This Irish case is primarily of interest to psychologists and others concerned about courts’ reliance on evidence from psychologists who are not registered with an appropriate regulator and not clinically trained. The points of general application concern the high threshold to be reached in order to admit as expert evidence the evidence that comes from a body of knowledge that is not widely recognised. 

The court considered that there was some substance to the criticisms of an accident and emergency expert for not dealing with matters in his primary report which he then agreed in the joint report with the opposing expert (who had included the issues in his primary report). These were however criticisms for failing to deal with points, rather than criticisms of the opinions he actually expressed in his primary report.
