Passage: With the British and Muslims to some extent co-operating, the Viceroy asked Jinnah for an expression of the Muslim League's position on self-government, confident that it would differ greatly from that of the Congress. To come up with such a position, the League's Working Committee met for four days in February 1940 to set out terms of reference to a constitutional sub-committee. The Working Committee asked that the sub-committee return with a proposal that would result in "independent dominions in direct relationship with Great Britain" where Muslims were dominant.  On 6 February, Jinnah informed the Viceroy that the Muslim League would be demanding partition instead of the federation contemplated in the 1935 Act. The Lahore Resolution (sometimes called the "Pakistan Resolution", although it does not contain that name), based on the sub-committee's work, embraced the Two-Nation Theory and called for a union of the Muslim-majority provinces in the northwest of British India, with complete autonomy. Similar rights were to be granted to the Muslim-majority areas in the east, and unspecified protections given to Muslim minorities in other provinces. The resolution was passed by the League session in Lahore on 23 March 1940.
