Arbitration
The PCA provides administrative support in international arbitrations involving various combinations of states, state entities, international organizations and private parties.
The PCA has experience in administering international arbitrations concerning disputes arising out of treaties, including bilateral investment treaties and multilateral treaties, and other instruments. The PCA also plays an important role under the UNCITRAL Rules. Model arbitration clauses for use in connection with the PCA’s Rules of Procedure and the UNCITRAL Arbitration Rules can be downloaded from the Model Clauses and Submission Agreements link below.
Case Administration
The PCA regularly provides administrative services in support of parties and arbitrators conducting arbitral proceedings under the PCA’s auspices, serving as the official channel of communications and ensuring safe custody of documents. The PCA can also provide such services as financial administration, logistical and technical support for meetings and hearings, travel arrangements, and general secretarial and linguistic support. In addition, a staff member of the International Bureau may be appointed as registrar or administrative secretary for a case and carry out administrative tasks at the direction of the arbitral tribunal.
