Some summary of the whole Sabah claim and official UN documents that show Sabah, Sarawak and Singapore was officially declared to be part of the Federation of Malaysia.
EXCHANGE OF CORRESPONDENCE
This was the proposal drafted and sent to UN to assimilate Sabah and Sarawak into a single federation called The Federation of Malaysia and how to gauge responses from the occupants of those separate states that says they agree to join the Federation of Malaysia. This also details that Indonesia and Philippines (who then also state that Sabah and Sarawak belongs to them) should be part of the team of observers being there when the mission to gauge if these 2 seperate states(Sabah Sarawak) do indeed want to join Malaysia. It also states the terms and condition of how to gauge the 2 states occupant's intent.
REPORT OF
UNITED NATIONS MISSION
Here it clearly states that during the mission, reps from all 3 claimant countries, Malaysia, Indonesia and Philippines were present during the mission
Here is shows their survey included everybody of value and can be considered decision makers of the occupants of these 2 states.
...and here it shows that the people if Sabah and Sarawak themselves choose to be part of Malaysia.
CONCLUSIONS OF SECRETARY-GENERAL
Here the Sec Gen of UN officially announces that Indonesia and Philippines agree and have no objection to the formation of the Federation of Malaysia with 2 new states, Sabah and Sarawak, chosen via free will by occupants of Sabah and Sarawak
...and it's official!
Malaysia was born! (the first count being that the people who chose to join was not stupid and can think for themselves)
Then in the next meeting, only they say they don't approve
...but the claim was turned down as UN says it is a non-issue.
u can read the official declaration UN's declaration at http://unyearbook.un.org/1963YUN/1963_P1_SEC1_CH3.pdf , page11
then u have the treaty signed between UK n Malaysia saying that UK gives up control of Sabah and Sarawak to Malaysia
And below....u can see that the Ph government have also been advised against continuing claiming that Sabah is theirs as they know that based on the original UN declaration back in 1963, our asses are covered pretty well...
