The author of the strict Arizona immigration law that was mostly shot down by the Supreme Court this summer has filed a lawsuit on behalf of 10 immigration officials against the Obama administration for its recently revamped deferred-deportation policy.

Kansas Secretary of State and immigration hardliner Kris Kobach filed the lawsuit on Thursday against Homeland Security (DHS) Secretary Janet Napolitano and Immigration and Customs Enforcement (ICE) Director John Morton on behalf of 10 ICE officials, including the head of the immigration agency’s labor union, Chris Crane.

The suit was filed in the District Court for the Northern District of Texas and challenges a new policy announced by Napolitano earlier this year by arguing that it forces officers to break the law.
