Join us on the 1st October at The Bristol Marriott Royal for the Guildhall Chambers Annual Commercial Seminar.

Following the success of last year’s event, the seminar this year will consist of a mix between plenary sessions covering topics of general interest to all commercial litigators and then more specialist “Masterclasses” focusing on either corporate and commercial law or professional negligence.

Choose the sessions that suit you best and gain insights from leading experts in the following fields.

Masterclass topics

Professional negligence

  • Attribution of loss and scope of duty as summary judgment issues in professional negligence claims. 
    • What are the lessons to be learned from Afan Valley Ltd (in admin) and Ors v Lupton Fawcett LLP [2026] EWCA Civ 2? The speaker for this topic will be Nick Evans.

    • In what circumstances can limitation time limits in professional negligence actions be extended under s.14A Limitation Act 1980 after the Court of Appeal’s decision in Kay v Martineau Johnson [2026] EWCA Civ 224? The speaker for this topic will be Holly Doyle

Company/Commercial

  • Case law update.
    • Christopher Hare and Jakub Kaluza will outline some of the significant recent decisions in 2025 and 2026 of which commercial practitioners should be aware and distil the practical lessons to be learned from these decisions.
  • ADR Masterclass.
    • Hugh Sims KC and Jack Brett joined by Geoff Mesher will lead a more informal session on how to (and how not to) prepare for and participation in various forms of ADR, including expert determination, mediation and arbitration.
