L'Affaire des Fiches de délation (“affair of the cards of denunciation”) was a political scandal in France in 1904-1905 in which it was discovered that the militantly anticlerical War Minister under Emile Combes, General Louis André, was determining promotions based on a huge card index on public officials, detailing which were Catholic and who attended Mass, with a view to preventing their promotions. It is also called in French "L'Affaire des casseroles"; casserole being slang for spy.
Both Combes and André were Freemasons, and much of the information had been collected by the Masonic Grand Orient de France. Discovery of this by the media undermined the government.
