Congratulation, now you are taking what I said, lot earlier. Agreement is only valid until both parties consider it valid, it is not binding by any international order. ICJ rejection had other commonwealth related factors not simla agreement
UN too is an agreement. Until one country says it is withdrawing officially from mutual agreement, it is binding over UN. International orders themselves aren't binding. In international scenario, it is might is right.
And here is right from ICJ judgement (I highlighted for easy reading)-
"The Court further regards
Article 1 of the Simla Accord, paragraph (ii) of which provides,
inter alia, that "the two countries are resolved to settle their differences by peaceful means through bilateral negotiations or by any other peaceful means mutually agreed upon
between them . . ."
as an obligation, generally, on the two States to settle their differences by peaceful means,
to be mutually agreed by them. The said provision in no way modifies the specific rules governing recourse to any such means, including judicial settlement. The Court cannot therefore accept Pakistan's argument in the present case based on estoppel.
Obligation to settle disputes by peaceful means (paras. 51-55)
Finally, the Court recalls that its lack of jurisdiction does not relieve States of their obligation to settle their disputes by peaceful means. The choice of those means admittedly rests with the parties under Article 33 of the United Nations Charter. They are nonetheless under an obligation to seek such a settlement, and to do so in good faith in accordance with Article 2, paragraph 2, of the Charter.
As regards India and Pakistan, that obligation was restated more particularly in the Simla Accord of 2 July 1972. Moreover, the Lahore Declaration of 21 February 1999 reiterated "the determination of both countries to implementing the Simla Agreement". Accordingly, the Court reminds the Parties of their obligation to settle their disputes by peaceful means, and in particular the dispute arising out of the aerial incident of 10 August 1999, in conformity with the obligations which they have undertaken."

So, no, you can't run to UN if India doesn't agree to it, until simla agreement is in force.
Not very many Indians speak in the US. Only a few Sikhs here talk openly because they not cowards, but we banged them out bad.
