 The NCBC also recommended the sub-division of OBCs into "backward", "more backward", and "extremely backward" blocs and divide 27% quota amongst them in proportion to their population, to ensure that stronger OBCs don't corner the quota benefits.The Supreme Court of India defined the "creamy layer", quoting an Indian governmental office memorandum dated 8 September 1993.The term was originally introduced in the context of reservation of jobs for certain groups in 1992.
