1.2 - Constitutional principles and limited government

Federalism as a principle

A constitutional principle is a fundamental idea that helps explain how the system is organised. Federalism concerns the territorial distribution of authority, while separation of powers concerns different functions of government. The two divide power along different dimensions.

Americans elect a president and Congress for the national government, but also governors and legislatures for their states. State authority is constitutionally grounded rather than simply delegated by the president. The Tenth Amendment reserves powers not given to the United States, or forbidden to the states, to the states or the people. However, Article VI makes the Constitution and constitutionally valid federal law superior to conflicting state law. Federalism combines state autonomy with a national legal order; it does not mean that states can disregard any federal decision they dislike. See the Tenth Amendment and Supremacy Clause.

Dispersed authority allows policy to reflect different communities and gives citizens more than one place to seek political change. A campaign unsuccessful nationally may influence a state government. This can restrain concentrated power. Yet citizens may face different services and legal rules according to where they live, while overlapping responsibilities can obscure accountability. If a policy fails, each level may blame the other.

The test of effectiveness depends on the purpose. Diversity may demonstrate responsiveness to different state electorates, but it may undermine equal national standards. The next lesson investigates the specific powers and financial relationships behind this tension.

Separate branches, shared powers

Separation of powers prevents the same institution from making, executing and adjudicating every law. Congress legislates, the president leads the executive, and federal courts decide cases. Their different personnel and mandates help them act independently.

The president does not sit as a member of Congress. Article I bars someone holding a federal office from simultaneously serving in either congressional chamber. Federal judges serve during good behaviour, with constitutional salary protection. These arrangements reduce direct executive control of the legislature and judiciary. The rules are in Article I, Section 6 and Article III, Section 1.

Independence is not isolation. The Senate participates in appointments to executive and judicial offices; the president participates in lawmaking through the veto. Divided functions and shared powers operate together. It is more accurate to explain which power is shared than to say the branches are completely separate.

If you sit in 2027: Issue 3's glossary calls the legislature, executive and judiciary the three key “bodies”; Issue 4 calls them “branches”. The same principle of separate powers and personnel is taught here. Buildings alone do not establish institutional independence.

Separation can improve scrutiny because one branch need not automatically follow another's wishes. However, institutions can have conflicting claims to democratic authority: a president and congressional majority may both claim to represent voters. Where they disagree, a policy can stall even though each institution has a legitimate mandate. This is one reason constitutional design can restrain arbitrary action while making coordinated action difficult.

Checks and their effectiveness

Checks and balances are mechanisms through which one branch can limit or influence another. A check is a power that exists; its effectiveness concerns whether and how that power is used.
