A federal judge heard arguments Tuesday about whether Arkansas’ Issue 2 should be put on hold.

Cherokee Nation Entertainment filed a lawsuit against the State of Arkansas after voters approved a ballot measure that stopped the group’s planned casino. Cherokee Nation had planned to build a casino near Russellville in Pope County and had been granted a license.

But on Tuesday, Arkansas voters approved Issue 2 by a vote of about 56% to 44%. Issue 2 amends the state constitution and removes the Cherokee Nation’s license.
