1In the landmark Irish constitutional case of Ryan v Attorney General [1965], the High Court first recognized the existence of unspecified (unenumerated) constitutional rights. Which right was established in this case?

A.The right to marital privacy

B.The right to bodily integrity

C.The right to travel abroad

D.The right to earn a livelihood

Explanation: In Ryan v Attorney General [1965], Kenny J in the High Court held that the personal rights guaranteed in Article 40.3 of the Constitution are not limited to those explicitly listed, but include other 'unenumerated rights' flowing from the Christian and democratic nature of the State. The first right recognized under this doctrine was the right to bodily integrity, in the context of a challenge to the fluoridation of public water supplies.

2Which article of Bunreacht na hÉireann guarantees that justice shall be administered in public, save in such special and limited cases as may be prescribed by law?

A.Article 34.1

B.Article 38.1

C.Article 40.4

D.Article 29.6

Explanation: Article 34.1 of the Constitution of Ireland explicitly states that 'Justice shall be administered in courts established by law by judges appointed in the manner provided by this Constitution, and, save in such special and limited cases as may be prescribed by law, shall be administered in public.' This reflects the fundamental common law principle that justice must not only be done but must be seen to be done.

3In Irish administrative law, what limitation was placed on the rules of standing (locus standi) by the Supreme Court in Cahill v Sutton [1980]?

A.Only the Attorney General has standing to challenge the constitutionality of a statute.

B.A plaintiff must show that their own personal rights have been adversely affected or are in imminent danger of being affected by the law in question.

C.Any citizen has standing to challenge any legislation regardless of whether they are personally affected.

D.Standing is restricted exclusively to corporate bodies or registered interest groups.

Explanation: In Cahill v Sutton [1980], the Supreme Court restricted the rules of standing, rejecting the idea of an actio popularis (where any citizen can sue). Henchy J held that a plaintiff must demonstrate a personal interest or prejudice—specifically, that their own rights have been affected or are in imminent danger of being affected. While exceptions exist for cases of public importance where no other plaintiff is available (e.g., Crotty v An Taoiseach), Cahill remains the baseline authority.

4In the landmark separation of powers case Buckley v Attorney General [1950] (the Sinn Féin Funds case), why did the Supreme Court strike down the Sinn Féin Funds Act 1947?

A.The Act breached European Union law on property ownership.

B.The Act infringed upon the exclusive judicial power to resolve disputes by directing the High Court to dismiss a pending case and distribute funds.

C.The Act violated the constitutional right to freedom of association.

D.The Oireachtas had failed to pass the legislation by the required two-thirds majority.

Explanation: In Buckley v Attorney General [1950], the Supreme Court struck down the Sinn Féin Funds Act 1947 because it directed the High Court to dismiss a pending action and ordered the distribution of the funds. The court held that this legislative interference with active litigation was a clear encroachment by the Oireachtas on the exclusive judicial sphere, thereby violating the separation of powers.

5According to Article 29.4 of the Constitution of Ireland, which body is vested with the executive power of the State in connection with its external relations?

A.The President of Ireland

B.The Taoiseach, acting in their personal capacity

C.The Government

D.The Joint Oireachtas Committee on Foreign Affairs

Explanation: Article 29.4.1 of the Constitution provides that 'The executive power of the State in or in connection with its external relations shall in accordance with Article 28 of this Constitution be exercised by or on the authority of the Government.' This places foreign policy and external relations squarely within the executive powers of the Cabinet.

6Under the rules of constitutional justice and fair procedures in Irish administrative law, what is the meaning of the Latin maxim 'audi alteram partem'?

A.No one should be a judge in their own cause.

B.The law does not concern itself with trifles.

C.Hear the other side (or the right to a fair hearing).

D.An act does not make a person guilty unless their mind is also guilty.

Explanation: The maxim 'audi alteram partem' translates to 'hear the other side'. It is one of the two core pillars of natural justice / constitutional justice. It requires that a decision-maker must give any person whose rights or interests may be affected by a decision adequate notice of the allegations against them and a fair opportunity to make representations or respond.

7In Bula Ltd v Tara Mines Ltd [2000], the Supreme Court articulated the test for objective bias in administrative decision-making and judicial hearings. What is this test?

A.Whether the decision-maker actually intended to favor one party over another.

B.Whether a reasonable, objective, and informed observer would have a reasonable apprehension that the decision-maker might not bring an impartial mind.

C.Whether the decision-maker has a direct financial interest in the outcome of the dispute.

D.Whether the decision-maker has a familial relationship with any of the litigants.

Explanation: The test for objective bias established in Bula Ltd v Tara Mines Ltd [2000] is whether a reasonable, objective, and informed observer would have a reasonable apprehension that the decision-maker might not bring an impartial mind to the resolution of the question. Actual bias does not need to be proven; the appearance of bias is sufficient to invalidate the decision because public confidence in the administration of justice is paramount.

8In State (Keegan) v Stardust Victims Compensation Tribunal [1986], the Supreme Court established the Irish standard for judicial review on the grounds of unreasonableness (irrationality). How is this standard formulated?

A.The decision is invalid if the court disagrees with its merits or would have reached a different conclusion.

B.The decision must fly in the face of fundamental reason and common sense, such that no reasonable authority could ever have made it.

C.The decision is invalid if it violates any policy objectives of the ruling government.

D.The decision must be shown to have been influenced by political corruption.

Explanation: In Keegan [1986], Henchy J formulated the Irish standard for unreasonableness (irrationality), drawing on the English Wednesbury principle. He held that for a decision to be struck down on this ground, it must be shown that the decision-maker acted in disregard of fundamental reason and common sense, such that no reasonable authority could have reached that decision. This is a very high threshold designed to prevent the courts from acting as a court of appeal on the merits of administrative decisions.

9Under Article 26 of Bunreacht na hÉireann, what is the procedure when the President refers a Bill to the Supreme Court?

A.The President refers the Bill after it has been signed into law to test its validity.

B.The President refers the Bill after consulting the Council of State, before signing the Bill, to determine if it is repugnant to the Constitution.

C.The Supreme Court drafts amendments to the Bill to make it constitutional.

D.The Bill is referred to the European Court of Justice for an advisory opinion first.

Explanation: Under Article 26, the President may, after consultation with the Council of State, refer any Bill (with exceptions like Money Bills or urgent Bills) to the Supreme Court before signing it. The Court must decide whether the Bill or specified provisions are repugnant to the Constitution. If the Court finds any provision repugnant, the President must decline to sign the Bill. If the Court upholds the Bill, it becomes law, and its constitutionality can never be challenged again in any court (Article 34.3.3).

10Under Article 13.2.2 of the Irish Constitution, the President possesses a rare personal discretionary power to refuse a dissolution of Dáil Éireann. In what circumstance can this power be exercised?

A.When the Taoiseach advises dissolution, but the President believes a general election is too expensive.

B.Only when the Taoiseach has ceased to retain the support of a majority in Dáil Éireann.

C.When the President wishes to appoint a different political party to form a government without an election.

D.When the Senate (Seanad) objects to the dissolution.

Explanation: Article 13.2.2 states: 'The President may in his absolute discretion refuse to dissolve Dáil Éireann on the advice of a Taoiseach who has ceased to retain the support of a majority in Dáil Éireann.' If the Taoiseach retains a majority, the President must grant the dissolution. This discretionary power has never been formally exercised in the history of the State, though it has been close to being invoked during governmental collapses.
