The fourth power. a mapping of police oversight agencies in Europe and Quebec

Independent police oversight bodies are advocated by human rights organisations to be the most credible and effective solution to address the misbehaviors and systemic malfunction. They have emerged in parallel with independent regulatory agencies in various economic sectors, thus signalling a new trend in governance interpreted as the rise of a 'fourth power.' Still, comparative knowledge is scarce about the nature of delegation of power to police oversight agencies (POAs) and their actions. By analyzing 25 POAs in 20 countries, this article seeks to precisely describe their features in Europe and Quebec (Canada): the timeline of their birth, the scope of delegation (remit, formal independence, powers, resources), and the variations in how they execute their mandate. We unveil a profound heterogeneity across countries. In terms of national patterns, the main divide is between specialised (police only, limited formal independence, more abundant resources) and non-specialised (all public administrations, strong formal independence, limited resources) agencies. The latter tend to act as a public fire alarm to compensate for their lack of resources. Our mapping also contrasts European countries' oversight mechanisms, which rely on professional agencies that are mostly established at the national or state/regional level, with local civilian oversight boards in the US. And, while our results confirm that the 1990s marked a watershed, they question the notion that agencification in the police sector has been a vector for revolution in its governance, since no POA incorporates all the traits required for them to be the fourth power just yet.
