( CNN ) -- A landlord wants the Ohio Civil Rights Commission on Thursday to reconsider its finding that she violated the law by posting a `` white only '' sign at her swimming pool . Jamie Hein has asked the commission to reverse its initial ruling that found she violated the Ohio Civil Rights Act by putting up a sign that read `` Public Swimming Pool , White Only '' at her Cincinnati duplex . The commission , meeting this week in Columbus , concluded last year that the sign `` restricts the social contact between Caucasians and African Americans as well as reinforcing discrimination actions that are aimed at oppressing all 'people of color . ' '' The case was brought by Michael Gunn , a white man who said had unrestricted access to the pool area for himself and his guests during the nearly two years he lived in the duplex , he said in a December interview . Gunn , a software engineer , said he and his girlfriend , who is also white , lived upstairs ; their 31-year-old landlord lived downstairs . However , he said their relationship soured in May 2011 when he invited his 10-year-old biracial daughter to visit and swim in the pool . `` Complainant states that the owner , Jamie Hein , accused his daughter of making the pool 'cloudy ' because she used chemicals in her hair , '' the commission said in its summary . `` Days later , the owner posted a sign on the gate to the pool which read , 'Public Swimming Pool , White Only . ' '' Hein said she received the sign from a friend and posted it in early May , the summary says . Several people interviewed by the commission staff confirmed that they had seen the sign , it added . Hein did not respond to a request for comment at the time . But she told ABC News in December that she collects antiques . She said the sign , which was dated 1931 and from Alabama , was a gift from a friend . `` I do n't have any problem with race at all . It 's a historical sign , '' she told ABC . Gunn said he was outraged by the sign and made arrangements to find another place to live as soon as he could . `` We were extremely upset and moved out on June 21 , 2011 , in order to not expose my daughter to the sign and the humiliation of the message , '' Gunn wrote in his complaint . He said he never confronted Hein about the matter , but has no doubt that the sign was intended for his daughter .
Jamie Hein is asking the state civil rights commission to reconsider its ruling . The commission has previously ruled Hein violated the Ohio Civil Rights Act . A federal judge in Cincinnati on Friday dismissed a lawsuit filed by Hein, who was fired from his job as an assistant principal at East High School after he refused to allow students of different races into A former tenant says the sign was put up after his biracial daughter swam in the pool .
