Justin Quinton

Principal Lawyer

I'm a principal lawyer in the employment department and head up the national OMS employment team at Slater and Gordon Lawyers.

Expert profile of Justin Quinton

Get to know Justin

I'm a solicitor with over 10 years post qualification experience specialising in employment and data protection. I have acted for both claimants and respondents in contentious and non-contentious matters, including conducting my own advocacy. I also have considerable general commercial experience and I'm a qualified mediator.

I cross-qualified as a solicitor in 2009, after having originally been called to the Bar. I've been with Slater and Gordon for over two years. Prior to joining Slater and Gordon, I worked for/with trade unions and professional associations for over 13 years and helped to establish my previous firm as an independently regulated law firm in 2015.

My breadth of expertise means that I am uniquely positioned to support trade unions, staff associations and their members in all aspects of employment, industrial and trade union law.

Career highlights

University College London v Mr T Brown - I successfully acted for a trade union representative in an appeal to the Employment Appeal Tribunal by his Russell Group university employer against his successful complaint to the employment tribunal that he was subjected to a detriment on grounds related to trade union activities.

Jennings v GMB - I successfully defended a large trade union against a complaint to the Certification Officer by a member on the grounds of breach of trade union laws relating to payments for political purposes.


I have been recognised in the Legal 500 as a key lawyer, and I am a member of the Employment Lawyers Association.

The 2022 edition of Legal 500 states: “I work extensively with senior associate Justin Quinton who is extremely hardworking and very dedicated to the cases we work upon. He is a pleasure to work with as he is very personable whilst also being very sensible and measured in his approach. Despite picking up the cases part-way through he has made considerable effort to get up to speed and handles the complex matters very well despite not having had the years of working on them that the rest of us in the legal team have!"
