The PCA administers arbitration, conciliation and fact finding in disputes involving various combinations of states, private parties, state entities, and intergovernmental organizations. International commercial arbitration can also be conducted under PCA auspices. The PCA’s two working languages are English and French. However, proceedings may be conducted in any language agreed on by the parties.
The PCA offers hearing facilities at the Peace Palace and ancillary administrative services to tribunals operating ad-hoc or under the auspices of another institution.
Under the UNCITRAL Arbitration Rules, the PCA Secretary-General is charged with designating “appointing authorities” upon the request of a party to arbitral proceedings. The Secretary-General may designate an appointing authority for the appointment of an arbitrator to complete an incomplete arbitral tribunal and/or to decide challenges to arbitrators.
As a centre for scholarship and publication the PCA compiles and edits scholarly works on current issues of international law and dispute resolution.
The PCA houses the Editorial Staff of the International Council for Commercial Arbitration (ICCA) in its premises at the Peace Palace. ICCA’s publications include the Yearbook Commercial Arbitration, the International Handbook on Commercial Arbitration and the ICCA Congress Series.
