An eight-member Supreme Court quizzed both sides Monday in an Arizona case that asks whether small government agencies should be exempt from age discrimination laws, just as small businesses are. A lower court said they should not, that a government agency of any size should be subject to the law – a ruling that would be “financially crippling” for cash-strapped agencies if allowed to stand, said one advocate challenging the ruling. The case began in 2009, when the Mount Lemmon Fire District laid off Capts. John Guido and Dennis Rankin, who happened to be the two oldest firefighters in the department at the time. They filed a claim with the Equal Employment Opportunity Commission, citing the Age Discrimination in Employment Act.
