In this last chapter, I want to identify the categories that judicial members mobilized in the context of the Queen Boat trial. Insofar as there is no explicit characterization of homosexuality in Egyptian law, its sanction could only operate through assimilation to penal categories that were judged as analogous. We thus witnessed the activation of a whole categorial device through which homosexuality was designated, labelled and provided with penal consequences. I seek now to observe the production of these categories, their organization, their praxeological grammar, the functioning of their inferential power, and their legal fixation and formalization.
