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.
