On April 20, the Iowa Secretary of State filed a four-page brief with the U.S. District Court in Iowa Libertarian Party v Pate, s.d., 4:19cv-241. This the case in which the court struck down the March petition deadline for independent candidates, and the nominees of unqualified parties. The deadline had been moved from August to March in 2019. The Secretary of State’s brief expresses the opinion that the result of declaring the March deadline unconstitutional is that the old August deadline is now back in force.

Therefore, the 2022 petition deadline is August 19.
