A Memphis high school is accused of violating the privacy of two male students by publicly identifying them as homosexual.

In a letter to the Memphis school board, which was made public Tuesday, the American Civil Liberties Union said the teenagers were identified as a gay couple on a list of students compiled by the staff at Hollis F. Price Middle College High School.

The list identified dating students as part of attempts to limit public displays of affection on campus and was kept in the principal's office, the ACLU said.

The ACLU, threatening legal action, asked the board to ban the public exposure of such private information about students.

Van Davis Turner Jr., associate general counsel for the Memphis City Schools Board of Education, said the matter is being taken seriously.

"At this time, we have not completed our internal investigation of this matter. Once we have, we will submit a formal response to the ACLU, directly addressing the issue. We look forward to working with the ACLU to amicably resolve this matter, if possible."
