Definition

In plain language

An arbitration award is the decision made by arbitrators chosen to settle a dispute. When the parties have agreed it is binding, they must follow it.

Academic definition

In inter-State arbitration the parties undertake in advance to submit in good faith to the award (Article 37 of the 1907 Hague Convention for the Pacific Settlement of International Disputes), and the award has res judicata effect. Under UNCLOS Annex VII and Article 296, decisions of the tribunal are final and binding, as with the 2016 South China Sea award in Philippines v. China administered by the Permanent Court of Arbitration. In investment arbitration, ICSID awards bind the parties under Article 53 of the Washington Convention, while enforcement depends on domestic courts and State compliance.

Context

Legal effect: Binding

Scope

Covers binding awards in State-to-State and investor-State arbitration; non-binding conciliation reports and advisory opinions are excluded.

Legal context

Hague Convention 1907 Article 37 and Article 81; UNCLOS Article 296 and Annex VII Article 11; ICSID Convention Article 53. Grounds for challenge are limited, such as excess of jurisdiction.

Diplomatic context

States comply with awards through settlement agreements or implementation, but non-appearing States, as China in the South China Sea case, dispute jurisdiction and refuse to accept the award.

Institutional context

Awards are issued by ad hoc tribunals often administered by the Permanent Court of Arbitration, ICSID or arbitral institutions.

Historical context

The 1872 Alabama Claims award between the United States and Britain is a landmark, and the Hague conventions of 1899 and 1907 institutionalised arbitration.

Why it matters

A binding award fixes rights and obligations without appeal, but the lack of an enforcement body means compliance relies on good faith and diplomacy.

Usage

Register: Legal

Usage note

'Award' refers to the final decision; interim decisions are called orders or procedural rulings.

Example

The tribunal issued a binding arbitration award fixing the maritime boundary between the two States.

Example scenario

Two States agree to arbitrate a boundary dispute. The tribunal issues a final award, neither State can appeal it, and both then implement it by demarcating the line on the ground.

Common misuse

Assuming a binding award can be enforced like a court judgment against a State by force; enforcement depends on State compliance.

Not to be confused with

  • ICJ judgment
  • Advisory opinion
  • Conciliation report
