As per The Contract Labour (Regulation & Abolition) Central Rules, 1971:
The Act is applicable to every establishment in which twenty or more workmen are employed or were employed on any day of the preceding twelve months as contract labour.
Definition of Establishment
Section 2(e) of the Act also says that:
“Establishment” means any office or department of the government or a local authority or any place where any industry, trade, business, manufacture, or occupation is carried on.
Supreme Court Judgment on Construction
However, concerning Construction, there is a judgment of the Hon'ble Supreme Court of India in the matter "Gammon India Ltd. v. Union of India, (1974) 1 SCC 596: 1971 SCC (L & S) 252" in which it is clearly mentioned that:
“In connection with the expansion of establishment, buildings are constructed. The site chosen for the building is the work site of the establishment. The work site is the place where on completion of construction, the business of the establishment will be carried on. Therefore, the work at the site as understood in the definition is the work of an establishment. Establishment is understood as including the work site.”
So, in view of the above, if the construction work is not related to any Business Organization for the purpose of Business purpose, it will not fall under the scope of the Act.
I would like to request the learned member to kindly provide your views on this.
