Jeff Clark is fighting his defeat in the DC Circuit in a bar disbarment case

Former President Donald Trump's top environmental lawyer wants a federal appeals court to reconsider his attempt to block an ethics case brought against him for his role in trying to undermine the 2020 election.

In a motion for retrial filed Monday, lawyers for Jeffrey Bossert Clark argued that a three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit erred in refusing to send the ethics case to federal court. They asked that the court's entire slate of active judges reconsider the case in what is known as an en banc retrial.

Clark's team said the D.C. Circuit erroneously found that Clark missed a 30-day deadline to transfer civil cases to federal court, arguing that the Supreme Court has ruled that disciplinary actions against opposing counsel are “quasi-criminal” in nature.

“[E]”Review by the full court must be granted to reverse the panel's decision and instead find that the removal of a quasi-criminal matter at any time prior to trial in a case where there is no indictment is timely,” Clark's lawyers wrote.
