Low impact type cases

It has been clear for a long time now that a growing area of practice for many people on both sides of the personal injury industry is that of low impact cases. There have been two cases in the last 18 months which have gone as far as the Court of Appeal: Armstrong v First York and Kearsley v Klarfield. However, most cases end at first instance and therefore very little is actually published on the topic. It would be interesting to hear what people´s views are on this topic.
