The Moors murderer, Myra Hindley, failed yesterday in her House of Lords bid for release from prison. But her lawyers immediately declared her intention to take her case to the European Court.The announcement came within minutes of five law lords ruling unanimously that the decision by the Home Secretary that her life sentence "must mean life" was both lawful and justified in view of her "exceptionally wicked and uniquely evil" crimes.Hindley (57) was convicted in May 1966 for helping her lover, Ian Brady, murder Lesley Ann Downey (10) and Edward Evans (17).Lord Steyn said: "There is nothing logically inconsistent with the concept of a tariff by saying that there are cases where the crimes are so wicked that even if the prisoner is detained until he or she dies it will notexhaust the requirements of retribution and deterrence." Britain's highest court ruled the Home Secretary was entitled to impose "whole life" tariffs provided they were kept under review.
