You do know that holding plebicite by India is under a non-binding resolution Chap VI art 35 of UN
As for the binding nature of the UN Resolutions and India's chapter VI mantra:
The UNSC Resolutions on Kashmir are neither "Unenforceable" nor "Non-binding" ...
1) UN maintains that "NO SECURITY COUNCIL RESOLUTION CAN BE DESCRIBED AS UNENFORCEABLE."
2) There always has been a general inability of the Permanent Five to agree upon imaginative and expansive applications of Chapter VI ... In Somalia, the Security Council deployed the UN's first operation, UNOSOM I, in mid-1992 to separate warring combatants and help delivery of humanitarian relief ....
UNOSOM I entered and operated without invoking Chapter VII

3) India approached UN under Chapter VI of the UN charter , BUT the decision taken by UN reflected that its resolutions were not based exclusively on this chapter .... The resolutions , apart from chapter VI , are based upon other chapters , including chapter VII
The fact that there does not exist any provision for the deputing of UN peace keeping mission under chapter VI makes it obvious that UN resolutions were not exclusively based on chapter VI .... The interim measures which included cease fire and deputation of United Nations Military Observer Group were based on Article 40 of chapter VII ...
Besides chapter VI and VII , UN resolutions are based on other chapters also(i.e Article 1 , Chapter I (2) and Article 55 , Chapter IX) ...
^^ And this is not my personal opinion. That is Rosalyn Higgins' opinion on 'Kashmir Resolutions and under which chapter they were passed' .. Source: 'Higgins, Rosalyn. United Nations Peace Keeping 1946-67: Documents and Commentary. London, UK: Oxford University Press, 1970. (349-51)
(Rosalyn Higgins is an expert on International Law; a Doctor of Juridical Science. She has served as a Judge in the International Court of Justice for fourteen years (and was elected President in 2006). Her competence has been recognised by many academic institutions, having received at least thirteen honorary doctorates)
4) While a recommendation under Chapter VI by itself "may not" be binding, this is not the case in the Kashmir dispute. Here, the parties have consented to be bound by the resolutions of 13 August and 5 January.
(13 M. WHITEMAN, DIGEST OF INTERNATIONAL LAW 360 (1968).
5) The UNSC Resolutions endorsed a binding agreement between India and Pakistan reached through the mediation of UNCIP, that a plebiscite would be held, under agreed and specified conditions. A letter dated December 23, 1948, from India's Secretary-General of the Ministry of External Affairs to the Representative of UNCIP, stated that the Indian Prime Minister's acceptance of the 5 January resolution was conditioned on Pakistan's acceptance of the resolution. By this letter, India consented to be bound by the resolution of 5 January and, through this, the resolution of 13 August as well.
(Aide Memoire No. 1, Letter Dated 23 December 1948 From the Secretary General of the Ministry of External Affairs and Commonwealth Relations of the Government of India to Mr. Alfredo Lozano, Representative of UNCIP at 23, U.N. Doc. S/1196 (1949)
6) Self-Determination as a Binding Rule of International Law
Four instances may inform the principle of self-determination with a legal dimension.
(i)
The principle of self-determination is binding upon the parties, whether they have adopted it as the basis or as a criterion for the settlement of a particular issue or dispute. In the peace treaties after World War I, and in the cases of Kashmir (after 1948), the Saar Territory (1955), and Algeria’s struggle for independence, the principle of self-determination was chosen as a basis for negotiation, and in the Agreement on Ending War and Restoring Peace in Vietnam (1973) the parties expressly recognized the South Vietnamese people’s right to self-determination.

7) The binding nature of these UN resolutions (as acknowledged by Indian officials)
Finally some quotes from Indian officials on Kashmir exemplifying their commitment to plebiscite rather than forced accession as history has found them do :-
We adhere strictly to our pledge of plebiscite in Kashmir; a pledge made to the people because they believe in democratic government; We don't regard Kashmir as a commodity to be trafficked in -Krishna Menon (Press statement in London, reported in the Statesman, New Delhi, 2nd August, 1951)
The Government of India not only reaffirms its acceptance of the principle that the question of the continuing accession of the State of Jammu and Kashmir to India shall be decided through the democratic method of a free and impartial plebiscite under the auspices of the United Nations, but is anxious that the conditions necessary for such a plebiscite should be created as quickly as possible -Letter from Govt. of India to UN Representative for India and Pakistan, 11th September, 1951
I want to say for the purpose of the record that there is nothing that has been said on behalf of the Government of India which in the slightest degree indicates that the Government of India or the Union of India will dishonour any international obligations it has undertaken.
-Krishna Menon (Statement at UN Security Council, 24th January, 1957)
The resolutions of January 17, 1948 and the resolutions of the UNICP, the assurances given, these are all resolutions which carry a greater weight; that is because we have accepted them, we are parties to them, whether we like them or not. -Krishna Menon, (Statement at UN Security Council, 20th February, 1957)
These documents (UNCIP reports) and declarations and the resolutions of the Security Council are decisions; they are resolutions, there has been some resolving of a question of one character or another, there has been a meeting of minds on this question where we have committed ourselves to it. -Krishna Menon, (Statement at the Security Council, 9th October, 1957)
India believes that sovereignty rests in the people and should return to them. -Krishna Menon, (The Statesman, Delhi, 19th January, 1962)
Therefore, India is bound by word and deed to leave the future of Kashmir to the will of its people.
