Questions: Division of Government into Branches

Question 1

A country adopts a new constitution formally establishing three separate branches of government with distinct functions. A political analyst concludes that power is now effectively divided and no single actor can dominate. What critical factor does this conclusion overlook?

• A. The constitution does not specify which branch is most powerful
• B. Formal separation is not self-enforcing — branches must be willing and able to check each other, courts must be independent, and actors must accept institutional limits as legitimate
• C. Three branches is insufficient — at least five are needed for effective checks
• D. The constitution should have been ratified by referendum to be legitimate

Answer: (B)

The core insight of this topic: the formal division of branches creates the possibility of checks and balances but does not guarantee them. A legislature that rubber-stamps the executive, a judiciary controlled by the ruling party, or an executive that manipulates appointments and budgets of nominally independent branches can hollow out formal separation entirely. Constitutional text is a starting point, not a conclusion. Effective separation requires political actors who treat institutional limits as legitimate constraints, not obstacles to route around.

Question 2

In a parliamentary system, how does the relationship between the executive and legislature differ from a presidential system?

• A. In both systems, the executive is separately elected and serves independently of the legislature
• B. In a parliamentary system, the executive (prime minister and cabinet) is drawn from and accountable to the legislature, and can be removed by a vote of no confidence
• C. In a parliamentary system, the executive has more power because it controls the legislative agenda
• D. Parliamentary systems always have weaker judiciaries than presidential systems

Answer: (B)

The defining feature of parliamentary systems is the fusion of executive and legislative power: the prime minister and cabinet govern only as long as they retain parliamentary confidence. They can be removed by a vote of no confidence without impeachment. This is a fundamentally different accountability mechanism from a presidential system, where the executive is separately elected for a fixed term and can only be removed through impeachment (a much higher bar). Parliamentary systems also typically allow the executive to dissolve parliament and call early elections.

Question 3

In a presidential system, the executive can be removed from office through an ordinary legislative vote if a majority opposes their policies.

• T. True
• F. False

Answer: False

In a presidential system (like the United States), the executive is directly elected for a fixed term and can only be removed through impeachment — a specific legal process requiring charges of high crimes or misdemeanors, passage by the lower chamber, and conviction by a supermajority in the upper chamber. An ordinary policy disagreement, even one supported by a legislative majority, is insufficient. This independence from routine legislative removal is a defining feature of presidential systems that distinguishes them from parliamentary ones.

Question 4

Separating government into three branches with distinct functions is, by itself, sufficient to prevent dangerous concentration of power.

• T. True
• F. False

Answer: False

Formal separation is necessary but not sufficient. The division works only when: (1) each branch is genuinely willing to check the others, (2) courts have real independence from political pressure, and (3) political actors accept institutional limits as binding. History provides many examples of governments with constitutionally separate branches where one branch effectively dominates — often because the ruling party controls the judicial appointment process, the legislative opposition is suppressed, or the military supports executive overreach. Form without substance is still tyranny.

Question 5

Why is the formal division of government into branches insufficient on its own to prevent concentration of power? What else is required?

Model answer: Formal separation creates the structure for checks but does not generate the will to use them. For branches to actually constrain each other, several conditions must hold: the judiciary must be genuinely independent (not controlled by appointments of the dominant party), the legislature must be willing to challenge executive overreach (not merely rubber-stamp it), political actors must treat constitutional limits as legitimate rather than as obstacles, and there must be sufficient civil society and electoral accountability to punish actors who violate norms. Without these conditions, the form of separation exists without the substance.

Montesquieu's argument was structural — better institutions, not better rulers. But institutions are operated by people, and people can undermine institutions while maintaining their formal existence. The key distinction is between de jure separation (what the constitution says) and de facto separation (who actually controls outcomes). This is why the study of actual checks and balances, judicial independence, and institutional design details matters — constitutional text is only the starting point.
