In King v. Whitmer, No. 20-13134, Judge Linda Parker issued a 110 page opinion sanctioned several lawyers who filed the complaint and the amended complaint under Rule 11, the Court’s inherent authority and 28 U.S.C. §1927. This opinion is very significant and it may cause changes in the way election law is practiced in the future. The Court found that the allegations in the Complaint lacked a good faith basis in law and fact and that the lawyers vexatiously multiplied the proceedings. The court used every possible ground to support the sanctions award and made credibility findings.

At the time these lawsuits were brought, they appeared to me to be reckless and risky. It is one thing to allege that a voter was disenfranchised. It is another thing all together to allege that the entire election was a fraud.
