Raising the point in the zero hour, Minister for Welfare of Handicapped Ambika Chaudhary said BJP MLAs blocked the passage leading to the Speaker Mata Prasad Pandey's chair on June 19 which amounted to contempt of the Chair.
The Minister also said that the saffron party members later stayed out of the House while the national song was being played, showing disrespect to it.
Terming the act condemnable, Chaudhary said the party which claims itself "to be the champion of national song have insulted it" and sought strict action against them.
Mahana lashed out at the ruling party members asking if they and their supporters "would tell us what is right and what is wrong".
