Lottie (Charlotte) Mallin-Martin specialises in Chambers’ core practice areas of Commercial and Employment & Discrimination law.

Lottie is regularly instructed to appear in multi-day hearings before the Employment Tribunal, the County Court and the High Court. She has appeared unled the EAT and the High Court.

In July 2025, Lottie appeared as junior counsel (led by Hugh Sims KC, with Jay Jagasia) before the Supreme Court in Kession Capital Ltd v KVB Consultants Ltd & Others. The case is concerned with the scope of responsibility of authorised persons for the regulated activities of their appointed representatives under s.39 FSMA 2000.

Lottie is instructed alongside team members as junior counsel in complex, multi-million-pound disputes in the High Court and Employment Tribunal. She is often called upon to assist in cases where proceedings are running concurrently in the Tribunal and Civil Courts. Her cross-over specialisms include employee / shareholder competition and shareholder / partnership disputes.

Lottie is passionate about Pro Bono work. She is currently the Western Circuit’s Pro Bono representative and a member of Advocate, the Bristol Pro Bono Group and the Hampshire Pro Bono Group. In 2025, she received the John Collins Award at the Bar’s National Pro Bono Awards.

She has already been led by senior members of the Commercial Team in high value unfair prejudice petitions.

Lottie also has experience advising on, and assisting with, large-scale disclosure exercises in this type of litigation.

Lottie’s mixed commercial-employment practice makes her particularly well-suited to assist with business protection disputes.

Recent cases include:

  • Acting as sole counsel for a claimant IFA firm which pursued a claim against a former employee for soliciting the custom of c.50 customers. The defendant alleged that they had a ringfencing agreement in place following the move from their previous IFA firm. The claim settled shortly before a four-day High Court trial.
  • Defending (as sole counsel) an IFA against a claim for breach of their PTRs, misuse of confidential information, and retention of customer records under the Copyright and Database Regulations 1997.
  • Acting for a stormwater management company when it sought to enforce the terms of its confidentiality agreement against a former contractor who incorporated a company with almost the same name as the claimant, designed a website using photographs of the claimant’s products, and threatened to misuse sensitive CAD files to fabricate products and pass them off as the claimant’s. Lottie appeared at the ex parte application hearing, the return date hearing, and the disposal hearing (once default judgment was secured).
  • Acting for the defendants (led by James Wibberley) in an employee-shareholder competition case, with the high watermark of the claim value being in excess of £400m.
  • Acting for a defendant (led by Allan Roberts) on a high-value claim involving the alleged misuse of confidential information in the freight forwarding industry. The claim included allegations of breach of the implied terms of the employment contract and/or fiduciary duties, and the economic torts of inducing, or procuring, breaches of contract.

Her advisory work includes:

  • Working with her client to manage misuse of confidential information by an ex director/employee operating in the corporate hospitality industry.
  • Assessing the efficacy of covenants purporting to impose post-termination restrictions on sales representatives in the pharmaceuticals industry.

Lottie accepts instructions in all areas of employment and discrimination law, acting for both claimants and respondents in the public and private sector. Her employee clients include doctors, carers, police officers, journalists and HR professionals. Her respondent clients include Police Forces, a Premiership rugby team, local government, blue chip firms including John Lewis plc, and national recruitment agencies.

Lottie has already appeared, successfully, before the EAT. In Davies v EE Limited [2022] EAT 91, the EAT agreed that the Tribunal had erred in law when finding that the claimant’s pleaded provision, criterion or practice was not applied to her. The claimant’s claim for failure to make reasonable adjustments (ss.20, 21 & 39 EqA) and discriminatory dismissal (ss.39(2) & (7)(b) EqA) were remitted to a fresh Tribunal.

Lottie is regularly instructed to appear in multi-day whistleblowing and discrimination trials (including on issues of Equal Pay). Her drafting and advisory work captures the full suite of employment and discrimination litigation.

Lottie also acts for parties in County Court proceedings involving alleged breaches of the Equality Act 2010.

A growing part of Lottie’s practice is in conducting independent workplace investigations. Lottie’s skillset is particularly well-suited to this discipline.

Lottie was recently instructed to investigate allegations of bullying, harassment, and retaliatory treatment by the chairman of a global manufacturing group towards a junior member of staff.

Lottie accepts instructions in a wide variety of commercial matters.

Lottie is regularly instructed to attend hearings in the County Court and High Court, and her experience of employment tribunal litigation makes her particularly well-suited to appear in long, multi-track trials with lengthy cross-examination of multiple witnesses.
