📌 The Senate's Three Constitutional Roles

Under Brazil's 1988 Constitution, the Senate has three core functions:

1. Legislative Function (Creating Laws)

Debates and votes on bills (including those passed by the Chamber of Deputies)

  • May propose new legislation (bills, constitutional amendments, provisional measures)

  • Has exclusive authority to:
    -Approve international financial operations
    -Confirm appointments to the Supreme Court and Central Bank

2. Oversight Function (Checking Government Power)

  • Can summon ministers for questioning

  • Launches Parliamentary Investigative Committees (CPIs)

  • Reviews the President's annual budget report

3. State Representation

  • Each of Brazil's 26 states and Federal District elects 3 senators regardless of population

  • Ensures smaller states aren't dominated by São Paulo or Minas Gerais

🏛 Daily Operations: How the Senate Works

1. Voting Sessions

  • Plenary: Major votes occur here (constitutional amendments, Supreme Court nominations)

  • Thematic Committees: Analyze bills before plenary votes (e.g., Constitution & Justice Committee)

2. Voting Agenda

  • Party leaders negotiate which bills reach the floor

  • Some votes (like impeachment trials) are conducted secretly

3. Senators' Responsibilities

  • Debate legislation in committees and plenary sessions

  • Propose amendments to existing bills

  • Investigate executive branch actions

🔍 Key Facts

  • 81 senators (3 per state + Federal District)

  • 8-year terms (with staggered elections every 4 years)

  • 2024 salary: R$41,600/month (plus office budgets)

  • Largest party: PL (15 seats), followed by PSD and MDB

⚠️ Criticisms and Challenges

  • Slow pace: Bills often languish for years

  • Patronage politics: Support traded for appointments

  • High costs: Annual operations exceed R$5 billion (including benefits)

📌 Conclusion: How Powerful Is Brazil's Senate?

Extremely. It can block Chamber-approved bills, investigate the President, and shape the judiciary. While complex, it's vital to Brazil's democracy.
