Ricardo Luis Lorenzetti (born in Rafaela, Santa Fe Province, September 19, 1955) is an Argentine judge graduated from the National University of the Littoral, Argentina, with a long national and international career.
On November 7, 2006, he was appointed Chief Justice, officiated as of January 1, 2007.
He was President of the Commission for the preparation of the Parliamentary Act to reform, update and unify the Civil and Commercial Codes of the Argentine Nation, Presidential Decree 191/2011.Lorenzetti has expressed his view that the Supreme Court should be reduced to seven members, which is the current number (there should be nine, but two seats have been left vacant), since "there must be a true division of powers, which means that the members of the Court should be a number that is independent from the appointments made by a single president."
A statement by UCR figure and former Mar del Plata Mayor Daniel Katz in support of a potential spot for Lorenzetti as Julio Cobos's running mate in the 2011 presidential election led to friction with the administration of President Cristina Kirchner, whose Cabinet Chief, AnĂbal Fernández, expressed disapproval at Lorenzetti's silence on the issue.On 23 June 2013, Lorenzetti claimed that he was being threatened and extorted by AFIP President Ricardo Echegaray.
Lorenzetti claims the intimidation was in response to his verdicts against the constitutionality of government legislation.
