The basis for demand is exhibit R3. Exhibit R2 is the form C-10. The basis for preparation of the statutory form is ledger book of the 1st respondent establishment. Exhibits R2 and R3 are the observations slips of RW1, the Inspector. The case of the appellant is that the total expenses incurred by the 1st respondent establishment during the period from 01.04.1994 to 31.03.1997 is more than Rs.25,00,000/-. According to the evidence of RW1, from 01.04.1994 to 31.03.1997, towards labour charges paid to construction coolies, building repairs and maintenance, security guard charges, difference in wages, salaries and MBs remuneration, an amount of Rs.13,94,240/- was incurred. The amounts referred to by the appellant would show the cost of building materials, cost of repairs of machinery etcetera. The evidence brought on record would show that the 1st respondent establishment gave the work of maintenance of plant and machinery to a contractor and also the construction work to a contractor and, therefore, as rightly contended the contractors might have paid contributions to the Corporation for the workers engaged by them for maintenance of machinery and construction work respectively. The Officers of the Corporation did not make any enquiries and they did not produce any evidence to show that the contractors did not pay any contributions. Further construction workers will be engaged through a maistry. There will be change of coolies from day to day. The same coolies may not work everyday for construction purpose. Though cold storage is a manufacturing process, the construction of buildings and repairs intended for use of the 1st respondent establishment, as rightly contended, do not fall within the ambit and sweep of manufacturing process. Even assuming that construction work in the instant case is a manufacturing process, unless it is established that it is a case of immediate employer or ultimate employer – employee relationship, the 1st respondent establishment cannot be saddled with any responsibility to pay the contribution in respect of construction workers and workers engaged for maintenance of the machinery of the establishment. It is not in dispute that admittedly, the 1st respondent establishment is under the coverage of the provisions of the Act from 01.03.1999. Viewed thus, this Court finds that the Labour Court was justified in holding that no contributions are payable even on this score.
