Sure you want reference for everything but if someone asks something then he needs to “google” 
Coming back to your statement
Please re-read the UNSC resolution 98 article 4 … it does not have any reference to UNCIP … so you know what that means.
Sure if you look at the next UN resolution of 1957 … it clearly states what resolutions are to be the principle for resolution … no mention of this resolution 98 of 1952
Reminding the Governments and authorities concerned of the principle embodied in its resolutions 47(1948) of 21 April, 1948, 51(1948) of 3 June, 1948, 80 (1950) of 14 March, 1950 and 91(1951)of 30 March, 1951, and the United Nations Commission for India and Pakistan resolutions of 13 August, 1948, and 5 January, 1949, that the final disposition of the State of Jammu and Kashmir will be made in accordance with the will of the people expressed through the democratic method of a free and impartial plebiscite conducted under the auspices of the United Nations
Once again UN stressing the UNCIP resolutions …
