Legislatura CABA

The Legislature of Buenos Aires, also known as Legislatura CABA, is the unicameral legislative body of the Autonomous City of Buenos Aires in Argentina. Its primary function is to draft, debate, and enact local laws that govern the city’s affairs. It also reviews and approves the municipal budget, ensuring that public funds are allocated according to legislative priorities. The legislature oversees the execution of city policies and can summon municipal officials to account for their actions. Representing the residents of Buenos Aires, it provides a forum for citizen participation through public hearings and committee work. Its headquarters are located in the city centre of Buenos Aires, Argentina.

As a subnational legislative institution, the Legislature of Buenos Aires operates within the framework of Argentina’s federal system, exercising authority delegated to the city government. It distinguishes itself by focusing exclusively on the regulatory and legislative needs of one of Latin America’s largest urban centers. The body’s competencies include lawmaking, fiscal oversight, and the ability to initiate investigations into municipal administration. Structurally, it is a public entity directly accountable to the citizenry of the Autonomous City of Buenos Aires, with no private ownership or parent company. In September 2022, the legislature experienced a ransomware attack that compromised its internal operating systems and disrupted Wi‑Fi connectivity. The incident prompted immediate containment measures, collaboration with cybersecurity specialists, and notification of law enforcement, while the legislature’s website remained inaccessible during the initial recovery phase. This event highlighted the vulnerability of government institutions to cyber threats and aligned with a broader trend of ransomware targeting public sector entities across Central and South America.
