On 3 March 2011 the Crown Court upheld the conviction of Paul Chambers for sending by a public electronic communications network a message of a "menacing character" contrary to s.127(1)(a) and (3) of the Communications Act 2003.  Mr Chambers had been convicted after Tweeting:

"Crap!  Robin Hood Airport is closed.  You've got a week and a bit to get your shit together otherwise I am blowing your airport sky high!!"

The decision was overturned this morning on appeal.  The judgment can be found here.
