The restrictions on civil servants engaging in political activity operate at two levels; legislative and administrative. Under the Electoral Acts no civil servant may be elected to or sit as a member of Dáil Éireann. Administrative rules on civil servants and political activity fall into two categories; restrictions on standing for election to political office and rules regarding the maintenance of political impartiality. Restrictions on civil servants standing for election are set out in circulars of 1925, 1934 and 1974. The restrictions were relaxed somewhat by the Government in 1974 and the current arrangements are as follows: (a) Civil servants are not permitted to stand for election to either House of the Oireachtas or to the European Assembly. This restriction applies to all categories of staff. (b) Civil servants in the industrial and in the manipulative, sub-clerical and manual grades are free to engage in political activity, subject to the general restriction in relation to parliamentary elections. Civil servants in this category may, therefore, contest local elections. (c) Members of the clerical grades in the civil service and civil servants in non-manipulative grades with salary maxima equal to or below the clerical officer maximum may apply for permission to engage in politics on the same basis as the staff referred to at (b) but officers employed on particular types of work may have their applications refused. (d) All civil servants above clerical level are totally debarred from engaging in politics. However, personal assistants and special advisers in Ministers' offices, whose terms of appointment are coterminous with those of the relevant appointing Minister, are exempt from the present arrangements covering State employees and politics.
