A report on Entrenched clause, Constitution of the Czech Republic and Constitution

An entrenched clause or entrenchment clause of a basic law or constitution is a provision that makes certain amendments either more difficult or impossible to pass, making such amendments invalid.

The term eternity clause is used in a similar manner in the constitutions of Brazil, the Czech Republic, Germany, Greece, India, Iran, Italy, Morocco, Norway, and Turkey, but specifically applies to an entrenched clause that can never be overridden.

The constitution is a constitutional act, and together with other constitutional acts constitutes the so-called constitutional order of the Czech Republic, or the constitution (with a small c).

With reference to the provision of the article 39, paragraph 4 of the Constitution, which states that "for the enactment of a constitutional act, 3/5 of all deputies must agree, and 3/5 of senators present", changing the constitution is a more difficult procedure than changing an ordinary statute, making it an entrenched constitution in the typology of constitutions.

Constitutions may also provide that their most basic principles can never be abolished, even by amendment.

The term eternity clause is used in a similar manner in the constitutions of the Czech Republic, Germany, Turkey, Greece, Italy, Morocco, the Islamic Republic of Iran, Brazil and Norway.
