Opposition Leader Dr Keith Rowley has been suspended from Parliament for the remainder of this parliamentary term.
He is the first opposition leader to be suspended in this manner from Parliament.
A Government motion calling for Rowley's censure and suspension from the House, which began earlier in the day, was approved around9.20 pm.
The motion was passed with 24 Government members voting for it and only Independent Liberal Party leader Jack Warner voting against, the other PNM MPs having walked out the House earlier. There were no abstentions.
Yesterday's vote followed the recent passing of another no confidence motion against Rowley, which questioned his leadership abilities.
In wrapping up the debate, Leader of Government Business Dr Roodal Moonilal noted thatall members of the Opposition, led by Rowley, had walked out "kicking and screaming" during the debate.
He said they had walked out on the no confidence motion but promised to sit through this one, focusing not on the emails themselves but their contents.
The motion centered on 31 emails Rowley read out in Parliament two years ago, in May 2013.
The emails, purporting to come from Prime Minister Kamla Persad-Bissessar and other members of her Cabinet, revealed a plot to murder a journalist, bug the Office of the Director of Public Prosecutions and commit other acts of misconduct in public office.
Persad-Bissessar said she had instructed Moonilal to bring the motion against Rowley for what she said were reckless and unsubstantiated allegations designed to destabilise the Government and incite revolt among citizens.
The Government brought the motion with the backing of notified reports from Google International, US computer expert John Berryhill and the US Justice Department, which all said the emails were fake.
Moonilal, in winding up the debate, said it appeared Rowley had not discussed the debate with his colleagues and took them by surprise with the walkout.
"They started to pass a piece of paper around and then walked out," he said.
Moonilal said PNM Diego Martin Central MP Dr Amery Browne was preparing notes for his presentation and was taken by surprise. So too was Diego Martin North East MP Colm Imbert, he said. He said just before the walkout, Rowley got up and started to yell angrily across the floor.
"I quickly looked around to ensure there was no teacup or glass around," he said, referring to the incident in Parliament's tea room between Rowley and Fyzabad MP Chandresh Sharma.
"Ten seconds more and we would have had to suspend the House," he said.
Moonilal said it was a "landmark day."
"When history looks back they will judge us on whether we held up the honour and dignity of Parliament."
He quoted the now famous statement of Tobago House of Assembly Chief Secretary Orville London, which he made after Rowley read out the emails in Parliament. London had said if and when evidence come out on the emails, one man or one woman would be left standing.
"Today, one woman from Siparia has been left standing," Moonilal said.
He vowed this was not the end of the Emailgate, renamed Rowleygate, fiasco, however.
He promised Government will chase Rowley down with the reports they have stating the emails were fake in Port-of-Spain, Diego Martin, Roxborough and everywhere they go on the 2015 general election campaign trail.
"We will take the truth and hang it around his neck.
"It is not the last day. The public must judge him. If you lie, you must say goodbye."
Quoting Shakespeare, Moonilal said, "What a tangled web we weave when, first, we sought to deceive. He (Rowley) is the maker of his own destiny."
