(AP) — Kansas is supporting Hobby Lobby in its fight to challenge the Affordable Care Act’s requirement that employers cover emergency contraceptives.

The Kansas Attorney General’s Office filed a brief with the U.S. Supreme Court in support of Hobby Lobby Inc., an Oklahoma-based arts and crafts retail chain. Hobby Lobby’s founder and CEO David Green objects to the regulation based on his religious principles.

Attorney General Derek Schmidt says in a statement that the issue is religious liberty. He says the Constitution protects businesses that want to base policies on religious teachings.

The Supreme Court is expected to argue the case in March, with a decision expected by summer.
