Two-Child Limit Exceptions: Justifying Differential Treatment Between Non-Consensual Conception, Adoption and Non-Parental Care in Universal Credit

Case: LMN & Anor, R (On the Application Of) v Secretary of State for Work and Pensions
Citation: [2026] EWCA Civ 846
Court: Court of Appeal (Civil Division)
Date: 2 July 2026
Judges: Lord Justice Lewis; Lady Justice Andrews; Sir Stephen Cobb (President of the Family Division)

1. Introduction

This appeal concerned the design and operation of exceptions to the former “two-child limit” in Universal Credit (UC)—a limit restricting the UC child element to a maximum of two children, subject to defined exceptions. Although the two-child limit was repealed from 5 April 2025, the Court addressed the lawfulness (under the European Convention on Human Rights) of the scheme as it stood before repeal.

The appellants (two women, referred to by initials in the judgment) were survivors of extreme domestic and sexual violence. Each had children conceived through non-consensual intercourse in abusive relationships. Their claims did not challenge individual benefit decisions as such, but instead attacked the compatibility of the regulatory scheme that:

• fully exempted adopted children and children cared for under non-parental caring arrangements from the two-child “ordering” rules (so they did not count towards the cap at all), while
• limiting the NCC exception to circumstances where the third or subsequent child (by birth order) was NCC.

The practical consequence was that a mother whose first two children were NCC could still be refused the child element for a later consensually conceived child; whereas other configurations (e.g., a later NCC third child) could attract the exception.

Parties and positions

• Appellants: LMN and EFG (identified by initials), UC claimants and mothers with children conceived in part through non-consensual intercourse.
• Respondent: Secretary of State for Work and Pensions.

Key legal issue

Whether regulations 24A–24B of, and Schedule 12 to, the Universal Credit Regulations 2013 (the “2013 Regulations”) unlawfully discriminated contrary to Article 14, read with Article 8 and/or Article 1 of the First Protocol (A1P1), by failing to extend the NCC exception (or an equivalent) to mothers whose earlier children were NCC but whose third/subsequent child was consensually conceived—and by treating them differently from adoptive parents and non-parental carers.

2. Summary of the Judgment

The Court of Appeal dismissed the appeal and upheld the High Court’s conclusion that the impugned regulatory scheme was compatible with Article 14.

In outline, the Court held that:

• the claim fell within the “ambit” of Article 8 and probably A1P1;
• the alleged differential treatment was linked to a “status” (being a mother of non-consensually conceived child/children);
• comparators (adoptive/non-parental carers; and mothers whose third child is NCC) were arguably not truly analogous, but the Court assumed analogy arguendo;
• the scheme’s differential treatment was objectively justified and proportionate in pursuit of legitimate aims consistent with the two-child limit’s rationale;
• any alleged errors by the High Court on proportionality and “family law” considerations were immaterial because the Court of Appeal conducted the proportionality assessment afresh—and, in any event, it found no such errors.

3. Analysis

3.1 Statutory and regulatory architecture

Primary legislation: The Welfare Reform Act 2012 created UC (section 1). At the relevant time, section 10(1A) capped the UC child element to a maximum of two children, subject to exceptions set by regulations (section 10(4)).

Responsibility test: Under regulation 4 of the 2013 Regulations, a claimant is responsible for a child who normally lives with them.

Two-child limit implementation and exceptions:

• Regulation 24A governed when the child element was “available” where the maximum would otherwise be exceeded.
• Schedule 12 set out exceptions, including:
  • multiple births (para 2),
  • adoptions (para 3),
  • non-parental caring arrangements (para 4),
  • non-consensual conception (para 5).
• Regulation 24B set “ordering” rules by birth date; critically, regulation 24B(2A) required that children within the adoption/non-parental care exceptions be disregarded when determining order—effectively removing them from the cap calculation.

The design difference mattered: adoption/non-parental care could attract the child element irrespective of where the child sat in chronological birth order; NCC could not.

3.2 Precedents cited and their influence

(a) R (SC) v Secretary of State for Work and Pensions [2021] UKSC 26; [2022] AC 223

This was the foundational authority on the two-child limit itself. The Court of Appeal treated SC as establishing that the two-child limit pursued legitimate aims and was compatible with Article 14, despite disproportionate impact on women.

The Court of Appeal extracted from SC the two “mischiefs” the limit addressed (as quoted in the judgment):

• reducing welfare expenditure to address fiscal deficit; and
• addressing perceived unfairness of unlimited state-backed income increases for additional children compared with working families.

Influence: SC supplied both (i) the accepted legitimacy of the overarching policy and (ii) the analytical lens for “very weighty reasons” where sex discrimination is engaged (the “suspect ground” discussion). The present case became a question of whether the exception design undermined Convention compatibility.

(b) Thlimmenos v Greece (2001) EHRR 15

Thlimmenos stands for a second modality of discrimination: treating materially different situations the same, without objective justification. The High Court had characterised part of the claim as a Thlimmenos-type argument (mothers with NCC children should not be treated the same as mothers with consensually conceived children because “choice” is fundamentally different).

Influence: The Court of Appeal acknowledged the Thlimmenos concept but resolved the case through justification/proportionality, effectively holding that even if a failure-to-differentiate complaint was made out, the line drawn by the regulations was justified by the scheme’s aims and by the “choice at the time of conception of the additional child” rationale.

(c) Bank Mellat v Her Majesty's Treasury (No 2) [2014] AC 700

Bank Mellat provides a structured proportionality framework (commonly expressed as: legitimate aim; rational connection; less intrusive means; fair balance). The Court of Appeal signposted that four-stage approach as the relevant tool for objective justification under Article 14.

Influence: The Court’s justification analysis tracks these steps, particularly in separating (i) the adoption/non-parental care exception’s economic logic (avoiding state care costs) from (ii) the NCC exception’s fairness logic (lack of choice at conception).

(d) Shvidler v Secretary of State for Foreign, Commonwealth and Development Affairs [2025] UKSC 30; [2026] AC 607

Shvidler addressed whether an appellate court should (i) reassess proportionality itself or (ii) review the lower court’s proportionality evaluation more deferentially. The Court of Appeal treated Shvidler as decisive on its own role.

Influence: The Court held it should perform a fresh proportionality assessment because:

• this was a challenge to secondary legislation (where senior courts’ constitutional responsibility is “more acute”);
• it was a challenge to a general rule of wide application (not merely case-specific balancing); and
• there was high societal importance in how a vulnerable group (survivors of domestic/sexual violence) is treated by welfare rules.

This part of the judgment is significant beyond UC: it reinforces that in human rights challenges to generally applicable subordinate legislation, an appellate court may be expected to “own” the proportionality decision rather than merely police the first-instance reasoning.

(e) C v Secretary of State for Work and Pensions (Equality and Human Rights Commission intervening) [2018] EWHC 864 (Admin); [2018] 1 WLR 5425

This case explained the history of amendments to adoption and non-parental caring exceptions. Earlier versions irrationally limited the exception to cases where the adopted/cared-for child was the third or subsequent child. The scheme was amended so such children are disregarded for ordering purposes.

Influence: The Court of Appeal used this context to underline that the adoption/non-parental care exception is structurally different: it is designed to remove a disincentive to taking responsibility for children otherwise likely to become state responsibility—hence the disregard in regulation 24B(2A).

3.3 Legal reasoning (Article 14 structure applied)

(1) Ambit

The Court accepted the complaint fell within the ambit of Article 8 and probably A1P1 (consistent with SC): UC rules affect the practical enjoyment of family life and, for adult claimants, may engage “possessions” where an entitlement exists.

(2) Differential treatment, comparators, and “status”

The Court accepted “status” (mother of an NCC child/children) but expressed doubt about the strength of the comparators:

• Adoptive parents and non-parental carers are not biological parents and do not bear parental responsibility by default; they assume responsibility for another’s child. The Court emphasised the legal distinction by reference to sections 2 and 3 of the Children Act 1989 (parental responsibility).
• Mothers with two consensually conceived children who then have an NCC third child were not seen as relevantly similar to mothers whose first two children were NCC and whose later child was consensual, because at the point of the third child’s conception, one group lacks choice and the other does not.

Nevertheless, the Court assumed analogy and proceeded to justification, thereby making the holding robust against disputes on comparator selection.

(3) Objective justification and proportionality

The Court’s justification analysis split into two distinct exception rationales.

(a) Adoption and non-parental caring exceptions: “avoid discouragement” and “avoid state cost”

• Legitimate aim: Prevent UC from discouraging people from adopting or taking non-parental responsibility for children who might otherwise require local authority care (implying public cost and child welfare concerns).
• Rational connection: A full disregard from ordering rules removes the financial disincentive (including future disincentive if the carer later has biological children).
• Less intrusive means: The Court saw no alternative that would achieve the same aim with less interference.
• Fair balance: The exception was proportionate because it aligns with, rather than undermines, the two-child limit’s fiscal logic: it reduces the risk of transferring costs from UC to the care system.

Crucially, the Court treated the appellants’ position as different in kind: they are not being incentivised to undertake care that would otherwise be borne by the state; they are biological parents enlarging their family through a later consensual conception. On this account, the “very weighty reasons” required (to the extent sex discrimination analysis applied) were met by the strong economic-structural justification for the adoption/non-parental care carve-out.

(b) NCC exception: fairness anchored to “choice at the time of conception of the additional child”

The Court accepted that “harsh economic logic” could have withheld any NCC exception. But it held the NCC exception itself is a proportionate recognition of fairness: where the third (or later) child is conceived without consent, the mother lacked choice at the moment when the cap would otherwise operate.

However, it was equally legitimate to limit the exception to that scenario and not extend it to a later consensual child born to a mother whose earlier children were NCC:

• the point-in-time focus (“circumstances at the time of conception and birth of the additional child”) meant that where the later child was consensually conceived there remained an element of choice;
• extending the exception would cut against the core policy of fixing a cap; and
• the mother’s tragic history did not transform the later consensual conception into the same category as non-consensual conception for exception design purposes.

Accordingly, the Court held it was proportionate to draw the line where the regulations drew it.

(4) Sex as a “suspect ground” and “very weighty reasons”

The Court assessed proportionality on the appellants’ premise that sex-based discrimination principles were in play, referencing the “suspect ground” approach discussed in SC. It then added two observations:

• the relevant differential treatment was between groups of women rather than between women and men; and
• there was no clear evidential basis to infer that the exception-design difference (as opposed to the overall two-child limit) disproportionately disadvantaged women as against men.

Even so, the Court concluded the “very weighty reasons” threshold (if applicable) was satisfied.

(5) Unincorporated international law (CEDAW)

The Court rejected reliance on the United Nations Convention on the Elimination of All Forms of Discrimination against Women as a free-standing source of rights, consistent with SC. It also found no demonstrated interpretive pathway by which the cited CEDAW provisions would alter the Convention analysis in this specific welfare-exceptions dispute.

3.4 Grounds 2 and 3 (proportionality duty and “family law”)

Because the Court undertook a fresh proportionality assessment, any alleged first-instance error was not material. In any event, the Court found:

• the High Court did not abdicate proportionality review; its references to “fairness” and the institutional limits of courts were part of its reasons for upholding the measure, not a refusal to adjudicate; and
• it was not impermissible to note that expanding exceptions for biological mothers would “touch” parental responsibility principles—the point was relevant context rather than a determinative legal bar.

4. Impact

4.1 Doctrinal impact (welfare discrimination challenges)

The judgment reinforces that, once the legitimacy of a broad welfare cap is upheld (here via SC), challenges to the architecture of exceptions face a high hurdle. The Court accepted that exceptions can embody both:

• economic-structural logic (adoption/non-parental care: avoiding state care costs and disincentives), and
• targeted fairness logic (NCC: lack of choice at the relevant conception),

and that limiting an exception to the specific mischief it addresses can itself be part of proportionality.

4.2 Practical and policy impact

Although the two-child limit has been repealed from 5 April 2025, the decision matters for:

• historic entitlement periods and any remaining disputes about past UC awards;
• design of exceptions in future welfare schemes, especially where government differentiates between groups for mixed fiscal and protective reasons; and
• litigation strategy: challenges may need stronger evidence on comparator analogy and on sex-disparate impact attributable to the exception design itself (not merely to the underlying cap).

4.3 Public law / appellate review impact

The appellate-method analysis is likely to be cited beyond welfare law. The Court’s reliance on Shvidler signals that where secondary legislation of broad effect is attacked on Convention proportionality grounds, appellate courts may take responsibility for the full proportionality evaluation, rather than applying a restrained “review of the review”.

5. Complex Concepts Simplified

• Article 14 (non-discrimination): Not free-standing; it applies only “within the ambit” of another Convention right (here, family life and/or possessions).
• “Ambit”: A relatively low threshold—whether the subject matter is sufficiently linked to a Convention right.
• Comparator / analogous situation: To show discrimination, claimants often compare themselves with another group said to be in a relevantly similar position. If the groups are not truly comparable, the claim may fail; courts sometimes assume comparability and decide the case on justification.
• Status: A personal characteristic or situation falling within “other status” in Article 14 (here, being a mother of NCC child/children).
• Thlimmenos discrimination: Discrimination can occur where the state fails to treat materially different situations differently, without good reason.
• Proportionality (often via Bank Mellat): (i) legitimate aim; (ii) rational connection; (iii) no less intrusive measure; (iv) fair balance between individual rights and community interests.
• “Suspect ground” / “very weighty reasons”: Where differential treatment is on certain grounds (commonly sex), the state must provide especially strong justification.
• Secondary legislation: Regulations made under powers in an Act of Parliament. Courts can quash them if incompatible with Convention rights under the Human Rights Act framework.

6. Conclusion

[2026] EWCA Civ 846 confirms that, for the pre-repeal UC two-child limit regime, it was Convention-compliant to:

• treat adoptive parents and non-parental carers differently from biological parents by fully disregarding such children for ordering purposes, because the exception serves a distinct and powerful aim (avoiding discouragement and avoiding transfer of cost to state care); and
• confine the NCC exception to cases where the third or subsequent child was non-consensually conceived, because the fairness rationale is anchored to lack of choice at the time the cap would bite, and extending the exception to later consensual children would undermine the cap’s policy coherence.

Alongside its substantive Article 14 analysis, the decision is also notable for its appellate approach: guided by Shvidler, the Court of Appeal treated proportionality as a matter it should decide for itself where secondary legislation of general application is challenged on human-rights grounds.
