City of Hastings v. Sheets

Summary

The court held that the declaratory judgment action became moot when the viaduct was demolished during the litigation because neither party retained a legally cognizable interest in whether a referendum should be held. The court also held that the public interest exception to mootness did not apply because the circumstances were unlikely to recur and the case was unsuitable for authoritative guidance. It affirmed the district court in part, reversed in part, and remanded with directions to dismiss the action.
