Contrasting Governance: How the UK and Brazil Approach the Separation of Powers

Hello everyone, and welcome to our exploration of the separation of powers in the United Kingdom and Brazil. Today, we’ll dive into the key differences and similarities between these two systems, providing a comparative critique of their effectiveness in maintaining democratic integrity.

Let’s begin by understanding the UK’s approach to the separation of powers. The United Kingdom operates under a partial separation of powers, shaped by its unwritten constitution and centuries of historical evolution. Key milestones like the Magna Carta of 1215, the Bill of Rights of 1689, and the Act of Settlement of 1701 symbolize the gradual shift of authority from the monarchy to Parliament. However, a hallmark of the UK system is the overlap between the executive and legislative branches. Government ministers are often Members of Parliament, holding dual roles that challenge Montesquieu’s ideal of distinct and independent branches.

Critics, such as Rodney Brazier, argue that this overlap diminishes accountability. However, others highlight that this system fosters a dynamic interaction between the branches, which is vital for democratic governance. For instance, as noted in Support Steels Ltd v Sirs (1980), Lord Diplock affirmed that the British Constitution, despite being unwritten, firmly rests on the principle of the separation of powers. This balance ensures that Parliament makes laws while the judiciary interprets them, maintaining a democratic harmony.

Reforms such as the Constitutional Reform Act of 2005 have been pivotal in strengthening judicial independence and enhancing democracy. This Act established the UK Supreme Court, removing the judicial function from the House of Lords, and redefined the role of the Lord Chancellor, mitigating political influence over judicial appointments. As Andrew Le Sueur has noted, this reform redistributed power in a way that curbed what could previously have been described as an 'elective dictatorship,' reinforcing constitutional control over the government.

Judicial oversight in the UK is robust yet limited by the principle of parliamentary sovereignty. Landmark cases like R (Miller) v Prime Minister (2019) and M v Home Office (1994) highlight the judiciary’s critical role in checking executive overreach. In these cases, the courts demonstrated their ability to hold the government accountable for unlawful decisions, aligning with A.V. Dicey’s principle of the rule of law. Yet, the inability of UK courts to nullify legislation underscores the balance maintained to respect parliamentary supremacy while upholding democratic values.

In Brazil, we encounter a contrasting model. Brazil’s system is based on a rigid, written constitution, explicitly enshrined in Article 2 of the 1988 Federal Constitution. This article guarantees the independence and harmony of the executive, legislative, and judicial branches. Unlike the UK, Brazil’s judiciary wields significant authority, with the Supreme Federal Court empowered to declare laws unconstitutional. This was evident in cases like ADI 4.048/DF, which invalidated laws conflicting with constitutional principles.

Brazil’s embrace of judicial activism further distinguishes its legal system. Courts frequently influence public policy, especially during crises. For example, during the COVID-19 pandemic, the Federal Supreme Court (STF) played a pivotal role in regulating measures through significant decisions, such as the interpretation and application of Law 13.979/2020. This activism highlights the judiciary’s capacity to safeguard fundamental rights but also draws criticism for perceived overreach into legislative and executive functions.

While Brazil's judiciary steps in to address gaps left by other branches, this dynamic often exposes tensions between institutional powers. Moreover, Brazil’s rigid constitutional framework—rooted in detailed, codified provisions—contrasts with the UK’s flexible, unwritten constitution, which allows for a more adaptable approach to crises. This difference underscores the challenges Brazil faces in balancing judicial intervention with democratic accountability during emergencies.

Now let’s compare these systems more directly.

First, the constitutional framework. The UK’s unwritten constitution allows for adaptability but lacks the clarity and stability of Brazil’s codified document. Meanwhile, Brazil’s rigid constitution ensures stability but can impede swift responses during crises.

Second, judicial authority. UK courts prioritize parliamentary sovereignty, limiting their ability to nullify laws. In contrast, Brazil’s courts, empowered by constitutional supremacy, can invalidate legislation, offering a more direct check on legislative and executive powers.

Third, checks and balances. The UK relies on conventions and political accountability, highlighted by debates over “Henry VIII powers” in the EU (Withdrawal) Act of 2018. Brazil, however, formalizes checks and balances through judicial review, ensuring greater oversight of government actions.

Finally, historical context. The UK’s system reflects centuries of gradual evolution, accommodating flexibility and tradition. In contrast, Brazil’s constitution emerged from a definitive break with military rule - Brazil's 1988 Constitution was enacted following the end of a military dictatorship (1964–1985) -, emphasizing robust institutional safeguards to prevent authoritarianism.

In Brazil, some federal deputies and a segment of the local conservative press have increasingly criticised judicial activism, labelling it as an overreach of authority. They argue that this so-called "protagonismo excessivo" (excessive protagonism) by the judiciary is paving the way for what they term a "ditadura da toga" (dictatorship of the robe). These critiques highlight a broader debate about the judiciary’s role in a democratic society and whether it is acting within the bounds of its constitutional mandate or encroaching on the roles of other branches of government. Despite these criticisms and concerns about occasional overreach, Brazil's judiciary remains a cornerstone of its democratic framework.

In conclusion, the separation of powers is foundational to both the UK and Brazil, though applied differently. The UK’s model balances tradition and flexibility, while Brazil relies on constitutional rigidity and judicial authority. Despite their differences, both systems effectively prevent authoritarianism and promote accountability. Their unique paths, shaped by history and distinct challenges, ultimately lead to the same democratic goals: liberty, justice, and the rule of law.

Thank you for joining me in this comparative journey. Remember, diverse systems can achieve shared democratic ideals through unique approaches.
