Here's an interesting one - not that music related, but interesting. The Sun has escaped prosecution over allegations they illegally named the victim of a sexual assault because the Crown Prosecution Service launched proceedings against the wrong company.
The CPS launched litigation against News International, the parent company of the Sun. However, there is actually no legal entity called News International in the UK, and the company that actually publishes the paper is called News Group Newspapers.
On those grounds the courts said the CPS could not proceed with the case against the newspaper, and because the six month deadline has now passed for this kind of action they can't launch new litigation against the right company. Doh.
