Significant Experience

  • She also advised NHS England on the publication of the new NHS tariff and on the Improving Access to Psychological Therapies programme.
  • Her involvement in a complex shareholder dispute which originated as an intellectual property dispute and involves three unfair prejudice petitions, a debt claim, counterclaim, Part 20 claim and an appeal is nearing a close after nearly three years.  The Petition against the clients was dismissed at trial and settlement was subsequently negotiated in relation to their successful counterclaim and Cross Petition, representing an excellent outcome for the clients overall.  She has significant experience of advising clients in the care, aviation and renewable energy industries, in relation to shareholder and other corporate disputes and avoiding issues arising as a result of corporate restructuring exercises.

  • Early on in her career she was successful in taking an injunction application to the Court of Appeal on behalf of a national Plc concerning a Post-Completion Dispute and has recently assisted in the recovery of £1.9 million owed to clients as Deferred Consideration following the sale of their company to a multi-national, pursuing the contractual expert determination procedure.
  • She has also dealt with a number of professional negligence claims on behalf of companies against their former legal advisors and financial advisors, successfully recovering damages from the insurers.
  • Joanna is also assisting on the procedural aspects of a multi-disciplinary claim for declarations from the High Court of the rent to be paid for a significant redevelopment site.  The sums involved amount to tens of millions and the calculation of the rent is in dispute.
