A superior court judge in Seattle ordered the Northwest chapter of the American Lung Association to stop using the word “lung” in its name and stop using donor lists belonging to the national organization, reports the Associated Press.

The national organization says the chapter breached its contract because it gave its Seattle headquarters building, and $600,000, to a different, new charity, the news agency reports. Mike Alderson, chief executive of the organization, said the new charity was created to do high-caliber fund raising to benefit his chapter and other lung-health-related organizations, the AP reports.

The dispute may be resolved in mediation, which was ordered by the judge, but a trial date has been set for June in case that fails.
