The appeal of Paul Chambers, who joked about blowing up Robin Hood Airport two-and-a-half-years ago, will be heard today (Weds) by the most senior Judge in England and Wales. After the tweet, referring to snow causing flight cancellations, was spotted by a member of staff at the airport, Chambers was arrested and convicted by a district judge at Doncaster magistrates court in May 2010. He was fined £1,000 on a charge of "sending a public electronic message that was grossly offensive or of an indecent, obscene or menacing character contrary to the Communications Act 2003". An appeal at the high court in September 2010 failed and a subsequent appeal in front of two high court judges in February 2012 ended inconclusively when the court took the unusual step of ordering the appeal to be rerun. Celebrities, especially comedians, including Al Murray and Stephen Fry, have spoken out in support of Paul Chambers and of common sense. Indeed many people have expressed their concern over the conviction of Chambers, arguing that the tweet was obviously a joke, and something that we all do everyday.
