 Shortly before the historic, June 30, 1996, elections to these posts, however, Senator Cafiero succeeded in limiting the city's autonomy by advancing National Law 24.588, which reserved control of the Argentine Federal Police (the federally administered city force), the Port of Buenos Aires and other faculties to the national government.The controversial bill, popularly known afterward as "Ley Cafiero" (the "Cafiero Law") was signed in 1996 by President Menem, remaining a sticking point between successive Presidents (most of whom have been Peronist) and Buenos Aires Mayors (none of whom have been).Cafiero was re-elected as Senator in 2001.
