As on 15 May 1948 Palestine; which was a legal entity administered under United Nations Mandate by His Britannic Majesty but was not a sovereign state (it was not self-governing) yet the authority responsible for administration of Palestine on the termination of the British Mandate must perforce change.
Also since the Mandatory Power intended to withdraw from Palestine without assuming any responsibility for the establishment of a new regime which would not command general consent in Palestine there would be no regularly constituted authority in the evacuated areas unless the United Nations recommended a way in which the gap could be effectively filled.
The United Nations Commission was also to be the authority for Palestine’s internal administration and for its foreign affairs.
It is the policy of the United Nations Palestine commission as the successor authority to maintain services on the same terms and with the same rights for employees as those enjoyed under the Mandatory Government.
