On 11 January 2018, the Supreme Tribunal of Justice of Venezuela in exile decreed the nullity of the 2013 presidential elections after lawyer Enrique Aristeguita Gramcko presented evidence about the presumed non-existence of ineligibility conditions of Nicolás Maduro to be elected and to hold the office of the presidency. Aristeguieta argued in the appeal that, under Article 96, Section B, of the Political Constitution of Colombia, Nicolás Maduro Moros, even in the unproven case of having been born in Venezuela, is "Colombian by birth" because he is the son of a Colombian mother and by having resided in that territory during his youth. The Constitutional Chamber admitted the demand and requested the presidency and the Electoral Council to send a certified copy of the president's birth certificate, in addition to his resignation from Colombian nationality. In March 2018 former Colombian president Andrés Pastrana made reference to the baptism certificate of Maduro's mother, noting that the disclosed document reiterates the Colombian origin of the mother of the president and that therefore Nicolás Maduro has Colombian citizenship.
