Hounga v Allen & Anor

Factual and Procedural Background

The Appellant, a national of Country A and aged approximately 14 at the material time, was brought to Country B in January 2007 under arrangements orchestrated by the Respondent and her family. Entry was secured through the use of a false identity and the grant of a six-month visitor visa. Although she had no right either to work or to remain after July 2007, the Appellant lived in the Respondent’s household for 18 months, caring for the Respondent’s children without pay and without the promised schooling.

On 17 July 2008 the Respondent forcibly evicted the Appellant following a violent incident. The Appellant subsequently lodged multiple claims before the Employment Tribunal, including contractual claims (unfair dismissal, unpaid wages) and statutory complaints under the Race Relations Act 1976. The Tribunal:

• Found a contract of employment existed but struck out all contract-based claims on the ground of illegality.
• Dismissed a harassment complaint for procedural reasons.
• Upheld the complaint of race discrimination in respect of dismissal and awarded £6,187 for injury to feelings.

The Employment Appeal Tribunal upheld the discrimination award. The Court of Appeal, however, allowed the Respondent’s cross-appeal, holding that the defence of illegality barred the discrimination claim. The Appellant appealed to the Supreme Court (“the Court”).

Legal Issues Presented

1. Whether, and in what circumstances, the defence of illegality defeats an employee’s statutory claim for racial discrimination arising from dismissal contrary to section 4(2)(c) of the Race Relations Act 1976 (now section 39(2)(c) of the Equality Act 2010).
2. Whether the Appellant’s unlawful immigration status and participation in an illegal employment contract were so “inextricably linked” to the discrimination claim that allowing the claim would offend public policy.

Arguments of the Parties

Appellant's Arguments

• The discrimination tort is distinct from the illegal contract; the dismissal and accompanying abuse constitute a separate wrong.
• Public-policy considerations, including international obligations to protect victims of trafficking and forced labour, favour permitting the claim.
• The Respondent’s threats leveraging the Appellant’s immigration status demonstrate exploitation rather than a basis for denying relief.

Respondent's Arguments

• The Appellant knowingly entered an illegal employment arrangement; her claim is therefore barred under the doctrine of ex turpi causa.
• The discrimination was “obviously” inseparable from the illegality because it relied on the Appellant’s vulnerability as an unlawful migrant worker.
• (Procedurally rejected) Additional submissions based on the private-household exemption in section 4(3) of the 1976 Act and on the correct statutory comparator.

Court's Reasoning and Analysis

Judge Wilson (with Judges Hughes and Carnwath concurring) analysed the defence of illegality as a doctrine rooted in public policy. The Court:

1. Reviewed historical approaches (“reliance” and “inextricable link” tests) and noted their inherent subjectivity and potential arbitrariness.
2. Emphasised that the underlying purpose of the doctrine is to maintain the integrity of the legal system, per the persuasive Canadian authority Hall v Hebert.
3. Applied four policy questions:
   1. Would the award let the Appellant profit from wrongdoing? – No.
   2. Would it evade a criminal penalty? – No.
   3. Would it encourage others to enter illegal employment? – No.
   4. Would denying relief encourage employers to exploit undocumented workers? – Potentially yes.
4. Considered international obligations (Palermo Protocol, Council of Europe Convention, Article 4 ECHR) which require effective protection and compensation for trafficking victims or those in analogous forced-labour situations.
5. Concluded that although the Appellant’s immigration offences formed the backdrop, they were no more than contextual; the discriminatory dismissal was a distinct statutory tort.
6. Held that applying the illegality defence would conflict with prevailing public-policy objectives against exploitation and trafficking.
7. Judge Hughes added that the decisive factor was the insufficiently close connection between the immigration offences and the discrimination tort; the offences merely provided the setting, not the basis, of the claim.

Holding and Implications

APPEAL ALLOWED. The discrimination award made by the Employment Tribunal is restored. The harassment complaint is remitted to the Tribunal for further consideration consistent with the Supreme Court’s judgment.

Implications: The decision clarifies that, in statutory discrimination claims, the defence of illegality will not succeed unless the unlawful conduct is sufficiently connected to the alleged discrimination. It underscores the courts’ readiness to weigh broader public-policy considerations—particularly the protection of vulnerable or trafficked workers—over a mechanical application of the illegality doctrine. No new categorical test was created, but the judgment signals a more nuanced, policy-driven approach in future cases.
