This essay offers the first description and analysis of the judicial work of the Extraordinary Court of Assize of Lucca (Tuscany), which brought to trial the crimes of collaborationism with Nazi-fascists committed in the area between 1943 and 1945. The data on the activities and on trials celebrated by the court from 1945 to 1947 are given; then, particular attention is paid to a court case with a woman accused of having relations with the fascist political police, which, even though it may look like a less important case and trial, gives the opportunity to show the peculiarities and critical issues of this special judicial practice against fascist crimes and, also, the hidden importance and spreading of «secondary» collaborationism.
