Question to the Department for Business and Trade:

To ask His Majesty's Government what assessment they have made of the impact that introducing legislation to reverse the effect of R (on the application of PACCAR Inc and others) v Competition Appeal Tribunal and others [2023] UKSC 28 will have on the review into the opt-out collective actions regime.

As announced on 17 December 2025, the Government intends to implement recommendations made by the Civil Justice Council to mitigate the effects of the PACCAR judgment, alongside proportionate regulation of litigation funding to improve transparency and fairness for all.

The review of opt-out collective actions is focused on finding the right balance between preserving an important route to redress for those harmed by anti-competitive behaviour and ensuring that the burden on business is proportionate. Work on litigation funding is distinct from the review, but will complement it and is expected to support the smooth operating of the regime.
