The Irish Yearbook of International Law supports research into Ireland's practice in international affairs and foreign policy, filling a gap in existing legal scholarship.

This new volume covers the years 2021 and 2022, including global events such as the COVID-19 pandemic, Brexit fall-out, the Taliban's return to power in Afghanistan, a civil war in Ethiopia, protests in Iran, and Russia's unlawful invasion of Ukraine. Reports also cover topics on human rights in Ireland, the law of the sea, the exploitation of mineral resources of celestial bodies by private enterprises and the protection of the right to food, among others.

Additionally, the book includes four book reviews covering a range of international law subjects, such as international economic law, colonialism and the protection of animals in armed conflict.
