Kansas Gov. Sam Brownback has signed a measure blocking the use of Islamic law in the state.
The new law doesn't specifically mention Sharia law, but it does bar Kansas courts and government agencies from basing decisions on Islamic or other foreign legal codes.
Muslim groups oppose the measure, arguing it promotes discrimination. They say state bans could nullify wills or legal contracts between Muslims.
Supporters say the move will reassure Kansas residents that courts will rely only on the laws of that state and the U.S. They cited divorce and property cases around the country where judges or state agencies took Islamic law into account in their rulings.
The Council on American-Islamic Relations says the new law is discriminatory and a court challenge is likely.
