Milei will return to Spain for the Ibero-American Summit two weeks after his last visit

There is no single parliamentary procedure to approve the agreements of an Ibero-American Summit. The route depends on their nature: a political declaration does not require the same intervention as a treaty that legally binds Spain. Parliamentary support for the summit's conclusions should also not be confused with the authorization necessary to assume certain international commitments.

1. Declarations and political commitments

If the agreement contains declarations of intent or political, technical, or logistical commitments, without creating international obligations, it does not require the parliamentary authorization typical of treaties. This distinction is reflected in Judgment 228/2016, when explaining non-normative international agreements.

The Parliament can debate its results and express support, rejection, or recommendations through various means:

• Government appearances: allow for informing and answering questions, but do not by themselves constitute approval.
• Government communications: can be debated in the Plenary or in committee. At the end, groups have thirty minutes to present resolution proposals, which are debated and voted on.
• Non-legislative motions: groups present resolution proposals that the Board admits and refers to the Plenary or the competent committee. They are debated, may receive amendments, and are voted on.

These resolutions express a political position but do not replace treaty authorization. As a general rule, they are approved by simple majority, with the required quorum. The described routes are regulated in articles 193 to 203 of the Congress Regulations.

2. When the agreement requires authorization

If the instrument constitutes a treaty covered by article 94.1 of the Constitution, the Cortes must authorize it before Spain gives its consent to be bound. For example, this requirement applies to treaties that involve financial obligations for the Public Treasury. What matters is the legal content of the instrument, not that it was adopted at a summit.

In the Congress, the procedure of articles 155 and 156 follows these steps:

1. Government request: submits the Council of Ministers' agreement, the treaty text, a justificatory memorandum, and any reservations or declarations it intends to make.
2. Presentation: must occur within ninety days following the Council of Ministers' agreement; exceptionally, it can be extended up to one hundred eighty days, justifying the delay with documentation.
3. Parliamentary processing: follows the ordinary legislative procedure, with special features. Denial or postponement of authorization and changes related to reservations or declarations may be proposed. The Congress must decide within sixty days. These deadlines are calculated according to parliamentary rules on working days and session periods.
4. Senate intervention: authorization also requires its pronouncement. If there are discrepancies, a mixed commission proposes a text to both chambers; if no agreement is reached, the Congress decides by absolute majority.

3. Special cases and execution

If the treaty assigns an international organization the exercise of powers derived from the Constitution, an organic law of authorization is required. For treaties under article 94.2, the route is to inform the chambers; in the Congress, the Foreign Affairs Committee is notified.

If doubts about constitutionality arise, a prior ruling from the Constitutional Court may be requested, suspending the processing. Additionally, the laws necessary to execute the agreement are processed separately: neither a political resolution nor a decree-law replaces the required international authorization, as explained in Judgment 155/2005.

The President of the Argentine Nation is, according to the Argentine Constitution, the highest authority of the Executive Power and simultaneously concentrates the functions of head of State, head of Government, and supreme chief of the Nation and the Armed Forces. Their powers and functions are mainly regulated in articles 87 to 107 of the National Constitution (amended text of 1994).

Constitutional position and nature of the office

• Head of State and Government: represents the Nation internally and internationally, embodies the unity of the country, and leads the general policy of the federal government.
• Holder of the Executive Power: the Executive Power of the Nation is exercised by a citizen with the title of “President of the Argentine Nation” (art. 87).
• Chief of the Armed Forces: is the commander-in-chief of all the nation's armed forces (art. 99, inc. 12).

Relations with the Legislative Power

• Legislative initiative power: can send bill proposals to the National Congress on any matter of federal competence.
• Promulgation and veto of laws: must promulgate laws passed by Congress or, if applicable, veto them totally or partially. The veto must be motivated and can be overturned by a new vote of Congress with the required majority (total or partial veto, art. 99 inc. 3).
• Calling extraordinary sessions: can convene Congress to extraordinary sessions and extend the ordinary session period when deemed necessary (art. 99, inc. 9).
• Reports before Congress: at the start of ordinary sessions, the president must report on the state of the Nation, the reforms promised by the Constitution, and recommend measures deemed necessary (traditional “message to Congress”).

Regulatory power and administrative function

• Regulating laws: issues necessary regulations for the execution of national laws, without altering their spirit or letter (art. 99, inc. 2).
• Direction of public administration: appoints and removes officials of the central administration, according to the Constitution and laws, and exercises political leadership of the cabinet of ministers.
• Appointment and removal of ministers: appoints the Chief of the Cabinet of Ministers and other ministers, and can freely remove them (art. 99, inc. 7). The Chief of Cabinet has own powers and also answers to Congress, but the president remains the head of the Executive.

Foreign policy and defense

• International relations: directs the Nation's foreign relations, concludes and signs treaties, concordats, and other conventions, which are subject to Congress approval (art. 99, inc. 11).
• Diplomatic representation: appoints and removes ambassadors, plenipotentiary ministers, and chargés d'affaires, with Senate agreement.
• Armed Forces: commands the armed forces, disposes of them, and organizes their distribution, always subject to the Constitution and laws (art. 99, inc. 12). Cannot declare war or sign peace without Congress authorization, except in cases of immediate aggression where defensive force may be used.

Appointments and Judicial Power

• Supreme Court and lower court judges: proposes candidates to the Supreme Court and federal lower courts, whose appointments require Senate agreement (art. 99, inc. 4).
• Public Ministry and other bodies: intervenes in the appointment of other high officials (e.g., prosecutors and control bodies), under terms set by the Constitution and laws.
• Pardon and commutation of sentences: can pardon or commute sentences for federal crimes, except in cases of impeachment and regarding officials subject to that procedure (art. 99, inc. 5).

Special normative powers

• Decrees of necessity and urgency (DNU): in exceptional circumstances where it is impossible to follow the ordinary law sanctioning procedure and the matters are not prohibited (criminal, tax, electoral, or political parties), the president can issue DNUs with the force of law. These must be submitted to a Bicameral Commission and then to the plenary of both Chambers for approval or rejection, according to the procedure established after the 1994 reform.
• Federal intervention of provinces: can request Congress to federally intervene a province when constitutional causes exist; in exceptional cases can decree it while Congress is not in session, provisionally and subject to later approval.
• Budget and public finances: the Executive Power prepares and presents the general budget bill of the national administration, and manages State resources and expenses according to the law approved by Congress.

Political and legal responsibility

The president is politically responsible before Congress and can be subjected to impeachment for poor performance, crimes in office, or common crimes. In that case, the Chamber of Deputies accuses and the Senate judges. Outside this mechanism, they cannot be held responsible for official opinions, although they can for crimes committed under common law.

In summary, the Argentine Constitution establishes a strong presidency, with broad executive powers, limited normative faculties, and decisive functions in foreign policy, defense, key appointments, and general State leadership, balanced by Congress control, the Judiciary, and the impeachment mechanism.

For a Brazilian citizen passing through Argentina in international transit (that is, using Argentina as a connecting country to a third State), the legal requirements combine, on one hand, the general Argentine immigration rules and, on the other, the specific rules of airlines and the countries of origin and destination. Below is a guiding outline; it is essential to always confirm with official channels (Argentine consulate and airline) because conditions may change.

1. General situation of Brazilians regarding Argentina

In general terms, Brazilian citizens are exempt from tourist visa to enter Argentina for short stays (usually up to 90 days). In transit, the same rules practically apply, with two different scenarios:

• Transit “in connection” without entering Argentine territory: you remain in the international zone of the airport and do not undergo Argentine immigration control. In this case, the essential thing is to meet the requirements of the final destination country and the airline.
• Transit with entry into Argentina: for example, because you have a long layover, change airports, or leave to the city. Here, the requirements for entry as a visitor to Argentina apply.

2. Typical requirements to enter Argentina in transit

If you need to pass through Argentine immigration control during transit, the following are usually required:

• Valid travel document: valid Brazilian passport. In many cases, due to MERCOSUR agreements, the Brazilian national identity document may be accepted, but for international transit with third countries it is usually safer to travel with a passport.
• Ticket for continuation of the trip: proof that you are in transit to a third country (confirmed reservation, with date and flight departing from Argentina).
• Compatibility with the destination country's rules: the country you are heading to may require a visa or specific documents (e.g., electronic visa, travel authorization, etc.). Argentine immigration may deny entry if it sees you do not meet the final destination requirements.
• Brief duration of stay in Argentina: although the maximum for a tourist visit is usually up to 90 days, in transit it is expected that the stay is consistent with the connection (a few hours or, at most, a few days).
• Sufficient economic means: it is common to be required to prove funds appropriate to the length of stay (cash, cards, statements, etc.).
• Proof of accommodation (if you are leaving the airport): hotel reservation, address where you will stay, or proof of extended layover.
• Absence of entry prohibitions: not being subject to current prohibitions or migration alerts in Argentina.
• Health requirements: at certain times there may be health requirements (vaccination certificates, health forms, medical insurance with minimum coverage, etc.), especially after pandemics or specific outbreaks. These conditions are changeable and should be verified shortly before travel.

3. Requirements for exiting Argentina in transit

For departure from Argentina towards the final destination country, the requirements focus on:

• Respecting the authorized stay period: if you entered Argentina, your passport (or electronic record) will show a maximum period. Leaving after that date may generate fines or future entry problems.
• Valid passport and visas for the country you are traveling to next. Argentine migration police and the airline check that you are authorized to board to that destination.
• Entry card or registration (if issued): in cases where an entry receipt is given, you must present it upon exit to close the migration record.
• Compliance with customs regulations: declaration of currency above certain limits, goods subject to control, etc. This affects both exit from Argentina and entry into the destination country.

4. Other aspects to consider

• Minors: if the Brazilian traveler is a minor, authorization from parents or guardians may be required both when leaving Brazil and when passing through Argentina. Formalities are usually strict (notarial documents, apostilles, etc.).
• Travel insurance: not always legally mandatory, but many countries recommend or require insurance with minimum coverage for medical expenses and repatriation. It is especially advisable for long transits.
• Coordination with the airline: some airlines impose additional requirements for transit passengers (minimum connection times, airport changes, checked luggage to final destination or not, etc.). If you change airlines in Argentina, it is common that you must exit and re-enter the boarding area, passing through immigration.

In summary, a Brazilian citizen can usually transit through Argentina without a visa, but must have a valid passport, ticket for departure to the third country, compliance with the final destination requirements, and respect for the stay periods if entering Argentine territory. Since regulations and health or visa requirements may change, it is essential to always confirm information at the Argentine Consulate or Embassy and with the airline before traveling.
