Rudy Giuliani has been disbarred in New York

• Rudy Giuliani has been disbarred in New York over efforts to boost Donald Trump's 2020 election-fraud claims.
• The former NYC mayor and personal attorney to Trump was disbarred effective immediately.

Rudy Giuliani, the man once heralded as "America's Mayor" and a former federal prosecutor who made his name going after the mob, has been disbarred in his home state of New York.

A New York appeals court ruled Tuesday that Giuliani, who served as a personal lawyer to former President Donald Trump, be disbarred "effective immediately" over his efforts to boost Trump's baseless 2020 election-fraud claims.

Giuliani, the appeals court wrote in its 31-page ruling, "is disbarred from the practice of law, effective immediately, and until the further order of this Court, and his name stricken from the roll of attorneys and counselors-at-law in the State of New York."

The 80-year-old former New York City mayor can no longer practice law in New York over his "demonstrably false and misleading statements to courts, lawmakers, and the public at large in his capacity as lawyer for former President Donald J. Trump and the Trump campaign in connection with Trump's failed effort at reelection in 2020," the appeals court wrote.

"These false statements were made to improperly bolster respondent's narrative that due to widespread voter fraud, victory in the 2020 United States presidential election was stolen from his client," the court said.

"The seriousness of respondent's misconduct cannot be overstated," it added.

Giuliani, the court wrote, "flagrantly misused his prominent position as the personal attorney for former President Trump and his campaign, through which respondent repeatedly and intentionally made false statements."

He also "baselessly attacked and undermined the integrity of this country's electoral process," the court said. "In so doing, respondent not only deliberately violated some of the most fundamental tenets of the legal profession, but he also actively contributed to the national strife that has followed the 2020 Presidential election, for which he is entirely unrepentant."

Attorneys for Giuliani did not immediately respond to a request for comment.

Ted Goodman, a spokesperson for Giuliani, criticized the disbarment ruling in a statement to Politico and said Giuliani would appeal.

"Members of the legal community who respect the rule of law in this country should immediately come forward and speak out against this politically and ideologically corrupted decision," Goodman said.

"We will be appealing this objectively flawed decision in hopes that the appellate process will restore integrity into our system of justice," he added.

Giuliani is facing criminal charges in Arizona and Georgia related to efforts to overturn the 2020 election results.

Giuliani filed for Chapter 11 bankruptcy last year in New York days after he was ordered by a federal jury to pay $148 million to two Georgia election workers he defamed.
