Dear Mr. Agrawal,
I would be highly obliged if you could provide the list of industries/establishments engaged in any one or more of the industries specified in Schedule I of the Industrial Disputes Act, 1947, or any activity notified by the Central Government in the Official Gazette as "Controlled Industries" for the purpose of Section 2(a)(i) of the Industrial Disputes Act, 1947. If you have a copy of the Gazette, it will suffice for the purpose.
A line in reply is appreciated.
