792. In our opinion, it is not a question of permissibility or desirability of such test but one of proper and more appropriate identification of a class — a backward class. The very concept of a class denotes a number of persons having certain common traits which distinguish them from the others. In a backward class under clause (4) of Article 16, if the connecting link is the social backwardness, it should broadly be the same in a given class. If some of the members are far too advanced socially (which in the context, necessarily means economically and, may also mean educationally) the connecting thread between them and the remaining class snaps. They would be misfits in the class. After excluding them alone, would the class be a compact class. In fact, such exclusion benefits the truly backward. Difficulty, however, really lies in drawing the line — how and where to draw the line? For, while drawing the line, it should be ensured that it does not result in taking away with one hand what is given by the other. The basis of exclusion should not merely be economic, unless, of course, the economic advancement is so high that it necessarily means social advancement. Let us illustrate the point. A member of backward class, say a member of carpenter caste, goes to Middle East and works there as a carpenter. If you take his annual income in rupees, it would be fairly high from the Indian standard. Is he to be excluded from the Backward Class? Are his children in India to be deprived of the benefit of Article 16(4)? Situation may, however, be different, if he rises so high economically as to become — say a factory owner himself. In such a situation, his social status also rises. He himself would be in a position to provide employment to others. In such a case, his income is merely a measure of his social status. Even otherwise there are several practical difficulties too in imposing an income ceiling. For example, annual income of Rs 36,000 may not count for much in a city like Bombay, Delhi or Calcutta whereas it may be a handsome income in rural India anywhere. The line to be drawn must be a realistic one. Another question would be, should such a line be uniform for the entire country or a given State or should it differ from rural to urban areas and so on. Further, income from agriculture may be difficult to assess and, therefore, in the case of agriculturists, the line may have to be drawn with reference to the extent of holding. While the income of a person can be taken as
