Sidney Powell's defense in the $1.3 billion Dominion lawsuit may be used against her in Michigan sanctions effort

• Michigan's attorney general said Sidney Powell made "stunning admissions" in Dominion's lawsuit against her.
• The state said those admissions should be further reason to sanction Powell.
• Powell and others are facing defamation lawsuits for their election-fraud claims.

Sidney Powell's defense in Dominion Voting Systems' $1.3 billion defamation lawsuit against her is being used against her in another court case over her unsubstantiated claims of fraud in the 2020 election.

Powell, an attorney who became widely known for filing lawsuits and floating conspiracy theories about election fraud, said in her defense that "no reasonable person would conclude that the statements were truly statements of fact."

Michigan Attorney General Dana Nessel said Powell's statement was another reason a federal court should approve sanctions against her, Forbes first reported on Wednesday, citing a legal filing.

Powell "made a series of stunning admissions" in the Dominion lawsuit about her election-fraud claims, "many of which also were made to this Court," the filing said.

Nessel had asked a federal court in January to sanction Powell and three other attorneys over a lawsuit in Michigan requesting that the state overturn its election result.

In her filing to the federal court this week, Nessel said Powell's defense in the Dominion lawsuit proved that the attorney's behavior "warrants sanctions because it unreasonably multiplied the proceedings in this case and abused the judicial process."

Powell did not respond to Insider's requests for comment.

Powell, who was hired and then fired by President Donald Trump's campaign, accused the election-technology companies Dominion and Smartmatic, which is also suing her, of using their voting machines to falsify votes.

Her law firm filed lawsuits in Michigan, Arizona, Georgia, and Wisconsin, all of which it lost.

Powell isn't the only one facing legal repercussions for election claims: Trump's lawyer Rudy Giuliani, Fox News, and MyPillow CEO Mike Lindell are also facing defamation lawsuits from Dominion and Smartmatic.
