Mediation overview
John was accredited as a mediator by CEDR in 2001 since when he has acted as lead mediator in over 100 cases, as well as being an advocate in many more. He is a member of the Standing Conference of Mediation Advocates and occasionally mediates pro bono for Law Works. He is recommended as a “very good” mediator by Legal 500.
As a facilitative mediator, John will suggest solutions but not attempt to evaluate the merits of a party’s case, let alone try to give legal advice. John’s experience is that time and patience can resolve almost all disputes, but that the process cannot be rushed. In the well-used language of mediation, he is in charge of the process but the clients are in charge of the product.
You can view here an example of John’s standard mediation agreement. A detailed explanation of the mediation process can be found on our mediation pages. There are excellent mediation facilities available at Gatehouse Chambers, and John can also recommend venues in the Midlands. He is also prepared to travel as necessary.
John is a judge at the annual ICC International Commercial Mediation Competition.
To discuss a possible mediation appointment in confidence, please feel free to contact John direct. Alternatively you can speak to a member of the Practice management team.
