The 1880 Federalization of Buenos Aires, enacted in a bid to end the internecine warfare between those who favored a united Argentina with a strong central government (
Unitarios) and
Buenos Aires Province leaders who favored an independent nation of their own (
Federales), resulted in President
Julio Roca's passage in 1882 of National Law 1260, which created the presidential prerogative of the appointment of the
Mayor of Buenos Aires (though with a locally elected city council). This remained the city's governing structure in 1993, when former President
Raúl Alfonsín prevailed on his successor, President
Carlos Menem, to agree to a limited
devolution of governing powers to the city (the
Olivos Pact). Accordingly, the
1994 reform of the Argentine Constitution included article 129, which guaranteed Buenos Aires greater self-governance. The
Indentente (
appointed Mayor) was replaced by a
Jefe de Gobierno (elected Mayor), and the city council by the
Buenos Aires City Legislature. Shortly before the historic, June 30, 1996, elections to these posts, however, a senior
Peronist Senator,
Antonio Cafiero, succeeded in limiting the city's autonomy by advancing National Law 24.588, which reserved control of the 25,000-strong
Policía Federal (the federally administered city police), the
Port of Buenos Aires and other faculties to the
national government. The controversial bill, signed in 1996 by President Menem, remained a sticking point between successive Presidents (most of whom have been
Peronist) and Buenos Aires Mayors (none of whom have been). A 2005 agreement on principles between Mayor
Aníbal Ibarra and President
Néstor Kirchner was followed by the modification of the especially contentious article 7, which denied the city its own, local police force, in 2007 - though the "Cafiero Law" otherwise remains in force. Efforts since 2007 by Mayor
Mauricio Macri to declare it unconstitutional have thus far failed, and though the Mayor inaugurated a Metropolitan Police, issues of
revenue sharing for its financing remain pending. ==References==
