The Defamation Act (Northern Ireland) 2022 modernised important parts of the law. Online publication creates particular risks because posts can spread quickly, be republished and remain searchable long after the original dispute.
Key points
What to know at a glance
- Do not repeat an allegation casually
- Preserve the full context and reach
- Assess meaning before assuming defamation
- Consider proportionate correction and removal
- Act promptly because time limits are short
What must be defamatory
A statement generally must convey a meaning that lowers reputation in the eyes of reasonable people and cause or be likely to cause serious harm under the statutory framework. Context, audience and the natural meaning of the words matter.
Publication and identification
The claimant must be identified or reasonably understood and the statement communicated to at least one other person. Sharing, reposting or repeating an allegation can amount to a new publication. A disclaimer does not automatically remove the effect.
Defences
Potential defences include truth, honest opinion and publication on a matter of public interest, alongside other protections. Each has detailed requirements. Believing a statement is true is not the same as being able to prove it.
Screenshots and preservation
Preserve the complete post, URL, date, time, comments, reach and account details. Screenshots should show context. Before demanding deletion, consider whether evidence needs to be preserved and whether a measured correction may resolve matters.
Responding without escalating
An angry public response can multiply publication and create fresh allegations. A focused legal letter may seek removal, correction, apology, undertaking or compensation. The strategy should account for the “Streisand effect” and commercial priorities.
Urgency and limitation
Defamation claims have a short limitation period compared with many civil disputes. Injunctive relief is exceptional and fact-sensitive. Seek advice promptly, particularly where publication is continuing or causing immediate professional harm.
