Rep. Bill Pascrell, a New Jersey Democrat, filed letters with the state bars of Arizona, Michigan, New York, Nevada, and Pennsylvania, seeking the disbarment of Giuliani and 22 other lawyers working for the Trump campaign.

He said the lawsuits — none of which have succeeded in court so far — violate rules forbidding frivolous litigation, as well as “conduct involving dishonesty, fraud, deceit, or misrepresentation.”…

Most often, disbarment is the result of a clear ethical violation, like a lawyer cheating from a client, comingling finances, or receiving a felony conviction. There is also a range of lesser sanctions and forms of rebuke, like private or public reprimands, or suspensions.

While legal experts and virtually every judge have found Trump’s election lawsuits to be without merit, judges still tend to allow a lot of leeway for creative legal arguments. Those sorts of arguments are important in getting precedents overturned even when the law hasn’t changed, as with Thurgood Marshall’s court battles over segregation in the 1940s and 1950s, as Bloomberg Law noted.
