As a result of the 2015 constitutional reform, the number of seats allocated to Colombian citizens resident abroad was reduced to one, from 2018 onward, as an additional special seat will be created for the territorial constituency of Archipelago of San Andrés, Providencia and Santa Catalina to represent the archipelago's Raizal community.

[1] Since 2014, the assignment of additional seats is based on the corresponding proportional increase of the national population in accordance with census results.

In addition, general rules on the replacement and non-replacement of members depending on different circumstances also apply to both houses of Congress.

Between 1886 and 2014, only one of Colombia's 40 presidents, Gustavo Rojas Pinilla, was charged and sentenced by Congress in 1959 (after the end of his term), and that ruling was overturned by the Supreme Court seven years later.

[6] The government's constitutional reform in 2015 stripped the accusations commission of most of its power and restricted the existing fuero constitucional to the President.

In its stead, the 2015 reform created the Comisión de Aforados, which will investigate and indict the aforementioned judges and Attorney General, even if they may have ceased to exercise their functions.

The commission will be made up of five members elected by a joint session of Congress for individual eight-year terms, from lists sent by the Council of Judicial Government and elaborated through a public competition.

In the case of investigations for unworthiness to serve for misconduct, the new commission shall present its charges, when necessary, to the House of Representatives, which will only be able to suspend or remove the accused from office.
