SNP leader Ian Blackford was the politician given the boot by Speaker John Bercow.
Mr Bercow shouted "not now" and demanded the SNP chief resume his seat - eventually expelling him for the rest of the day when he refused.
Today's walkout from Prime Ministers Questions by me and my SNP colleagues was an act of defiance, a protest motivated by despair that Scotland's voice was being silenced at a time when we are at risk of significant fallout from Brexit and a deceitful grab of our devolved powers.
We all recall the prime minister giving her commitment that she would treat Scotland as part of a "union of equals".
"Yet, last night, she pressed ahead with a power grab in direct opposition to Scotland's elected parliament".
"I really do hope that the people of Scotland listened very carefully to what the PM said", he said.
"This powergrab occurred when MPs from Scotland were not even given the courtesy of debating it last night, it's a democratic outrage".
Blackford concluded: "I have no options but to ask that this house now sits in private".
He insisted what had happened in the Commons was a "democratic outrage", adding: "Without debate, without the voices of Scottish MPs being heard, the government pushed through these amendments to rip out the powers from the Scottish Parliament".
The unprecedented event brought PMQs to a temporary halt as Mr Bercow refused his demands.
The passing of the EU Withdrawal Bill meant powers which were supposed to return to the Scottish Parliament after the United Kingdom leaves the EU would go to Westminster for a period of seven years, a move which SNP MPs broke with the Sewel convention that changes to devolution would not occur without the consent of the Scottish Parliament. "But the Prime Minister has ignored Scotland".
Opponents said the move was planned well in advance, taking place during prime minister's questions, the highlight of the parliamentary week. Look at this morning's interview with Scottish secretary David Mundell, who was repeatedly asked why there was next to no time given for debate of issues related to devolution.
While Conservatives at Westminster say some of these must come to Parliament to allow for common frameworks to be established in areas such as agriculture and environmental regulations, ministers at Holyrood fear the powers of the Scottish Parliament could be restrained for up to seven years.
SNP leader and Scottish First Minister Nicola Sturgeon tweeted minutes later that she was "right behind" her party's MPs.
