KV (Sri Lanka) v Secretary of State for the Home Department [2019] UKSC 10

KV, a Sri Lankan Tamil, claimed asylum alleging torture evidenced by burn scars from hot metal rods. The tribunal found his scars were self-inflicted by proxy. The Supreme Court allowed his appeal, holding the tribunal's reasoning flawed and clarifying medical experts' proper role.

Facts

KV, a Sri Lankan national of Tamil ethnicity, arrived in the UK in February 2011 and claimed asylum. He alleged he had assisted the LTTE (Tamil Tigers) by valuing and melting their gold between 2003 and 2008, that he had been arrested and detained by government forces in May 2009, and that during detention in August 2009 he had been tortured by application of hot metal rods to his arm (while conscious) and to his back (while unconscious from the pain). He bore five elongated parallelogram-shaped scars on his back and two scars on his right arm.

Dr Zapata-Bravo, a medical expert trained by the Helen Bamber Foundation, examined KV and, applying the Istanbul Protocol, concluded that his clinical findings were “highly consistent” with KV’s account. He drew a crucial distinction: the scars on the back had precise, parallel edges indicating branding while unconscious, whereas the scars on the arm had blurred, non-parallel edges indicating branding while conscious, which correlated with KV’s account.

The Upper Tribunal rejected KV’s account, finding that only two real possibilities existed: torture as claimed, or wounding Self-Inflicted By Proxy (“SIBP”). It concluded his torture account did not withstand scrutiny and dismissed his appeal. The Court of Appeal majority upheld that decision and made controversial observations that Dr Zapata-Bravo had exceeded the proper limit of his role as a medical expert.

Issues

The appeal raised two principal issues:

• Whether a medical expert preparing a report under the Istanbul Protocol is entitled to offer an opinion on the consistency of clinical findings with the asylum-seeker’s overall account of torture, or only with the immediate mechanism of injury.
• Whether the Upper Tribunal’s reasoning in rejecting KV’s claim contained errors of law, particularly in its treatment of Dr Zapata-Bravo’s key clinical finding and its assessment of the relative likelihood of torture versus wounding SIBP.

Arguments

Appellant and Intervener (HBF)

KV argued that the tribunal’s reasoning was flawed: it mislaid the pivotal distinction Dr Zapata-Bravo drew between the scars on the back and those on the arm, and failed to weigh the inherent improbability of wounding SIBP against the hypothesis of torture. The HBF submitted that experts are entitled, in appropriate cases, to express a view as to belief in the torture account.

Respondent

The Home Secretary, on this appeal, did not seek to defend the Court of Appeal majority’s observations about Dr Zapata-Bravo exceeding his remit. She urged realism in appellate scrutiny of a 368-paragraph determination and pointed to the absence of a transcript below.

Judgment

Lord Wilson (with whom Lady Hale, Lady Black, Lord Briggs and Lord Kitchin agreed) allowed the appeal and directed that KV’s asylum appeal be redetermined by the tribunal.

The role of medical experts

The Court held that the Court of Appeal majority’s observations were erroneous. Medical experts can legitimately offer opinions on the consistency of their findings with the asylum-seeker’s account of the circumstances in which scarring was sustained, not merely the mechanism of injury. The word “trauma” in paragraph 187 of the Istanbul Protocol covers the wider circumstances in which injury is said to have been sustained, as confirmed by paragraphs 105, 122 and 188 of the Protocol. The Practice Direction and the Istanbul Protocol are not inconsistent; when investigating torture, experts should treat the Protocol as equally authoritative.

Where an expert places findings in Istanbul Protocol categories (a) “not consistent” or (e) “diagnostic of”, this is tantamount to disbelief or belief in the account. For categories (b), (c) or (d), there is no room for expression of belief; the credibility conclusion rests with the decision-maker.

Errors in the tribunal’s reasoning

The Court identified two critical errors. First, at paragraph 348 of its determination, the tribunal “mislaid” Dr Zapata-Bravo’s pivotal distinction between the blurred edges of the arm scars (indicating consciousness) and the precise edges of the back scars (indicating unconsciousness). The tribunal’s summary failed to limit the reference to precise edging to the back, and addressed a hypothesis contrary to that advanced by KV and the doctor. Lord Wilson endorsed Elias LJ’s dissent that the tribunal had to find an explanation for the different appearance of the arm scars and could not dismiss KV’s account without doing so.

Secondly, the tribunal failed properly to weigh the extreme improbability of wounding SIBP against the possibility of torture. SIBP required: an extreme decision to self-inflict deep injury; a willing accomplice; anaesthesia administered by a medically qualified person prepared to breach ethics; an explanation for the differential presentation of back and arm scars; and an explanation for the number of wounds, when one or two strategically placed scars would have sufficed for a false claim. Background country evidence established widespread torture by Sri Lankan state forces including burning with soldering irons, while evidence of wounding SIBP was almost non-existent.

Implications

The decision clarifies that medical experts reporting under the Istanbul Protocol may properly address the consistency of clinical findings with the asylum-seeker’s broader account of torture, not merely with the physical mechanism of injury. This reaffirms the authority of the Protocol alongside the Tribunal Practice Direction in cases involving allegations of torture, and aligns with earlier Court of Appeal authority in SA (Somalia).

The judgment also reinforces the principle that, while appellate courts should be cautious in interfering with evidential conclusions in asylum cases, careful scrutiny is warranted given the potentially catastrophic consequences of a mistaken rejection. Where a tribunal rejects expert evidence, it must engage with the expert’s key findings rather than mislay or mischaracterise them.

Importantly, where a tribunal concludes only two real possibilities exist, it must properly weigh the relative likelihood of each before discounting one. The inherent rarity of wounding SIBP – requiring an accomplice, anaesthesia, and medical complicity – must be expressly factored into the analysis.

The decision matters particularly to asylum-seekers alleging torture, to medical experts preparing medico-legal reports, and to tribunals assessing such claims. It does not disturb the principle that credibility assessment remains the decision-maker’s function, nor does it entitle experts routinely to express personal belief in asylum-seekers’ accounts save where their findings fall within Protocol categories (a) or (e).

Verdict: Appeal allowed. The Supreme Court directed the Upper Tribunal to determine afresh KV’s appeal against the refusal of asylum.
