New Delhi, Sep 24 (IANS): Rajya Sabha Chairman Venkaiah Naidu, in his valedictory remarks ahead of the house being adjourned sine die on Wednesday, made some serious observations about Sunday's ruckus in the Rajya Sabha that got eight MPs suspended.

"For the first time in this history of this august House, a notice of motion for removal of the Hon'ble Deputy Chairman has been given. It had to be rejected for the reasons I have elaborated while doing so," Naidu said, calling the "developments" "unprecedented" and "painful".

"I don't want to go into details of those unpleasant turn of events. All that I like to do is to appeal to all of you from the depth of my heart to kindly ensure that such unseemly behavior is not repeated," he urged.

Calling the ruckus "unpalatable", he reminded: "To protest is the right of the opposition. But the question is how should it be done?"

"But if boycott is done for a longer period, it amounts to leaving the very platform that enables you to effectively convey your ideas and contesting those of others. I request all members to keep this in mind."

However, there were high points too. Naidu said that 25 Bills have been passed and six Bills have been introduced in this very short span of time in the upper house.

The productivity of the house during this session has been 100.47 per cent, he informed.

"(As much as) 22 hours 3 minutes time has been spent on discussing the government's legislative proposals during these 10 sittings. This comes to a record 57 per cent of the total functional time of the House during this session," an otherwise upset Naidu said with visible happiness.

Meanwhile, 1,567 unstarred questions were replied to in writing by the government during these 10 sittings.

Members also raised issues of urgent public importance through 92 Zero Hour and 66 Special Mentions.

Both houses of Parliament were adjourned sine die on Wednesday -- eight days before their scheduled end on October 1 -- due to increasing Covid-19 cases.
