For example, section 2 of the act defined the territories of India and Pakistan This clause, post-independence, had no legal effect, since the borders of the territories became a matter for the two new Dominions, and not the British.  [Repeal acts, like that of 1976,][1] "tidy up" lots of laws like this that have become irrelevant, such as the large amounts of legislation that referred to "British India" that still existed.
