As pointed out over at the Conflict of Laws Blog, the Rome I Regulation has been published. Its more technical appellation is Regulation EC N° 593/2008 of the European Parliament and of the Council of June 17th 2008 on the law applicable to contractual obligations (Rome I).
It will apply to contracts concluded after December 17th 2009. The Regulation will apply in Ireland. On the other hand it will not apply in Denmark and does not, at present, apply in the United Kingdom.
The Rome I is a major piece of legislation and replaces the Rome Convention.
