Howard said then that the club has the right to hang it in either school.
The portrait now is hanging on a wall alongside a trophy case, but the amended lawsuit filed in federal court in Columbus says the moving of the portrait to the high school and creation of the "limited public forum" policy is "nothing more than a contrived pretext to conceal" school officials' continued involvement with the maintenance and display of the portrait.
ACLU of Ohio spokesman Nick Worner said last month after the portrait was moved that the group's position hadn't changed.
"It doesn't matter which public building the portrait is in," Worner said then. "It's an unconstitutional endorsement of religion on the part of a public school."
Worner did not immediately return calls to the ACLU's Cleveland headquarters on Monday.
