A suburban Louisville police department improperly fired a police sergeant after he complained about derogatory statements made by his supervisor about his being gay, the Louisville Metro Human Relations Commission said in finding presented to attorneys.Former Audubon Park Police Sgt. Kile Nave claims that his supervisor, Ronald W. Jones, repeatedly made disparaging remarks about Nave's sexual orientation from the time he joined Audubon Park Police in 2009 to his firing in August 2012. Nave also filed a lawsuit against Audubon Park, Jones and others in Jefferson Circuit Court. At the conclusion of the Human Relations process (which also includes hearing before a hearing officer from the state Administrative Office of the Court), the city could be ordered to hire back Nave or pay damages,according to state statute.In July 2012, Nave claims, Jones unleashed a "barrage of profanity-laced rants" at him. Nave complained to then-Chief Jeffery Cox—soon after, he was placed on a different shift and eventually accused of violating 57 department rules and fired.Audubon Park denies that its officials discriminated or retaliated against Nave, said Kyle Vaughn, an attorney for the city. Vaughn described the Human Relations Commission ruling as preliminary. For his part, Nave said he'd never been disciplined in more than 20 years of police work and that colleagues in the Audubon Park Police Department vouched for his work.“It was all due to the fact that I was cussed at and I asked Mr. Jones to stop using certain profanity in my presence," Nave said on Wednesday.Jones couldn't be reached for comment. Nave's lawsuit notes that Jones said during a hearing that he didn't recall making harassing comments about or in front of the sergeant.He and Cox no longer work for Audubon Park Police.The Human Rights Commission's probable cause finding stems from Metro Louisville's ordinance making it "unlawful practice for an employer to discriminate against and harass any individual because of such individual's sex and sexual orientation and in retaliation for filing a complaint with the (sic) his employer alleging such discrimination. "In its letter, the Human Relations Commission said:
