The term creamy layer was first coined by Justice Krishna Iyer in 1975 in State of Kerala vs NM Thomas case, wherein he observed that the benefits of reservation are snatched away by the top creamy layer of the 'backward' caste or class, thus keeping the weakest among the weak always weak.
The Creamy Layer is used to Differentiate Socially economically developed Persons in a caste from those who are Deserving of Reservation and Empowerment. . It is only applicable to OBCs, SC and STs are exceptions to this differentiation. This is estimated using annual Income of a Family- Currently It is 8 lakhs, meaning if your family is earning 4 lakhs/annum and you belong to an OBC caste, you are eligible for reservation. But if your family has Income above 6 lakhs, then you are not Eligible for reservation. This allows the Benefits of reservation to seep through to the poor.
