A man who joked on Twitter that he would blow up a British airport after it closed because of snow has had his conviction for sending the supposedly menacing message overturned.
It is being lauded as a landmark ruling for users of social media around the world.
Paul Chambers sent the message in what he called a moment of frustration at not being able to catch a flight from Doncaster Robin Hood airport.
He was arrested and sentenced but a court in England upheld his appeal against conviction.
Mr Chambers' barrister John Cooper, who had argued it was wrong to associate the tweet with terrorism, said it was a milestone ruling.
He said the decision means that if someone makes a joke, no matter how bad it is, they cannot be prosecuted.
