Dear Mr. Parveen Kundlu,
As far as I know, there is no such amendment to Section 1, subsection (3) of the Industrial Employment (Standing Orders) Act, 1946. Section 1, Subsection (3) reads as follows: "It applies to every industrial establishment wherein one hundred or more workmen are employed, or were employed on any day of the preceding twelve months." Still, the same is being continued.
Regards, T.M. Rao
