Sean O’Brien Direct Access

Call: 2001


Having established a civil practice including general commercial and property matters, Sean has for some time specialised principally in employment and discrimination law.

Sean’s cases usually involve the most complex legal and factual backgrounds and the most serious allegations of discrimination and misconduct, acting for both claimant and respondent.  In particular, Sean is highly experienced in handling cases comprising a multiplicity of allegations and causes of action.  He was instructed in a 6-week race, religion and disability discrimination case involving well over 1,000 permutations of allegation.

Sean has extensive experience of all aspects of proceedings in the Employment Appeal Tribunal.   Sean is also well-versed in the military disciplinary hearings and grievance regimes including Courts Martial.

As a trained mediator Sean is often instructed to facilitate dispute resolution between parties and has acted as mediation advocate with considerable success.

Prior to practising law, Sean was a senior air force officer, and completed his degree dissertation in the field of aviation law. He concluded his career in the British Embassy in Moscow. Whilst Sean is qualified as a military interpreter, he is capable of translating most Russian legal documentation. He relishes any opportunity to keep his linguistic skills fresh.

Sean is well-regarded as a personable but highly effective advocate, skilled at putting the lay client at their ease and cutting to the heart of his opponent’s case.

Sean sits as a fee-paid employment judge in the London East Employment Tribunal, and is unable to accept instructions in that region.
