From the 1968 Referendum on the system of voting , Fine Gael urge voters to “Say NO while you still have a chance” .
There were two Referendums on that day both defeated.
The change in voting one was
To substitute for the present system of voting at Dáil elections the “straight vote” system in single-member constituencies;
To establish a Commission to determine constituencies, subject to the right of the Dáil to amend the constituencies as so determined; and
To provide that whenever the Dáil is dissolved the outgoing Ceann Comhairle may be returned, without a contest, as a second deputy for a constituency chosen by him which consists of, or includes a part of, the constituency he represented before the dissolution.
Whilst the Formation of Dail Constituencies Referendum….
The Third Amendment of the Constitution Bill, 1968, proposes that in forming Dáil constituencies, the population per deputy in any case may not be greater or less than the national average by more than one-sixth and that regard must be had to the extent and accessibility of constituencies, the need for having convenient areas of representation and the desirability of avoiding the over-lapping of county boundaries.
Both were rejected.
