Medellín & Durán lawyers

In 2010, he partnered with Rodrigo Durán Bustos, another Colombian lawyer to start a public law firm named Medellín & Durán Abogados. Although the firm specialized in public law, it has also had cases of other law areas like constitutional law, state contracting, cadastral law, disciplinary law, and fiscal responsibility. The firm was named member of the American Bar Association (ABA) in 2021, and in 2022 was ranked by Chambers and Partners as one of the best Latin-American public law firms. In 2023, Medellín was also ranked by Chambers and Partners as one of the best public lawyers in Latin America.

Minister of justice and law

Medellín was appointed Minister of Justice and Law of Colombia by President Ernesto Samper Pizano on 11 January 1996, replacing Néstor Humberto Martínez Neira.^[2] As minister of justice and law he settled the domain extinction law or "Ley de extinción y dominio" which was made to economically punish drug dealers who acquired estates or other things in their patrimony in an illicit way or through drug money. The law implied that in case there was a condemnatory sentence, the government would become the owner of the things acquired by drug money or in a illegal way.

Not long after, Medellín recused himself from handling a case pertaining to the Palace of Justice siege because of the personal connection to the case, since his father was a fatal victim of the siege. The Minister of the Interior, Horacio Serpa Uribe, was therefore named Minister of Justice ad hoc.^[3]

He was ultimately forced to resign on 21 April 1997 because he was an open supporter not only of opening up the debate for an extradition treaty with the United States, but also of having it implemented retroactively, something both the President and the Minister of the Interior were completely against, and ultimately leading to incompatibility with the Samper administration.^[4][5]

Ambassadorship

On 7 December 2006, Medellín was appointed Ambassador of Colombia to the United Kingdom of Great Britain and Northern Ireland, and Concurrent Non-Resident Ambassador to the Republic of Ireland, and presented his credentials to Queen Elizabeth II in a ceremony at Buckingham Palace on 2 March 2007.^[6]

While in office, Guillermo Fernández de Soto, Colombia's Ambassador to the Netherlands resigned, and President Uribe moved quickly to appoint Medellín as new Ambassador pending his return to Colombia to be sworn in, so on 19 November 2007, Medellín resigned his post and returned to Colombia. His nomination for Ambassador to The Hague was a matter of great importance, given the case at the Permanent Court of Arbitration on the sovereignty claims of Colombia over the Archipelago of San Andrés, Providencia and Santa Catalina after Nicaragua presented a dispute case over the territory, and the President believed Medellín's law background would help Colombia's cause in court. But suddenly, latter that month, Medellín turned down both Ambassadorships, when an article in El Espectador revealed that Carlos Alberto Gaviria Vélez, older brother of José Obdulio Gaviria Vélez (cousin of Pablo Escobar), who was an Advisor to President Uribe, was directly involved with Luis Carlos Molina Yepes, the moneyman involved in planning the assassination of Guillermo Cano Isaza, Medellín's father-in-law.^[7] His resignation was coupled with an earlier one from the Anticorruption Czar, Rodrigo Lara Restrepo, who resigned because José Obdulio Gaviria Vélez had deliberately lied to him about an article published by the Miami based El Nuevo Herald, where they discussed the death of his father, Rodrigo Lara Bonilla. The result of the resignations, both linked to the President's advisor, created a political storm in Colombia.
