Douglas Leach is a specialist Employment & Discrimination barrister.

He has a well-rounded practice which encompasses all areas of employment, discrimination and collective labour law, including County/High Court matters and injunctive relief, and Sports Law related disputes.

He further deals with discrimination issues arising outside the employment context (eg. in the provision of services, education and partnership settings).

Douglas has extensive experience in conducting appellate work in the Employment Appeal Tribunal (EAT) and Court of Appeal, as well as complex multi-week trials.

Expertise

Douglas is an experienced Employment & Discrimination specialist, dealing predominantly with substantial and higher value matters in both the Employment Tribunal and the High Court/County Court across the full range of employment, discrimination and commercial employment issues, including collective labour law.

He is consistently recommended at Band 1/Tier 1 in both Chambers UK Bar and the Legal 500 and features regularly in Who’s Who Legal UK Bar.

Highly regarded for his technical expertise, attention to detail and measured advocacy, Douglas is particularly sought after in complex TUPE, whistleblowing and discrimination matters, as well as employee competition cases involving breach of confidence, restrictive covenants and injunctive relief.

He regularly conducts long-running trials and appeals to the EAT, and has appeared in several significant cases in the Court of Appeal in recent years, usually unled (including against silks).

Douglas acts for both claimants and respondents/defendants, and firmly believes in maintaining this balance. He is regularly instructed on behalf of individuals and/or unions, as well as NHS Trusts and Welsh Local Health Boards, schools and universities, Local Authorities, PLCs and a range of SMEs.

He also acted for government departments during five years on the Attorney-General’s Regional Panel of counsel. He enjoys working as part of a wider legal team and finding creative and pragmatic solutions to problems.

Douglas welcomes electronic instructions, having adopted paperless working practices and is fully conversant with the full range of secure platforms commonly used for video hearings and conferences.

He provides advice and representation in all areas of employment and collective labour law, including:

  • Unfair and wrongful dismissal
  • All forms of discrimination and equal pay
  • Related human rights issues
  • Whistle-blowing
  • Redundancy, reorganisation and insolvency
  • Matters relating to TUPE transfers
  • Contractual disputes, wages and holiday pay
  • Breach of confidence, database rights, restrictive covenants and injunctive relief
  • Industrial action and Trade Union recognition
  • Territorial jurisdiction and private international law
  • Sports-related employment disputes
  • Investigations

    Featured Employment & Discrimination cases


    Bi v E-Act [2023] IRLR 498 (EAT)

    Successful resistance of an appeal against an ET’s refusal to set aside an unless order, and to reconsider that decision, despite after the event evidence of C’s autism diagnosis. There was nothing in that evidence to suggest any unfairness in the ET making its decisions on the papers rather than at hearings. The ET was also entitled to find that the new evidence did not outweigh the impact of C’s failure to provide consent to the disclosure of her medical records pursuant to the unless order, on the ability to conduct a fair trial of remedy.


    Amdocs Systems Group Ltd v Langton [2022] EWCA Civ 1027

    Successful high value unlawful deductions claim in respect of the failure to apply 5% annual increases to the payments due under a contractual income protection scheme, together with an order for costs of £20,000. Respondent’s appeal to EAT on liability dismissed (with limited remission in relation to costs), and further appeal to CA on liability dismissed.


    Commissioner of the City of London Police v Geldart [2020] ICR 920 (EAT); [2021] ICR 1329 (CA)

    Successful claim of direct sex discrimination in respect of the reduction and cessation of a police officer’s “London Allowance” because she was on maternity leave. London Allowance is separate and distinct from “London Weighting” and officers are entitled to continue receiving it in full except where the Police Regulations 2003 provide otherwise. Upheld by EAT, but Commissioner’s appeal to CA partly successful: G was entitled to be paid LA at all times, but the failure to pay it was not direct discrimination. Cross-appeal seeking determination of alternative indirect discrimination claim allowed, and claim remitted to tribunal


    Hextall v Chief Constable of Leicestershire Police [2018] IRLR 605 (EAT); [2019] IRLR 695 (CA)

    Instructed for H. Successful appeal to EAT against a tribunal’s conclusion that the Force’s Shared Parental Leave policy did not discriminate indirectly against men, in only providing the statutory minimum level of pay for Shared Parental Leave. Overturned by CA, primarily on jurisdictional grounds that the claim was in truth an equal pay claim.


    Martin v University of Exeter (30.8.18, UKEAT/0092/18/LA)

    Instructed by the University. Successful resistance of an appeal against an Employment Judge’s conclusion that the Claimant was only disabled from a point in time which meant that most of his discrimination claims could not succeed. Where it is asserted that a condition’s effects are “long term” because they are “likely” to last at least 12 months, the test is predictive, and expert evidence will usually be required.


    Secretary of State for Business, Enterprise and Regulatory Reform v Parry and anor [2016] ICR 1140 (EAT); [2018] ICR 1807 (CA)

    Instructed by the School trustees in the EAT and Court of Appeal. The procedure in Rule 12(2A) of the 2013 ET Rules of Procedure – whereby an Employment Judge is required to reject a claim form that “cannot sensibly be responded to” – is not ultra vires. However, on the facts, a claim form which mistakenly attached particulars for an entirely unrelated case, could sensibly be responded to because the box for “unfair dismissal” had been ticked.


    NHS Business Services Authority v Young [2017] ICR 599 (CA)

    Success in an unusual statutory appeal to the Chancery Division from a decision of the Pensions Ombudsman, concerning the correct construction of the NHS Injury Benefit Regulations 1995 in relation to the test of causation of loss of earning ability (an element of the entitlement to Permanent Injury Benefit). Successfully resisted NHS BSA’s appeal to the Court of Appeal.


    Griffiths v Secretary of State for Work and Pensions [2017] ICR 160 (CA)

    Instructed for DWP. Successful resistance of a second appeal against the dismissal of a reasonable adjustments claim in relation to disciplinary action taken pursuant to the DWP attendance management policy. While the duty to make adjustments had arisen, it had not been breached. It will rarely be reasonable to have to make adjustments in respect of the wholly subjective disadvantage of “stress”.


    Coles v Ministry of Defence [2016] ICR 55 (EAT)

    Instructed for C. Temporary agency workers have a right to be informed of permanent vacancies on an equal footing with permanent employees, but do not have a right to apply for those vacancies. Application for a reference to the ECJ on the meaning of the Temporary Agency Workers Directive refused. The tribunal had erred however, in finding that the chosen comparator was not a “comparable worker”.


    Personnel Hygiene Services Ltd & ors v Rentokil Initial UK Ltd & anor [2014] EWCA Civ 29

    Successful substantial High Court (Bristol Mercantile Court) breach of confidence claim for final injunctions restraining use of customer information, including a springboard injunction and successful resistance of an appeal (led by Hugh Sims QC in the Mercantile Court and Court of Appeal).


    Ajayi and anor v Aitch Care Homes (London) Ltd 03.02.12, EATPA/0262/11; Harvey Bulletin 406 (May 2012)

    For a dismissal to be automatically unfair for the principal reason of the employee refusing (or proposing to refuse) to forego a rest-break under s.101A ERA 1996, that refusal must be explicit: implicitly purporting to refuse by sleeping was not enough.


    Fulcrum Pharma (Europe) Ltd v Bonassera and anor 22.10.10, EAT/0198/10; Harvey Bulletin 389 (Dec 2010)

    Instructed at appeal stage. Successfully resisted appeal against finding of unfairness in “pool of one” unfair redundancy dismissal claim. Assumption that the occupant of redundant post had to be dismissed was unfair.


    Chief Constable of Gloucestershire Constabulary v Peters 14.07.10, EAT/0322; [2010] All ER (D) 192 (Nov)

    No indefinite stay of tribunal proceedings pending outcome of potential criminal trial.
