Lucy Rigby

Lucy specialises in competition litigation and has particular expertise in large-scale collective redress.  


Lucy started her career in the competition group at Slaughter and May, following which she moved to the Office of Fair Trading (now the Competition and Markets Authority) and then to Which?, where she advised on competition and consumer law matters. Lucy joined Hausfeld in 2017 and her expertise has proven invaluable in its filing of two opt-out collective actions under the UK’s class actions regime introduced by the Consumer Rights Act 2015. 

Lucy has extensive experience of conducting litigation before the Competition Appeal Tribunal, the High Court and the Court of Appeal.  She has also worked on European and domestic antitrust investigations for public and private companies, as well as for the regulator, and has experience of working on high-profile merger transactions. She has also appeared before the House of Lords EU Committee to give oral evidence on aspects of consumer law.


Lucy has worked on numerous pieces of highly complex, multi-jurisdictional litigation across a variety of sectors. Notable representations at Hausfeld include acting on behalf of 100+ corporate groups against British Airways in the Air Cargo litigation and for proposed class representative Justin Gutmann against train operating companies in the first standalone class actions to be filed in the UK.  

Passionate about achieving justice, including for those who cannot afford legal representation, Lucy has been involved in the running of a number of community law centres.  

Practice Areas

Competition Disputes

Lucy has played a key role in some of Hausfeld’s highest-profile competition litigation cases:

  • Trains: The first standalone opt-out collective actions to be filed in the UK. Hausfeld filed  claims on behalf of millions of rail passengers in the Competition Appeal Tribunal against the operators of the South Western and Southeastern rail franchises. The opt-out, collective action is being led by proposed class representative Justin Gutmann, an experienced campaigner on consumer issues.
  • Air Cargo: Hausfeld pursued claims in the High Court for losses that occurred in over 50 different jurisdictions on behalf of 100+ corporate groups against British Airways in relation to the worldwide Air Cargo cartel in air freight surcharges - one of the largest and lengthiest competition damages action brought in Europe to date. The claim settled after a complex 6-month mediation process in December 2018.
