Mugni is currently Head of the Employment Group of 32 barristers at No5. 

Mugni is an experienced employment law specialist who has conducted employment-related hearings in the ET, EAT and civil courts for 20 years. Having qualified in 1996, he practised from chambers in London before moving to in-house employment law advocacy roles in Bevan Brittan LLP and then Eversheds LLP, where he was Head of the Employment Advocacy Unit, before returning to the Bar. Through his law firm experience, Mugni is a firm believer in client care and takes time to understand the needs of the client.

He is a specialist in complex employment litigation and has particular interest and expertise in dealing with high value claims, particularly in the field of discrimination, whistleblowing and/or where there is a High Court connection (e.g. injunctive relief involving confidentiality breaches or in doctors’ disciplinary hearings). He has appeared against or alongside leading employment silks.  

He is a regular speaker on employment law and wider discrimination law issues in the delivery of goods and services. He has recently conducted training sessions for a wide range of clients on the Equality Act 2010. He has also hosted and delivered training through the Employment Lawyers Association (“ELA”). 

Mugni takes an active part in government consultations through the ELA Legislative & Policy Committee, and has contributed to consultation responses on the Public Sector Equality Duty, reform of the Equality and Human Rights Commission, the Single Equality Bill (as it was then), and ACAS reform.

Mugni is currently Vice Chair of the Birmingham Law Society Employment Law Committee.


Recently, Mugni has been appointed as investigator in a number of whistleblowing complaints and grievances. He has also chaired Appeal Panels for universities under their specific Statutes.  

Private Sector

Mugni appears regularly for a number of FTSE100 and FTSE250 clients that are household names. His wider practice also includes acting for airlines, aerospace and engineering, banks and professional services businesses such as accountancy and law firms.

Clients appreciate his commercial yet forensic approach, in particular in cases where the merits of settlement versus fighting a case are finely balanced - for example in whistleblowing claims where very serious allegations of impropriety have been alleged.

He is also experienced in representing employers who wish to protect themselves from their departing employees trying to poach their business, and appears in the High Court on restrictive covenant injunction cases. 

Local Government, Education and NDPBs

Mugni is familiar with the specific needs of NDPBs and local authority clients (particularly in respect of schools) and the complex legislative framework in which they operate. He has many years of experience in acting in discrimination or whistleblowing claims for such clients, but also has experience in acting in niche areas by providing:

  • Advice and representation in termination of employment of senior officers (e.g. Chief Executive or Finance Director) due to gross misconduct, including making submissions to “the designated independent person” under the Local Authorities (Standing Orders) Regulations 1993 (SI 1993/202).
  • Advice and representation on career loss claims brought by senior employees.
  • Advice and representation on transfer of liabilities relating to staff transferring when a maintained school converts to academy status, under TUPE and/or the Academy Act 2010 (as amended) upon dissolution of the governing body.
  • Advice and representation for local authorities providing shared HR and/or legal services under SLAs to other public bodies such as the police.
  • Advice and representation on specialist redundancy issues, e.g. in connection with age discrimination/early retirement, or counter notice issues arising from giving long notice to staff in service critical roles that are to be disbanded in the future.  

NHS/Health Sector

Due to time at Bevan Brittan, Mugni has built up an extensive knowledge of the workings of the NHS/health sector, acting for a whole range of acute trusts, FTs, mental health trusts, and the newly formed CSUs and CCGs. He has experience dealing with:

  • Issues concerning Agenda for Change.
  • Representing NHS trusts and FTs in cases involving doctors’ disciplinary processes under MHPS, both internally, and in connected external proceedings in parallel high court and/or tribunal proceedings.
  • Representing NHS trusts and FTs in cases involving professional misconduct of other healthcare staff and/or relating to Serious Untoward Incidents.
  • TUPE issues arising from commissioning decisions, and advising on the NHS Standard Contract brought since the creation of CCGs.
  • Advising on issues concerning Retention of Employment and/or secondment of staff that are now reaching maturity.
  • Advising and representing NHS clients in cases concerning the use of bank staff.?


“Mugni is brilliant to work with, he really binds the team at tribunal together.  He has been excellent throughout a difficult hearing.” 
Peter England, HR Director, Biofocus UK Ltd.

“My experience of Mugni handling one of our complex TUPE claims was very positive. His advice explored all angles and risks, and the quality of his advocacy was first class.” 
Ian Collier, CEO, Premier Manufacturing, part of the Voigt Group.

“Mugni was a great advocate and cross examiner in a complex employment tribunal case which we won with a unanimous verdict from the panel. His preparation was exemplary and he was a great attorney to have on your side.”
Nicholas Finney OBE, Commissioner at Independent Transport Commission.

“Mugni provides clear and effective professional advice with the focus on the business needs of his clients. He is a good communicator and enjoyable to work with.”
Charlie Millard, Director, M Moser Associates.

‘Mugni is a top class advocate. He gets into the detail very quickly, and is able to identify the key issues. He is also quick to build a rapport with clients and put them at ease.’
David Beswick, Partner and Head of Birmingham Office, Eversheds LLP.

'Mugni has been instructed by myself and colleagues in complex discrimination claims against public bodies. He has provided sound advice in a helpful and pleasant manner and has been well liked by clients. He is highly regarded as an advocate.'
Kate Levy, Employment Solicitor, Warwickshire County Council.

“Mugni is a barrister who can see the whole picture yet able to focus on the key issue to resolve issues in an efficient and cost effective manner.”
Vaikunthan Rajaratnam, Consultant Hand Surgeon, UB, NHS Foundation Trust

“Mugni was always on top of his brief and, unlike some employment lawyers, able to frame his advice around his client's commercial needs. The client feedback I had about his advice and client service was always first rate and I recommend his work wholeheartedly. He's also a pleasure to work with and a technically very strong lawyer.”
Stuart Whitfield, Chief Executive, Bevan Brittan LLP
