A state court ordered a permanent halt to Kansas' dual voter registration system, the American Civil Liberties Union of Kansas announced Friday.

The dual system allowed some Kansans to vote for federal offices, but not state and local offices, due to how they registered to vote, according to the ACLU. The ACLU challenged the dual system, and asked the Third Judicial District in Topeka to permanently block it.

Kansas Secretary of State Kris Kobach attempted to formalize the system via an administrative rule, which led to the ACLU to ask the court to block the dual system.

Friday, Judge Larry Hendricks ruled in favor of the ACLU, ruling Kobach "simply lacks the authority to create a two-tiered system of voter registration," according to the ACLU.

In June, Shawnee County District Judge Franklin Theis reiterated that Kobach cannot stop Kansans from voting in state and local elections simply because they registered to vote using federal forms. Those federal forms do not require proof of citizenship like Kansas does in its registration process.

Sophia Lakin, a staff attorney with the ACLU's Voting Rights Project called the ruling a victory.

"This ruling is a victory for Kansas voters and a stinging rebuke of Secretary Kobach's repeated efforts to improperly use his authority to obstruct their access to the ballot," Lakin said in a statement. "This decision recognizes that Kansans' right to vote in state and local elections should be honored, no matter what registration for they used."

According to the ACLU, at least 19,000 Kansans who registered to vote through the Division of Vehicles or by the federal national mail registration form are affected by the ruling. One of those affected is 90-year-old Marvin Brown, an Army Air Corps veteran. Brown registered to vote by submitting a complete federal form, according to the ACLU. He was later told he could vote in federal elections, but was prohibited from voting in state and local elections unless he showed additional proof of citizenship.

"It's wrong that a bunch of so-called leaders would tell me that I have to show a bunch of extra documents before I can vote," Brown told the ACLU. "As a military veteran who fought to protect our democracy, it's particularly offensive."
