This decision, alongside other recent decisions such as Gemalto v Infineon, forms a trend of judicial reluctance to extend limitation periods in competition damages litigation beyond the scope of the existing English law of limitation. It should be noted that both this decision and Gemalto are only of relevance to damages actions in relation to competition infringements that ceased prior to 9 March 2017. After this date, Schedule 8A of the Competition Act 1998 – which implements the Damages Directive – applies and limitation periods will be suspended during an investigation by a competition authority. These decisions, therefore, apply only to the "legacy" claims currently making their way through the courts. However, there is a substantial body of such claims, and these recent decisions indicate that the courts will not assist claimants who have delayed in bringing their claims by bridging the gap between the existing law of limitation and the new provisions of Schedule 8A. Should the CJEU follow the opinion of AG Kokott in Heureka v Google, this decision will also represent a clear fork in the road between the UK and EU's approach to limitation in these legacy claims.
This decision is also of wider significance in that it dismisses any notion of "accrued EU law rights" which would develop separately with EU law, creating a schism of applicable law where claims under EU law arose but were not asserted prior to IP Completion Day. The CAT held that the litigation of claims arising under provisions of EU law, including those claims accruing and asserted before IP Completion Day, must reflect the reality of the UK's transition from a member state to a third country.
Finally, the decision is a noteworthy early example of where the English courts may be prepared to diverge from EU case law developments post-Brexit. Based on this decision, it appears that such a divergence may be more likely where EU law decisions represent a marked change to an already well-established position taken by the English courts, as opposed to, for example, a gradual development of the existing position.
