The Northwest chapter of the American Lung Association said on Monday that it would fight the national charity’s efforts to dissolve it over a real-estate sale and other disputes, reports the Associated Press.

“This is the kind of a dispute between two charitable nonprofits that should have been settled in the family,” Laird Harris, chairman-elect of the Northwest affiliate’s board, said in a written statement. “ [The American Lung Association’s] aggressive and destructive decision to pursue the matter in court and in the media is damaging to our common mission of promoting lung health.”
