How does constitutional law relate to the major institutions of government?

In the context of legal education, constitutional law is defined as the branch of law that governs the major organs of state. It establishes the framework for how these institutions—typically the legislature, executive, and judiciary—are organized, how they function, and how they interact with one another.12

Constitutional law relates to these institutions through several key principles:

• Separation of Powers: Modern constitutionalism generally mandates that legislative, executive, and judicial functions be assigned to separate institutions to prevent the accumulation of power and the rise of tyranny.32
• Checks and Balances: Because a strict separation of functions is often impractical, constitutional law incorporates mechanisms—such as the presidential veto, legislative oversight, and judicial review—that allow branches to monitor and limit each other’s actions.42
• Defining Competence: Constitutional law defines the specific authority and limits of each branch, ensuring that no institution acts beyond its prescribed role.35
• Protection of Rights: By establishing a "higher law," constitutions empower the judiciary to protect individual rights against potential overreach by the legislative or executive branches.35
