A team of lawyers behind a series of failed post-election challenges received their first court-ordered sanctions this week, a move that could trigger future disciplinary proceedings against the attorneys.

U.S. District Judge Linda Parker of the Eastern District of Michigan’s scalding 110-page opinion against the “Kraken” lawyers, including Sidney Powell, Lin Wood, Howard Kleinhendler and several others, refers the attorneys to disciplinary authorities to investigate them for potential suspension or disbarment. Donald Campbell, who represents most of the sanctioned attorneys, said Thursday that they disagree with the ruling and plan to appeal it.
