The Permanent Court of Arbitration (PCA) is an intergovernmental organization headquartered in The Hague, the Netherlands. It is not a tribunal in the traditional sense, but it provides the services of the Court of Arbitration to resolve disputes arising from international agreements between Member States, international organisations or private parties. [3] Cases include a number of legal issues relating to territorial and maritime borders, sovereignty, human rights, international investment and international and regional trade. The APC consists of two separate multilateral conventions[4] and a combined membership[5] of 122 states. [5] The Organization is not a United Nations organization,[6] but the PCA is an official observer of the United Nations. [7] The Permanent Court of Arbitration (APC) has entered into a contract with the Netherlands for its seat. It provides that the CPA is immune from legal proceedings and its property. The CPA also has a number of hospitality agreements that grant privileges and immunities to its employees, warrant officers and participants in PCA-managed procedures. The International Chamber of Commerce (ICC) Court of Arbitration is part of the ICC, a non-governmental economic organization organized according to the laws of France. There are not the same treaties that provide for the defence of diplomatic immunity as the CPA. Many free trade agreements provide for a mechanism for resolving investor-state disputes through arbitration through so-called ISDS clauses.

The CPA can play a role in a proceeding as the authority vested with the power to appoint arbitrators, using its arbitration rules or supporting arbitration. [32] If there are problems with the appointment of arbitrators for arbitration in accordance with THE CNUDCI arbitration rules (for example. B because one of the parties refuses to appoint an arbitrator or if the designated arbitrators cannot agree on the appointment of a third arbitrator), the general secretary of the PCA may be sought as an authority with the power of appointment. This option is also open to other arbitration agreements that appoint the Secretary-General. [27] Between 2011 and 2015, 257 such applications were filed. [1] The secretariat of the APC (international office) by its secretary general provides administrative assistance to the courts and commissions and may also assist in the selection of arbitrators or be appointed as the authority with the power of appointment. Thus, UNCIA`s arbitration rules instruct the ACP Secretary General to appoint, at the request of a party to the arbitration, an “authority with the power of appointment” if the parties have not made such a designation by mutual agreement. While the aforementioned parties wish to reach a broader agreement, the CPA has been pursuing a policy of concluding agreements with its contracting parties on the host country since the 1990s, with a view to making its dispute resolution services more widely available worldwide, and not just at its headquarters at the Peace Palace in The Hague. These agreements allow the host country and the APC to establish a legal framework in which CPA-managed procedures (including arbitration, mediation and mediation and commissions of inquiry) can be implemented within the host country under conditions similar to those provided in the CPA headquarters agreement with the Kingdom of the Netherlands.
