Ramji,
You would have heard this “adh jal gagari chhalkat jaay”. This is what happening here, a complete quackery.
3) Nothing in this article shall prevent the State from making any special provision for women and children.
_10[(4) Nothing in this article or in clause (2) of article 29 shall prevent the State from making any special provision for the advancement of any socially and educationally backward classes of citizens or for the Scheduled Castes and the Scheduled Tribes.]
Here in the above our constitution is doing justice to the oppressed classes, oppressed since ages. It cannot be called favoritism.
It is an endeavor to equalize and to protect the comparatively weaker section from the stronger section who are equipped with greater resources than those oppressed class of people.
Law always used to be with weaker side since humanity matters more than anything.
Here for instance I am pasting (and underlined and highlighted the salient features) excerpt observation of Hon SC from a judgment of Hon SC, full judgment can be downloaded from the link at the bottom.
“4. The special provisions made for the resumption of granted lands originally granted to the members of Scheduled Castes and Scheduled Tribes and restoration of the same to the original grantees or their heirs and legal representatives and falling them to other members of these communities do not infringe Article 14 of the Constitution. This Act has undoubtedly been passed for the benefit of members of the Scheduled Castes and Scheduled Tribes who are recognized as backward citizens and weaker sections in the country. There cannot be any manner of doubt that persons belonging to Scheduled Castes and Scheduled Tribes can be considered to be separate and distinct classes particularly in the matter of preservation and protection of their economic and educational interests. In view of the peculiar plight of these two classes, the Constitution in Art. 15 (4) makes specific mention of these two classes and in Art.16 (4) speaks of backward class of citizens. One of the directive principles as contained in Art. 46 of the Constitution enjoins that "the State shall promote with special care and educational and economic interests of the weaker sections of the people and in particular of the Scheduled Castes and Scheduled Tribes and shall protect them from social injustice and all forms of exploitation." The object of this Act is to protect and preserve the economic interests of persons belonging to Schedule Castes and Scheduled Tribes and to prevent their exploitation. For the purpose of the present Act, the classification has a clear nexus to the object sought to be achieved.”

Now provision of article 15(3) can be analyzed or understood in the light of above observation of Hon SC.
