Practice Overview

Patrick Halliday has an employment, procurement, public and commercial law practice.  He is recommended for procurement law in the Legal 500 and for employment law in both Chambers & Partners and the Legal 500.  The directories comment that he has a “calm and persuasive demeanour that works wonders with judges”; “is meticulously well-prepared”; “knows his cases inside out”; is “a very strong junior”; is “extremely fast-thinking”; is “an excellent cross-examiner”; is a “confident and reliable” advocate;  “has a simply incredible recall of fine points of law and facts”; and “has real skill in distilling complex scenarios”.

Patrick was appointed to the Attorney General’s ‘B’ panel of counsel in March 2014.

He obtained a first class degree in Social and Political Sciences from Pembroke College, Cambridge University; and a distinction in the law conversion course at City University.


Patrick practises in all areas of employment law.  Much of his recent work has involved discrimination and whistleblowing claims in the financial services and health sectors; and injunction applications against former employees.

Current and recent cases include:

  • Ali Dizaei v Commissioner for the Metropolitan Police and others:  acting (led by Clive Sheldon QC) for the Metropolitan Police Authority, in a high profile race discrimination and victimisation claim, which was named by The Lawyer as one of its ‘Top 20 Cases of 2013’;
  • acting (led by Daniel Stilitz QC) for a well-known global investment bank in a high value sex and pregnancy discrimination claim;
  • acting (led by Christopher Jeans QC) for one of the UK’s top four retailers in a very high value claim by three hundred employees for equal pay;
  • Emmanuel v City & Hackney Teaching Primary Care Trust and Secretary of State for Health [2011] EqLR 1291 (led by Adrian Lynch QC):  successfully arguing on behalf of the Secretary of State a genuine material factor defence in a national test case for equal pay claim by NHS nurses.

He acts regularly as sole counsel in multi-day employment tribunal trials concerning all aspects of statutory employment law.  He appears regularly in the Employment Appeal Tribunal.


Patrick specialises in procurement law.  He regularly advises both contracting authorities and tenderers on a wide range of procurement issues.

His recent litigious work for claimants includes acting in the High Court:

  • (led by Nigel Giffin QC) in a claim against the Legal Services Commission concerning a tender for legal aid work (settled on terms favourable to the claimant);
  • (as sole counsel) against two primary care trusts, in a claim concerning procurement of cancer screening services (settled on terms favourable to the claimant).

He also acts for defendants in procurement litigation.  Recent or current work includes:

  • Shepherd Offshore Ltd v North Tyneside Council (led by Nigel Giffin QC): litigation which included both a claim under the Public Contracts Regulations 2006, and a judicial review challenge to the alleged grant of state aid;
  • Fujitsu Services Ltd v (1) Department for Transport (2) IBM United Kingdom Ltd (led by Nigel Giffin QC):  ongoing litigation about novation of public contract without a competition when the contractor’s business is acquired by a third party.

Increasingly, his procurement work has involved advising on state aid.  He has advised on the state aid aspects of transport infrastructure, support for community services, guaranties for 'in-house' procurement bids by local authorities and regeneration projects.

He edits (with Jason Coppel QC and Joseph Barrett) 11KBW’s Procurement Law Newsletter.  He delivers talks on procurement law, including on the new Directives.


Patrick has been a member of the Attorney General’s ‘B' panel since March 2014, having previously been on the ‘C’ panel, and has acted in numerous claims for judicial review across a range of areas, including prisons, immigration, social security, libraries, human rights and the public sector equalities duty.  His public law work includes the following. 

  • R (Hurst) v London North District Coroner [2007] UKHL 13 and Jordan v Lord Chancellor [2007] UKHL 14 (led by the Attorney General and   Philip Sales QC):  Article 3 ECHR, coroners’ inquests and application of the Human Rights Act 1998 to deaths pre-dating the Act;
  • R (Moyse) v Secretary of State for Education [2012] ELR 551 (led by Clive Sheldon QC):  the only reported case on academy conversions  under the Academies Act 2010;

Between 2008 and 2011 Patrick was junior counsel to the Baha Mousa Inquiry into the death of Baha Mousa in British Army custody in Iraq in 2003 and into the use of “conditioning” techniques by British soldiers.  During approximately 100 days of witness evidence Patrick was responsible for examining a number of witnesses on behalf of the Inquiry.


Patrick’s commercial practice focuses on the commercial aspects of employment law, including injunctions, confidential information, restrictive covenants, the poaching of employees in unlawful team moves, bonuses and the attempted diversion of business opportunities by employee fiduciaries.  His recent and current commercial work includes:
