SIOUX CITY, Iowa (AP) – Legal issues remain unresolved following the Iowa Supreme Court’s decision not to rule on the closure of the former Argosy Sioux City riverboat casino. Last week the high court rejected the Belle of Sioux City’s request to review an Iowa Appeals Court decision that upheld previous rulings leading to the casino closure.

The Sioux City Journal reports that among the legal issues still pending is a breach of contract lawsuit Penn National Gaming Co. filed against Missouri River Historical Development, the state-licensed nonprofit gambling group that had held Woodbury County’s gambling license with the Belle of Sioux City, a subsidiary of Penn National.

There’s also the matter of nearly $1.8 million in revenue-sharing payments the Argosy owner withheld from the gambling group during the last year the casino operated.
