Microsoft -v- USA is an important ongoing case, currently listed for hearing in 2015 before the US Federal Court of Appeal of the 2nd Circuit.
You can read about why this case is significant for Microsoft on their official blog.
However, as the case centres around the means by which NY law enforcement are seeking to access data of an email account which resides in Dublin, it is also crucially significant to Ireland and the rest of the EU. For that reason, Digital Rights Ireland instructed us to file an Amicus Brief in the US case, in conjunction with the global law firm of White & Case, who have acted pro bono in their representation.
Given the significance of the case for the wider EU, both Liberty and the Open Rights Group in the UK have joined Digital Rights Ireland as amici on this brief. We hope it will be of aid to the US court in assessing the significance of the order being appealed by Microsoft for EU citizens and European states, in the light of the existing US and EU Mutual Legal Assistance Treaty.
