This seminal work, recognised as the authoritative and definitive commentary on Ireland's fundamental law, provides a detailed guide to the structure of the Irish Constitution.

Each Article is set out in full, in English and Irish, and examined in detail, with reference to all the leading Irish and international case law.

It is essential reading for all who require knowledge of the Irish legal system and will prove a vital resource to legal professionals, students and scholars of constitutional and comparative law.

This new edition is fully revised and reflects the substantive changes that have occurred in the 15 years since its last edition and includes expansion and major revision to cover the many constitutional amendments, significant constitutional cases, and developing trends in constitutional adjudication.

The recent constitutional changes covered in this new edition include:

* The 27th Amendment abolished the constitutional jus soli right to Irish Nationality.
* The 28th Amendment allowed the State to ratify the Lisbon Treaty.
* The 29th Amendment relaxed the prohibition on the reduction of the salaries of Irish judges.
* The 30th Amendment allowed the State to ratify the European Fiscal Compact.
* The 31st Amendment was a general statement of children's rights and a provision intended to secure the power of the State to take children into care.
* The 33rd Amendment mandated a new Court of Appeal
* The 34th Amendment prohibited restriction on civil marriage based on sex.
* The 36th Amendment allowed the Oireachtas to legislate for abortion.

New sections include a look at the impact of the Constitution on substantive criminal law, and a detailed treatment of the impact of Article 40.5, protecting the inviolability of the dwelling, on both criminal procedure and civil law.

Other sections have been expanded with in-depth analysis of referendums, challenges to campaigns and results, coverage of Oireachtas privilege, changes in constitutional interpretation, private property rights, and judicial independence. In particular extensive rewriting has taken place on the section dealing with the provisions relating to the courts contained in Article 34 following the establishment of the Court of Appeal and the far-reaching changes to the appellate structure from the 33rd Amendment of the Constitution Act 2013.
