How do constitutional limits prevent power from becoming concentrated in one ruler or group?

Constitutional limits prevent the concentration of power by establishing a framework that divides authority and mandates accountability, thereby curbing the potential for arbitrary rule. These mechanisms are essential for maintaining liberty and ensuring that no single individual or group can govern with absolute discretion.12

Key methods used to prevent the concentration of power include:

• Separation of Powers: By dividing governmental functions among independent branches—typically the legislative, executive, and judicial—constitutions ensure that the making, executing, and interpreting of laws require the sanction of different bodies, preventing any one branch from dominating the others.3
• Checks and Balances: This principle induces branches to share power by granting them the authority to restrain one another. Examples include the presidential veto, legislative impeachment, and judicial review, which allows courts to examine the constitutionality of government actions.1
• Rule of Law: This norm ensures that all citizens and officials are subject to the law, preventing rulers from acting above legal constraints.4
• Federalism: Dividing power between central and local governments further disperses authority, providing additional layers of restraint.5

These structures collectively protect against tyranny by ensuring that power is exercised through established, transparent, and accountable processes.12
