John Sheath


Practice Overview

John has conducted successful mediations since 2002 ranging from £100,000 to £4m.  He is a vocal advocate of mediation especially in his specialist field of Personal Injury.  In the published book Personal Injury, Major Claims Handling: Cost Effective Case Management, Goldrein de Haas & Frenkel (Butterworths July 2000), John strongly advocated mediation of clinical disputes because of the flexibility and creative remedies in contrast to the limited orders for damages and costs in litigation. He wrote that with a more effective NHS complaints process, there is very little further evidence that needs to be prepared for the parties to properly assess the issues and quantum in order to bring matters to a speedy economic resolution in the interests of all parties.
