And what possible ramifications were there in the process?
Well, there was U.N. General Assembly Resolution 186: Appointment and terms of reference of a United Nations Mediator in Palestine; May 14, 1948
The General Assembly
Taking account of the present situation in regard to Palestine,
Strongly affirms its support of the efforts of the Security Council to secure a truce in Palestine and calls upon all Governments, organizations and persons to co-operate in making effective such a truce;
...1. Empowers a United Nations Mediator in Palestine, to be chosen by a committee...to: (i) Arrange for the operation of common services necessary to the safety and well-being of the population of Palestine; (ii) Assure the protection of the Holy Places, religious buildings and sites in Palestine; (iii) Promote a peaceful adjustment of the future situation of Palestine;
...Relieves the Palestine Commission from the further exercise of responsibilities under resolution 181 (II) of 29 November 1947.
The Arabs of the former territories of the Mandate of Palestine mst certainly did not do what was asked in that decision.
This was followed by the establishment of a Palestine Conciliation Commission [PCC] in December 1948 but as this article suggests, even before the PCC
Following Israel's emergence, some U.S. officials were openly prepared to jettison the Partition Resolution as obsolete. Philip Jessup, a member of the Policy Planning Staff and the deputy U.S. representative on the Security Council in the summer of 1948, was one of them. He was not the only one who believed that the Resolution was no longer applicable; that its proposal for a Palestinian state and an economic union with Israel was unlikely; and that Israel and the United States would be better served by promoting an increased role for Transjordan's King Abdullah in Palestine.
So, the position that the partition was a dead letter less than a year after it was proposed and cannot be now entered into the diplomatic discourse as, for example, that Jerusalem's fate is till undetermined since the last effective act was its declaration as an international regime, as the US maintains, is contradicted by its own diplomats at that time.
