Chamber of Deputies plenary during a session vote

The Chamber of Deputies plenary during a voting session, with green chairs and electronic panel, symbol of Brazilian democracy.

About this subject

The Chamber of Deputies plenary is the main deliberation space of the Brazilian federal legislative branch, located in the National Congress Palace in Brasília. Designed by Oscar Niemeyer, the plenary accommodates 513 federal deputies, elected by proportional vote for four-year terms. During voting sessions, parliamentarians occupy the green chairs arranged in a semicircle, while the Chamber President leads proceedings from the high table. The electronic panel in front displays voting results in real time, with green (yes), red (no), and yellow (abstention) lights.

The Chamber of Deputies represents the Brazilian people, with each state and the Federal District electing a number of deputies proportional to their population, up to a limit of 70 per federative unit. The plenary is the stage for heated debates and historic decisions, such as the approval of constitutional amendments, ordinary and complementary laws, and oversight of the Executive. Sessions are broadcast live on TV Câmara and YouTube, ensuring transparency in the legislative process.

Curiously, the plenary has undergone modernization reforms, such as the installation of the electronic voting system in 1995, which replaced the manual ballot method. The symmetric and well-lit environment during midday reflects the pursuit of balance and clarity in political debates. The modernist architecture, with its straight lines and exposed concrete, contrasts with the green-toned furniture, a color symbolizing hope and democratic renewal.
