I wholeheartedly support this clause. This is a very wholesome provision, but my difficulty is that the term “backward classes of citizens” is not defined anywhere in the whole Constitution. This phrase has been used in some places and, in my humble opinion, it does not convey any definite meaning. It is so loose and vague that it might be interpreted differently by different Governments or by different authorities. In article 10(3) it is stated :
“Nothing in this article shall prevent the State from making any provision for the reservation of appointments or posts in favour of any backward class of citizens who, in the opinion of the State, are not adequately represented in the services under the State“.
