Legal terminology is distinguished by its precision and its roots in specific legal systems. Gérard Cornu highlights its dual technical and cultural role, while Jean Carbonnier emphasizes its normative power. Legal argumentation, essential for interpreting and justifying decisions, is based on structured reasoning and appropriate discursive strategies. Frédéric Rouvière stresses its role in the legal qualification of facts. Robert Badinter’s discourse illustrates the interplay between legal technicality and rhetorical persuasion, particularly in his plea for the abolition of the death penalty. His use of professional legal French combines terminological rigor with accessibility, drawing on historical, ethical, and
legal references to persuade. The effectiveness of his argumentation relies on logical structure, striking rhetorical devices, and the appeal to universal values of justice and humanity.
