Washington, D.C.’s federal court has set a three-judge court to preside over a challenge to President Donald Trump’s recent executive action meant to exclude undocumented immigrants from the total census count used for congressional seats.

In an order Tuesday, Chief Judge Sri Srinivasan of the U.S. Court of Appeals for the D.C. Circuit said U.S. District Judge Christopher “Casey” Cooper—who was originally assigned to the case—will be joined by U.S. District Judge Dabney Friedrich and Judge Gregory Katsas of the D.C. Circuit in deciding the case. Katsas will preside over the matter, according to Srinivasan’s order.
