Albert Barrère, Argot and Slang
“ N’avoir pas de case judiciaire à son dossier is said of one who has never been convicted of any offence against the law. The “dossier” is a record of a man’s social standing, containing details concerning his age, profession, morality, &c. Every Parisian, high and low, has his “dossier” at the Préfecture de Police. ”
