EMI is suing Ireland. The country.
As reported by the Toronto Standard the record label have filed a lawsuit following Ireland’s non-compliance with European Law regarding the blocking of internet service providers that are known to breach copyright law.
It is speculated that the lawsuit will aim to exploit the lack of Irish law when it comes to illegal filesharing and establish a link between that and the pirating of music by EMI acts such as Snoop Dogg and KT Tunstall.
Also it's a really good way to get punters on side re the whole 'people vs the labels' business. Suing a country! Brilliant.
