In February 2015, the ECHR upheld the lawfulness of whole life orders, on the ground that they can be reviewed in exceptional circumstances, following a fresh challenge by murderer Arthur Hutchinson, who had been sentenced to life imprisonment for a triple murder in Sheffield more than 30 years earlier. Another legal challenge to the court by Hutchinson was rejected in January 2017. By this stage, there were believed to be more than 70 prisoners in England and Wales serving whole life sentences.
