WICHITA, Kan. (AP) — A federal court clerk has entered a default judgment against Kansas Secretary of State Kris Kobach for failing to file a timely response to a lawsuit challenging the constitutionality of a state law requiring prospective voters to prove they are U.S. citizens.

It remains unclear whether U.S. District Judge Julie Robinson will give Kobach more time to respond. Kobach is facing four separate lawsuits challenging aspects of that law.

If Tuesday’s judgment stands it would entirely strike down the state’s proof-of-citizenship requirement. The lawsuit contends it violates the U.S. Constitution’s protections against depriving a person of life, liberty or property without due process.

It also contends the state law discriminates against citizens born outside of Kansas.
