A lawsuit has been filed in federal court challenging the constitutionality of campaign finance rules passed in a 2020 voter initiative in Alaska.

The newly filed suit focuses on the disclosure requirements of the initiative, stating the requirements hinder free speech and could lead to reprisals against donors.

The disclosure requirements include a disclaimer and reporting for ads concerning contributions greater than $2,000 given to or received by independent expenditure groups.

The embattled voter initiative already faced challenges in court over the open primary system and ranked-choice voting provisions of the law.
