Constitution of Greece in the context of "Cabinet of Greece"

An entrenched clause or entrenchment clause of a constitution is a provision that makes certain amendments either more difficult or impossible to pass. Overriding an entrenched clause may require a supermajority, a referendum, or the consent of the minority party. 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. However, if a constitution provides for a mechanism of its own abolition or replacement, like the German Basic Law does in Article 146, this by necessity provides a "back door" for getting rid of the "eternity clause", too.

Any amendment to a constitution that would not satisfy the prerequisites enshrined in a valid entrenched clause would lead to so-called "unconstitutional constitutional law"—that is, an amendment to constitutional law text that appears constitutional by its form, albeit unconstitutional due to the procedure used to enact it or due to the content of its provisions.

The Greek royal family (Greek: Βασιλική Οικογένεια της Ελλάδος) was the ruling family of the Kingdom of Greece from 1863 to 1924 and again from 1935 to 1973. The Greek royal family is a branch of the Danish royal family, itself a cadet branch of the House of Glücksburg. The family had replaced the House of Wittelsbach that previously ruled Greece from 1832 to 1862. The first monarch was George I of Greece, the second son of King Christian IX of Denmark. The current head of the family is former Crown Prince Pavlos, who assumed the role on 10 January 2023 upon the death of his father, former King Constantine II.

With the 1974 Greek republic referendum and Article 4 of the Constitution of Greece, all family members have been stripped of their honorific titles and the associated royal status. Many family members born after 1974 still use the titles "Prince of Greece" and "Princess of Greece" to describe themselves, but such descriptions are neither conferred nor legally recognised by the Greek state as royal or noble titles. The family accepts that these terms are not royal titles, but rather personal identifiers.

The president of Greece, officially the president of the Hellenic Republic (Greek: Πρόεδρος της Ελληνικής Δημοκρατίας, romanized: Próedros tis Ellinikís Dimokratías), commonly referred to in Greek as the president of the Republic (Πρόεδρος της Δημοκρατίας, Próedros tis Dimokratías, ΠτΔ), is the head of state of Greece. The president is elected by the Hellenic Parliament; the role has been mainly ceremonial since the 1986 constitutional reform. The office was formally established by the Constitution of Greece in 1975, but has antecedents in the Second Hellenic Republic of 1924–1935 and the Greek junta in 1973–1974 which predated the transition to the current Third Hellenic Republic.
