Nine AIADMK members were on Monday suspended from the Assembly till the end of the session on January 13 for disrupting the address of the Governor on Friday, but the Speaker's action saw two walkouts and a mock session by the Opposition.
Finance Minister and leader of the House K Anbazhagan moved the resolution seeking action against the AIADMK members which was adopted by voice vote.
The suspensions, including those of senior leaders and former ministers C Ve Shanmugam and V Jayaraman, for the rest of the five-day session triggered noisy protest by AIADMK, whose members trooped out of the House.
The Left and MDMK members also joined the AIADMK when it staged the second walkout after their demand for raising the suspension issue was disallowed by Speaker R Avudaiappan.
The opposition members then squatted at the entrance and staged a 'mock Assembly' session with AIADMK leader and former minister T Jayakumar acting as the "Speaker".
Various issues including Niira Radia tapes (relating to corporate lobbying on telecom portfolio) were "discussed".
Efforts by the police to clear the place met with strong protests from angry AIADMK members, who told the securitymen that they did not have the powers to enter the Assembly premises, following which they left.
Slogan shouting AIADMK-led opposition members were evicted from the House enmasse on Friday when they tried to disrupt the Governor's customary address by raising corruption issues, including 2G spectrum allocation scam.
Later, the AIADMK members told reporters that the opposition was not allowed enough opportunities to raise various issues.
"Our leader (J Jayalalithaa) had said yesterday that there was a battle going on between the good and evil. That is happening inside the House too. We are not allowed to speak or raise people's issues," AIADMK MLA Badar Saeed said.
