Since the adoption of the city's Constitution in 1996, Buenos Aires has counted with a democratically elected executive; Article 61 of the Constitution of the states that "''Suffrage is free, equal, secret, universal, compulsory and non-accumulative. Resident aliens enjoy this same right, with its corresponding obligations, on equal terms with Argentine citizens registered in the district, under the terms established by law''." The executive power is vested on the Chief of Government (), who is elected alongside a Deputy Chief of Government. In analogous fashion to the Vice President of Argentina, the Deputy Chief of Government presides over the city's legislative body, the City Legislature.
