Epoch-making verdict of Supreme Court: Subcategorising SCs remains difficult
The Supreme Court ruled on the categorisation of Scheduled Castes in the Punjab Vs Davinder Singh case, ending a two-decade debate. The court allowed states to differentiate SCs based on rational data and supported the principle of excluding the '...

The AP Act and Usha Mehra Commission
The argument began with the Andhra Pradesh Scheduled Castes (Rationalisation of Reservation) Act, 2000, which formed 4 sub-categories of the 59 Scheduled Castes to guarantee equitable reservation benefits.
It distributed 15% SC reservations as follows: SC-A: 1%, SC-B: 7% (with Madiga caste), SC-C: 6% (with Mala caste), SC-D: 1%. Though upheld by the AP HC, the SC quashed the legislation in EV Chinnaiah case (Justice Santosh Hegde) on the grounds that the state legislature is not competent to change the SC list and that SCs are a homogenous group historically victimised by untouchability.
The Union Government established the Usha Mehra Commission to explore the constitutional, statutory, and legal implications of sub-categorizing Scheduled Castes in Andhra Pradesh at the request of the AP Assembly. All quota advantages went to a few castes, leaving the majority of the Scheduled Castes out in the cold, according to the Commission (2008). The Commission suggested adding clause (3) to Article 341 of the Constitution to subdivide Scheduled Castes.
The Union government sought state input on the report. Fourteen states opposed sub-categorisation (Gujarat, Odisha, Kerala, West Bengal), 7 supported it (AP, Telangana, Karnataka, Punjab, Haryana), and most importantly (5) states with nearly 50% of the SC population -- Bihar, Maharashtra, Rajasthan, Tamil Nadu, and Uttar Pradesh-were undecided. States and Union territories have different social, educational, and economic realities. Thus, what applies to Andhra Pradesh cannot apply to other states.
The Supreme Court order is historic for three reasons: It is now clear that Presidential Notifications under Article 341(1) of the Constitution can distinguish scheduled castes.
The differentiation must be rational and supported by facts. The data should show that the caste receiving better treatment is under-represented.
Scheduled Castes and Tribes will follow the creamy layer principle, although with different requirements than OBC.
Implications
There has to be a scientific survey of the representation of these communities in the public service and other benefits of reservations. This is an onerous task, since the survey has to prove the extent of benefits which each community has taken so far. Each state has to conduct this study at their level duly following research methodology. This would also strengthen the demand for a comprehensive socio-economic caste census.
Most importantly, exclusion of the 'creamy layer' from the SC reservations is bound to result in agitations. This is because the basis for categorizing some communities as SCs is due to the social exclusion and NOT for economic backwardness. This will emerge as contentious issue even if the sub-categorisation is settled.
Legal road blocks are now cleared, but the path for sub categorisation of SCs, is long and arduous.
