Rome II

The Rome II Regulation, which was published on 31 July 2007 and applies to all EU Member States (except Denmark) introduces new rules apply, among others, to claims based on competition law. Rome II aims to harmonise the conflict of laws rules applied by Member States when dealing with disputes involving non-contractual obligations and means that one rule for choice of law in such disputes applies across all Member States.

In this context “non-contractual obligations” includes claims based on tort such as negligence, breach of competition law and breach of statutory duty.

But, brilliantly, it does not apply to non-contractual obligations arising under bills of exchange, cheques and promissory notes and other negotiable instruments which arise out of their negotiable character.

Rome II doesn't apply to company law defamation either. Though it's kind of hard to see how you could have a contractual obligation to defame someone.
