"We have to sort it (creamy layer issue) out. The matter will have to go to the Cabinet," Singh told reporters, shortly after the apex court upheld the 27 per cent quota for OBC students in Centrally funded institutions of higher learning including IITs and IIMs.

Singh said he would certainly take the creamy layer issue to the Cabinet and would also try to meet Prime Minister Manmohan Singh in this regard.

Suggesting that the OBC quota could be put in place in a staggered manner, he said "our effort is to implement it as soon as possible" and nothing now stood in the way on its implementation.

Singh said it also depended on the available infrastructure in various institutions which should be a determining factor on the implementation. Law also provided for staggered implementation, he said adding "we will try whatever we can do".

Asked whether the government could overrule the decision of the Supreme Court on the creamy layer issue, he shot back "how can the government overrule". "This is a very historic judgement. Hundreds of students belonging to OBC category will be benefited by it," Singh, who championed the cause of OBC reservation, said.
