New Delhi, Aug 9 (IANS): The Rajya Sabha was adjourned Thursday after Bahujan Samaj Party (BSP) members raised the issue of reservation for Scheduled Castes and Scheduled Tribes groups in promotions in government jobs.

The upper house lost the important question hour for the second day of the monsoon session.

The Supreme Court had in April overruled the Uttar Pradesh government's decision to provide reservations in government job promotions. The BSP, which was then in government, had raised the issue in the budget session demanding a constitutional amendment to provide for such quotas.

BSP leader Mayawati raised the issue as soon as the house met for the day, blaming the government for not taking action as promised.

Even as Minister of State in Prime Minister's Office V. Narayanasamy promised a meeting would be called in the current session, BSP members refused to be pacified and trooped near chairman Hamid Ansari's podium.

Ansari then adjourned the house till noon.
