James Dillon (1902-86) was the sun of John Dillon, the last leader of the pre-WW1 Irish Parliamentary Party, and played a key role in founding Fine Gael, but left or was expelled from that party in 1942 owing to its support for neutrality in WW2 and then sat in the Dáil as an independent. He rejoined Fine Gael in 1953, and became its leader in 1959-65, but resigned as party leader after narrowly failing to be elected Taoiseach. He was minister for agriculture 1948-51 and 1954-57.

"If the Taoiseach agrees with me that his approach to the science of linguistics and etymology in setting up a body of civil servants to prepare the litriú is, to say the least, revolutionary, will he not think it desirable to establish a standing commission, analogous to that established by the Academie Francaise, to supervise the spelling and etymology of our own language before whom representations may be laid by interested parties, from time to time, with a view to having its work reviewed and improved if opportunity offers? Surely no valid objection could be made to that course and it would meet the views of persons, who are scarce enough in this country, God knows, who love the language for the language's sake and not for what they hope to get out of it."
"The Taoiseach has got what he wants—the litriú. Is it not reasonable to ask on behalf of those others who love the language—the Taoiseach is not the only person who loves it—that some body of scholars, as distinguished from zealous and public-spirited servants, should be set up to whom those persons can make their submissions with a view to preserving the integrity of the language they love rather than subserving the general policy of the Government in respect of the language of the country. There is surely an academic, a linguistic and an etymological side to this which appeals deeply to scholars who have devoted their whole lives to the language."
"If you cut the linguistic roots of the language, the language will die."
The Taoiseach gave some bureaucratic reply - basically the issue was being handled in house by the civil service and wider discussion was not be permitted...
