I don't believe this is real. The prosecutions were for transgressing specific laws (Misuse of Communications Act as well as other Acts). There have categorically not been prosecutions for simple "false information".
While the riots were
stoked by misinformation, there was no arrest or prosecution to my knowledge simply about spreading or posting this misinformation.
The offences connected to social media posts involved "using threatening words or behaviour
intending to stir up racial hatred". The operative word here is "
intending to". In each case that I'm aware of the defendant pleaded guilty to the offence - and in so doing - they admit that it was their "
intent" to either "stir up racial hatred" or "encourage activity which threatened or
endangered life"
Here's a link to the Judges closing statements in sentencing in the case of Rex vs Connolly
Lucy Connolly - Intent to encourage activity which endangered life
Ignorance or knowledge that information is false is irrelevant here, since there is no offence about spreading misinformation.
The act of
intending to stir racial hatred or
intending to incite violence are how offences are measured.
In all cases, proving
intent in a courtroom is extremely difficult. However, if the defendant pleads guilty, then the intent is established to be a fact at that point. In each case the defendants were also advised by qualified counsel. The counsel in each case would only have advised them to plead guilty if the evidence was highly likely to point towards and prove beyond doubt, that intent was present. Pleading guilty also gets a discount off the sentence.
(For context I was an Assisting Officer to a defendant in a case of Misuse of Communications Act last year. The case hinged entirely upon the proof of intent. Very well respected counsel didn't advise a guilty plea. However, the defendant was found guilty in court only due to a chain of factors - namely the communication was "grossly offensive; AND
intended to cause distress.)
