He said that the Congress was in power for 27 years but did nothing to empower the OBC Commission.
Yesterday it proposed an amendment seeking increase in the number of members of the proposed commission, "which shows it did not want the bill to be passed", he alleged.
"I want to ask the Congress today if it is against the OBCs," the minister of state for social justice and empowerment asked.
When the House took up the bill, whose passage required two-third majority of those present and voting in the 245- member House, the ruling benches were clearly short of several members.
The amended bill will now have to be returned to the Lok Sabha for its fresh approval. The Lower House had already passed the bill but in the Upper House it had been referred to a Select Committee as the Opposition had wanted more scrutiny.
