On 19 October 2021, the CAT published its judgment on the strike-out and collective proceedings order (CPO) applications in the claims brought by Mr. Justin Gutmann alleging abuse of dominance by London & South Eastern Railway Limited, First MTR South Western Trains Limited, and Stagecoach South Western Trains Limited. The claims relate to “boundary fares,” which are a type of extension or add-on fare sold for use in conjunction with a Transport for London Travelcard. Mr. Gutmann alleges that the train companies failed to make boundary fares sufficiently available and/or failed to use their best endeavours to ensure awareness of boundary fares among consumers so they could avoid being double-charged for part of their journey. The strike-out application was dismissed and the CAT granted the applicants a CPO on the basis that the claims raised common issues (of dominance and abuse) that were suitable to be brought in collective proceedings. This is the first collective proceedings action to be brought on a standalone basis under s.47B of the Competition Act 1998.
