Infringement of personality rights, including invasion of privacy, is exempt from the Rome II Regulation on applicable law for non-contractual relations. TLT at the High Court shows how distinct national laws may look upon the issue of quantification of damages very differently. Robin Hopkins reviews precedent and the case itself here, and One Crown Office Row zoom in on the case itself here. This case did not involve conflict of laws, however I thought I would highlight it anyway, for it is common knowledge that national laws assess damages in cases like these very differently.
It is worth pointing out in this respect that infringement of personality rights is exempt from Rome II not because it is irrelevant. Rather the contrary: it is very relevant indeed and no agreement could be found on an applicable law rule.
