The Court further observed that where there are a large number of industrial concerns of the same kind in the same region it would be proper to put greater emphasis on the industry part of the industry cum region principle as that would put all concerns on a more or less equal footing in the matter of production costs and therefore in the matter of competition in the market and this will equally apply to clerical and subordinate staff whose wages and dearness allowance also go into calculation of production costs : but where the number of comparable concerns is small in a particular region and therefore the competition aspect is not of the same importance, the region part of the industry cum region formula assumes greater importance particularly with reference to clerical and subordinate staff and this was what was emphasised in the French Motor Car Cos((1) case where that company was already paying the highest wages in the particular line of business and therefore comparison had to be made with as similar concerns as possible in different lines of business for the purpose of fixing wage scales and dearness allowance.
