She has been recognised as a leading junior by the legal directories since 2005, and is named in this year’s Legal 500 ‘Leading Juniors’ list and Chambers & Partners ‘Leaders in their Field’ for 2015 

Lydia acts and advises in a wide range of contentious and non-contentious pensions work. A selection of work from the past year includes:

  • Acting for the Representative Beneficiaries in the IBM v Dalgleish remedies hearing (led by Nicolas Stallworthy QC);
  • Advising The Pensions Regulator on issues including scheme closures, section 75 debts, clearance statements and auto-enrolment;

  • Advising in relation to estoppel and negligent misstatement in a civil court claim;

Pensions/Employment crossover
Given the dual nature of her practice, Lydia has developed a strong reputation in the areas of crossover between pensions and employment law, including:

  • Equalisation and other discrimination issues. Lydia is currently instructed in a high value equalisation claim led by Richard Hitchcock QC;
  • TUPE-related pensions claims, particularly the implications of the Procter & Gamble decision;
  • Breach of trust and confidence and the Imperial Duty, including non-pensionable pay increases and proposed scheme closure.

Statutory schemes
Lydia also has substantial experience of statutory schemes, and has been instructed by employers and individuals in matters relating to the Local Government Pensions Scheme (LGPS), Teachers’ Pension Scheme (TPS) and University Superannuation Scheme (USS). She has also advised trade unions on issues arising from the NHS Pension Scheme and Firefighters’ pensions.

Lydia has substantial experience of employment and discrimination cases at all levels and has a strong reputation for dealing with complex and high profile discrimination matters (notably sex, disability, age and religious discrimination). She has a particular interest in parental rights in the workplace, having advised and acted in many claims relating to maternity discrimination and flexible working and advised the Commission for Equality and Human Rights on aspects of the Equality Act 2010.

Lydia has wide experience of all issues relating to the termination of employment; dealing with both individual and group dismissals. She also deals with issues arising under TUPE, as well as bonus and restrictive covenant claims in the High Court.

She has acted in a number of high profile cases including, in 2014: Tan v McDermott, Will and Emery [2014] – successful claim for pregnancy discrimination, victimisation and unfair dismissal brought by senior solicitor; Weerasinghe v Basildon & Thurrock NHS Trust [2014] – successful whistleblowing claim by a surgeon at a failing hospital.

She co-edits the Discrimination section of Butterworths' Civil Court Practice (The Green Book) and is also a co-editor of Tottels Discrimination Law.

Lydia sits as a part-time Employment Judge in the London South region.
