Can social media posts and chat messages be used as evidence in Court?

Messaging and social media applications such as Facebook and WeChat have become an indispensable part of our life, from daily conversations to business negotiations, people can discuss almost anything on them. So can chat records be used as evidence in court? Today we will briefly examine whether social media posts and chat messages can be used as evidence or not.


Social media

In the past, cases were generally conducted mainly through oral evidence, that is, through examination in chief and cross-examination of witnesses, affidavits, and other relevant documents such as contracts, leases, etc. With the increasing popularity and accessibility of social media and mobile devices , we see more and more evidence gradually transforming into so-called “made” evidence such as chat history and screenshots.


Hearsay evidence

However, courts do not always accept chat records, screenshots, and posts as reliable evidence. Generally, your conversation with anyone on social media will be regarded as documentary evidence. However, these conversations or screenshots are usually regarded as hearsay evidence by the court, and generally inadmissible unless it can be tendered through a witness or fall within an exception listed in the relevant legislation. On the other hand, data generated by any server, such as time and place, will generally be recognised as real evidence.

However, due to the popularity and convenience of social media, many commercial activities have engaged in publicity work and negotiation directly via social media. In a 2017 case, HOMART PHARMACEUTICALS PTY LTD v CARELINE AUSTRALIA PTY LTD, private and group conversations in WeChat as well as advertisements posted were accepted as evidence by the court and played an important role in the case.Furthermore, in the case of Bauer Consumer Media Ltd v Pty Ltd, the only evidence the court relied upon were social media and websites provided by both parties.


Your social media posts can also be detrimental to your case 

It is important to note that information or posts you make on social media platforms can act in your favour in a matter but others may also rely on it to  used it against you in a dispute or proceeding.

For example

Ms. Lee claimed that a car accident caused impairment to her cognitive function, diminished her decision-making ability and concentration, and caused excessive stress that prevented her from maintaining social relationships. The case was going smoothly until the other side provided evidence regarding Ms. Lee’s social media posts. Ms. Lee regularly updates her account to document her busy social life She was also an enthusiastic Facebook gamer and posted many impressive high scores she had earned in the game. The evidence provided was clearly contradicting Ms. Lee’s previous claims. Consequently, the final judgement was far from what she expected.
