We study the judiciarisation of resistance to police authority in Brussels from 1945 to 1975, a phenomenon consisting of a certain number of isolated cases of violence against police and constabulary agents. We suggest that the construction of the resistance to police authority as a judicial phenomenon is dominated by police agents. In order to corroborate our thesis we examine police interactions with citizens as well as with public prosecutors and show that in both cases the agents constitute the cornerstone of the judicial construction of the phenomenon. This thesis supports the hypothesis of the magistrates’ professional dependence on the police agents, which has already been proposed by Grosman (1971). We finally illustrate our thesis by a specific example of a violence-against-police-authority case, taken from our sources.
