Single Joint Experts (SJEs) are instructed jointly by both parties to provide independent expert evidence on a specific issue. SJEs are less common in asylum proceedings than in commercial courts but tribunals may direct joint instruction on narrow issues such as linguistic analysis or specific country conditions.
Experts instructed as SJEs must maintain independence and document instructions received from both parties. The expert owes a paramount duty to the tribunal under Ikarian Reefer principles — not to either instructing party.
Fee sharing is typically directed by the tribunal or agreed between parties. LAA prior authority is required for legally aided cases before the expert begins work. Scope, questions, and materials must be agreed before instruction.
SJE directions require careful case management. Solicitors should agree the letter of instruction, documents to be provided, and timetable with the opposing party before approaching the expert. See CPR Part 35 principles applied by analogy in tribunal proceedings.
