DES MOINES, Iowa (AP) — Multiple parties in a legal fight over casino gambling in Sioux City are objecting to a group’s bid to join a lawsuit. Warrior Entertainment LLC recently filed requests to intervene in a lawsuit by Penn National Gaming Co.

Penn is challenging the Iowa Racing and Gaming Commission’s decision last year to award a casino license to the owners of the Hard Rock casino. Warrior Entertainment, a partnership involving Ho-Chunk Inc. and others, also lost a bid.

The Sioux City Journal reports the commission, the Hard Rock developer and Sioux City officials all object to Warrior Entertainment’s petition. The commission argued in a motion Monday that the group is trying to “piggyback” onto the lawsuit. Ho-Chunk President and CEO Lance Morgan says the group has an interest in the proceedings.
