The Arizona Free Enterprise Club filed a lawsuit over the constitutionality of the Make Elections Fair Act, a ballot initiative that would institute open primaries in the state. The group says it violates the Arizona Constitution by having several amendments in a single ballot measure.
The defendants involved include Secretary of State Adrian Fontes and political committee Make Elections Fair AZ.
The Arizona Free Enterprise Club points to the other changes made by the initiative, such as the integration of ranked choice voting in the general election.
Earlier this month, Make Elections Fair AZ alleged Republican legislators misled voters about the ballot measure.
The Arizona Free Enterprise Club has also filed a lawsuit alleging more than half of petition signatures used to get the open-primary measure on the November ballot are illegal.
