The Republic of Chile is ruled by the Constitution of 1980 (October 24th, 1980 with several amendments–the most important were mainly in 2015).

2. Constitutional Principles

Democratic State: This Constitution guarantees the full exercise of political rights, in accordance with the principle of popular sovereignty and with the laws derived the Constitution. Suffrage shall be universal, equal, secret, and compulsory.

Rule of Law: The citizens and public powers are subject to the Constitution and the legal order. The constitutional intent is to guarantee the principle of legality, the normative order, and the non-retroactivity of punitive provisions which are not favorable to, or which restrict, individual rights, legal security, and the interdiction of arbitrariness of public powers. The declarations, rights, and guarantees which the Constitution enumerates shall not be construed as a denial of other rights and guarantees not enumerated, or in opposition to the core of these rights and guarantees.

Legal Remedies: All persons have the right to the effective protection of the judges and courts in the exercise of their rights and legitimate interests, and in no case may there be a lack of defense. When the right damaged, limited, modified, or threatened affects physical liberty, or in case of an illegitimate worsening of procedures or conditions of detention, or of forced missing of persons, the action of habeas corpus (“Recurso de Amparo”) shall be filed by the party concerned or by any other person on his behalf, and the judge shall immediately make a decision even under state of siege.

Any person shall file a prompt and summary proceeding regarding constitutional guarantees (“Recurso de Protección”) provided there is no other legal remedy, against any act or omission of the public authorities or individuals which currently or imminently may damage, limit, modify, or threaten rights and guarantees recognized by this Constitution, treaties, or laws, with open arbitrariness or illegality.

Nulla Poena Sine Lege: No one may be convicted or sentenced for actions or omissions which when committed did not constitute a crime, misdemeanor, or administrative infringement as established by legislation in force at that moment.

The Civil Administration may not impose sanctions which directly or indirectly imply the deprivation of freedom. Special commissions to judge citizens are forbidden. No inhabitant of the nation may be punished without previous trial based on a law enacted before the act that gives rise to the process, nor tried by special committees.

No Tax without Law: Only by law can the government establish new taxes. The exclusive initiative in the matter belongs to President. The originating House for that shall be the Chamber of Deputies.

Non-Discrimination: Any form of discrimination is forbidden.

Free Enterprise: Free enterprise within the framework of a market economy is recognized. The public authorities guarantee and protect its exercise.

Property Protection: There are wide and strong protections for any form of property at the constitutional level.

3. Government Structure

Chile is a centralized country ruled by a presidential system. The Head of State is elected by direct universal suffrage every four years (Constitutional amendment in September 2005). Currently the President is Sebastián Gabriel Boric, who has held the office since March 11, 2022 (Presidente de la República).

He is the supreme head of the nation and head of the government, and he is politically responsible for the general administration of the country. The President of the nation shall be directly elected by the people, by second ballot, according to the Constitution. If in the first ballot a candidate obtains more than fifty percent of the affirmative votes validly cast, he or she shall be proclaimed President of the Nation.

The President designates his ministers, who are only responsible to him. The Constitution (chapter V) creates a bicameral legislature known as the National Congress, consisting of the Senate (Senado de la República) and the Chamber of Deputies (Cámara de Diputados). All the members are elected by universal, free, equal, direct, compulsory, and secret suffrage under the terms established by law.

The main function of Congress is to enact laws. The Senate has fifty members (two from each electoral district (circunscripción) of the country), elected to an eight-year term. The Chamber of Deputies has 155 members (one from each electoral district of the country), elected to a four-year term. See Biblioteca del Congreso Nacional de Chile.

Each chamber has standing committees that prepare and draft legislation. They both pass the statutes. The election in each district shall be conducted in keeping with the criteria of the proportional system (D’Hondt system).

4. Types of Legislation

Chile is ruled by a hierarchy of norms. An overall norm is the Constitution. Under this text, Parliament should pass the laws or statutes (Ley), with an internal hierarchy: institutional act (Ley orgánica constitucional), special act (Ley de quorum calificado), andordinary act (Ley ordinaria) due to quorum of approval and depending on matter. The former institutional law and especial act will be submitted from 2022 to the same procedure as every law (Law N° 21.535, January 2023).

Within the ordinary act or ordinary law, you have to consider Decree Law (Decreto Ley), “Decreto con Fuerza de Ley” or “D.F.L.” (delegated law) and Ordinary Law, all of which are of equal hierarchy. The above-mentioned legislative initiatives, in the order they have been described, establish the hierarchical principle.

The executive power has the right to enact regulations (reglamentos), which are called “Decretos Supremos” and are issued by the President of the Republic, and plain “decretos” or “resoluciones,” which are issued by the rest of the executive branches. All laws, supreme decrees, and the most important documentation from the executive branch are published in the official gazette (Diario Oficial). The laws receive unique and correlative reference numbers (now we are on number 21,000).

4.1. Ordinary Laws

Ordinary Laws (Ley ordinaria) are common laws, in the essential meaning of the word. They are laws originating from the legislative branch, in the exercise of its primary legislating function. They deal with specific subjects, except those which will be specifically dealt with by the President. Approval requires one reading in each house of the National Congress, with the vote of a simple majority of the present members, and sanction by the President of the Republic.

The Congress has a residual power to enact law only in specific matters, which is nevertheless very general and comprehensive. Certain matters should only be regulated by law, like human rights, taxes, matter subject to actual codes, etc. Bills about specific issues, like taxation, can be initiated for the President of the Republic only in the Chamber of Deputies.

The law-making process is comprised of seven steps:

  • initiative;
  • debate;
  • voting;
  • passing;
  • sanction or veto;
  • enactment;
  • publication;

The President takes part in the making of laws according to the Constitution. The right of bill initiatives belongs to the President or to each member of the chambers, depending on the matter.

The legislative process begins with a bill of law (called “Proyecto de Ley”) in one of the houses–the Chamber of Deputies or the Senate, thus called the originating house. Within the originating house, the bill of law is submitted to a technical, material, and formal analysis, which is carried out by the corresponding committees of that house. The Chamber of Deputies has thirty permanent standing committees, and the Senate has nineteen.

If the bill of law is approved by the competent committees, it is forwarded to the plenary assembly to be voted on. After being voted on, it is dismissed if rejected or forwarded to the House if approved.

The reviewing process of the house takes place in the body that did not originate the bill of law. If the bill is rejected, it is dismissed; if it is amended, it is returned to the originating House for re-evaluation. Exceptionally, the House can make a special joint committee of members from each Chamber to approve the project; if it is approved, depending on the object of the bill, it is forwarded to the President of the Republic to be endorsed or vetoed.

Upon receiving a bill of law, the President of the Republic may sanction it or veto it in whole or in part. However, a veto is not an absolute decision–rather, it can be overridden by two thirds of the members of the National Congress. If the veto is overridden, the bill shall be sent to the President of the Republic for promulgation and is published.

4.2. Decree or Delegated Laws (Decreto con Fuerza de Ley or D.F.L.)

The Congress may delegate to the President the power to set norms with the status law on specific matters. They are issued by the President, by means of delegation of competence from Congress in the specific matter. The President (the delegate) would not normally have competence to prepare that law but has acquired the power to do so by virtue of delegation from the first one (the delegating authority). Certain exclusive competences may not be delegated; for example, rules about human rights. These regulations are common in technical matter like electric area, water supplies, or health standards.

An Institutional Act (“Ley Orgánica Constitucional”) is a separate law, as its name indicates, since it supplements the Constitution without modifying the constitutional text. In fact, it offers a separate complement to the Constitution by detailing a matter which the Constitution dealt with only generically.

4.3. Amendments to the Constitution

The Constitution may be totally or partially amended.

Amendments to the Constitution consist of changes to the constitutional text, of a large or small scope, making additions, deletions, or even alterations.

Since 2020, there have been two important processes to create a new constitution and replace the 1980 text, which was rejected by a majority of people in September 2022 and December 2023.

The Constitution is now not a “rigid” one, based on the current proceedings to modify.

The Constitution may be amended on the proposal of any members of the Chamber of Deputies or of the Senate or the President of the Republic, depending on the matter. Such amendments must respect certain fundamental principles: direct, secret, universal, and periodic vote; individual rights and guarantees; and separation of powers.

Approval requires four-sevenths of the votes in each chamber or two-thirds of the votes of the respective members if the President exercises veto (Law N° 21.535, January 2023).

Code Terminology: In some matters, like labor, there exist several laws. Sometimes, the Congress decides to refund all the laws in a new code. For that purpose, Congress grants to the President the faculty to refund and unify the several laws in one code but without modifying the articles. Today, the new Labour Code (“Código del Trabajo”) is a mix of several laws and it is referred to as “Labour Code” refunded (now) by the Law number (Ley 21690 of August 24, 2024) (the last one). Normally, the same text contains the correct reference; for example, the Labour Code says: DFL Nº 1, from 1994, “Establish a refunded, coordinated and systematized text of Labour Code…” Then, it has be referred to as “The Labour Code, in his text established for DFL Nº 1, from 1994.”

In other cases, there exists only one text: the same law where the legislator can add some changes, maintaining the number of the law. This is the case for the Tax Law; it has several changes, but, in fact, it has maintained its number since 1974. Again, normally the beginning of the law gives the key: it says: Tax Law, “Decree Law Nº 830, from 1974,” currently/up to date to 2018.

4.3.1. Regarding the Criminal Procedure Reform in Chile

Within the process of modernization of the public institutions, the Chilean governments of the last decade considered it extremely important to implement a radical reform to the criminal legal system described above, enacting several laws since 1997. Starting in the year 2000, the so called “Reforma Procesal Penal” (the “Reform”) has been gradually implemented within the different regions of Chile, now being applied throughout the country.

The main purpose of the Reform–the most transcendental reform experienced by the Chilean criminal regulation in its whole history–is to incorporate the respect of human rights and international standards regarding the justice administration programs performed in Chile. The Reform aims to shape such programs pursuant to the social, political, economic, and cultural development experienced by Chilean society in the last decades. The core element of this new system, which is an accusatory one instead of the former inquisitive system, is that the different stages of the process will be handled by different institutions, to guarantee the impartiality of the judges, the efficiency of the investigation, and the transparency of the whole process.

Additionally, the new procedure has limited deadlines vis-à-vis the former one. The process can last no longer than a few months, instead of the three or more years which were the average extent of any process within the former system. This benefits important aspects of the criminal procedure, such as the quality of the evidence and witnesses presented by the prosecutor and the defender, and the right of the prosecuted to remain free or to be set free if there are no legal grounds to find him or her guilty within a short period of time.

The main institutions involved in the Reform are:

  • The Public Ministry (“Ministerio Publico”), an autonomous position (independent from the government) that investigates the crime and prosecutes the individual against whom are raised the charges. This institution is hierarchically organized under the Attorney General (“Fiscal Nacional”), who commands the other attorneys (“fiscales”) at a national level;
  • The Criminal Public Defender (“Defensoria Penal Publica”), in charge of providing free legal defense to the prosecuted persons. The main principle ruling the actions of this organism is to provide professionalized services to all who are being prosecuted for a crime no matter whether they have economic possibilities to hire a private defender or not;
  • The Supervisory Judge (“Juez de Garantía”), a judge specialized in criminal law, who, during the investigation, oversees overseeing the due process, the protection of the rights of all the people involved in the process (prosecuted, victims, witnesses, etc.), and of resolving the conflicts that may arise between the parties.

After the investigation period, provided it has not been finished by a brief or summarized procedure (measures stated to clear the work of the courts), the trial itself takes place. During the trial, which is developed in a public and oral session, the prosecutor and the defender intervene. The parties present their respective evidence, arguments, and requirements before a criminal court comprised of three judges, who until such moment were not familiar with the case.

The most remarkable improvement of the Reform is that it applies important principles of the due process of law, such as the impartiality, the transparency, the immediate appreciation of the evidence by the court, the quickness of the procedure, the efficiency in managing the resources available, the due defense of the prosecuted, the protection that the State grants to witnesses and victims, and the special attention that the State provides to the latter helping them to overcome the consequences of the crime.

5. The Court System

The judiciary constitutes an autonomous and independent branch of government not subject to any other. The principle of jurisdictional unity is the basis of the organization and operation of the tribunals. The exercise of jurisdictional power in any type of process passing judgments and having judgments executed belongs exclusively to the courts and tribunals as determined by the laws, according to the norms on the competence and procedure which they establish.

The Chilean judicial system is historically divided into three levels: the Supreme Court, Courts of Appeals, and tribunal of first instance (or lower level). See more at the “Ministerio de Justicia y DDHH”.

At the top of the judiciary courts, there is a Supreme Court, or “Corte Suprema,” with twenty-one judges who are appointed by the President of the Republic pending approval of the Senate and who are selected from a list of five judges made by a current member of Supreme Court. The Supreme Court has the administrative and regulatory control of all judges.

There are seventeen courts of appeals and a lot of ordinary judges (the first level), divided into civil and criminal matters, family, and labor.

There are also judges in taxation matters at the first level (Tribunal Tributario y Aduanero).

5.1. Public Prosecutor

The Public Prosecutor (“Ministerio Público”) is an autonomous and hierarchical organization led by “Fiscal Nacional,” who is in charge of representing the peoples’ interests and prosecuting crimes.

5.2. Constitutional Court

The Constitutional Court (“Tribunal Constitucional”) oversees the constitutional review of the laws. It must review statutes before they are enacted (in abstracto control). This authority must declare a law or an act with the force of law inapplicable or unconstitutional. In the first case, the norm ceases to have effect but only in the specific case where it is declared. In the second case, the norm ceases to have effect in general terms.

The Constitutional Court consists of ten members: three members appointed by the Supreme Court, three members appointed by the President, and the last four chosen by the Senate–two appointed by Senate solely and two chosen by the Senate from a Chamber of Deputies proposal.

5.3. Electoral Court

The Electoral Court (“Tribunal Calificador de Elecciones”) has the control (scrutiny and clarification) of national elections (President of the Republic, National Congress, and Municipalities). It consists of five members appointed by the Supreme Court.

5.4. Contraloría General de la República

The Contraloría General de le República is an autonomous entity of technical nature and is part of the executive branch. It oversees the control of the legal aspects, management, and auditing of all the activities of the centralized and decentralized civil service, whatever its forms of organization may be, as well as of other powers granted by law. It must take part in the approval or rejection of the revenue and investment accounts of public funds.

5.5. Banco Central

The Central Bank of Chile is an autonomous entity of technical nature created in accordance with constitutional provisions, has full legal capacity, possesses its own assets, and has an indefinite duration. The Bank shall, with regard to its duties and authority, be governed exclusively by the provisions of The Central Bank of Chile Law, and it shall not be bound for any legal purposes, by provisions present or future, general or special, enacted for the public sector. The Bank shall have as its purpose to look after the stability of the currency and the normal functioning of the internal and external payment systems. The authority of the Bank, for these purposes, shall include that of regulating the amount of currency and credit in circulation, the performance of credit transactions and foreign exchange, as well as the issuance of regulatory provisions regarding monetary, credit, financing, and foreign exchange matters.

6. Administrative Organization

Chile is divided into several administrative levels. The most important are: “Región” (sixteen plus the metropolitan area or “Región Metropolitana” where you can find the capital, Santiago), “Provincia”, and “Comuna.” Chile also territorially has islands like Easter Island (“Isla de Pascua”) and “Juan Fernandez”), collectively named as “Territorio Insular,” as well as Antarctica territory.

7. Information Sources

Chilean legislation is officially published online only in the “Diario Oficial” (official gazette).

It has a legal duty to publish the state official bulletin. The public portal Biblioteca del Congreso Nacional offers an updated, free of charge, and practical way to access Chilean legislation (in Spanish), while you can access jurisprudence in the public portal of judiciary power who also has its own site.

The collected texts of the legislation in force are also available in private editions of “Codes.” Law topics are shared by several editors, like Editorial Jurídica de Chile and Thompson Reuters. You can get pay access to a private database in Thompson Reuters.

7.1. English Translations

English translations are scarce. Some organizations like the Internal Revenue Service offer some help on tax matters in English.
