What is an Immigration & Asylum Expert Witness?
An immigration and asylum expert witness is a specialist — typically a clinical psychologist, consultant psychiatrist, forensic physician, or country of origin expert — who provides independent, objective evidence to immigration tribunals, the Home Office, and appellate courts on matters within their professional expertise.
Expert evidence in immigration proceedings serves a distinct purpose from advocacy. The expert's duty is to the tribunal, not to the instructing solicitor or the claimant. That duty requires the expert to provide an honest, objective assessment of the clinical or factual issues — including findings that may not support the claimant's case — and to comply with the requirements of the Practice Directions of the First-tier Tribunal (Immigration and Asylum Chamber).
The most frequently instructed expert reports in immigration proceedings are PTSD and trauma assessments, Istanbul Protocol evaluations, psychiatric vulnerability reports, and country of origin information reports. Each addresses a specific question that the tribunal cannot resolve without specialist expertise.

Istanbul Protocol Assessments
UN-standard medico-legal documentation of torture and ill-treatment
The Istanbul Protocol — formally the UN Manual on the Effective Investigation and Documentation of Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment — sets the international standard for the medico-legal documentation of torture. An Istanbul Protocol assessment is accepted by the First-tier Tribunal (Immigration and Asylum Chamber), the Upper Tribunal, and the European Court of Human Rights as authoritative evidence of torture and ill-treatment.
Clinical Interview
A structured clinical interview documents the claimant's account of alleged torture or ill-treatment, including the circumstances, methods used, and the physical and psychological sequelae. The interview follows the Istanbul Protocol framework and is conducted through a qualified interpreter where required.
Physical Examination
A forensic medical examination documents physical evidence of ill-treatment — scarring, injury patterns, and physical sequelae. Each finding is assessed for consistency with the reported mechanism of injury using the Istanbul Protocol's five-point consistency scale: not consistent, consistent, highly consistent, typical, and diagnostic.
Psychological Assessment
Standardised psychological assessment tools (CAPS-5, IES-R, PCL-5, HTQ) are administered to document the psychological sequelae of torture and ill-treatment. The assessment addresses the diagnosis of PTSD, complex PTSD, depression, and anxiety disorders, and their consistency with the reported traumatic history.
Expert Report
The completed Istanbul Protocol report presents the clinical findings, the expert's opinion on the consistency of physical and psychological evidence with the reported ill-treatment, and the expert's overall assessment. The report is prepared for submission to the First-tier Tribunal or Upper Tribunal and is signed by a named, qualified expert.
Country of Origin Information (COI) Evidence
Country of origin information experts provide independent, objective evidence about conditions in a claimant's country of origin. COI reports are particularly valuable where the Home Office Country Policy and Information Notes (CPINs) do not address the claimant's specific circumstances — for example, the treatment of a particular ethnic minority, religious group, or political affiliation in a specific region.
