New Delhi: Demanding reservation for SCs/STs and OBCs in the faculty of the country's top institutions, BSP and several other parties today stalled passage of a bill in Rajya Sabha, which seeks to upgrade IIIT, Kancheepuram to institute of national importance.

The trouble got aggravated after HRD Minister Kapil Sibal said that while there is reservation in admissions in the institutions of national importance, there was no such provision in the case of faculty.

On the penultimate day of Monsoon session, Sibal moved the Indian Institute of Information Technology, Design and Manufacturing, Kancheepuram Bill for passage.

As Deputy Chairman K Rahman Khan was about to ask for a voice vote for passage of the bill without discussion, Jesudasu Seelam (Cong) stood up, raising the issue of reservation in the institutes of national importance.

This prompted the BSP, RJD and LJP along with the Left parties to seek proper discussion on the bill.

S C Mishra (BSP) accused the Congress and the BJP of reaching an understanding for passage of the Bill without debate.

Amidst acrimonious scenes, Khan adjourned the House for 15 minutes in the afternoon.

When the House reassembled and Sibal clarified that there was no provision of reservation in the faculty, members from the BSP, RJD and LJP rushed into the well and shouted slogans against the Government.

At this stage, BJP also expressed displeasure with Sibal's reply. The Chair then adjourned the House for 30 minutes.

Senior ministers, including P Chidambaram, Sibal and Pawan Kumar Bansal, were visibly upset with Seelam whose question to the government prompted BSP and others to stall the proceedings.

The bill, which has already been passed by the Lok Sabha, could not be taken up later, as the House was adjourned for the day after Home Minister's statement on Delhi High Court blast.
