Tips for Businesses

Seek legal advice before making a defamation claim, as litigation costs are significant and defences available to the other party may affect the viability of your claim. Monitor online platforms, review sites, and social media for potentially defamatory content about your business. Document all instances of potentially defamatory material, including dates and the audience who may have seen it, to support any future claim.

Defamation occurs when false information is published about a person in a way that damages their reputation, and it can arise in a wide range of contexts from social media posts to private emails. Understanding what the law requires before bringing a defamation claim is essential. This article explains what can be considered defamatory and the key requirements that must be met under defamation law.

What Can Be Defamatory?

There are a variety comments which can be defamatory, including those that attack someone’s: 

  • personality; 
  • character; 
  • beliefs;
  • personal choices; or
  • mental stability. 

Essentially something is defamatory if it is a malicious comment intended to harm someone’s reputation, and that does not have any grounding in fact.

For the material to be defamatory, it needs to be capable of causing other people to, ultimately, think less of you. Comments regarding physical attributes or appearance are not defamatory. 

Written or spoken comments can be defamatory. The comments can be in print, online, or even in a personal email or social media comment. Whilst many posts and publications can be defamatory, they will need to meet the threshold of requirements set out by defamation law. Let us explore these requirements are below. 

Published Material 

To be considered defamatory, the material must be published or communicated with a third party. If the material is published online, it may be relatively easy to demonstrate that it has been communicated to a third party or is available for anyone to access and view.

However, it is important to note that there is no requirement for the material to be in writing. Defamatory comments can be shared with a third party during a phone call or video conference.

Person is Identifiable  

The second requirement is that the material has sufficiently identified you. The material need not strictly identify you by name, though it makes the element easier to prove. Ultimately, the law will require that an ordinary reasonable person be able to determine that the material is referring to you. 

Damage to Reputation 

Finally, for material to be defamatory, it must genuinely be defamatory. This means the material must lower the person’s reputation or hold them open to ridicule. The position the law takes on this test is by determining what a reasonable person would infer from the comments and where, on this basis, it is likely to damage the reputation of the person the material relates to.
