The International Longshore and Warehouse Union says it intends to appeal a judge’s ruling that threw out their lawsuit aimed at undoing a deal to build a new professional basketball and hockey arena in Seattle - a key part of plans to bring the NBA back to town.

The ILWU says it will announce appeal plans during a news conference on Tuesday. The ILWU Local 19, representing workers at the Port of Seattle, says they believe the court failed to acknowledge that the memorandum of understanding between investor Chris Hansen, the city of Seattle and King County is in violation of the state environmental protection act.
