The legal framework

The Defamation Act 2009 governs, with defences of truth, honest opinion and fair and reasonable publication. Reform legislation to abolish juries in High Court defamation actions and to address strategic lawsuits has been progressing. Coco's Law — the Harassment, Harmful Communications and Related Offences Act 2020 — criminalised sharing intimate images without consent.

As a member state of the European Union, platforms operating here are subject to Regulation (EU) 2022/2065: notice, reasons and appeal are European, while the definition of what is illegal remains set by national law.

In practice

Cost and coverage

Defamation proceedings are costly; reporting under Coco's Law is free through the Gardaí.

Recent changes

Coimisiún na Meán, established in 2023, became Ireland's online safety regulator and is the national coordinator under the EU Digital Services Act.

Where to go

Worth knowing

Coco's Law covers threats to share images as well as actual sharing — a threat alone is an offence and can be reported immediately. Irish defamation awards have historically been high, which makes both claiming and defending expensive. Reform has been under discussion for years.
