Dr Mahtani, who had sold FBZ to Atlas Mara, brought claims that Atlas Mara had, in breach of contract, unreasonably opposed his appointment of a fund raising agent as a result of which he had not received valuable earn outs, and wrongfully refused Dr Mahtani’s bid to reacquire one of FBZ’s subsidiaries. Leading Richard Mott at a trial including multiple expert witnesses, Anna’s team won on liability and quantum issues, and her client was awarded a substantial portion of its costs on the indemnity basis.
      • Eurasian Natural Resources Corporation v Serious Fraud Office, John Gibson and Antony Puddick
        Acted for ENRC in high profile Commercial Court claims in misfeasance in public office and breach of confidence. ENRC alleged that the SFO and its officers had leaked information about the SFO’s decade long investigation into the company. One SFO officer had a meeting with a journalist in an underground car park; another appeared to be identified as an SFO source in emails to and from an individual who traded in confidential information. Anna was the advocate at a series of substantial procedural hearings, obtaining orders in relation to the interrogation of SFO custodians’ personal devices and the revision of redactions for irrelevance which had been applied by the SFO on inappropriate grounds. Anna led David Glen and Helen Morton in preparing for the 7-week trial, in which her team had eighteen witnesses of fact to cross examine. The claims were settled at the start of trial.
      • Inspired Education Online Limited v Tom Crombie
        Acting for Mr Crombie, a former teacher and entrepreneur who set up an online school in 2017 and sold it in 2022 to Inspired, owner of another UK online school.

The students also bring claims for non-provision of teaching during industrial action. UCL denies that it promised in person teaching at all, and relies on variation and force majeure clauses which are, on the students’ case, unfair under the Consumer Rights Act 2015. The claims raise novel issues and, if successful, may lead the way to similar claims by thousands of students at other universities. Anna leads Alyssa Stansbury. A trial of ten test cases will be determined in the Kings Bench Division at a four week trial in 2026

Anna was part of a team of nine counsel, led by Clare Montgomery KC.  Anna was the advocate in most of the interlocutory hearings in the claim against Dechert (including multiple disclosure and security for costs applications) and conducted cross examination of two Dechert partners and various SFO witnesses at trial.

Anna led Emma Jones and was the advocate in a number of hearings for Telefonica before the dispute was settled.
         
      • City East Recruitment v British Gas
