The development, in size as well as importance, of the international civil service is a relatively recent phenomenon in the international scene. One of its consequences is an increase in die number of problems that may and do arise between an international organization and the members of its staff. Such problems exist in all civil services, national as well as international; they arise in relation to the legal position of the service officials, to their dismissals and promotions (or lack of them), to disciplinary measures against any of them, to their salaries, leaves of absence and other such administrative “details”. On all such questions, the views on which the organization, as represented by its higher administrative officers, bases its actions, may differ from the views of the officials concerned. The facts in each case may be in dispute, or the meaning of the terms and provisions of the contracts of employment and the regulations of the service, may be understood in different ways by die parties concerned.
