The main contentions of the Association were that the total pay ' packet of the workmen in Rayon and Artificial Silk industry in the, local area of Greater Bombay was Rs. 190.12 per month of 26, working days, that dearness allowance to the extent of 80 per cent neutralization was automatically responsive to the rise in the cost of living and, therefore, there was no real fall in the pay packet consequent on the rise in the cost of living, that the workmen had received an ad hoc increase of Rs. 5.20 per month of 26 working days from February 1, 1962, and that this has been further raised to Rs. 6.50 from February 1, 1964, that the base for neutralization which was Rs. 30/ should not and ought not to be changed to Rs. 36.50 as demanded by the Sabha, that the demand was beyond the capacity of most of the 55 units concerned, that the dearness allowance paid in the other industries in the region cannot furnish any relevant criterion as the financial position of these units was quite different, that over the years, the position of the industry has steadily deteriorated, that on account of the paucity of foreign exchange, restrictions on import of the required machinery, the non availability of the necessary types of raw materials, the high cost of yam, the heavy excise duty on indigenous yarn, the industry has been declining, that the import on nylon yarn was canalised through the State Trading Corporation of India and it kept for itself a very high profit margin, that the price of raw materials in the industry has gone up, that prior to March, 1970, the excise duty on processed yarn and artificial silk fabric varied from 9 paise to 30 paise per square metre whereas from March, 1970, onwards, the was a steep rise in the excise, duty per square metre and therefore the industry cannot bear any further burden and that in any event, the demand for 100 per cent neutralization is unwarranted As already stated, the Industrial Court, after evaluating the materials produced by parties, came to the conclusion that the employees in the Silk and Art Silk Industry should be granted dearness allowance at the rate of 99 per cent neutralization of the rise in the Bombay Consumer Price Index 106 (old series) on the basis of the minimum basic wage of Rs. 30/ per month of 26 working days with effect from January 1, 1971.
