Thank you Brodies for flagging  CSOH 25 George Docherty et al a while ago – I was not sure whether I might use the case for exam purposes. C-350/14 Lazar was among the precedents cited by Lord Tyre to decide the application ratione temporis of the Rome II Regulation.
Article 31 Rome II states that the Regulation applies to “events giving rise to damage which occur after its entry into force”. The date of entry into force, according to article 32, was 11 January 2009. The reference in article 31 to “events giving rise to damage” is not necessarily easy to determine. Lord Tyre at 31 clarifies things by suggesting the Article is ‘clearly linked to the distinction drawn in article 4(1) between three separate concepts, namely (i) the event giving rise to the damage; (ii) the damage; and (iii) the indirect consequences of the event. In the present case, the damage consisted of the deceased’s illness and death. The indirect consequences are the losses suffered by the deceased’s relatives. The event giving rise to all of this was exposure to asbestos’: this occurred before the entry into force of the Regulation.
Had it occurred after, the Court would have applied Rome II for the UK has opted to apply the Regulation’s Article 25(2) provision for Member States with internal conflicts of laws, to apply the Regulation to these conflicts: The Law Applicable to Non-Contractual Obligations (Scotland) Regulations 2008 (SI 2008/404) provide (reg 3) that the Regulation shall apply in the case of conflicts between the laws of different parts of the UK as it applies in the case of conflicts between the laws of other countries. SI 2008/2986 contains an equivalent provision for England, Wales and Northern Ireland.
Accordingly what the applicable law would be under the Regulation is not addressed, neither is the pursuers’ submission that any choice of English law by virtue of article 4(1) should be displaced by applying article 4(3) and holding that the delict is manifestly more closely connected with Scotland.
Residual conflict of laws applies and at 17 ff the judge applies pre-1995 common law, leading to the lex loci delicti. However these rules do not provide a clear identification of the lex loci delicti where the harmful event occurs in one jurisdiction (Scotland) but the harm, consisting of physical injury, occurs in another (England). Reviewing authority, Lord Tyre eventually holds (at 23) that the presence of asbestos dust in an employee’s lungs does not of itself constitute injury, and (subject to the Scottish statutory provisions regarding pleural plaques) no cause of action arising out of negligent exposure arises until it does. At 24: since injury is an essential ingredient of an actionable wrong, and since injury obviously cannot take place until after the breach of duty has occurred, the place of the harmful event (or locus delicti) is where the injury takes place and not, if different, where the antecedent negligent act or omission occurred.
Conclusion: lex causae is English law. The case is a good illustration of the difficulties that remain in applying what seem prima facie fairly understandable concepts to the average lawyer.
