X has 35 years of experience as counsel, solicitor and mediator in commercial disputes, including LCIA proceedings. X's evidence is that during discussions with the LCIA in March 2018, X made clear that they had not been previously appointed as an arbitrator. X was invited by the LCIA to submit a CV, given X's experience as a mediator and the recognition in the industry that there is no strict delineation between the disciplines. It is common ground that the LCIA was fully aware that X had not previously been appointed as arbitrator in an LCIA arbitration. X says they accepted the appointment in view of their considerable expertise as a mediator and familiarity with the specialist subject matter of the claim.
