Arbitrator independence and impartiality is central to arbitration. In the current geopolitical turbulence, the question arises whether independence and impartiality also require neutrality in a broader sense. For example, can an US arbitrator be considered independent and impartial in a dispute involving an Iranian party or a Russian arbitrator be considered independent and impartial in relation to a Ukrainian party? What is the currently prevailing view and are there reasons to adapt it? Is the test different for party-appointed arbitrators and chairpersons? What is the role and responsibilities of arbitral institutions?
