[2] On 7 August 1990, the newly inaugurated President of Colombia, César Gaviria Trujillo, appointed Carrillo as Presidential Adviser on Constituent Assembly Matters.

[3] Because of constitutional restrictions on sitting officials, Carrillo resigned his post to run for a seat in the Constituent Assembly,[4] feat that he managed when the elections were held in December.

[5] Carrillo, who at the time was serving as Assemblyman and Chairman of the Justice Committee of the Constituent Assembly, was replaced as Chairperson by Assemblywoman Martha Lucía Pinzón Galán.

On 24 January 2012 during the inauguration of Beatriz Londoño Soto as Minister of Health and Social Protection, President Juan Manuel Santos Calderón announced the designation of Carrillo as Director of the National Legal Defence Agency,[8] a newly created executive agency ascribed to the Ministry of Justice and Law, and charged with coordinating, organizing, and structuring the country's legal defence, and whenever possible, avoid damages to the State's assets.

[12] The day after his resignation, President Santos announced the designation of Carrillo to succeed Orlando Sardi de Lima as Ambassador of Colombia to Spain.
