The Supreme Court has rejected an appeal to review a Florida law that requires public school students to recite the Pledge of Allegiance each day unless they have their parents' written permission excusing them.

The justices declined Monday an appeal filed by the American Civil Liberties Union of Florida on behalf of a high school student removed from his math class because he remained seated during the pledge.

A federal appeals court upheld most of the law. The ACLU said that ruling, if left undisturbed, would undermine the Supreme Court's 1943 ruling that schoolchildren could not be forced to salute the flag and say the pledge.

Florida argued that the law, by giving parents the right to have their children excused, does not violate the First Amendment.
