In 2012, Baker McKenzie helped overturn Paul Chambers' conviction under the Communications Act of 2003 (the Twitter Joke Trial) for tweeting a "message of a menacing character." Chambers, an accountant, had tweeted a "silly joke" about "blowing up the Robin Hood airport in South Yorkshire." The team advising on his appeal was led by Preiskel & Co's David Allen Green, John Cooper QC of 25 Bedford Row and Sarah Przybylska of 2 Hare Court. The Baker McKenzie team, which acted on the case pro bono from 2010, included partners Harry Small, Tom Cassels and Ben Allgrove.
