Opening another front in the battle over immigration policy, Texas and six other states sued the federal government on Tuesday in an attempt to end the Deferred Action for Childhood Arrivals program.

The lawsuit — joined by Alabama, Arkansas, Louisiana, Nebraska, South Carolina and West Virginia — asserts that the Obama administration overstepped its authority when it created the DACA program, which allows individuals who were brought to the United States illegally as children to remain in the country, without congressional approval.

“The executive unilaterally conferred lawful presence and work authorization on otherwise unlawfully present aliens, and then the executive used that lawful-presence ‘dispensation’ to unilaterally confer United States citizenship,” the lawsuit says.

It says the United States District Court for the Southern District of Texas has the authority to “immediately rescind and cancel all DACA permits currently in existence because they are unlawful,” and asks it to block the government “from issuing or renewing DACA permits in the future, effectively phasing out the program within two years.”
