A five-judge bench of the Supreme Court has referred to a larger constitution bench the question on sub-classification of Scheduled Castes and Scheduled Tribes for the purpose of granting reservations. The reference was made as the bench comprising Justices Arun Mishra, Indra Banerjee, Vineet Saran, M.R. Shah and Aniruddha Bose disagreed with an earlier judgment of 2005 given by another five-judge bench in E.V. Chinnaiah versus State of Andhra, which had held that SCs formed a homogenous group and sub-classification would not only be against the Constitutional provision under Article 341 but also violate Article 14.
