WASHINGTON (AP) — The Supreme Court ruled narrowly Tuesday in favor of a government policy that threatens broadcasters with fines over the use of even a single curse word on live television, yet stopped short of deciding whether the policy violates the Constitution.

In six separate opinions totalling 68 pages, the justices signaled serious concerns about the constitutionality of the Federal Communications Commission's "fleeting expletives" policy, but called on a federal appeals court to weigh whether it violates First Amendment guarantees of free speech.
