Briefing the governor, the SAD president said "never before" in the history of the Vidhan Sahba had the opposition been treated so "ruthlessly".
He said not only were Opposition members "beaten up" but even women members were "injured and their clothes torn" by staff deputed to throw them out of the assembly by the Speaker.
Sukhbir also requested the governor to convey his displeasure to the Congress government.
"What was even more intolerable was that turbans of Sikh legislators were tossed and trampled upon," he said.

During the last 10 years of the SAD-BJP rule no such action was taken, Sukhbir later told reporters here.
In fact, there were instances when the Opposition occupied the chair and even sat in the Vidhan Sabha for the entire night, he said.
"But still no action was initiated against them. This is the first session of the new Vidhan Sabha. In this session only the Speaker has named 38 members and ordered they be taken out of the premises of the august house. This has never happened earlier," he added.
The first budget session of the Assembly under the new Amarinder Singh government was adjourned sine die today.
