John is also one of London's leading solicitors in restrictive covenant disputes and an experienced High Court practitioner. He has obtained numerous injunctions for a range of leading corporate clients, in the High Court, in recent years. John has a very solutions orientated and commercial approach.

John qualified as a solicitor in 2001 and as a barrister in 1993. He is an experienced advocate and has years of experience in litigating in the Employment Tribunal, and the Employment Appeal Tribunal in unfair dismissal, whistleblowing and equal opportunities cases.

John's client base is entrepreneurial and this prompted him to set up Constantine Law.  Before this, he headed the London employment team of a large national law firm.

John has particular expertise in business protection and works closely with some of the leading barristers in the field to protect his client's commercial interests. He has great experience in the arena of a-typical working, including consultancy agreements, IR35, CIS and the tax implications of each. He works closely with leading accountants to provide joined-up solutions for his clients.

John is a member of the Employment Lawyers Association and the leading Irish entrepreneurial organisation, the Irish International Business Network (IIBN). He is also an active member of the Institute of Directors (IOD). John appears regularly on news media including the LBC and Television.
