LONDON (AP) — The parents of a terminally-ill baby boy lost the final stage of their legal battle to take him out of a British hospital to receive treatment in the U.S., after a European court agreed with previous rulings that the baby should be taken off life support. [...] the France-based European Court of Human Rights declined to hear the case Tuesday, instead endorsing earlier rulings by three British courts that found further treatment would cause the baby "significant harm" if his suffering is prolonged.
