Mario Desbordes, the Mayor of Santiago, has reiterated his strong opposition to the proposed expansion of the Santiago 1 prison, arguing that the government’s motivations are primarily financial rather than operational.
Speaking during a visit to monitor progress on works along the Bandera axis, the mayor claimed that the push for the expansion is driven by a desire to avoid immediate costs. According to Desbordes, expanding the current concession allows the treasury to pay in “comfortable installments.”
A Dispute Over Capacity and Classification
The mayor challenged the nature of the project, suggesting that the government is misleading the public. Drawing on his professional experience during the creation of Colina 2 alongside Colina 1, Desbordes noted that those were distinct facilities. He warned that the current proposal is effectively the construction of a “new prison” rather than a mere extension.
A significant point of contention exists regarding inmate capacity. Undersecretary of Justice Luis Silva has stated that the addition of 1,600 spots would allow those currently facing overcrowding in Santiago 1 to move, meaning no new prisoners would arrive.
Desbordes dismissed this logic, stating that the Undersecretary “ignores the history of 100% of the prisons in Chile.” The mayor warned that while 1,600 spots may be created initially, such facilities could see the population grow to 5,000 inmates within four years.
Political Tension and Failed Dialogue
The conflict has extended beyond technical disagreements into a personal clash between the mayor and the Undersecretary of Justice. Desbordes confirmed that he has not had the opportunity to hold meetings with authorities on the matter.
The mayor specifically criticized an invitation from Undersecretary Silva to attend the inauguration of the works. Desbordes described the invitation as a “pachotada” (a mockery or farce) and stated that the Undersecretary “lacked finesse,” concluding that he has nothing to discuss with him given such attitudes.
For his part, Undersecretary Silva previously told La Tercera that the expansion is an advantage for local residents and claimed that Desbordes has been aware of the works for over a year. Silva maintained his confidence that the mayor would eventually attend the inauguration.
Potential Next Steps
Given the current lack of communication, the project may face continued local political resistance. While the government appears committed to the inauguration, the mayor’s technical opposition suggests that legal or administrative challenges could be a possible next step.

the dispute over future inmate numbers indicates that if the expansion proceeds, the municipal government may increase monitoring of the facility’s actual population to verify if it exceeds the promised 1,600-spot limit.
