II. Source of arbitrator's duties
A. Contractual theory
When institutional arbitration is agreed upon, the institutional rules are incorporated in the arbitrator’s contract.4 Most institutional rules prescribe certain procedures to follow as a part of the arbitrator’s duties, such as confidentiality, disclosing conflicts, adhering to timetables and maintaining impartiality and independence.5
B. Legal status theory
This theory states that duties of an arbitrator is quasi-judicial derived from the applicable law and is similar to the position of judges.6 Courts in a number of jurisdictions however have leaned towards the relationship being contractual.7 English courts have held that the relationship is a conjunction of contract and status.8
Several codes of conducts or ethics have been specifically designed for arbitrators.11 While non-enforceable, these recommendary guidelines are nevertheless influential.12 The recently issued draft Code of Conduct for Adjudicators in Investor-State Dispute Settlement released by the Secretariats of ICSID and UNCITRAL marks a continued push towards stronger ethical commitments by arbitrators, however this code is yet in a draft stage.13
III. Different forms of duties
While the different sources prescribe different duties, it is commonly accepted that the most basic duty of arbitrators is to resolve the parties’ dispute.14 This requires maintaining due process, which includes ensuring impartiality and independence, jurisdiction and equality of arms.15 The arbitrators also have a duty to be free of corruption themselves.16
Most sources of arbitrators’ duties impose differing standards of confidentiality.21
Arbitrators’ contractual obligations generally include abiding by the mandate conferred by the parties, including abiding by the parties’ choice of law.22 It also requires maintaining accuracy and party autonomy, with a fidelity to the text and context and an aim to understand the events and how the legal norms apply to the concerned events.23
A number of civil law jurisdictions authorise or obligate arbitrators to reach a settlement agreement between the parties.24 Settlement is relatively less frequent in common law countries.25
IV. Consequences of breach of duties
Arbitrator duties are enforced via a variety of mechanisms depending on the procedural rules that govern the arbitration and severity of the breach, including removal of the arbitrator, loss of remuneration, prohibition from future appointments, and imposition of civil liabilities.26 Arbitrators may also be sued by the parties for breach of contract, however this is subject to the immunities provided to arbitrators in the jurisdiction.27 Serious breaches may also entail setting aside or annulling the award.28
