Greek constitutional amendment of 1986

The Greek Constitutional amendment of 1986 was based on the previously increased responsibilities of the President of the Republic. Despite the fact that the "increased" responsibilities of the President of the Republic were never exercised until 1986, by virtue of their mere existence they influenced the development of political affairs from 1980 to 1985, specifically during the first co-existence of Constantine Karamanlis as President of the Republic with the government of PASOK. The responsibilities of the President of the Republic were the target of the revisionary proceedings of 1985-1986.

On March 6, 1986, pursuant to article 110 of the Constitution, which stipulates that the provisions of the Constitution are subject to revision except for those which determine the form of government as a Parliamentary Republic as well as certain other provisions, eleven articles were amended and a vote was passed transposing the text of the Constitution into demotic Greek.

Through this revision the responsibilities of the President of the Republic were curtailed to a significant extent. Despite the political and the constitutional tensions of that period, the revised Constitution of 1975/1986, which introduced a pure parliamentary governmental system, was accepted by all political powers.
