WASHINGTON (AP) - A split Supreme Court struck down Ten Commandments displays in courthouses Monday, ruling that two exhibits in Kentucky cross the line between separation of church and state because they promote a religious message.

The 5-4 decision was the first of two seeking to mediate the bitter culture war over religion's place in public life. In it, the court declined to prohibit all displays in court buildings or on government property. Justices left legal wiggle room, saying that some displays - like their own courtroom frieze - would be permissible if they're portrayed neutrally in order to honor the nation's legal history.

But framed copies in two Kentucky courthouses went too far in endorsing religion, the court held.

"The touchstone for our analysis is the principle that the First Amendment mandates government neutrality between religion and religion, and between religion and nonreligion," Justice David H. Souter wrote for the majority.

"When the government acts with the ostensible and predominant purpose of advancing religion, it violates tha central Establishment clause value of official religious neutrality," he said.
