Mediator Services

Many cases are now argued, debated and resolved at Joint Settlement Meetings where a clear reasoned approach is necessary to secure a good settlement for the Client. Training to become an Accredited Mediator has widened and strengthened the range of skills available to deploy in negotiations.

David qualified as a Mediator with the ADRg in July 2011 having completed their specialist course in May of that year. He was called to the Bar in 1988 and has been practising in private practice in Chambers in London, Leeds and Newcastle for 29 years.

Mediation in the commercial and civil law context is a powerful technique for resolving disputes of all sizes and types quickly and cost effective. It is robust, quick to set up and recognises the commercial realities of life. In most cases, it has the additional virtues of resolving disputes while retaining or rebuilding personal and business relationships, and dealing with peripheral but important issues, which no court has the remit to do.

David has a substantial and varied practice at the Bar, representing a wide range of Clients in a broad area of law and litigation. He has drawn on that experience and knowledge to help resolve disputes referred to him. He brings awareness, clarity of thought, empathy, realism and robust common-sense to resolving disputes in mediations. He is comfortable dealing with (sometimes complex) corporate structures, SPAs and varied business vehicles (partnerships, JVAs and investment arrangements), commercial agreements and accounts/accounting records. David is also comfortable dealing with disputes which include evidence from Expert Witnesses/Expert Witness Reports.

The mediations David has been involved with have been wide-ranging and largely been business/customer related disputes and disputes with substantial commercial aspects; most reached settlement on the day(s) of the mediation session(s), some in the days after the mediation was completed.

The disputes have included:

  • Technical (Mechanical Engineering) dispute about the construction of an offshore racing yacht mast after its catastrophic failure; the dispute included issues about the validity of FEA computational models, use of materials given the then state of knowledge and the valuation of the sponsorship value of the yacht;
  • SPA in relation to a private Hospital; the dispute was between the Venture Capitalist group and the Surgeons, Doctors and Managers at the Hospital and related to clinical/management decision-making; tax consequences of settlement options;
  • Dispute between commercial funders and Dentist partners in a group of newly established surgeries;
  • Dispute between Barristers over Chambers funds and contributions, withdrawals, borrowings and expenditure;
  • Dispute over development value of a cottage and garden sited on a possible new 'business park';
  • Construction contract; dispute between customer, architect, surveyor and builders; issues about certificates signed for work and done/done incorrectly, non-payment, failure to supervise, inadequate specifications;
  • Boundary dispute regarding encroaching trees/overhanging branches; the boundary was with a School;
  • Clinical diagnostic system failure leading to the inaccurate diagnosis of serious urgent condition/the failure to investigate the condition/symptoms further; one of the issues to be investigated was the interface between the computerised diagnostic tools and the practitioner taking the history from the patient; 

David has a wide ranging practice as a Barrister with specialist interests in business and commercial contract law, intellectual property, human rights (specialising in secure environments, deportation, use of force and the provision of medical services), clinical and professional negligence, judicial review, financial provision in complex cases, company share valuations, Directorships, shareholders, partnership law, HSE Prosecutions and fraud (civil and criminal).
