The document discusses the definition of "industry" under the Industrial Disputes Act, 1947 in India through various court cases. It explains that initially the definition was interpreted broadly, but later some institutions like universities and clubs were excluded. The landmark Bangalore Water Supply case in 1978 established the "triple test" for determining if an activity qualifies as an industry, considering its systematic nature, employer-employee cooperation, and production of goods/services. Later, the amended definition of 1982 provided more clarity through exclusions.
