The official order of precedence ranks the speaker of the Hellenic Parliament in the 3rd position, after the President of the Republic and the Prime Minister.

Additionally, the Speaker stands in pro tempore for the President of the Republic when the latter is abroad for a prolonged period of time, passes away, resigns, is deposed, or is hindered from performing his or her duties for any reason whatsoever.

This includes the presidents of the National Assemblies and the various legislative bodies under Governor Ioannis Kapodistrias and his successors.

The regents ignored the so-called "Hegemonic Constitution [fr]" voted by the Fifth National Assembly, and when Otto assumed full powers, he ruled as an absolute monarch.

The only "parliamentary" body was the 20-member Council of State (Συμβούλιο της Επικρατείας), but its role was purely consultative and it was strictly controlled by the King.

The Senate was abolished, and a unicameral parliament (Βουλή) of 181 members with a four-year term was proclaimed as the country's sole legislative body.

The Goudi coup of 1909 resulted in the arrival of Eleftherios Venizelos and the August 1910 elections for a Revisoniary Parliament.

On 30 September 1925, the Parliament was abolished after the 25 June coup d'état led by Theodoros Pangalos.

The fall of the junta brought about a major regime change (metapolitefsi), which included the abolition of the monarchy by referendum.
