1. What is the Political Constitution of the Republic?
It is the fundamental regulatory body of our country’s Rule of Law, which sets forth the basic principles and rights for civil coexistence in the country, thereby regulating the relationship between the State and its citizens. It also establishes the general guidelines under which the State’s branches and their main public bodies and agencies must operate.
Every law or legal rule must abide by the principles and provisions enshrined in the Political Constitution of the Republic.
2. Constitutions in Chile’s History
Throughout its history, Chile has had various constitutional bills. However, three have been the main constitutions that have governed during the history of our Republic.

a. Political Constitution of 1833
Drafted on the basis of the constitutional bill of Mr. Mariano Egaña, the 1833 Constitution was discussed and approved by the convention of 1833, being the fundamental charter with the longest period of validity in our country. It laid the foundations of the Republic of Chile as a unitary and sovereign State, whose president is the head of State and Government, with a bicameral National Congress and an independent Judiciary.
b. Political Constitution of 1925
Drafted by a commission presided over by the President of the Republic at the time, Mr. Arturo Alessandri Palma, and approved on August 30, 1925. Its main purposes were to endow the President of the Republic with more powers vis-à-vis Congress, granting the President, among other powers, the exclusive initiative to submit laws on certain matters for discussion and enactment. It also enshrined the separation of church and state, as well as freedom of religion.
c. Current Political Constitution
The constitution currently in force in our country was drafted by the Commission for the Studies of the new constitution, presided over by Mr. Jorge Alessandri Rodríguez (former President Alessandri Palma’s son) and Mr. Enrique Ortúzar. Its final text was approved on Thursday, September 11, 1980.
3. Current Political Constitution of the Republic
Main aspects regulated by the Constitution
Our Political Constitution of the Republic is structured into fifteen chapters that regulate the following matters of our Rule of Law:
- Basis of Institutionality
- Nationality and Citizenship
- Constitutional Rights and Duties
- Government
- National Congress
- Judiciary
- Public Prosecutor’s Office
- Constitutional Court
- Electoral Justice
- Comptroller General’s Office of the Republic
- Armed Forces, Forces of Order and Public Security
- National Security Council
- Central Bank
- Internal Government and Administration of the State
- Reforms to the Constitution
From the mentioned chapters we highlight the following:
- Basis of Institutionality
This is the first chapter of the Constitution and contains the set of principles on which the Republic of Chile is built. It enshrines freedom and equality in dignity and rights for all persons; it declares family as the fundamental nucleus of society; intermediate groups that conform society are protected; promotion of common good is established as the State’s purpose; Chile is enshrined as a unitary State and a Democratic Republic; the rights guaranteed by international treaties ratified by Chile are recognized; principles of legality, prior investiture, transparency and probity for the operation of the State’s bodies are enshrined; and terrorism is condemned for being contrary to human rights. - Government System
This chapter defines the President of the Republic as the head of State and head of the Government, who is entrusted with its administration, the preservation of internal public order and the external security of the Republic. To this end, the Constitution grants the President a broad range of exclusive powers. It also enshrines the provisions concerning the appointment and requirements of the Ministers of State, ordering the passing of an organic constitutional law to establish the General Basis of State Administration. Finally, it defines the Constitutional States of Exception. - Constitutional Guarantees
Chapter III of the Constitution regulates a wide variety of fundamental rights enshrined in favor of persons. Among the constitutional guarantees protected by the Constitution are: the right to life and physical and psychological integrity; equality before the law; equal protection of the law in the exercise of rights; the right to a legal defense; respect and protection of private life and honor; the inviolability of the home and private communications; freedom of conscience and religion; the right to personal freedom and individual security; the right to live in a pollution-free environment; the right to the protection of health; the right to education; freedom of speech and to inform without prior censorship; the right to associate; freedom of work; the non-imposition of disproportionate or unfair taxes; the right to carry out any licit economic activity; non-discrimination in economic matters; the right to property, subject to the relevant legal and constitutional limitations; copyright and the right to the creation of works of art; and, the right to the non-limitation of the constitutional guarantees in their essence.
In order to safeguard some of these guarantees, the Constitution provides for a constitutional protection action, which may be lodged by the affected person or by anyone on their behalf before the relevant Court of Appeals in order to request the measures deemed necessary for the due protection of such person. - Regulated Bodies
The current constitution sets forth the general guidelines for each branch of government: Executive Branch, Legislative Branch (National Congress), and the Judicial Branch. It also enshrines the regulation of several public bodies relevant for the State, among these, the Public Prosecutor’s Office, the Constitutional Court, the Comptroller General’s Office of the Republic, the Armed Forces and the Forces of Order and Public Security, the Central Bank, and the Interior Government and Administration of the State (regional, provincial and municipal). The details of these public bodies are regulated in organic constitutional laws.
