The term "Cabinet" does not appear in the Constitution, where reference is made only to the Secretaries of State.
Article 26 of the Organic Law of the Federal Public Administration (Ley Orgánica de la Administración Pública Federal) creates the several cabinet secretariats, and the Organic Law of the Attorney General's Office (Ley Orgánica de la Procuraduría General de la República) creates the office of the Attorney General.
