Judges' socio-technical review of contested expertise

This article investigates how civil court judges practice meta-expertise in cases that feature contradictory and inconclusive medical expertise. The empirical case study consists of a sample of eleven Helsinki district court verdicts from 2014–2017, drawn from a larger number of similar traffic insurance compensation cases. The case-type features a medical controversy concerning traumatic brain injury (TBI) diagnostics. I contend that the difficulties judges face in evaluating the medical expertise result from epistemic asymmetries between legal and medical professionals. This study highlights the importance of explaining and understanding how judges overcome uncertainty and discriminate between expert positions. Drawing from earlier studies on meta-expertise and judges’ practice of evaluating expertise in court, I introduce the concept ‘socio-technical review’ to describe judges’ practice of facilitating highly technical and esoteric scientific expertise to needs of judicial decision making. I argue that socio-technical review is a special form of practicing meta-expertise, which effectively allows meta-experts to manage epistemic asymmetries. In examining how meta-expertise is practiced in the TBI case-type, the paper contributes to general sociological understanding of decision-making under uncertainty and suggests further studies in comparable settings.Peer reviewe
