Basfar v Wong
Factual and Procedural Background
The Appellant, a domestic worker, alleges that the Respondent, a diplomat accredited to the United Kingdom, trafficked her into The State and subjected her to exploitative working conditions in his private residence. Relying on a range of statutory and common-law causes of action, she commenced proceedings in an Employment Tribunal. The Respondent invoked diplomatic immunity under article 31(1)(c) of the Vienna Convention on Diplomatic Relations (“the Diplomatic Convention”). Both the Employment Tribunal and the Employment Appeal Tribunal upheld the Respondent’s plea of immunity. The Appellant appealed to the Supreme Court. The text provided is the dissenting judgment of Judge Hamblen and Judge Rose, who would have dismissed the appeal and preserved the Respondent’s immunity.
Legal Issues Presented
- Whether the Respondent’s alleged trafficking and exploitation of the Appellant constitutes “commercial activity outside his official functions” within the meaning of article 31(1)(c) of the Diplomatic Convention, thereby removing his immunity from civil suit.
- Whether subsequent developments in international law on human trafficking, forced labour and domestic servitude have altered the meaning of “commercial activity” since the Convention was concluded in 1961.
- Whether, at this stage of the litigation, the Appellant should be permitted to rely on alternative claims of forced labour or domestic servitude that were not pleaded below.
Arguments of the Parties
Appellant's Arguments
- The alleged trafficking brings the employment relationship within article 31(1)(c) because it involves the Respondent deriving financial benefit from under-paid labour, amounting to a “commercial activity.”
- International instruments adopted after 1961—especially the Palermo Protocol—show a global consensus against trafficking that should inform a modern, ambulatory reading of “commercial activity.”
- Permitting immunity in these circumstances would undermine contemporary human-rights norms and the object and purpose of the Diplomatic Convention.
Respondent's Arguments
- Domestic employment, even if exploitative, is incidental to daily household life and is not a “commercial activity.”
- No subsequent treaty or state practice evidences a consensual change in the meaning of article 31(1)(c); immunity therefore remains intact.
- Expanding the exception would create uncertainty, invite intrusive inquiries into diplomats’ private lives and expose the United Kingdom’s diplomats abroad to retaliatory measures.
Table of Precedents Cited
| Precedent | Rule or Principle Cited For | Application by the Court |
|---|---|---|
| Reyes v Al-Malki [2017] UKSC 61 | Interpretation of “commercial activity” under article 31(1)(c); immunity for domestic employment | Dissent relies on Judge Sumption’s analysis that ordinary domestic employment is not commercial and that trafficking does not alter that classification. |
| Tabion v Mufti 73 F.3d 535 (4th Cir. 1996) | Domestic service contracts are not “commercial activity” for diplomatic-immunity purposes | Cited as persuasive evidence of consistent state practice rejecting the commercial-activity characterization. |
| Sabbithi v Al Saleh 605 F.Supp.2d 122 (D.D.C. 2009) | Trafficking and labour statutes do not override diplomatic immunity | Reinforces the view that even egregious exploitation does not defeat immunity. |
| Montuya v Chedid 779 F.Supp.2d 60 (D.D.C. 2011) | Follows Tabion and Sabbithi on scope of “commercial activity” | Used to demonstrate continuing uniform U.S. jurisprudence. |
| Fun v Pulgar 993 F.Supp.2d 470 (S.D.N.Y. 2014) | Trafficked domestic work falls outside article 31(1)(c) | Cited as further evidence of foreign-court practice. |
| Costa Rica v Nicaragua (2009) ICJ Rep 213 | Treaty terms may have an ambulatory meaning when drafted in generic language | Dissent distinguishes this principle, concluding that the phrase “commercial activity” was intended to be fixed, save for new types of business unknown in 1961. |
| Barnet LBC v Attorney General [2021] EWHC 1253 (Fam) | Later human-rights instruments do not override diplomatic immunity | Invoked to analogise the failed attempt to create new article 31 exceptions based on child-protection norms. |
| Jones v Ministry of the Interior of Saudi Arabia [2006] UKHL 26 | Prohibition of torture (a jus cogens norm) does not automatically trump state immunity | Applied by analogy: trafficking norms likewise do not override diplomatic immunity absent clear state practice. |
| Hounga v Allen [2014] 1 WLR 2889 | Public-policy considerations regarding trafficking in domestic-law illegality defences | Illustrates the factual complexity of determining trafficking but does not alter the interpretation of article 31(1)(c). |
| Ajayi v Abu [2017] EWHC 3098 (QB) | Judicial methodology for deciding trafficking claims | Dissent cites the case to show how intrusive factual inquiries would become under the majority’s approach. |
Court's Reasoning and Analysis
Judge Hamblen and Judge Rose agree with the majority on several interpretive principles but diverge sharply on the outcome:
- Ordinary meaning & context: “Commercial activity” refers to business-like operations undertaken for profit; purchasing household services for personal use is consumer behaviour, not commerce.
- Historical intent: The Diplomatic Convention’s travaux préparatoires show that delegates contemplated domestic servants but deliberately chose not to include their employment within the commercial-activity exception.
- Absence of evolutionary change: While treaties can evolve, no post-1961 treaty, state practice or scholarly consensus supports expanding “commercial activity” to include trafficking, forced labour or servitude when these are unconnected to a broader business enterprise.
- Risk to diplomatic reciprocity: Broadening the exception invites retaliatory measures against United Kingdom diplomats and undermines the stability of diplomatic relations.
- Practical concerns: Determining whether trafficking occurred demands intrusive, fact-intensive inquiries into diplomats’ private lives, contrary to the spirit of immunity.
- Pleading limitations: The Appellant cannot pivot to alternative theories of forced labour or servitude at this stage because those claims were neither pleaded nor tested below.
Holding and Implications
HOLDING: The dissent would have DISMISSED THE APPEAL, upholding the Respondent’s immunity.
Implications: Had their view prevailed, employment claims—even those involving trafficking—against serving diplomats would remain non-justiciable unless connected to a distinct profit-making enterprise. The dissent emphasises preserving the existing balance of diplomatic privileges and warns that unilateral judicial expansion could jeopardise British diplomatic personnel abroad. No new precedent would have been set.
