The Max Planck Institute for Comparative Public Law and International Law held a new session of its Ibero-American Colloquium series entitled “The Legislative Branch Under Scrutiny. The Cases of Argentina and Peru”. The session was conducted in Spanish and focused on the study of legislative power in Latin America.

The legislative branch in Argentina

Mariana Llanos, senior researcher at the GIGA German Institute for Global and Area Studies and professor at the University of Erfurt, opened the session with a presentation on the legislative branch in Argentina. In her contribution, she examined institutional arrangements and the relationship between the legislature and other branches of government.

She then offered an overview of the main features of the Argentine case. She explained how legislative institutions operate within the political system and pointed to elements relevant for comparative analysis in the region.

The Congress of Peru

In the second presentation, Milagros Campos, professor at the Pontifical Catholic University of Peru and specialist in parliamentary affairs, addressed the functioning of the Congress of Peru. Her presentation focused on legislative practice and on recent experiences related to parliamentary work.

Drawing on her academic and professional experience, Campos examined aspects of parliamentary organization and institutional development. She also shared observations on the performance of Congress in the current political context.

Discussion and closing remarks

Following the presentations, the discussion space allowed participants to compare the cases of Argentina and Peru. During the exchange, participants identified similarities and differences between both legislative systems. The conversation highlighted the value of comparative analysis for the study of parliamentary institutions.

The session concluded with a reflection on the importance of maintaining academic dialogue on legislative power in Latin America. The Ibero-American Colloquium series was presented as a relevant space for promoting this type of exchange.
