When Kevin Logan went to his high school prom in 2006, he was hoping it would be a night to remember. What he'll remember, though, will be standing outside in the parking lot while his classmates danced inside.

As Logan walked up to the prom, clad in a pink prom dress, West Side High School Principal Diana Rouse blocked the doorway and refused to let him inside.

Logan, who goes by the name "K.K." and describes himself as a gay bisexual male, filed a suit Dec. 12 against Rouse and the school board, claiming they violated his civil rights by denying him entrance to the prom based on his attire.

"What should have been a once-in-a-lifetime opportunity for Logan to share memories with friends before graduation became an episode of humiliation and exclusion," the suit states.

When contacted by phone, Rouse declined to speak, referring comment to the school board public information spokesperson before hanging up. The school board declined to comment because of the pending litigation.
