The BJP members asked Speaker B B L Butail to give his ruling on the privilege motion they had moved against the chief minister.
They were referring to the reported statement of Singh about the BJP MLAs on August 4.
Amidst noisy scenes, the Speaker said he had received the notice and that the issue should not be raised in the House. As the Speaker tried to persuade the BJP members, they started raising slogans and staged a walkout.
BJP chief spokesman Rajiv Bindal said Singh's remark was an "insult of the Assembly and the Constitution".

Dhumal said that during the winter session, Singh talked about chopping off the fingers of MLAs, during the budget session he dubbed the BJP MLAs as "bonded labourers" and this time again he has made derogatory remarks.
