So there's no reason why this shouldn't work.  Click submit and I'm diverted to this page:

The use of Twitter to promote cases you're working on may be the best use of Twitter yet.  #TwitterJokeTrial being the most obvious, but also the representation of Sally Bercow in 2010 gave useful insights into how libel works, allowing us lay people to gain a better understanding of how law operates in the UK.

In those cases (again #TwitterJokeTrial springs immediately to mind), it leads to morale-boosting support of the people you're representing, and even a successful funding campaign to keep the case going.  It's a really powerful tool.
