIa. It observed that:

• SNCBs form an intermediate category of benefits with characteristics of both social security and social assistance and are coordinated but not exportable;
• Member States may list qualifying benefits in Annex X (formerly Annex IIa) to classify them as SNCBs; and
• the United Kingdom had not listed UC or any of its elements in Annex X, and SNCBs were not directly relevant to the Appellant’s claim.

The Court then analysed the Annex IIa case and Bartlett. It noted that:

• DLA comprises two components—mobility and care—and legislation explicitly allows entitlement to one or both components, under separate statutory criteria;
• in the Annex IIa case, the CJEU concluded that the care component was a sickness benefit and therefore could not lawfully be included as an SNCB, whereas the parties were agreed that the mobility component could validly be so included;
• because DLA as a whole had been listed in Annex IIa, the Advocate General opined that the entry must be annulled in its entirety, and that partial annulment would undermine legal certainty; and
• the CJEU resolved the problem by annulling the entry but maintaining its effects temporarily for the mobility component, thereby giving time to correct the Annex.

In Bartlett, the CJEU later held that the mobility component could be treated as a “benefit” on its own, effectively reading the Annex IIa reference to DLA as referring only to that component. The Court here characterised this as a pragmatic solution to a specific drafting and temporal‑effect problem, grounded in the particular structure of DLA and the special SNCB regime.

The Supreme Court stressed several reasons why this case law does not justify severance in relation to UC:

• DLA’s components are legislatively distinct, with explicitly separate entitlements, whereas UC’s elements are simply factors in calculating a single benefit award and cannot be claimed separately;
• the CJEU’s approach in the SNCB cases was concerned with the effect and interpretation of Annex IIa/X, not with laying down a general principle that elements of any composite benefit can be disaggregated; and
• there is no CJEU authority stating that elements of a benefit like UC must be separately classified under different branches of article 3(1).

The Court agreed with Judge Green’s assessment in the Court of Appeal that both the policy and structure of the Coordination Regulation militate against recognition of a general doctrine of severance. The Regulation is detailed and complex; if such a doctrine were intended, it would likely have been clearly articulated in the legislative text. A general doctrine would also risk fragmenting national benefits into multiple EU-classified components, potentially creating “stand‑alone legal rights” not envisaged by the Regulation.

Conclusion on Classification of the Child Element

Having reviewed the structure of UC, the applicable EU law principles, and the relevant case law, the Court concluded that:

• UC is a composite, anti‑poverty, income‑maintenance scheme, not directed at any single risk listed in article 3(1);
• it is UC as a whole, not its internal elements, that constitutes the relevant “benefit” for the purposes of the Coordination Regulation;
• EU law does not require or authorise severance of the child element from the rest of UC for classification purposes; and
• therefore, UC (including its child element) does not fall within any of the branches of social security listed in article 3(1), and the child element cannot be treated as a separate “family benefit” under article 3(1)(j).

It followed that the Coordination Regulation did not apply to the child element of UC and that articles 7 and 67 could not be invoked to deem the Child as living with the Appellant or to override domestic residence rules in regulation 4(2) of the UC Regulations 2013.

Reference to the CJEU under Article 158 of the Withdrawal Agreement

The Appellant invited the Court to refer questions to the CJEU under article 158 of the Withdrawal Agreement, as implemented by section 7A of the EU (Withdrawal) Act 2018. The Respondent opposed this, advancing two arguments on the Court’s power to refer:

1. By virtue of section 12(8)(b) of the Social Security Act 1998, the relevant law is that in force on 17 October 2019, when the Respondent’s decision was taken. At that time, EU law applied through the European Communities Act 1972, and Part Two of the Withdrawal Agreement (to which article 158 relates) was not yet in force. Thus, no question arises concerning the interpretation of that Part in this case.
2. Article 158(1) provides that references are available in cases commenced at first instance “within 8 years from the end of the transition period”. This reflects a choice that the article applies only to proceedings instituted after the end of the transition period. The present proceedings were instituted on 17 February 2020, before the transition period ended; accordingly, article 158 was argued not to apply.

The Supreme Court held that, in light of its clear conclusion on the substantive issues, it was unnecessary, as a matter of discretion, to make a reference to the CJEU. The Court therefore declined to refer any questions. It expressly left open the questions raised about the scope of its power to make references under article 158, indicating that those issues would need to be resolved in a more appropriate future case.

Holding and Implications

The Supreme Court held that the child element of Universal Credit is not a “family benefit” within the meaning of article 3(1)(j) of the Coordination Regulation and cannot be treated as a free‑standing benefit separate from Universal Credit as a whole.

Because UC, considered in its statutory structure and purpose, is an integrated, anti‑poverty, means‑tested benefit addressing multiple needs and not confined to a single listed risk under article 3(1), the Coordination Regulation does not apply to it. There is no basis in EU law for severing the child element and classifying it independently as a coordinated family benefit. Consequently, articles 7 and 67 of the Coordination Regulation cannot be relied upon to export the child element of UC or to deem the Child as residing with the Appellant for UC purposes.

The Court therefore ordered that the appeal be DISMISSED. The result is that the Respondent’s decision of 17 October 2019, revising the Appellant’s award of UC so as to exclude the child element from 26 July 2017, stands. The Appellant remains entitled to UC standard allowance and housing costs, but not to the child element in respect of the Child residing in another Member State.

The Court declined to make a reference to the CJEU under article 158 of the Withdrawal Agreement, leaving unresolved, for future cases, the precise scope of the United Kingdom courts’ power to refer under that provision.

The judgment’s direct implication is confined to the parties: the Appellant cannot obtain the UC child element on the basis of EU coordination rules. The Court did not purport to establish any new category of benefit or alter the general EU-law test for distinguishing social security from social assistance. Instead, it applied established principles to the particular design of UC and rejected the notion of a general doctrine of severance for composite benefits. No broader legislative or systemic reforms were mandated or discussed.
