  • Alex Neill Class Representative v Sony: Acting for Sony in its defence of collective proceedings brought by a proposed class representative concerning alleged abuse of dominant position in respect of Sony’s operation of the PlayStation Store said to have caused losses in the region of £5 billion (with Daniel Beard KC); one of the first cases to consider the effects of the PACCAR judgment
  • Advising Microsoft in respect of its proposed $70 billion merger with Activision Blizzard, which the CMA initially sought to block (with Lord Anderson KC)
  • Acting for the Kingdom of Sweden in its civil fraud claim in respect of €120m frauds perpetrated against the Swedish Pensions Agency in Sweden and Malta (reported at The Kingdom of Sweden v Serwin [2022] EWHC 2706 (Comm.); [2020] EWHC 1251 (Comm)) (with Richard Eschwege KC)

Reported cases frequently pay tribute to the quality of her written and oral advocacy – for example, “very well argued on both sides”, in a Court of Appeal case concerning unjust enrichment of overpaid tax ([2019] EWCA Civ 972); “persuasive oral submissions” ([2018] EWHC 2297 (QB)); “clear and helpful” skeleton and “clear and focused” oral submissions ([2016] EWCA Civ 1047).

Charlotte read law at Cambridge University, then completed the LLM at Harvard Law School and the BCL at Oxford University, receiving numerous exam prizes for topping the year in her subjects at each institution. She was the 2013 Eldon Law Scholar (a substantial monetary prize awarded annually to the most promising Oxford graduate going to the Bar).

Before commencing practice, she worked as a stagiaire at Shearman & Sterling’s International Arbitration Group in Paris; taught contract law at UCL and KCL; and was Judicial Assistant to Lord Clarke and Lord Sumption at the Supreme Court.

Charlotte is fluent in French and German and has a working knowledge of Spanish. She enjoys learning languages for fun, with recent focus on Italian and Serbian/Croatian, and is often able to deploy her language knowledge in her cases.
