On April 1, the apex court had asked the Centre why it allegedly ignored the advice of the National Commission for Backward Classes (NCBC) to keep the Jat community away from reservation benefits.
The court had also said that "the matter is serious" and had directed the Ministry of Social Justice and Empowerment to place before it all the material, records and files pertaining to the decision, to see "whether there was application of mind or not" while issuing the March 4 notification.
The notification included Jat community in OBC list in Bihar, Gujarat, Haryana, Himachal Pradesh, Madhya Pradesh, Delhi, Rajasthan (two districts of Bharatpur and Dholpur), Uttar Pradesh, and Uttarakhand.
OBC Reservation Raksha Samiti in its plea had contended that as a result of the notification, Jats will be like a "creamy layer" in the OBC list and will take away the seats and posts in schools, colleges and government jobs from other community.
Besides the organisation, three other individuals from Delhi - Ram Singh, Ashok Kumar and Ashok Yadav - belonging to OBC category have also challenged the Centre's notification.
The petitioners, referring to several empirical studies and survey, have contended that Jat community being a socially forward caste will consume substantive portion of the quota of OBC reservation which will deprive the deserving people of other backward classes of the benefit of reservation.
They submitted that people of Jat community have performed much better than those of other castes and the number of those who have been selected in the prestigious civil services exam of UPSC is much higher than the number proportionate to their population.
They have sought a direction holding that Jat community is not a backward class and not entitled to be included in the list of OBC and annexed findings of the NCBC which in its February 26, 2014 report had rejected the Centre's request for recommending inclusion of Jat community in the central list of backward classes.
