The Rio Branco Institute (Portuguese: Instituto Rio Branco; Abbreviation: IRBr) is Brazil's diplomatic graduate school, internationally recognized as one of the best diplomatic academies in the world. It is the oldest government school in the country and the third oldest diplomatic training institution on the planet, located in Brasília. The institute was created on April 18, 1945, as part of the centennial celebration of the birth of the Baron of Rio Branco, the greatest and most important diplomat in the history of Brazil. The IRBr is run by the Ministry of External Relations of Brazil.Graduation from the IRBr is the only possible entrance point into the diplomatic career in Brazil.

The Ministry of Foreign Affairs (MRE; Portuguese: Ministério das Relações Exteriores; literally: Ministry of External Relations) conducts Brazil's foreign relations with other countries. It is commonly referred to in Brazilian media and diplomatic jargon as Itamaraty, after the palace which houses the ministry (originally in Rio de Janeiro, and currently in a second location which also bears this name in Brasília). Since 1 January 2023, the minister responsible is Mauro Vieira. The Ministry of Foreign Affairs operates the Rio Branco Institute and the Alexandre de Gusmão Foundation.

The Itamaraty Palace (Portuguese: Palácio Itamaraty), also known as the Palace of the Arches (Palácio dos Arcos), is the headquarters of the Ministry of Foreign Affairs of Brazil. It is located in the national capital of Brasília. The building was designed by architect Oscar Niemeyer and inaugurated on April 21, 1970. It is located to the east of the National Congress building along the Ministries Esplanade, near the Praça dos Três Poderes (Three Powers Plaza). In Brazil, Itamaraty is generally used as a metonymy for the Ministry of Foreign Affairs. The name stems from that of the palace in Rio de Janeiro which was the headquarters of the ministry before the Brazilian capital and government were moved to Brasília.

The Superior Court of Justice (Portuguese: Superior Tribunal de Justiça, also known as STJ, IPA: [ˌɛsiteˈʒɔtɐ]) is the highest appellate court in Brazil for non-constitutional questions of federal law. The STJ also has original jurisdiction over some cases. Its competence is described in Article 105 of the Brazilian Constitution of 1988. A Special Appeal (in Portuguese, Recurso Especial) can be made to this court when a judgement of a court of second instance offends a federal statutory provision or when second instance courts have issued different interpretations of the same federal statute. By rule, the STJ decides only questions of law, not any questions of fact and the probatory elements on the case, about which the Second Instance Courts give the last word. As in other superior courts in Brazil, STJ's justices are called "ministers" (Portuguese: ministros), not to be confused with ministers from the executive branch.

The Tribunal de Contas da União (Federal Court of Accounts, often referred to as TCU) is the Brazilian federal audit office. It is tasked with assisting Congress in its Constitutional incumbency to exercise external audit over the Executive Branch. Its members, called ministers, are appointed by the National Congress and the President of Brazil. The TCU employs a highly qualified body of civil servants to prevent, investigate and sanction corruption and malpractice of public funds, with national jurisdiction. The Tribunal was created in 1891, although its origins are traced back to the Royal Treasury (Erário Régio), established in 1808 by King John VI. It is, therefore, one of the world's earlier institutions charged with national government accountability. Today, the TCU cooperates with the Comptroller-General of the Union (CGU), which centralizes federal executive internal audit. The Tribunal's work is scrutinized by the Public Ministry. In 1959 it hosted III INCOSAI, the third triennial convention of the International Organization of Supreme Audit Institutions.The work executed by the TCU in 2011 produced savings of 14 billion reais (US$7.44 billion) to the Brazilian taxpayer. For each real spent by the court to avert corruption and wasteful spending, 10.5 reais were saved.

The National Congress Palace (Portuguese: Palácio do Congresso Nacional) is a building in Brasilia, Brazil that serves as the meeting place of the Brazilian national legislature, the National Congress of Brazil. It was built in 1960.

The National Congress of Brazil (Portuguese: Congresso Nacional do Brasil) is the legislative body of Brazil's federal government. Unlike the state legislative assemblies and municipal chambers, the Congress is bicameral, composed of the Federal Senate (the upper house) and the Chamber of Deputies (the lower house). The Congress meets annually in Brasília from 2 February to 22 December, with a mid-term break taking place between 17 July and 1 August.The Senate represents the 26 states and the Federal District. Each state and the Federal District has a representation of three senators, who are elected by popular ballot for a term of eight years. Every four years, renewal of either one third or two-thirds of the Senate (and of the delegations of the States and the Federal District) takes place. The Chamber of Deputies represents the people of each state, and its members are elected for a four-year term by a system of proportional representation. Seats are allotted proportionally according to each state's population, with each state eligible for a minimum of 8 seats (least populous) and a maximum of 70 seats (most populous). Unlike the Senate, the whole of the Chamber of Deputies is renewed every four years.Until recently it was common for politicians to switch parties and the proportion of congressional seats held by each party would often change. Seats belong to the parties and not to the politicians; one can only change parties and retain his or her seat in a very limited set of cases. Politicians who abandon the party for which they were elected now face the loss of their congressional seat. Each house of the Brazilian Congress elects its president and the other members of its directing board from among its members. The President of the Senate is ex officio the President of the National Congress, and in that capacity summons and presides over joint sessions, as well as over the joint services of both houses. The President of the Chamber is second in the presidential line of succession while the President of the Senate (and of Congress) is third.

The Chamber of Deputies (Portuguese: Câmara dos Deputados) is a federal legislative body and the lower house of the National Congress of Brazil. The chamber comprises 513 deputies, who are elected by proportional representation to serve four-year terms. The current President of the Chamber is the Deputy Arthur Lira (PP-AL), who was elected on 1 February 2021.

The Federal Senate (Portuguese: Senado Federal) is the upper house of the National Congress of Brazil. When created under the Imperial Constitution in 1824, it was based on the House of Lords of the British Parliament, but since the Proclamation of the Republic in 1889 and under the first republican Constitution the Federal Senate has resembled the United States Senate. The current president of the Federal Senate is Rodrigo Pacheco, a member of the Social Democratic Party from Minas Gerais. He was elected in February 2021 for a two-year term and re-elected in February 2023 for another two-year term.

The Apostolic Nunciature to the Republic of Brazil is an ecclesiastical office of the Catholic Church in Brazil. It is a diplomatic post of the Holy See, whose representative is called the Apostolic Nuncio with the rank of an ambassador.

The Superior Electoral Court (Brazilian Portuguese: Tribunal Superior Eleitoral, TSE) is the highest body of the Brazilian Electoral Justice, which also comprises one Regional Electoral Court (Brazilian Portuguese: Tribunal Regional Eleitoral, TRE) in each of the 26 states and the Federal District of the country, as determined by the Article 118 of the Constitution of Brazil.

The Supreme Federal Court (Portuguese: Supremo Tribunal Federal, [suˈpɾẽmu tɾibuˈnaw fedeˈɾaw], abbreviated STF) is the supreme court (court of last resort) of Brazil, serving primarily as the Constitutional Court of the country. It is the highest court of law in Brazil for constitutional issues and its rulings cannot be appealed. On cases involving exclusively non-constitutional issues, regarding federal laws, the highest court is, by rule, the Superior Court of Justice.
