Chamber Moves Forward With Plan for Mixed District-and-List System

Overview

• Lawmakers led by Hugo Motta are advancing a constitutional amendment to create a distrital misto that would elect roughly half of federal deputies by geographic districts and half from closed party lists.
• Domingos Neto is expected to serve as relator and party leaders are negotiating model details, but the proposal remains under active discussion rather than near final approval.
• Data from Poder360 using TSE results shows 308 of 513 deputies had at least 50% of their votes concentrated in 10 municipalities, a statistic supporters cite to justify formal district rules.
• Negotiators plan a staged rollout with no immediate change for the next election and full implementation aimed for 2034, and they are debating district maps, inclusion rules, and whether to raise the Chamber to about 520 seats to permit an even split.
• The plan faces political resistance from the PL and cautious PT leaders and raises technical and democratic concerns including unequal state representation, risks to minority representation, and potential local capture by criminal groups.
