“The famous ‘Twitter joke’ conviction of Paul Chambers has been overturned on appeal, bringing welcome clarity to what is and what is not an offence of this type. On discovering a week before he was due to take a flight that the airport was closed due to adverse weather conditions, he tweeted that ‘I am blowing the airport sky high!!’ unless the situation was resolved by the time of his flight. He was convicted of sending a message of a ‘menacing character’, but has had the conviction quashed on appeal, on the basis that, as it was a joke, it was not of a menacing character.”
