BILLINGS, Mont. (AP) - Wyoming’s Northern Arapaho Tribe has sued the leaders of the Eastern Shoshone Tribe, escalating a long-running political dispute between two American Indian tribes that share the Wind River reservation.
The lawsuit was filed Monday in U.S. District Court in Montana. It claims Eastern Shoshone leaders improperly approved mineral leases and made hiring decisions without consulting the Northern Arapaho.
Also named as defendants were representatives of the U.S. Bureau of Indian Affairs.
Tribal and federal officials say the reservation near Lander is home to more than 4,000 Shoshone and 10,000 Arapaho.
The suit comes after the Arapaho two years ago dissolved a joint council with the Shoshone, saying it created barriers to economic development and often wasted time.
