Main article: Judicial review in Ireland
The Supreme Court exercises, along with the High Court the power to strike down laws that are inconsistent with the Constitution. The courts also injunctions against public bodies, private organizations and citizens to ensure that the Constitution. The Irish constitution explicitly provides for judicial review of legislation. Acts passed after the entry into force of the Constitution, is invalid if “repugnant” to the Constitution,  while the laws in force before the entry into force of the Constitution is invalid if “inconsistent” with the Constitution.  The Constitution also provides, in accordance with Article 26, for judicial review of bills before they are (or would have been) signed into law. The power to refer bills personally exercised by the President after consulting the Government. When the Supreme Court upholds the constitutionality of a bill referred to in Article 26, its constitutional law can not be challenged in court at any time. 
Supreme Court judges are normally free to deliver their own assessments, divergent and convergent. There is an exception when considering the constitutionality of a bill referred by the President under Article 26 of the Constitution, where only a single judgment may be delivered.  Previously, the only judgment rule even when considering the constitutionality of a law by the Oireachtas passed under 1937 Constitution, this was removed by the 33rd Amendment to 2013. Acts passed prior to 1937 has always permitted several judgments. [n 1]
After a slow start during the first two decades of the Constitution, the Supreme Court has rendered a significant constitutional jurisprudence. This slow start was in part because, before 1922, all of Ireland was part of the United Kingdom, and the Supreme Court judges had been trained in British jurisprudence, which stresses the sovereignty of Parliament and respect the legislature. It was also true that the 1922 Constitution was a right of appeal to the Privy Council to bear on a number of occasions. Nevertheless, from the 1960s onwards, the Court has made a number of important decisions. It has, for example:
- Developed a doctrine of unenumerated rights based on an expansive interpretation of Article 40.3.1 °, with elements of natural law and liberal democratic theory.
- Developed and defended the separation of powers.
- Ruled that major changes to the Treaties establishing the European Union can not be ratified by the state is not allowed under a previously passed constitutional amendment.
- Ruled that Articles 2 and 3 (as they stood before 1999) does not impose obligations on the state that was enforceable in a court of law.
- Discovered a broad right to privacy in marital affairs implicit in Article 41.
- Discovered a right to abortion where there is a risk to the mother’s life by suicide in Article 40.3.3 °.

Today the Supreme Court shares his authority with two supra-national courts: the Court of Justice (ECJ) and the European Court (ECHR). In matters concerning the correct interpretation of EU law, decisions of the European Court of Justice has precedence over the provisions of the Irish Supreme Court.
The relationship between the Irish courts and the European Court is more complicated. The European Convention on Human Rights, a treaty is binding on the state of international law. But as a matter of Irish national law, the Convention is inscribed only in law, and not the status of the constitution.Under the terms of the European Convention on Human Rights Act, adopted by the Oireachtas in 2003, ordinary law must where possible, be interpreted in accordance with the Convention. But the Irish courts the Convention must give way both clear legislative intent and any countervailing demands on the Constitution. Moreover, its provisions are not invoked as separate causes of action.
Supreme Court decision can not be appealed, as such, either the courts. The court hears cases referred to it by the Irish courts by a preliminary ruling and while unsuccessful litigants before the Supreme Court can apply to the European Court, not later Court decision does not mean that emptying the Supreme Court decision. As a matter of Irish national law decisions of the European Court does not automatically override the Oireachtas documents and may require legislative or perhaps even a constitutional referendum to be implemented in its entirety.
