Assessment of general damages for pain and suffering will be based primarily on medical reports from the claimant's treating doctor but, in some cases, the claimant will be examined by a member of the independent medical panel established by the PIAB. A book of quantum will be compiled and published as a guideline to general damages for various categories of injuries and from which parties can satisfy themselves as to the reasonableness of PIAB awards. The existence of this guide should also assist parties in reaching negotiated settlements without recourse to litigation. The existence of a similar book of quantum in England may be reflected in the fact that only 4% of cases there involve barristers compared to their involvement in 70% of personal injury cases in Ireland.
