I move: "That the Bill be now read a Second Time."
The Bill proposes to fix the total number of Members of the Dáil, to revise the constituencies for the election of Members to the Dáil and to prescribe the number of Members to be returned for each constituency.
In considering the background to the Bill it is necessary to refer to the provisions of Article 16.2 of the Constitution, in particular to the requirements that
(a) the ratio between the number of Members to be elected at any time for each constituency and the population of each constituency as ascertained at the last preceding census, shall, so far as it is practicable, be the same through the country, and
(b) the Oireachtas shall revise the constituencies at least once in every twelve years with due regard to changes in distribution of the population.
Twenty-two years ago the constitutional provisions relating to the revision of constituencies came before the High Court and the Supreme Court in two well-known actions. In these cases, however, the courts did not lay down what variation from the national average population per Deputy would be regarded as permissible in the formation of constituencies nor did they rule on the question of whether a revision of constituencies must take place whenever a census discloses substantial changes in the pattern of population distribution since the preceding census.
As the House is aware, the constituencies were last revised in 1980 on the basis of the population as ascertained at the census taken in April 1979. A further census was taken in April 1981 and disclosed some considerable shifts in population, particularly within the greater Dublin area. The Government considered it appropriate to put a revision of constituencies in train and, for this purpose, appointed an independent commission. The terms of reference given to the commission were the same as those given to the commission which drew up the 1980 proposals, with the additional guideline that, in view of the short time which had elapsed since the last review of constituencies, they should take account of the desirability of effecting the minimum changes.
In their report, which was laid before both Houses, the commission recommended that there should be no change in the overall membership of the Dáil or in the allocation of seats to individual constituencies. They recommended that there should be no change in the definition of the constituencies apart from the transfer of an area with a population of 10,830 from Dublin South-West to Dublin South-Central and of an area with a population of 5,783 from Dublin West to Dublin Central. This Bill proposes to implement the commission's recommendations in full.
In this regard, there are two points in particular that I would wish to make. First, the obligation to revise the constituencies is placed by the Constitution on the Oireachtas. The power of decision rests with the Oireachtas: the commission are advisory only. Secondly, it will be noted that while only four constituencies are affected by the changes, all constituencies are defined anew in the schedule. This is to ensure that the Bill gives effect to a revision of constituencies within the meaning of Article 16.2 of the Constitution, which relates to constituencies generally.
Deputies will be interested to note that, in the scheme now before the House, the percentage variations in the population-Deputy ratio range from +6.68 per cent in Louth to -7.89 per cent in Mayo East. This compares with variations in the previous revision ranging from +6.28 per cent in Carlow-Kilkenny to -6.42 per cent in Mayo East. Deputies will find a discussion of population-Deputy ratios in chapters 6, 7 and 8 of the commission's report. As I have already indicated, the courts did not set limits beyond which variations from the national average population-Deputy ratio would not be permissible.
Deputies have already received copies of the commission's report and maps have been deposited in the Oireachtas Library indicating the changes proposed in the constituencies of Dublin South-West, Dublin South-Central, Dublin West and Dublin Central. I do not think it is necessary for me at this stage to comment further in relation to any of the individual constituencies.
I would like, on behalf of the Government, to express appreciation of the manner in which the commission have done their job and to place on the record of the House our thanks to the members of the commission, Mr. Justice Walsh of the Supreme Court, Mr. Turpin, Secretary of my Department and the Clerk of the Dáil, Mr. Rayel. I am sure that the House will wish to be associated with this expression of appreciation.
I commend the Bill to the House.
