A man who was convicted and fined for a Twitter message threatening to blow up an airport has said he will take his case to the High Court.

Paul Chambers was convicted in May for sending a menacing electronic communication.

A recent appeal failed to overturn the conviction, sparking outrage amongst Twitter users.

The 27-year-old accountant will now be represented by high-profile human rights lawyer Ben Emmerson.

The challenge will centre on whether or not section 127 of the Communications Act , under which he was convicted, was "appropriately applied".

Mr Chambers and his lawyers have until 2 December to challenge the conviction.

His lawyers regard Mr Chambers' conviction as a test case, as it was the first time that the Communications Act was applied to an offence on a social network.

"We want to establish what constitutes a menacing communication, what should be the level of intent required for the offence to be committed, and whether or not Paul's message was sent by means of a public electronic communications network," said David Allen Green, his solicitor.

Doncaster Crown Court recently upheld his original conviction causing a wave of outrage on Twitter, with thousands of supporters retweeting Chambers' message, which read: "Crap! Robin Hood airport is closed. You've got a week to get your shit together, otherwise I'm blowing the airport sky high!"
