Page "Constitution of Ireland" Paragraph 5

De Valera personally supervised the writing of the Constitution.

It was drafted initially by John Hearne, legal adviser to the Department of External Affairs ( now called the Department of Foreign Affairs ).

It was translated into Irish over a number of drafts by a group headed by Micheál Ó Gríobhtha ( assisted by Risteárd Ó Foghludha ), who worked in the Irish Department of Education.

De Valera served as his own External Affairs Minister, hence the use of the Department's Legal Advisor, with whom he had previously worked closely, as opposed to the Attorney General or someone from the Department of the President of the Executive Council.

He also received significant input from John Charles McQuaid, the Archbishop of Dublin, on religious, educational, family and social welfare issues.
