The State of Iowa has found an unlikely ally in its quest to block the Ponca Tribe from opening a casino in Carter Lake.

According to Omaha World-Herald, the state of Nebraska has joined Iowa in its federal lawsuit seeking to stop the development of a casino on five acres of land in Carter Lake, which is owned by the Ponca Tribe.

Nebraska named the National Indian Gaming Commission and the U.S. Department of the Interior, which administers the Bureau of Indian Affairs, as its defendants.

The two states have different reasons why they wanted to stop the Ponca Tribe from constructing a casino. Nebraska, where casino gambling remains illegal, fears that the opening of Ponca casino will result in the rise of problem gamblers in its own backyard. Iowa, on the other hand, is concerned that the opening of the tribal casino will result in less tax revenue collection from non-Indian gambling outlets in the state.
