The Supreme Court said Monday it will consider an Arizona case that asks whether the Age Discrimination in Employment Act applies to government agencies with fewer than 20 employees. The case stems from the 2009 firing of Mount Lemmon Fire District Capts. John Guido and Dennis Rankin, who were the oldest employees in the department when the cuts were made for budget reasons. The district said that Guido, then 46, and Rankin, then 54, were terminated not because of their age, but because they had not participated in volunteer wildland assignments, fighting fires in areas of natural vegetation.
