A fundamentalist Christian leader on Tuesday sought to have Britain's High Court overturn a lower-court order tossing out his lawsuit against the BBC and the producers of Jerry Springer, which air on the publicly supported network in 2005. Stephen Green of the group Christian Voice called the production blasphemous and therefore unlawful under British law. But civil liberties groups filed briefs with the court contending that Britain's blasphemy law is outdated and violates the European Convention on Human Rights, to which the country is a signatory. Anna Fairclough, legal officer of the group Liberty, said in a filing, "These blasphemy laws should be shelved in dusty archives, not used as a tool to bring mischievous prosecutions against the arts."
