The Câmara dos Deputados is the lower house of the National Congress of Brazil, responsible for creating and voting on federal laws. It consists of 513 deputies who are elected by the Brazilian population every four years. Each state has a varying number of representatives based on its population, ensuring that all regions have a voice in the legislative process. The Câmara dos Deputados works alongside the Senado Federal, the upper house, to discuss and approve legislation. It also plays a crucial role in overseeing the executive branch, including the actions of the President of Brazil, and can initiate impeachment proceedings if necessary.
