DA & Ors, R (on the application of) v Secretary of State for Work and Pensions

Factual and Procedural Background

The appeals concerned two linked sets of claimants (“Appellants”) who challenged the revised statutory limit on total welfare entitlement (“the revised benefit cap”) introduced by the Welfare Reform and Work Act 2016 and associated regulations. The cap, set at £23,000 per year in Greater London and £20,000 elsewhere, operates by reducing Housing Benefit or Universal Credit once a household’s overall welfare income would otherwise exceed those figures.

Both appellant groups comprise lone-parent families whose total benefits were reduced. One appeal (“DA”) focuses on lone parents with at least one child under two; the second (“DS”) focuses on lone parents with at least one child under five. Each contends that treating them the same as all other capped households is discriminatory and violates Article 1 of Protocol 1 and Article 8 of the European Convention on Human Rights (“ECHR”), read with Article 14.

At first instance Judge Collins held in favour of the DA claimants, declaring the regulations discriminatory. The Court of Appeal (majority) reversed that decision. For DS, Judge Lang dismissed the claim but granted a leap-frog certificate so that both cases were heard together by the Supreme Court (“the Court”).

Legal Issues Presented

1. Whether the revised benefit cap falls within the ambit of Article 8 ECHR so that Article 14 is engaged.
2. Whether the Appellants possess a relevant “status” under Article 14 (namely: lone parents, lone parents with children under five / under two, and those children themselves).
3. Whether applying the same cap to the Appellants as to other households amounts to discrimination of the Thlimmenos type (similar treatment of relevantly different groups).
4. What test of justification applies to economic measures: “manifestly without reasonable foundation” or the ordinary proportionality/fair-balance test.
5. Whether the Secretary of State’s refusal to exempt the Appellants breaches Article 3(1) of the UN Convention on the Rights of the Child (“UNCRC”) and, if so, its relevance to Article 14.
6. Ultimately, whether the impugned regulations are compatible with the Appellants’ Convention rights.

Arguments of the Parties

Appellants' Arguments

• The cap disproportionately affects lone-parent families with very young children, a group whose childcare responsibilities make paid work harder; equal treatment with other capped households therefore breaches Article 14.
• The entitlement to benefits is property (A1P1) and a mode of family life support (Article 8); thus Article 14 is engaged.
• Lone parents (and their children) constitute a “status”; treating them identically to dual-parent households or lone parents of older children is unjustified.
• The correct test is a full proportionality analysis; the “manifestly without reasonable foundation” (“MWRF”) standard is inappropriate at national level.
• The Government failed to treat children’s best interests as “a primary consideration” under Article 3 UNCRC; that failure colours the proportionality assessment.
• Reliance on Discretionary Housing Payments (“DHPs”) is inadequate because awards are short-term, uneven and cover only housing shortfalls, not wider poverty effects.

Defendant's Arguments

• The benefit cap pursues legitimate aims: (i) fairness between working and non-working households; (ii) fiscal savings; (iii) incentivising employment.
• The disproportionate impact on lone-parent women reflects labour-market realities, not unlawful discrimination; previous case-law (SG) rejected a similar sex-discrimination claim.
• DHPs provide a safety-valve for hardship; five of six appellant mothers have received them.
• Under settled authority (Humphreys; MA) a welfare rule is compatible unless shown to be “manifestly without reasonable foundation,” a threshold not met here.
• UNCRC is not binding domestic law; in any event the Government considered children’s interests and Parliament endorsed the policy after full debate.

Court's Reasoning and Analysis

All Justices accepted that entitlement to welfare benefits lies within Article 8 and Article 1 Protocol 1, triggering Article 14. They also accepted that lone-parent status (and sub-groups based on a child’s age) is capable of amounting to “other status.” The key dispute lay in justification and the correct intensity of review.

Majority (Judge Wilson, Judge Hodge, Judge Carnwath, Judge Hughes)
The majority treated the measure as part of economic policy and applied the “manifestly without reasonable foundation” test. They found:

• The aims of fairness, fiscal savings and work-incentivisation are legitimate.
• Statistics show lone parents are heavily affected, but Parliament chose not to draw further exemptions after considering evidence and the availability of DHPs.
• UNCRC considerations were taken into account at a “primary” level; even if children’s interests were adversely affected, the policy choice was not manifestly unreasonable.
• DHPs, though imperfect, provide a bespoke mitigation mechanism and five of six appellant households had received them.

Dissent (Judge Hale, Judge Kerr)
The dissenting Justices rejected MWRF for the final proportionality balance, favouring the ordinary four-stage domestic test. They concluded:

• Evidence shows negligible fiscal benefit and little realistic work incentive for parents of very young children.
• The cap drives already vulnerable families below poverty lines and risks long-term harm to children; DHPs are inadequate to offset this.
• Government failed to give children’s best interests primary weight as required by Article 3 UNCRC; consequently the measure was disproportionate.
• A declaration of incompatibility should have been made.

Holding and Implications

DISMISSED: By a majority, the Court upheld the legality of the revised benefit cap as applied to lone-parent families with children under five, finding that the failure to exempt them was not manifestly without reasonable foundation and therefore not discriminatory under Article 14.

Implications: The judgment re-affirms the high level of deference national courts will show to Parliament in social-security design when the MWRF standard is applied. No immediate change to the regulations is required, but two powerful dissents highlight continuing concerns about child-poverty effects and leave open the possibility of future legislative or judicial review.
