The Taoiseach must be nominated by the Dáil, the house of representatives. Following the nomination of the Dáil, the President of Ireland appoints the Taoiseach to their role. The President also appoints members of the government, including the Tánaiste, the deputy head of government, on the nomination of the Taoiseach and their approval by the Dáil. The government is dependent on the Oireachtas to pass primary legislation and as such, the government needs to command a majority in the Dáil in order to ensure support and confidence for budgets and government bills to pass.
Since the formation of the 12th Government of Ireland in 1966, all Irish cabinets have been formed with the constitutional maximum of fifteen ministers. The total sometimes falls below this number for brief periods following the resignation of individual ministers or the withdrawal of a party from a coalition.
Non-members have no voting rights at Cabinet but may otherwise participate fully, and normally receive circulated Cabinet papers on the same basis as a full member of Government. Votes are rare, however, with the cabinet usually following the Taoiseach or working by consensus.
The Government is advised by the Attorney General, who is not formally a member of the Government, but who participates in cabinet meetings as part of their role as legal advisor to the Government.
A new government is formed by the Taoiseach appointed after each general election after receiving the nomination of the Dáil. All members of the government are deemed to have resigned on the resignation of the Taoiseach. Therefore, a new government is appointed where there is a new Taoiseach within a single Dáil term. The Constitution allows a Dáil term of no more than seven years, but a shorter period may be specified by law; this has been set as a maximum of five years. The Taoiseach may at any time advise the President to dissolve the Dáil, prompting a new general election.[17] The President retains absolute discretion to refuse to grant a dissolution to a Taoiseach who has lost the confidence of the Dáil.[18] To date, no President has refused the request of a Taoiseach to dissolve the Dáil.
The Taoiseach must retain the confidence of Dáil Éireann to remain in office. If the Taoiseach ceases "to retain the support of a majority in Dáil Éireann", the Taoiseach must resign unless they seek a dissolution of the Dáil which is granted by the President. This applies only in cases of a motion of no confidence or loss of supply (rejection of a budget), rather than the defeat of the government in other legislation or Dáil votes.
The Taoiseach can direct the President to dismiss or accept the resignation of individual ministers. When the Taoiseach resigns, the entire Government is deemed to have resigned as a collective. However, in such a scenario, according to the Constitution, "the Taoiseach and the other members of the Government shall continue to carry on their duties until their successors shall have been appointed".
On the dissolution of Dáil Éireann, ministers are no longer members of the Oireachtas. However, the Constitution also provides that "the members of the Government in the office at the date of a dissolution of Dáil Éireann shall continue to hold office until their successors shall have been appointed".[19]
Caretaker Government
Where the resignation of the Taoiseach and government is not immediately followed by the appointment by the president of a new Taoiseach on the nomination of the Dáil, the outgoing government continues as a caretaker government to "carry out their duties until their successors have been appointed". This has happened when no candidate was nominated for Taoiseach when the Dáil first assembled after a general election, or, on one occasion, where a Taoiseach had lost the confidence of the Dáil, but there was not a dissolution of the Dáil followed by a general election.
Unlike the cabinets in other parliamentary systems, the Government is both the de jure and de facto executive authority in Ireland. In some other parliamentary regimes, the head of state is the nominal chief executive, though bound by convention to act on the advice of the cabinet. In Ireland, however, the Constitution explicitly vests executive authority in the Government, not the President.
The executive authority of the Government is subject to certain limitations. In particular:
The state may not declare war, or participate in a war, without the consent of the Dáil. In the case of "actual invasion", however, "the Government may take whatever steps they may consider necessary for the protection of the State".
Government ministers are collectively responsible for the actions of the government. Each minister is responsible for the actions of his or her department. Departments of State do not have legal personalities. Actions of departments are carried out under the title of ministers even, as is commonly the case when the minister has little knowledge of the details of these actions. This contradicts the rule in common law that a person given a statutory power cannot delegate that power.[30] This leads to a phrase in correspondence by government departments, "the Minister has directed me to write", on letters or documents that the minister in question may never have seen.
If the Government, or any member of the government, should fail to fulfil its constitutional duties, it may be ordered to do so by a court of law, by a writ of mandamus. Ministers who fail to comply may, ultimately, be found to be in contempt of court, and even imprisoned.
The detail and structure of the Government of Ireland has its legislative basis in the Ministers and Secretaries Act 1924; it has been amended on a number of occasions, and these may be cited together as the Ministers and Secretaries Acts 1924 to 2017 and are construed together as one Act.
All governments from 1989 to 2016 were coalitions of two or more parties. The first coalition government was formed in 1948. The Taoiseach has almost always been the leader of the largest party in the coalition, with the exceptions of John A. Costello, Taoiseach from 1948 to 1951 and from 1954 to 1957 (a member of Fine Gael but not the party leader) and Leo Varadkar, since 2022 (leader of Fine Gael, in a three-party coalition where Fianna Fáil is the largest party).
The largest sector is the health sector with over 105,000 employees (largely in the Health Service Executive), followed by the education sector with approximately 98,450.[31]
The civil service of Ireland consists of two broad components, the Civil Service of the Government and the Civil Service of the State. While this partition is largely theoretical, the two parts do have some fundamental operational differences. The civil service is expected to maintain political impartiality in its work, and some parts of it are entirely independent of Government decision making.
Simon Harris was nominated as Taoiseach by Dáil Éireann on 9 April 2024 and appointed by the president. Harris proposed the nomination of the members of government, and after their approval by the Dáil, they were appointed by the president.
