The assembly witnessed unruly scenes as the PDP and other opposition parties did not allow the House to function over their demand for setting up new administrative units in "ignored" areas of the state, forcing adjournment for the day.
Chief Minister Omar Abdullah condemned the opposition action as "shameful behaviour."
The PDP members first trooped into the well alleging discrimination against certain areas which had not given new administrative units, which was followed by a scuffle between them and security staff in which Mustaq Ahmed Shah, a PDP MLA, got injured.
As the assembly began its proceedings for the day, PDP members led by Mehbooba Mufti stood up from the benches holding placards depicting discrimination in setting up new administrative units and trooped into well of the House.
Speaker Mubarak Gul called the watch-and-ward staff into the well of the House, leading to scuffle between them and PDP members for nearly half an hour amid uproarious scenes.
PDP MLAs were joined by members of BJP, Jammu and Kashmir National Panthers Party (JKNPP) and Independent members Hakeem Yasin and Engineer Rashid protesting alleged discrimination against their areas by the Omar Abdullah government.
Even Deputy Speaker Sartaj Madni was seen standing in protest as the opposition demanded new administrative units.
The Speaker's requests for calm in the House failed to bring order, forcing him to adjourn the House first for 15 minutes, then once more, before adjourning it for the day.
"We will not allow the House to run unless and until our demands of inclusion of our areas in the list of the new administrative units are not met by the government," Mufti told reporters.
When the House reassembled after the second adjournment, Shah, who represents Tral Assembly segment, got injured when he got pushed by a Marshal and fell on a chair.
PDP members and watch and ward staff rushed him to doctors in a medical unit in central hall, and later referred him to GMC hospital for further medical treatment. Doctors said he suffered injuries owing to his fall on the chair.
Tempers ran high as PDP MLAs resorted to throwing of chairs, tables and mikes causing ruckus forcing the Speaker to adjourn the House for the day. Some went up on the reporting tables too. Rashid also uprooted a mike.
Commenting on the chaos, Omar wrote on his Twitter account, "Seems they (opposition) really are totally shaken up by our decision to create so many new administrative units which has been well received".
"Want to see shameful behaviour of elected representatives - check out the opposition in the J&K assembly standing on tables," he said.
