An entrenched clause is a constitutional provision designed to be harder to alter than ordinary law, or in some cases impossible to alter at all. Entrenchment can be procedural (requiring supermajorities, referendums, multiple legislative readings, or ratification by sub-national units) or substantive/absolute (declaring certain principles unamendable, often called "eternity clauses").
The mechanism serves two main functions: protecting core constitutional commitments — such as fundamental rights, federalism, or democratic structure — from transient majorities, and signaling credible commitment to citizens, minorities, and international partners.
Well-known examples include:
- Germany's Basic Law, Article 79(3) — the Ewigkeitsklausel — which forbids amendments affecting the federal structure, the participation of the Länder in legislation, and the principles laid down in Articles 1 (human dignity) and 20 (democratic and social federal state).
- Article V of the U.S. Constitution, which entrenches equal state suffrage in the Senate: no state may be deprived of its equal vote without its consent.
- France's Constitution of 1958, Article 89, which prohibits amendments altering the republican form of government.
- India's "basic structure doctrine", a judicial form of entrenchment developed in Kesavananda Bharati v. State of Kerala (1973), under which the Supreme Court holds that Parliament cannot amend the Constitution's basic structure even using the formal amendment procedure.
- South Africa's Constitution (1996), section 74, which imposes graduated supermajority thresholds depending on which provisions are being amended, with the founding values in section 1 requiring a 75% National Assembly vote.
Critics argue entrenchment can freeze outdated arrangements and create counter-majoritarian deadlock. Defenders respond that without entrenchment, constitutions offer little more protection than ordinary statutes. In comparative constitutional design, the degree and type of entrenchment is a key variable distinguishing "rigid" from "flexible" constitutions — a typology associated with James Bryce.
Example
Article 79(3) of Germany's 1949 Basic Law entrenches human dignity and the federal democratic order, barring the Bundestag from amending these principles even by supermajority.
Frequently asked questions
An eternity clause is a type of entrenched clause that is absolutely unamendable. Other entrenched clauses are merely harder to amend, requiring supermajorities or referendums but not impossible to change.
