NEW ORLEANS (AP) — A divided Louisiana Supreme Court has overturned a $330 million judgment against two pharmaceutical companies that state Attorney General James “Buddy” Caldwell accused of improperly marketing a drug.

The state’s highest court ruled Tuesday that Caldwell’s office failed to prove that Janssen Pharmaceutica Inc. or Johnson & Johnson Inc. violated a state law by misrepresenting the potential risk of side effects from the use of Risperdal, an anti-psychotic drug.
